Do You Know How Your Company’s Brand is Perceived in the Marketplace?


Do You Know How Your Company’s Brand is Perceived in the Marketplace?

Your brand defines who you are and what kind of experience you want to deliver to your clients. It can also be what sets you apart from your competition.

By Karen Edwards, RCS Editor

You probably know a lot of popular brands and have varying opinions about them based on your personal experience or perception of the brand.

Since you are at the Coffee Shop right now, let’s take a look at coffee as an example of two brands that provide the same product but are very different. Two famous coffee brands are Dunkin Donuts and Starbucks (listed alphabetically and not necessarily in order of the writer’s preference). These two brands have very loyal followers who rarely stray from their preferred taste – Dunkin Donuts’ coffee is perceived as milder and more mainstream than Starbucks.

But it’s about more than preferred taste. It’s also about the customer experience. The experience that these two brands provide for their customers is very different. “America Runs on Dunkin’” has set the stage for a place where you can stop at a shop, grab some coffee and donuts and be on the go. The Starbucks experience is about interacting with baristas and relaxing on casual furniture with soft lighting while reading or chatting with friends. These are two very different experiences and brands, yet both provide the same deliverable – coffee.

You have competitors in your market that are providing the same roofing services as you, but you can set yourself apart from your competitor through your brand experience. Just as you have perceptions about brands, your customers have perceptions of your roofing business. So how do you want to be perceived in the markets that you serve? What kind of experience do you want your customers to have? How is your brand currently perceived in your service area?

Answering the question of how your brand is currently perceived can be difficult. When you live your brand every day, you often don’t see it the same way as your customers and potential customers might see it. The best way to find out is to consider conducting a brand survey. The results can help you fine tune your brand and turn it into your point of differentiation.

In fact, that’s exactly what RoofersCoffeeShop.com partner, Acme Cone Company is currently doing. They are conducting a brand survey.  Answer 12 quick questions about them and they’ll give you a $5 gift card for your time. That will buy you at least one cup of coffee! You’ll also get an idea of the kinds of questions you can ask about your brand at the same time.

Take the survey.

Looking for a Roofing CRM? | FCS Tip #2: The Right Questions to Ask


Looking for a Roofing CRM? | FCS Tip #2: The Right Questions to Ask

Tip #2: Questions to Ask About Customer Data & Roofing CRM.

By FCS Roofing Software.

  • Does the program work for residential and commercial business?
  • Can I track projects, estimates and quotes by customer?
  • Can I integrate it with other software in order to track the entire customer experience?

There are several roofing CRM systems – many of them integrated with project management software. But first you may be asking – what is a CRM? It is a Customer Relationship Management system and it could be Microsoft Outlook, an Excel file or a higher-level software specifically designed for the roofing business.

Some systems offer customer portals where you can share data, photos, job progress, inspections and invoices with customers at their convenience. This type of CRM can be used for initial customer contact and sales with the scalability to store all of the customer’s projects as they grow with the company. This type of system is usually used more with commercial business. It is also a great tool to use if you are focused on HOA work.

Whichever CRM you use, the key is to maintain a strong, up-to-date customer database that becomes not only a historical view of your customers and projects but also a strong database for future sales and marketing. By using a CRM software instead of Outlook, Excel or a Rolodex, recording customer communication can be automated, including: notes, past correspondence, property data, material preferences and/or potential future projects.

Ask FCS a question at (855) 633-3327 or info@fcscontrol.com.

Those who wish to donate may do so at  www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=5RN4VQ75LDH2E.

In addition, NRCA member Beldon Roofing Co., San Antonio, has alerted NRCA the San Antonio Food Bank is in immediate need of monetary donations to help feed the thousands of Houston’s residents who have fled to the hurricane. Contributions can be made at www.safoodbank.org.

NRCA and The Roofing Industry Alliance for Progress’ Helping Our Own program will each be making $1,000 contributions to both organizations.

There also are countless additional organizations that have established campaigns to support those in Hurricane Harvey’s path. Following are a few.

American Red Cross

Feeding Texas

Salvation Army

Society for the Prevention of Cruelty to Animals (SPCA) of Texas

Greater Houston Community Foundation

United Way of Greater Houston

There are countless additional charitable agencies across the U.S. that have established funds to aid those affected by this terrible hurricane. NRCA continues to closely watch the hurricane as it progresses, and will alert the roofing industry of additional fundraising plans.

Thank you in advance for your generosity to those affected by this devastating event.

PetersenDean Roofing & Solar Selects GAF as Preferred Manufacturer of Cool Shingles

FREMONT, Calif. – Fremont, California-based PetersenDean Roofing & Solar announced its relationship with GAF, North America’s largest roofing manufacturer. The relationship will help supply PetersenDean consumers in all of its seven operating states with shingles that can be used to comply with Title 24 cool roof requirements.

GAF is an American owned company with headquarters in Parsippany, N.J., and more than 30 manufacturing facilities nationwide.  

“We selected GAF because they own an expansive network of manufacturing facilities and produce quality products that make the company a leader in the industry,” said Gary Liardon, president of US Consumer Division, PetersenDean Roofing & Solar. “With all of GAF’s plants based in the U.S., we are providing our customers with quality products and supporting American jobs. They also produce the popular shingle colors that our customers like and offer comprehensive warranties. We are proud to partner with such an innovative and dependable manufacturer.”

GAF is the only roofing manufacturer to earn the Good Housekeeping Seal of Approval on its products. The company recently introduced its Timberline HD® Reflector Series™ Shingles, which can be used to comply with Title 24 cool roof requirements. Cool roofs reflect more sunlight and absorb less heat than traditional roofs to help keep your home cooler. Additionally, GAF offers its Timberline HD® Reflector Series™ Shingles in a large selection of colors with comprehensive warranties. The color selection and warranties will provide PetersenDean customers with choice, quality, and peace of mind.

“At GAF, we are committed to working with the best contractors in the industry,” said Todd Tarchalski, West area vice president of sales at GAF. “We couldn’t be more excited to work with PetersenDean, one of America’s largest and most trusted roofing and solar companies.”

The GAF products will be offered in all seven states where PetersenDean operates.

This relationship helps meet two important goals for PetersenDean, which installs about 2,000 solar and roof systems each month nationally: providing PetersenDean customers with quality, innovative roofing materials and supporting American jobs.

“We made a decision at PetersenDean to only source our products from manufacturing facilities in North America,” said Jim Petersen, president and CEO of PetersenDean Roofing & Solar. “That’s why we chose to utilize GAF, which owns multiple manufacturing facilities across the nation. We can help customers lower their electric bills, help the environment, and help the economy.”

