Mark Andol is the owner and founder of General Welding and Fabricating, with locations in Elma and Rochester, N.Y. That business, which manufactured structural and decorative steel components for this store, has been operating since 1989. When the recession hit almost 10 years ago, Andol lost much of his business to companies located overseas, forcing him to cut his workforce to half its size. At that point, he began envisioning a store that would only carry products that are 100 percent American made, to help grow manufacturing within the United States. Andol’s vision became a reality in 2010 when he opened the doors to the first Made in America store in Elma.

Roof Report

The mission of the Made in America Store is to create and save jobs in the United States by increasing American manufacturing. By installing ATAS’ Dutch Seam metal roofing panels, which are made in America, on this new flagship store, it only further reinforced this mission. Dutch Seam, a continuous standing seam metal roof panel, features an integral lock and seam which prevents “blow-off” or “creeping” of the seam. It also eliminates the need for separate seam caps and field seaming.

When ATAS International announced the company’s 2016 Project of the Year winners at an awards banquet on May 8, the Made In America flagship store project took first place in the commercial roofs category.

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.

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.”

Extra care had to be taken with the details at walls and curbs. Bonding adhesive was used to install a piece of membrane on each side of the curb. Then those pieces were heat welded to the field sheet.

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.

    Engage With Potential Customers on the Social Media Platform They Use Most


    Engage With Potential Customers on the Social Media Platform They Use Most

    Social media can be an exciting territory for contractors looking to promote their businesses in a relatively inexpensive, but impactful, way. But it can be equally overwhelming with the abundance of social platforms available, as well as the nuances involved for marketing on each one.

    If you’re new to marketing your business socially, Facebook is a great place to start. It’s an easy-to-use platform that provides several features for connecting with potential customers locally and nationally. Or, if your business is already active on the platform but not seeing much return, there are simple ways to begin improving your activity today.

    Read on to learn simple tips and advice on how to effectively promote your roofing business on Facebook.

    Why Focus on Facebook?

    It’s important to note why it is relevant to establish and maintain a presence for your business on Facebook.

    First and foremost, your customers are already active on the platform. Facebook continues to be the most popular social media platform, as cited by the Pew Research Center, where 79 percent of online adults have a profile. In fact, the number of Facebook users is more than double the number of people who use other social platforms, such as Instagram (32 percent), LinkedIn (29 percent), Twitter (24 percent) or Pinterest (31 percent).

    Plus, establishing and maintaining a Facebook page can also be beneficial in driving visitors to your website. In fact, search engines tend to reward businesses with a strong social following through higher organic rankings. In other words, the more people who are engaged with your company on Facebook, the better odds your business will show up sooner in a potential customer’s search results for a local roofing contractor.

    Further, the platform is also a great way to create a sense of connection with your internal team. For instance, Facebook can be used to showcase your company culture, share news and engage with your own employees—especially if you’re a large contractor with multiple locations.

    Useful Strategies to Grow Your Page

    Profile setup: Building a solid foundation of followers begins with setting up your profile correctly. Be sure to set up a Business Page instead of a personal Facebook page. This way, current and future customers can “like” your page, or become a fan, and keep up-to-date on the latest news from your company.

    Also, it’s important to have a profile image and cover art (the large image at the top of the page), as well as complete details about your business on the “About” page, including a description of your business, location, contact information, services offered, hours, website and more.

    Tip:

    If you already have an existing account that was set up as a personal profile, you can convert it into a business page at facebook.com/business.

    Content sharing: Once your page is set up, it’s time to start sharing content. Begin with one or two posts per week, and then gradually start increasing your posting schedule as you gain a more established following.
    Think of Facebook as an extension of your website to tell customers more about your business in an inviting and personal, but still professional, atmosphere.

    Looking for content ideas? Think about sharing your knowledge and expertise: your project work! Take before-and-after photos of projects that showcase a new roof installation or repair. Or if it’s a long-term project, document it each day with photos or videos that explain the installation process you’re undergoing, the products you’re using and more. Make sure you have your customer’s consent before posting details or pictures about any project.

    Also, do you have a company blog on your website? If so, share out individual posts with a “teaser” on the details the article contains, along with a link back to the specific post. This helps to establish your credibility as a knowledgeable professional, but can also help to drive potential customers back to your website to learn more. If you’re still working to set up your company blog, another option is to publish a “Note” from the left sidebar of your Facebook business page. This long-form Facebook post is a great alternative while you work toward setting up your blog online.

    You can also consider sharing links to blog posts from a manufacturer whose products you use. They often provide helpful blog articles with tips and advice for both contractors and homeowners—so you may even find something of value to you in the process!

    Lastly, you can use your page as a way to share positive customer testimonials in the form of photos and videos. Again, it’s important to ensure you first have your customer’s consent before sharing their testimonials. Be sure to also encourage your satisfied customers to submit their own Facebook reviews for a job well done. These reviews allow them to share their experiences and rate your performance directly on your Facebook page, which can help facilitate future business and leads.