PetersenDean is the nation’s largest privately held solar and roofing company and is known for its advanced solar system technology and its American-made solar and roofing products.

SEBS Roof Coating System Designed for Use in Variety of Applications


SEBS Roof Coating System Designed for Use in Variety of Applications

Mule-HideThe new SEBS Roof Coating System from Mule-Hide Products Co. combines high tensile strength, excellent elasticity, ultra-low moisture permeability and resistance to ponding water, making it an ideal choice for use in a wide variety of challenging roof repair and restoration applications, according to the manufacturer.
 
The solvent-based coating system is designed primarily for use in repairing and restoring metal roofs, but also can be used on TPO, EPDM, asphalt, modified bitumen, Kynar, concrete, Hypalon and PIB roofing systems.
 
The SEBS Roof Coating System includes the following products: SEBS Primer; SEBS Base Coat; SEBS Roof Coating (for use on metal, TPO and Hypalon roofing systems); SEBS+ Roof Coating (for use on metal, TPO, Hypalon, EPDM, asphalt, modified bitumen, Kynar, concrete and PIB roofing systems); SEBS Seam Sealer; and SEBS 1 – Multipurpose Sealant.

The coatings’ solvent base and ultra-low moisture permeability enable them to outperform other coating types in ponding water applications, according to the manufacturer. They will not delaminate if the substrate becomes wet and, unlike water-based coatings, they will not re-emulsify during prolonged exposure to ponding water.

The lack of permeability also helps prevent corrosion of metal substrates and makes the coatings highly resistant to algae and fungi. Antioxidants and light stabilizers ensure the coating system’s durability throughout the roofing system’s service life.

Because the SEBS Roof Coating System is solvent-based, it cannot be shipped to areas that regulate the use of products containing volatile organic compounds (VOCs).

Beacon Roofing Supply to Acquire Allied Building Products


Beacon Roofing Supply to Acquire Allied Building Products

Beacon Roofing Supply Inc. announced that the company has entered into an agreement to acquire Allied Building Products Corp. Beacon will purchase Allied from global diversified building products group CRH for $2.625 billion in cash.

Headquartered in Herndon, Va., Beacon is a distributor of residential and non-residential roofing and complementary building products, and the company currently has more than 380 locations in 48 states and six Canadian provinces.

Allied is headquartered in East Rutherford, N.J., and distributes products across 208 locations in 31 states. The company distributes exterior products, such as roofing, siding, windows and doors, and interior products, such as wallboard and suspended ceiling systems.

According to Beacon, the combination of Beacon and Allied will make Beacon one of the largest publicly traded wholesale building materials distributors in North America with pro forma revenues of approximately $7 billion and 593 branches in all 50 states and six provinces across Canada.

Beacon will also become the fourth largest wallboard and acoustical ceiling tile wholesale distributor in the United States, with more than $1 billion of revenue in the interior market category. Beacon and Allied have more than 150 years of combined experience providing service excellence to customers in the building products industry.

Beacon expects to finance the acquisition with approximately $2.2 billion of debt financing, a new unsecured note and approximately $500 million of committed convertible preferred equity financing from an entity affiliated with the investment firm Clayton, Dubilier & Rice (CD&R), which in October 2015 sold Roofing Supply Group (RSG) to Beacon. The parties currently expect to consummate the transaction on or around January 2, 2018, subject to satisfaction of customary closing conditions.

Robert R. Buck, chairman of Beacon’s board of directors, stated: “Allied is among the most established and respected companies in our industry, and we are proud that, through this acquisition, Beacon will become one of North America’s largest publicly traded building materials distributors and will operate locations in all 50 states. I want to thank CRH for entrusting Beacon with the future success of Allied and its dedicated employees, who have been part of the CRH family for more than 20 years. The Allied acquisition also presents a great opportunity for CD&R to again become a major shareholder in Beacon. Today is of great significance in Beacon’s history and for the future of building products distribution.”

Paul Isabella, Beacon’s president and chief executive ffficer, commented: “I would like to welcome the more than 3,500 employees from Allied to the Beacon family. We are thrilled to partner with such a loyal and dedicated workforce that shares our commitment to superior customer service and high levels of performance. We are also excited to become a significant player in the robust, growing and still-consolidating interior products market. Together, we will leverage the strengths of both companies, while remaining committed to preserving the deep customer relationships that we have each cultivated over 150 years of combined experience. This is a milestone moment in the long and successful histories of both companies.”

Tennessee Association of Roofing Contractors Association Raises $14,000 to Aid Families Affected by 2016 Wildfires


Tennessee Association of Roofing Contractors Association Raises $14,000 to Aid Families Affected by 2016 Wildfires

CHL_4265 copyOn April 21, members of the Tennessee Association of Roofing Contractors (TARC) hosted a golf tournament in Gatlinburg, Tenn. to raise funds for Gatlinburg’s Mountain Tough Recovery Team (MTRT), a foundation set up through the East Tennessee Foundation to help families who lost homes in the wildfires that spread through the state in late 2016.

MTRT was created to aid and support families who were adversely affected by the fires on November 28, 2016, that burned 1,800 homes and caused $500 million in damage to the tourism industry.

“It’s important for TARC to support the businesses in Tennessee, especially in times of need,” says TARC past-president Robert Smith, Jr. “There are still families displaced by these fires and businesses yet to be rebuilt.”
In lieu of TARC’s Scholarship Fund, TARC held a special silent auction and reception after the golf tournament to raise funds for fire victims. Items auctioned included Gatlinburg weekend getaway packages donated by the Gatlinburg Visitors Bureau.

TARC exceeded its goal of raising $10,000 for the foundation, raising $14,000.

“The MTRT will utilize these funds to assist the fire survivors with various unmet needs from medical assistance, the replacement of items such as small appliances to be used for food preparation, and assistance with utility costs in temporary housing,” said MTRT board chair Ellen Wilhort.

“It was a touching experience,” Smith says. “To be able to be part of the rebuilding process in these people’s lives made the event worthwhile. We as an organization should be honored to have been able to lend a hand to those in need.”

Q&A with Vickie: Angie Hicks, co-founder of Angie’s List


Q&A with Vickie: Angie Hicks, co-founder of Angie’s List

Angie’s List has added free educational webinars and is increasing their presence at industry events in order to talk one-on-one with roofing contractors.