    Tip:

    Facebook can also be used as a means to share company promotions, special holiday or seasonal incentives, and events you may be hosting or attending.

    Page promotion: As you start to proactively post useful content, you’ll begin to establish a following on your page. However, there are also several paid promotion tactics you can use to increase your page’s reach and engagement.
    One popular paid tactic is a pay-per-click (PPC) campaign, which is a form of advertising where you pay a set amount each time someone clicks on an ad you’ve produced. Determine what you would ultimately like users to do, and create a post or simple ad that prompts them to take that action. For example, you can drive homeowners to visit your company website, provide their contact information for a free quote, like your Facebook page, download a coupon and more.

    If you have a particularly interesting post that has been performing well on your page (maybe it has received a lot of positive comments, for example) and you’d like it to reach even more people, consider “boosting” or sponsoring that post. This means putting a set amount of money behind promoting a post, say $100, to expand its reach. Geo-targeting, or selecting a specific audience and geography you’d like to reach, helps amplify your message to the right people—your targeted customers.

    Tip:

    Avoid using text in your images for paid posts or campaigns. Facebook guidelines reduce the reach of these images as the system considers them too “spammy” or ad-centric and cluttered. In many cases, image text could prevent your promotion from running entirely.

    Innovative Roofing Insulation Appeals to Owners, Architects


    Innovative Roofing Insulation Appeals to Owners, Architects

    Because Rich-E-Board roofing insulation is light and easy to install, it lowers the cost of delivery and handling and can reduce labor costs by more than half.

    Because Rich-E-Board roofing insulation is light and easy to install, it lowers the cost of delivery and handling and can reduce labor costs by more than half.

    It’s exceptionally thin and easy to install. It delivers an R-value of 50 to commercial, industrial and government buildings. Now, Rich-E-Board, the innovative new roofing insulation, is enjoying a groundswell of interest from building
    owners, contractors and architects seeking to drive down construction costs and boost energy efficiency.

    Rich-E-Board recently received a patent for its proprietary Vacuum Insulated Panel—two polymeric foam cover boards that sandwich the panel—and the adhesive ribbons that bind the boards and panel together. This ultra-thin insulation offers a certified alternative to a huge commercial roofing market—billions of square feet in construction every year—challenged with
    meeting stringent standards for energy efficiency.

    While conventional insulation requires a thickness of 15 inches to reach an R-value of 50, Rich-E-Board achieves the same result at just 1.5 inches thick. Rich-E-Board can be installed on most roof deck types, including ballasted roof systems, and can support all conventional low-slope roof systems.

    Rich-E-Board’s design delivers significant advantages:

    • Lower energy bills: Achieving an R-value of 50 can cut a building’s heating and cooling costs by 8 to 10 percent, according to the GSA.
    • Simpler retrofits: Rich-E-Board enables retrofitted structures to achieve required R-values in less time, with fewer materials, and without costly and destructive building modifications.
    • Reduced construction costs: Because Rich-E-Board is light and easy to install, it lowers the cost of delivery and handling and can reduce labor costs by more than half.
    • Design flexibility: With its slim profile— especially compared with multi-layer insulation— Rich-E-Board saves space, expanding the design options for architects.

    Rich-E-Board is also fireproof and water and mold resistant, notes Joanne Collins, president and CEO of R-50 Systems, maker of Rich-EBoard. “Our team focused on creating a game-changing alternative,” Collins says. “Rich-E-Board fills a significant
    void in the marketplace by providing an insulation system capable of meeting today’s tougher energy standards.”

    Success in the Field

    Rich-E-Board has made a successful transition from the drawing board to the marketplace. Owners and architects have taken advantage of the insulation’s slim profile and high R-value on several building projects.

    At a government building in Chicago, for example, owners chose to install 3,600 square-feet of Rich-E-Board as part of a roof retrofit aimed at lowering lifetime energy costs. Rich-E-Board’s slim profile also cut construction costs by more than $20,000 by streamlining design and installation.

    At the Cohen Courthouse in Camden, N.J., Rich-E-Board was selected for the roof retrofit, eliminating the need for expensive building modifications that would have been required for conventional insulation. The decision lowered the project cost by $200,000.

    Earlier this year, Rich-E-Board was awarded a patent for its design. More recently, the insulation earned its first LEED 4 designation.

    “We’re seeing a huge increase in Rich-E-Board as the roofing market learns more about the benefits it brings to the commercial roofing,” Collins says. “This product fills a significant void by providing an insulation system capable
    of meeting today’s tougher energy standards.”

    Collins notes that, in addition to the $5 billion annual market for commercial roofing, Rich-E-Board can be used in walls and other building applications. Rich-E-Board is 99 percent recyclable and made entirely in the U.S.