Recently, Vickie Sharples had the good fortune to ask Angie Hicks, co-founder of Angie’s List, a few questions.  We were curious to learn more about their new program changes and what advertising and marketing opportunities they had for the roofing community.  She graciously reviewed some of the resources Angie’s List is offering with us.

Vickie: You are reaching out to the roofing community with a different program than you had in the past. This new program seems to give more contractors greater opportunities on Angie’s List. How is this new format different from other lead and referral companies?

Angie: Angie’s List is distinct in three ways: high-quality members, trusted reviews, and strong brand recognition. Our members are overwhelmingly homeowners, and 88% of them hired a contractor in 2016, spending an average of $7,200.1

Our reviews are audited annually by a third-party vendor called BPA Worldwide, which helps to ensure that our review processes are fair and unbiased. Pros may not review themselves or their competitors, our reviews are never anonymous, and Pros have the chance to respond to reviews left on their business.

In addition to our members and reviews, Angie’s List is the home-service industry’s most recognized brand for customers looking for home-improvement services. Angie’s List has the highest awareness among home service companies – 94% of consumers recognize the Angie’s List brand.2

Vickie: We have seen resources such as free marketing webinars on your business center. What are some of the other things you are doing to help contractors, specifically roofing contractors?

Angie:  First, I’m glad you recognized our webinars. These are a relatively new initiative, and we’re excited to add value to a Pro’s interaction with Angie’s List. We’ve been in business with service companies for more than 20 years, and the webinars are a great way to share the expertise we’ve gained and help Pros grow their business. Our next webinar is August 23rd, and the topic is all about reviews. The goal is to help Pros become experts on collecting and responding to reviews so that they can increase their business’s exposure and communicate with their customers with ease.

In addition to the webinars, we’re increasing our presence at industry trade shows and hosting regional networking events for Pros across the country. For example, we recently held a networking event at TopGolf in Houston, Texas, where service pros could share best practices, learn from our own industry experts, play golf, and enjoy food and beverages, while getting to speak face-to-face with Angie’s List representatives. It was a lot of fun, both for the Angie’s List employees and for the Pros, and we look forward to meeting more of our customers across the country as we host more of these networking nights. Keep a lookout for our booth at your next trade show, and an eye on your email for a networking event in your area!

Vickie: We have noticed that you have listings of roofing contractors that are in your system ready for the owner of that company to claim his listing. The sign-up seems pretty painless. Can you tell us a little about the process and how it is working so far?

Angie: As soon as an Angie’s List member leaves a review for a service provider who isn’t yet listed on Angie’s List, we email that service provider to let them know they’ve earned their first Angie’s List review! Pros can follow the link in that email directly to a page where they can claim their business and start building their Angie’s List profile. We want to make it as simple as we can for service providers to officially register their company on Angie’s List, so even if they haven’t yet earned a customer review, but would like to build an Angie’s List profile and start collecting reviews, all a Pro would have to do is call 1-866-843-LIST or visit this link.

Vickie: Besides the listing opportunities, what other marketing resources does Angie’s list provide specifically for roofing contractors?

Angie: We actually have a number of opportunities for roofing contractors to get in front of our members. In addition to an online presence, Angie’s List offers advertising in our award-winning magazine, which is sent to members each month and offers the chance to stand out from the competition online. There’s also the opportunity to connect with members through our weekly emailed newsletter. Our Client Success Managers are adept at helping Pros determine and develop the best strategy to get the most value from Angie’s List resources and opportunities.

Vickie: If we are a contractor that uses Angie’s list do you provide insight into the responses submitted by homeowners?

Angie: Any Pro who is registered with Angie’s List has full visibility of all reviews left on their profile, as well as the ability to respond. Using this interaction between member/client and the Pro is a great opportunity to enhance a company’s brand by showcasing responsiveness, thoughtfulness, and caring.

Additionally, the Angie’s List Business Center now features a “Pro Dashboard” where Pros can see summary metrics of their Angie’s List profile performance, such as the number of recent reviews collected and the number of recent profile views they’ve received.

Cool Roofs are a Compelling Choice in the North


Cool Roofs are a Compelling Choice in the North

Dark Roof’s Summer Cooling Penalty is a Deciding Factor

Cool roofs reflect the sun’s energy and reduce air conditioning loads in the summer, so do dark roofs absorb energy in the winter and reduce heating costs? In northern regions where heating costs are significant, can dark roofs be energy efficient? Some building professionals specify dark absorptive membranes for northern cities like Chicago and Minneapolis believing that they are lowering their clients heating costs and lowering year round energy costs.

An analogy, only slightly tongue in cheek, would be to ask if Chicagoans walking along Michigan Avenue in the winter wear dark clothes to stay warmer? Or do dark colored cars outsell light colors in the Windy City?

So, do dark roofs help improve building energy efficiency in northern cities? Let’s take a look at the arguments.

Heating Degree Days versus Cooling Degree Days

There is no doubt that heating degree days in northern areas are far greater than cooling degree days. For example:

Cooling Days

This means that the number of days the temperature was below 65°F multiplied by how many degrees the temperature was lower, was 9,317. This far outnumbers the cooling degree days and some have argued that therefore dark roofs are appropriate for northern cities such as Minneapolis. However, it’s important to examine the cost of cooling versus the cost of heating.

Energy Costs

Data from the U.S. Energy Information Administration for commercial customers in Minnesota in 2015 allows us to compare the cost of heating versus cooling. Assuming gas as the energy source for heating:

BTUs

Added to this, cooling is less efficient than heating. This means that one can’t simply compare the number of heating versus cooling degree days to make a judgment.

Verdict

Degree day comparisons don’t enable a choice of roof reflectivity to be made. Put simply, neither EPDM nor TPO / PVC can be specified on the basis of the number of heating degree days versus those of cooling degree days.

Cooling versus Heating Costs

Heating – Gas Costs

Natural gas is becoming ever more plentiful in the US and costs are fairly stable meaning that heating costs can generally be budgeted for with confidence. Added to that, utilities usually charge commercial customers a flat amount per cubic foot used. Frequently, volume discounts apply and larger customers pay less per BTU of heat than smaller ones.

Cooling – Electricity Costs

Today’s electric bills, especially for commercial and industrial customers, are fairly complex. However, the basic components are as follows:

  • Base Use Rate – the charge per kilowatt hour (kWhr) of energy use.
    • This is common for residential but rare for commercial customers.
    • Can vary depending on the time of year, eg. summer versus winter.
  • Time of Use Rate – the charge per kWhr of energy use that varies depending on the time of day or year.
    • This is increasingly applied to commercial customers.
    • The rate is highest during times of peak demand, such as between 1 and 6 pm. It is lowest during periods of low demand such as 3 to 6 am.
    • If the rate varies by time of year, then summer rates might be highest, when air conditioning use is at its highest.
  • Demand Charge – the cost per kilowatt (kW) of power demand.
    • The charge applies to the highest demand that a customer had for power at any time during a month.
    • To help understand the concept, think of how fast an electric meter is spinning when a lot of equipment is turned on and the air conditioning is running at maximum load. This might be the situation for a short period of time, so energy use could be low, but the power demand could be very high for that short period.
    • It is typically based on the highest power draw seen in 15 minute increments during a month.

All of these components make building electric charges difficult to predict and budget for. Plus, unlike for gas, higher usage levels can dramatically increase the cost of that energy.

Most building professionals clearly understand the impact of the base electric rate or tariff and time of use rates. It is easy to appreciate that lowering air conditioning demand will reduce electric bills. However, those tariffs frequently represent 50% or less of a total electric bill with the demand charge being 50% or larger. By understanding the impact of air conditioning on demand charges, it can be seen that cool roofs have a large role to play impacting building energy efficiency.

Demand Charges

A simple way to think of demand charges versus energy use is to look at an electric meter:

How to read your meter

In a traditional residential meter shown on the left, the upper dials keep track of the cumulative energy use. The lower wheel shows the demand by how fast it is spinning. A more modern or small commercial meter shown on the right displays the same data in a digital fashion.

As an air conditioner does its work during a month, the energy use is added up, leading to an eventual charge based on kilowatt hours. But, on the hottest day of that month, during an afternoon period when the sun was at its highest and creating a higher thermal load through the roof and walls the air conditioner will be operating at a high load. Therefore its “demand” for power will spike and that spike will result in a charge per kW. Even if that spike is for just 15 minutes, that demand charge could be >50% of the monthly bill. Let’s look at a small office building to better understand this:

The customer has a 2 ton air conditioner that draws 7.2kW at maximum load. Each month it runs at an average 50% load for 10 hours a day with an electric charge of $0.090/kWh. That results in a monthly charge of 10 hours x 30 days x 7.2kW x 50% x $0.090/kWhr = $97.20

But, on a sunny day during that same month, the air conditioner might run at maximum load for 15 minutes, triggering a demand charge of $15.00 / kW. The resulting demand charge would be 7.2 kW x $15.00 / kW = $108.00

In this example the demand charge is larger than the use charge. Since dark roofs increase the need for air conditioning, they not only drive up monthly electricity consumption costs, they can significantly increase demand charges, as well.  A cool roof, on the other hand, reflects heat away and helps reduce both monthly consumption and demand charges.

Verdict

Not only is electricity more expensive than gas, but the rate structures are complex. Seemingly small increases in electricity use can result in large additional costs due to the compounding effects of time of use rates and demand charges.

Cool roofs lower a building’s energy use, thereby lowering operating costs. However, overall electric use is often only 50% of the electric charge and the maximum power draw and its demand charge can represent the other half. Cool roofs lower the internal temperature rise on hot sunny days and therefore lower the load on air conditioning equipment.

Location Doesn’t Matter!

As the following data indicates, it doesn’t matter where a building is located; if it uses air conditioning then converting to a cool roof will result in savings.

Let’s compare buildings in the northern, southern, eastern, and western U.S. The basic assumptions are:

Size: 100,000 sq.ft.
Electric use cost: $0.090 / kWhr.
Electric demand cost: $15.00 / kW
Gas cost: $0.80 / therm

To make the calculations conservative, we assumed a high insulation level of R-30, a heater efficiency of 80%, and an air conditioner coefficient of performance of 3.2. Using the Cool Roof Calculator tool, we estimated the impact of converting from a dark roof to a reflective membrane in the following locations:

Region City Savings
Southern USA Houston, TX $5,200 / yr
Northern USA Minneapolis, MN $2,600 / yr
Western USA San Francisco, CA $2,400 / yr
Eastern USA Raleigh, NC $4,100 / yr

Verdict

In warm and hot regions, cool roofs provide for larger energy savings, however, even in more moderate and even northern climates cool roofs improve a building’s energy efficiency. Modeling shows this to hold true so long as a building uses gas to heat and has air conditioning.

Will a Cool Roof Always Result in Actual Cost Savings?

There are a few reasons why some may not receive lower electric bills after converting to cool roofs. For example, overall electric costs may rise year over year or the utility rate structure could change. Also, changes in the building’s use, equipment, or operating patterns could increase overall lower consumption. Suffice to say, modeling shows that cool roofs reduce the impact of solar energy on a building and several case studies have demonstrated reduced utility bills. But, each building is unique and should be evaluated on its own terms.

Hot-Air Welding Under Changing Environmental Conditions


Hot-Air Welding Under Changing Environmental Conditions

The robotic welder’s speed, heat output and pressure should be properly programmed before the welding process begins. Photo: Leister.

Today’s most powerful hot-air welders for overlap welding of thermoplastic membranes are advertised to achieve speeds of up to 18 meters (59 feet) per minute. That’s fast enough to quickly ruin a roofing contractor’s day.

These robotic welders are digitally monitored to achieve consistent overlap welding performance, but they cannot adapt to changing environmental conditions automatically. It’s the contractor’s job to monitor and assess seam quality before the base seam is welded and when ambient temperatures or other factors potentially influence welding performance.

Successful hot-air welding requires the use of specialized, properly maintained and adjusted equipment operated by experienced personnel familiar with hot-air welding techniques. Achieving consistent welds is a function of ensuring that the roofing membrane surface is clean and prepared for heat welding, conducting test welds to determine proper equipment settings, and evaluating weld quality after welding has been completed.

Setting up hot-air robotic welders properly is the key to having a properly installed thermoplastic roof, and performing test welds is one of the most important steps. Making appropriate adjustments before the welding process begins ensures that the correct combination of welder speed, heat output and pressure is programmed into the robotic welder.

For most roofing professionals, these procedures have been firmly established in the minds of their crews and equipment operators through education and field training. But let’s not forget that Murphy’s Law often rules on both large and small low-slope roofing projects.

The frightening reality about using robotic welders is if they are set-up incorrectly or environmental conditions change, the applicator may weld thousands of feet of non-spec seam before anyone even bothers to check. If you probe for voids at the end of the day, it is probably too late.

If serious problems are discovered, the applicator must strip in a new weld via adhesive, cover tape, or heat welding, depending on what the membrane manufacturer will allow. If seams must be re-welded, the operator has to create not one, but two robotic welds on each side of the cover strip. The sheet will also need to be cleaned and re-conditioned no matter what method is used.

Can these errors be corrected? Absolutely. Except now the crew is in a real hurry because the roofer is working on his own time, and application errors tend to snowball under these conditions.

Reality Check

What goes on in the field is sometimes quite different than what one sees when hot-air welding thermoplastics under an expert’s supervision.To support this view, we asked four field service reps, each with a minimum of 35 years of roofing experience, to comment. The most senior “tech” has worked for six different thermoplastic membrane manufacturers in his career. Their names shall remain anonymous, but this writer will be happy to put readers in touch with them upon request.

Successful hand welding is a skill that is developed and refined over time. The correct selection of welder temperature and nozzle width can have a significant effect on the quality of the hand weld. Photo: GAF.

So, let’s welcome Christian, Dave, Mark and Walter, and get straight to the point: Is the average roofing crew diligent enough when it comes to properly testing welds using industry best practices?

“I would say ‘probably not,” exclaims Walter. Dave just shakes his head as his colleague Mark adds, “I would have to say no.”

Considering the generally laudable performance of thermoplastic membranes over the last decade or so, we must interpret our experts’ opinions as suggesting the need for further improvement in hot-air welding techniques. Hence, the purpose of this article.

“There are a few outstanding issues causing bad welds,” says Walter. “These include welding over dirty or contaminated membranes; improper equipment setup; using crews with inadequate training; and knowing the difference between the weldability of various manufacturers’ membranes.”

Welding equipment consists of three main components: the power supply, the hot air welder (either automatic or hand-held), and the extension cord. A stable power supply of adequate wattage and consistent voltage is critical to obtaining consistent hot air welds and to prevent damage to the welder.

The use of a contractor-supplied portable generator is recommended, although house-supplied power may be acceptable. Relying on power sources that are used for other equipment that cycle on and off is not recommended. Power surges and/or disruptions and insufficient power may also impact welding quality. Proper maintenance of welding equipment is also of obvious importance.

“Contractors seem to never have enough power on the roof,” observes Mark. “The more consistent your power is, the more consistent your welds will be. Too many times, I’ve seen too many tools (hand guns, auto welder, screw guns and a RhinoBond machine) plugged into one generator.”

Generator-induced challenges on the jobsite are going to arise, agrees Christian. “But at least today there is more experience in understanding, dealing with, and ultimately preventing these issues,” he says.

Most TPO and PVC membrane suppliers also recommend using the latest automatic welding equipment, which provides improved control of speed, temperature and pressure. Our four experts generally agree that field welding performance has improved over the years and programmable robotic welders have helped. They also point to proper training and experience as crucial factors.

Planning and Teamwork Are Essential in Tackling Retail Project


Planning and Teamwork Are Essential in Tackling Retail Project

Peach State installed a mechanically attached TPO system over the existing modified bitumen roof system on two buildings totaling approximately 75,400 square feet.

Peach State installed a mechanically attached TPO system over the existing modified bitumen roof system on two buildings totaling approximately 75,400 square feet.

Headquartered in Atlanta, Peach State Roofing Inc. has 15 branches and covers clients across the nation. The company specializes in commercial and industrial roofing, and excels at large-scale single-ply jobs. The goal of every branch is to provide the same level of service for clients no matter where they are in the country, as exemplified by a recent project at a large retail mall in South Carolina.

Peach State’s Charlotte branch is located in Rock Hill, S.C. The company has re-roofed three of the five roofs at Gaffney Premium Outlets in Gaffney, S.C., including two roofs completed this year in just two weeks. Anthony Wilkerson, the branch manager, and Blake Wideman, strategic accounts, shared their insights on the project.

Peach State’s Charlotte branch focuses primarily on re-roofing, service and maintenance work for existing customers and property managers. Most of the company’s work involves TPO, EPDM and PVC, but crews have to be able to handle almost every type of system on the market. “If there is a hotel with some shingles or metal on it, we want to be able to complete every facet of the job, but most of our work revolves around single-ply roofing,” Wilkerson states. “We are certified with every major single-ply manufacturer.”

According to Wilkerson and Wideman, Peach State’s strength lies in building relationships with its clients by providing quality workmanship and excellent customer service. “We do that through our project management, our expertise and our training,” says Wilkerson. “We put a lot into training our employees so that they know how to do the technical details that the manufacturers are asking for.”

Wilkerson believes Peach State offers the best of both worlds—flexibility at each branch and the depth of knowledge from the large corporate organization. “We’re independent, but I work with the corporate office every day,” says Wilkerson. “We have local representation around the country, but at the same time we have that teamwork, so you’re still getting the same quality from each office that you’re getting from the corporate office. We try to be as close to the way Atlanta does things—the Peach State Way—all across board, all over the country.”

Landing a Big One

In the case of the recent project at Gaffney Premium Outlets, the work was an outgrowth of the company’s previous successful projects, including a re-roofing job at the same complex last year. “Our bid was what they were looking for,” Wideman says. “We gave them the price they were looking for and the quality they wanted. That’s how we were awarded this project.”

This aerial view shows the five buildings of the Gaffney Premium Outlets mall. Peach State Roofing re-roofed the two buildings on the left this year, after completing work on the building at the far right last year.

This aerial view shows the five buildings of the Gaffney Premium Outlets mall. Peach State Roofing re-roofed the two buildings on the left this year, after completing work on the building at the far right last year.

The mall is made up of five buildings, and the company re-roofed two this year totaling approximately 75,400 square feet. Peach State installed a mechanically attached TPO system from Firestone over the existing modified bitumen roof system. “We came up with a plan to cover the old roof with a half-inch high-density cover board,” Wilkerson says. “Then we mechanically attached a Firestone 60-mil white TPO system over the cover board.”

The system was chosen for its durability, according to Wilkerson. “They were looking for a long-term solution,” he says. “We went with a re-cover because it was more cost-effective for their budget, but we could still offer them the same warranty and the same guarantee that the system would be just as effective if they had torn the old system off and started from scratch.”

The company used 8-foot rolls of TPO on the project for several reasons. “We went with 8-foot rolls on this project because it was easier to apply the rolls,” notes Wilkerson. “They are not as heavy as the 10-foot rolls. It’s easier to let the rolls relax when you roll them out and easier to keep them tight when you are securing them to the deck.”

Fasteners were installed every 12 inches on center at the edge of the TPO sheets, and the next sheet was heat welded over the top of the screws and plates, and then mechanically fastened at the other end.
Extra care had to be taken with the details, especially walls and curbs. “We tore all of the old membrane off the curbs and off the walls, and we used bonding adhesive to go up the walls,” Wilkerson explains.

At the walls, the field sheets were run up the wall 12 inches and mechanically attached. “We adhere a sheet to the wall, and we heat weld that to the field sheet,” explains Wilkerson, “At the top of that, we use a water cutoff behind the sheet, and we use a termination bar. The termination bar is installed 12 inches on center, and then we use a sealant at the top of the termination bar. We came back with a surface-mount counterflashing, which basically just goes over the top of the termination bar. It has a little kick-out on it, so once that’s attached, it gives you double protection where your membrane is terminated.”

Curbs were handled in a similar fashion. “With the curbs, you run the field sheet right up to the curb, and then you mechanically attach it 12 inches on center,” Wilkerson notes. “Then we use bonding adhesive to install a piece of membrane on each side of the curb. We don’t do one piece and wrap it all the way around. We use four separate pieces, and we adhere them to the curb. Then we heat weld those pieces to the field sheet. For the curbs, we use a flashing that goes underneath the curb itself, and we attach that 12 inches on center all the way around. That lets the water shed over the HVAC unit and then down onto the membrane past the flashing, so there’s nowhere for the water to penetrate.”

Meeting the Challenges

The sheer size of the project was a challenge, but Peach State is used to handling large-scale projects. Logistics and scheduling were also demanding due to customer activity at the mall. “It was a good project for us, but I’d say one of the biggest challenges was that the mall remained open the whole time we were doing the roof,” Wilkerson says. “We had to check in with each tenant in every building to make sure everything was OK from the night before.”

The project called for roofing specific sections each day to make sure the roof stayed watertight at all times. “We sealed the roof up every night 100 percent, so if it rained in the evening, it had to be like we had never been up there,” Wilkerson recalls. “If we took three air conditioners apart in a section that we did one day, at night before those guys went home the air conditioners were wrapped back up, the flashing was put back around the air conditioner and all of the edges of the roof were sealed to the old roof so everything was watertight.”

Safety was also a concern, especially with pedestrian traffic below. “We had to make sure all of our safety procedures were in place for our crews and for the members of the public going in and out of the doors,” Wilkerson says.

The crews used safety lines at the perimeter, and anyone outside the safety lines had to be tied off at all times. “We had to make sure we had a man strictly watching out for the safety of the crews. You have to make sure any little pieces of membrane don’t blow off the roof. You have to make sure all of that is being cleaned up steadily as the job is going on. You don’t want the public to see anything except the flag stands on the roof.”

Staging was complicated, but luckily the jobsite offered ample space for trucks and cranes to be moved between the buildings. The key was to tackle high-traffic areas early in the morning and move to less busy spots as the day wore on.

Proper staging is crucial to jobsite efficiency, notes Wilkerson. “We like to stage the material as we put it on so we’re not dragging it across the roof,” he says. “It’s all right there for them, laid out as they go.”

Support and teamwork are essential up and down the line. “We work really well as a team, so if anyone has any small questions, they can ask the superintendent and call me, so we can make sure we take care of it the Peach State Way.”

Flexing Their Muscles

The project went off without a hitch, says Wilkerson. The mall traffic was never disrupted. “Not one leak, not one complaint on this project,” he says. “Our project management on this project was spot on. Our superintendents held their own out there. And our guys—it’s the attention to quality and all the time we put into training our guys that allows them to do this and make it look almost seamless. It’s one of those situations where you want it to look easy while you’re doing it, but when you’re in the mix of it and you’re trying to get it all done, it’s not as easy as it looks.”

Customer service was crucial. It wasn’t just the property management company that had to be kept informed—it was each individual retailer in the building. “There were so many people to deal with,” notes Wideman. “Every manager of each of those units had to be kept informed of the process. Roofing is not as hard as people think, but keeping up with the owners, keeping people happy, letting people know ahead of time what’s going on is a big challenge. We had to make friends with everyone ahead of time and let them know where to call with any questions.”

“The project, as far as roofing goes, was pretty straightforward,” concludes Wilkerson. “The key is to keep up with everyone on a daily basis and let them know what’s going on so if there is a small problem, it doesn’t keep brewing until it’s a big problem.”

Definition of Resilience: Hospital Provides a Lesson in Preparing for Weather Events


Definition of Resilience: Hospital Provides a Lesson in Preparing for Weather Events

Staten Island University Hospital escaped major damage during Hurricane Sandy. The city of New York allocated $28 million to fund the hospital’s resiliency plan, and the state contributed an additional $12 million.

Staten Island University Hospital escaped major damage during Hurricane Sandy. The city of New York allocated $28 million to fund the hospital’s resiliency plan, and the state contributed an additional $12 million.

Almost five years ago, Hurricane Sandy bore down on New York City with winds that reached gusts of 100 miles an hour and a storm surge 16 feet above normal that flooded huge parts of the city. Entire neighborhoods lost electricity for several days, the Stock Exchange closed during and immediately after the storm, and scuba divers were called in to assess damage in parts of the city’s submerged subway system.

Staten Island, one of New York’s five boroughs, was heavily damaged. Its position in New York Harbor, at the intersection of the coastlines of Long Island and New Jersey, leaves the island particularly exposed to storm surge during extreme weather events. A geologist from Woods Hole Oceanographic Institution in Massachusetts described Staten Island as being, “at the end of, basically, a big funnel between New Jersey and New York.”

Staten Island University Hospital almost miraculously escaped major damage, despite flood waters coming within inches of it doors. The hospital stayed open during and after Hurricane Sandy, continuing to provide vital services despite the storm. The hospital is home to the largest emergency room on Staten Island, and houses more than one third of the borough’s in-patient beds. New York Mayor DeBlasio has called the hospital, “a truly decisive healthcare facility—even more so in times of crisis.”

While both hospital and city officials were relieved that the facility had escaped Sandy largely unharmed, the lesson that Sandy delivered was taken to heart: major mitigation efforts were needed if the hospital expected to survive similar storms in the future. With this in mind, the city of New York allocated $28 million to fund the hospital’s resiliency plan, with the state kicking in an additional $12 million.

The money is being spent on three major projects to better prepare the hospital for future storms: the elevation of critical building power and mechanical systems, the installation of sanitary holding tanks and backflow prevention, and the installation of major wind resiliency and roofing improvements. 

Resilient Design

The Staten Island experience, and the plan to upgrade its ability to withstand major weather events, is hardly unique. Nationwide, resilient design has become a major focus of the construction community.

Hurricane Sandy certainly intensified the sense of urgency surrounding the need for resilience. But well before that, Hurricane Katrina, in 2005, provided a tragic case study on the fragility of seemingly stable structures, as the storm brought a small, poor southern city to the brink of chaos and devastated entire neighborhoods. While these two hurricanes drew national and international attention, communities throughout the country have also been dealing with frequent, erratic and intense weather events that disrupted daily life, resulting in economic losses and, all too often, the loss of human life. These emergencies may include catastrophic natural disasters, such as hurricanes, earthquakes, sinkholes, fires, floods, tornadoes, hailstorms, and volcanic activity. They also refer to man-made events such as acts of terrorism, release of radioactive materials or other toxic waste, wildfires and hazardous material spills.

The focus, to a certain degree, is on upgrading structures that have been damaged in natural disasters. But even more, architects and building owners are focusing on building resilience into the fabric of a structure to mitigate the impact of future devastating weather events. And, as with the Staten Island Hospital, the roof is getting new attention as an important component of a truly resilient structure.

The resilience of the roofing system is a critical component in helping a building withstand a storm and rebound quickly. In addition, a robust roofing system can help maintain a habitable temperature in a building in case of loss of power. Photo: Hutchinson Design Group.

So, what is resilience, how is it defined, and why is it important to buildings in differing climates facing unique weather events? The Department of Homeland Security defines resilience as “the ability to adapt to changing conditions and withstand and rapidly recover from disruption due to emergencies.” The key words here are “adapt” and “rapidly recover.” In other words, resilience is measured in a structure’s ability to quickly return to normal after a damaging event. And the resilience of the roofing system, an essential element in protecting the integrity of a building, is a critical component in rebounding quickly. In addition, a robust roofing system can provide a critical evacuation path in an emergency, and can help maintain a habitable temperature in a building in case of loss of power.

According to a Resilience Task Force convened by the EPDM Roofing Association (ERA), two factors determine the resiliency of a roofing system: durable components and a robust design. Durable components are characterized by:
Outstanding weathering characteristics in all climates (UV resistance, and the ability to withstand extreme heat and cold).

  • Ease of maintenance and repair.
  • Excellent impact resistance.
  • Ability to withstand moderate movement cycles without fatigue.
  • Good fire resistance (low combustibility) and basic chemical resistance.
  • A robust design that will enhance the resiliency of a roofing system should incorporate:

  • Redundancy in the form of a backup system and/or waterproofing layer.
  • The ability to resist extreme weather events, climate change or change in building use.
  • Excellent wind uplift resistance, but most importantly multiple cycling to the limits of its adhesion.
  • Easily repaired with common tools and readily accessible materials.
  • More Information on Resilient Roofing

    The Resilience Task Force, working with the ERA staff, is also responding to the heightened interest in and concern over the resilience of the built environment by launching EpdmTheResilientRoof.org. The new website adds context to the information about EPDM products by providing a clearinghouse of sources about resilience, as well as an up-to-date roster of recent articles, blog posts, statements of professional organizations and other pertinent information about resilience.

    “This new website takes our commitment to the construction industry and to our customers to a new level. Our mission is to provide up-to-date science-based information about our products. Resilience is an emerging need, and we want to be the go-to source for architects, specifiers, building owners and contractors who want to ensure that their construction can withstand extreme events,” said Mike DuCharme, Chairman of ERA.

    EPDM and Resiliency

    The Resilience Task Force also conducted extensive fact finding to itemize the specific attributes of EPDM membrane that make it a uniquely valuable component of a resilient of a roofing system:

  • EPDM is a thermoset material with an inherit ability to recover and return to its original shape and performance after a severe weather event.
  • EPDM has been used in numerous projects in various geographic areas from the hottest climate in the Middle East to the freezing temperatures in Antarctica and Siberia.
  • After decades of exposures to extreme environmental conditions, EPDM membrane continues to exhibit a great ability to retain the physical properties and performances of ASTM specification standards.
  • EPDM is the only commercially available membrane that performs in an unreinforced state, making it very forgiving to large amounts of movement without damage and potentially more cycles before fatiguing.
  • EPDM offers excellent impact resistance to hail, particularly when aged.
  • EPDM is resistant to extreme UV exposure and heat.
  • EPDM far exceeded the test protocol ASTM D573 which requires materials to pass four weeks at 240 degrees Fahrenheit. EPDM black or white membranes passed 68 weeks at these high temperatures.
  • Exposed EPDM roof systems have been in service now for 50-plus years with little or no surface degradation.
  • EPDM is versatile.
  • EPDM can be configured in many roofing assemblies, including below-grade and between-slab applications.
  • EPDM is compatible with a broad range of construction materials/interfaces/conditions, making it a good choice for areas that may encounter unique challenges.
  • EPDM can be exposed to moisture and intense sunlight or totally immersed in salty water.
  • EPDM can easily be installed, repaired and restored following simple procedures without the use of sophisticated, complicated equipment.
  • EPDM can be repaired during power outages.

    Re-Roofing of Shopping Center Covers Over 75,000 Square Feet


    Re-Roofing of Shopping Center Covers Over 75,000 Square Feet

    Southgate Shopping Center: Sebring, Florida

    Roofing contractors often find themselves tackling re-roofs at shopping centers in piece-meal fashion, doing sections over the years as the budget allows. When property manager Southern Management and Development decided to remodel the entire Southgate Shopping Center in Sebring, Fla., in conjunction with Publix Markets’ replacement of their existing store at the location, they looked to Advanced Roofing to get the job done.

    The scope of work included re-roofing three large sections of the retail plaza and a drugstore on the property. The roofing portions totaled 79,556 square feet.

    Roof System

    The roof specified was a two-ply modified bitumen system from Johns Manville. In the three large sections of the plaza, the existing built-up roof was completely torn off, while the drugstore was a re-cover project, notes Andrew Vik, estimator and project manager with Advanced Roofing’s Tampa branch, which operates under branch manager Michael Landolfi.

    Roofing work started in November 2016 and was completed in February 2017. After the existing roof was removed, crews installed 2-inch polyiso to the steel deck. “We mechanically fastened that with a half-inch USG SecuRock cover board through the steel deck,” notes Vik. “The two plies of modified bitumen were then torch applied, a smooth base sheet and a white granulated cap sheet.”

    On the drugstore, the roof was vacuumed, and the cover board and two plies were installed over the top of the old roof system.

    In addition to the roofing scope, Advanced Roofing’s HVAC division installed and removed heating and air conditioning units and replaced some obstructive ductwork. “We had our own HVAC people working with our roofing crews, so it was easy to coordinate everything,” notes Vik. “We had HVAC installations on three of the buildings, and we remounted existing units on two of the buildings. There was also a lot of demolition on the south building, as there were several derelict units that
    had been sitting there for quite some time. Those had to be hoisted off there and taken out.”

    A Challenging Project

    Logistics are often a challenge with a shopping center that remains open to the public, notes Vik. “You have to load and unload multiple levels of the roof at different times,” he says. “Customer relations is also a challenge; you have to keep everyone happy and ask a lot of questions. The construction manager has to do a lot of P.R. when he’s there.”

    Demolition portions of the project were done at night and application during the day, so business at the mall was never disrupted. Traffic in the parking area was also a key concern.

    “Setup areas had to be barricaded and marked off while we were loading and unloading,” Vik says. “There was even a drive under bridge connecting two buildings that had to be re-roofed, so we always had to be mindful of people below.”

    Parapet walls did not surround all portions of the roof, so safety precautions included a safety perimeter; employees outside the perimeter had to be harnessed and tied off to a portable fall protection anchor system by Raptor.

    The project went off without a hitch, according to Vik. “The mall was 100 percent open during the entire project,” he says. “Things went very smoothly— especially for everything that was involved. One of our mottoes is, ‘The harder the job, the better.’ We like a challenge. We take on a lot of projects other companies shy away from.”

    The keys to his company’s success are coordination and versatility, states Vik. “We do it all,” he says. “We didn’t have to get anybody from outside the company to work on the project. We did all the roofing, all of the HVAC, and all of the hoisting was done in-house. We’ve also got lightning protection inhouse, and we have a solar division. We have a great team. Everyone does their part to get the bids out and get the jobs done. It’s the best team I’ve ever worked with.”

    Until now, there has been surprisingly little research into the overall thermal impact of the fasteners that penetrate roofing insulation. A recent study shows that even relatively conservative use of fasteners creates enough thermal bridging between the roof deck and the insulation to substantially reduce the overall thermal performance of the building envelope.

    Guest blogger Eric K. Olson, P.E. explains his research (Olson, Saldanha, and Hsu, “Thermal Performance Evaluation of Roofing Details to Improve Thermal Efficiency and Condensation Resistance,” ASTM Roofing Research and Systems and Standards Development, Vol 8, STP 1590, ASTM International, November 2015)

    Introduction

    Thermal insulation in roofing systems plays a substantial role in the overall thermal performance of the building envelope.  Energy code requirements for the R-value of the roofing insulation are becoming ever more stringent, requiring increased insulation thickness. Mechanical fasteners are commonly used to secure the insulation and roofing membrane to the structural roof deck.

    Each metal fastener creates a thermal bridge that reduces the effectiveness of the insulation.  For a single fastener, the impact would probably be negligible. A typical roof, though, may include thousands of fasteners. The effect of these myriad thermal bridges adds up. That is, the combined impact of the fasteners can substantially reduce thermal performance.

    Considering the potential impact involved, there is surprisingly little information in the roofing industry regarding the overall thermal impact of fasteners on roofing insulation. To explore and help quantify these thermal impacts, some colleagues and I decided to perform and publish the results of three-dimensional computer heat flow models of fasteners and other roofing details that penetrate the roofing insulation (Olson, Saldanha, and Hsu, “Thermal Performance Evaluation of Roofing Details to Improve Thermal Efficiency and Condensation Resistance,” ASTM Roofing Research and Systems and Standards Development, Vol 8, STP 1590, ASTM International, November 2015).

    Modeling and Analysis

    We modeled a roofing system with 4 in. of polyisocyanurate insulation and 1/2 in. gypsum cover board with a nominal R-value of R-27.0, over steel deck, with the insulation fastened using steel plates and #14 roofing screws with a diameter of 0.214 in.

    Modeling one fastener with plate penetrating a one sq. ft. area of insulation (e.g., sixteen fasteners per 4 ft. by 4 ft. insulation board), we found the following:

    1. Case 1: With the steel plate above the gypsum cover board, the fastener and plate drop the R-value from R-27.0 to R-19.2 (a 29% reduction in R-value).
    2. Case 2: Placing the plate beneath adhered gypsum cover board provides little improvement due to poor thermal resistance of the gypsum, raising the R-value from R-19.2 to R-19.5.

    Swapping out the gypsum cover board with 1/2 in. high-density polyisocyanurate cover board raises the nominal R-value of the system from R-27.0 to R-29.0.  Repeating the above analysis, we found the following:

    1. Case 3: With the steel plate above the polyisocyanurate cover board, the fastener and plate drop the R-value from R-29.0 to R-21.2. This is a 27% reduction in R-value as compared to the nominal R-value using polyisocyanurate cover board.
    2. Case 4: Placing the plate beneath adhered high-density polyisocyanurate cover board raises the R-value from R-21.2 to R-23.8. This is a 9% improvement as compared to the case with the plate on top of the polyisocyanurate cover board, but still an 18% reduction as compared to the nominal R-value using polyisocyanurate cover board.

    The above cases represent high rates of fastening (one per sq. ft.) that may be encountered at corners or perimeter zones.  In practice, field-of-roof zones require fewer fasteners and have greater area, and thus have a greater influence on thermal performance than corner and perimeter zones.  The figure below graphs the effective R-value versus the number of evenly spaced #12 fasteners and steel plates per 4 ft. x 4 ft. insulation board, using the conditions of Case 1 (fasteners through and plates above gypsum cover board) above.

    Change in effective R-value Relative to Number of Fasteners for Case 1

    Effective R Value

    As can be seen above, the thermal bridging created by even light fastening rates can be significant.  A pattern of five fasteners per board, frequently seen in field areas of a roof, drops the effective R-value to R-24.  This is an 11% reduction in R-value.

    Our work to date indicates that mechanically fastening roofing insulation substantially reduces the roof’s thermal performance as compared to a similar system without fasteners. More work remains to be done to quantify thermal bridging through roofing systems. The influence of fastener diameter, the use of less conductive fasteners (like stainless steel), and the use of polymer plates in reducing thermal bridging should be explored.

    A better understanding of these thermally bridging elements will help identify options to help mitigate their effect. This, in turn, will help designers to better specify the thermal performance characteristics of their roofing systems.
