Algae Resistant Roofing System Roofing Shingles


The Copper Principle

 

The idea behind algae immune roof tiles is in fact quite simple. Copper, which is a cornerstone in this brand-new innovation of shingles, quits algae before it affixes to your residence. House owners can now acquire roof shingles that have actually copper built directly right into the tinted granules. The copper isn’t visible, but it’s existence is absolutely really felt by unsuspecting algae as it is incapable to survive on your roof covering’s surface area. With use of these new products, your entire roofing system ends up being an inhospitable host to algae. Expectedly, these roof shingles will set you back a few additional dollars, but are well worth the extra price when you factor the expense of algae elimination. The copper or zinc present in algae immune tiles are triggered further by rainfall, which distributes the algae fighting parts even further along the roofing’s surface area. Rainfall usually promotes wetness on the roof, which works as a breeding ground for algae. The good news is, that’s no more the case thanks to algae resistant roofing tiles.

 

Numerous homeowners are strained with undesirable residence guests annually. It’s not the sort of visitors that you’re considering, nevertheless, as this guest does not get in the home. It invites itself to rest on your roofing system and also triggers unpleasant staining. It’s algae and it impacts a great deal of property owners, specifically those that stay in areas of high moisture. Algae, however, doesn’t discriminate against those who don’t reside in very humid environments. It will certainly affix to any kind of roofing as well as can be carried through wind, squirrels, birds, and so on

 

Producers Of Algae Resistant Roofing Tiles

 

Much of today’s top shingle makers offer algae resistant roof covering tiles, which can be mounted by a neighborhood roofer. They have accessibility to a variety of products, consisting of roof shingles with attractive shades to compliment your house. A roofing contractor typically gets a discount on these products as well as, then, might have the ability to pass that cost savings onto the client. In most cases, warranties are even supplied to cover algae immune shingles. Constantly choose a firm that supports their product.

 

Finding A Specialist

 

A specialist roofing contractor in your location will certainly be able to order, as well as install, your selection of algae immune roofing system shingles. After finding the perfect service provider, ask them for a quote as well as an anticipated duration. It may be a good idea to get several quotes from various contractors prior to making a decision. Recognizing that your roof is protected, from undesirable algae, will certainly give you a greater satisfaction and also enable your home to continue to be beautiful and fungus-free.

Copper Is the Solution for Challenging Residential Roof Restoration


Copper Is the Solution for Challenging Residential Roof Restoration

“We like the tough jobs,” says Dean Jagusch, president and owner of Wagner Roofing Company. “We like the intricate jobs.”

Headquartered in Hyattsville, Md., Wagner Roofing has served the Washington area market for more than a century. “We specialize in historic restoration and innovative architectural roofing and sheet metal,” Jagusch notes. “We’re full service. We do slate, copper, tile, and have a low-slope commercial division as well. But our trophy stuff tends to be of the steep-slope variety.”

A recent residential restoration project in Alexandria, Va., certainly qualifies as “trophy stuff,” taking home a North American Copper in Architecture Award from the Copper Development Association (CDA) in the “Restoration: Roof and Wall” category.

It’s easy to see why. The origami-inspired design features multiple roof angles, but the daring design was problematic. Even though the home was relatively new, the owners were plagued by leaks. Along with Restoration Engineering Inc. of Fairfax, Va., Wagner Roofing was called in to consult on the project, determine the source of the leaks, and come up with a solution.

The original galvalume standing seam roof channeled the water into a large, stainless steel internal gutter with roof drains. Jagusch found that the leaks were occurring at two types of critical points. First, there were leaks where the internal roof drains met the central gutter. The other problem spots were along the pitch transitions.

Jagusch felt that installing a conventional-style painted galvalume roofing system in those spots was almost impossible. “We felt that was since it was an area that was failing, we wanted a metal we could work with when we met a transition and turn the panels vertical where we needed to without having to break them and rely on rivets and caulk,” he says.

Custom five-sided downspouts were fabricated

Copper was the answer. “The detailing was pretty tough to do, so we recommended changing it to copper so we could work with it, be able to solder and have a more seamless roofing assembly,” Jagusch recalls.

Another key to the project was redesigning how the roof drained. “We decided to push all the water to the exterior,” he says. “We collaborated with Restoration Engineering and we fleshed out the original redesign.”

The team decided that installing a copper roof system with a new drainage plan would be the best way to eliminate the leaks and keep the inspiring look the homeowners desired.

“We wanted to eliminate the drains and push all the water to the exterior, so that’s why we went for the re-slope of the big central gutter,” Jagusch says. “Also, at the transitions, we wanted to make sure we were 100 percent watertight, so we used a combination of turning up panels and soldered cleats to get everything into place.”

Solving the Puzzle

With its intersecting planes, the roof made laying out the panels an intricate puzzle. “You also had large expanses of roofing that changed pitch throughout,” Jagusch explains. “Panels had to be laid correctly because not only does the roof slope up, but it also slopes sideways. The layout of the panels was critical from the get-go. We all looked at it and agreed that we would follow parallel to the actual trusses, which we felt was the best solution.”

The old roof system was removed and stripped down to the 3/4–inch plywood deck. “We covered the entire roof deck with Grace Ultra,” said Jagusch. “We then used a slip sheet and installed 1-inch-high, double lock, 17-inch-wide, 16-ounce copper standing seam panels.”

Panels were roll formed at the Wagner metal shop out of 20-inch-wide coils using an ESE roll former and trailered to the jobsite. Approximately 5,400 square feet of copper panels were installed on the project. The double-lock seams were mechanically seamed. Twenty-ounce copper flat-seamed panels were used in the large valleys.

The safety plan included full scaffolding during every phase of the project. “We have our own safety scaffolding system,” Jagusch says. “Our guys demand it on our jobs, and we demand it of them to come home safely every day. We are very proud of our safety record. It’s front of mind for us.”

In addition to the roof, all of the metal cladding was replaced on the southeast feature wall. The top of the wall was reconfigured to accommodate the new sloped valley. Where the wall met the roof, a band was fabricated to match the top part of the fascia. Other details included copper cladding for the chimney.

Drainage was redirected to the perimeter, where custom-fabricated gutters were installed. “On the west side, the roof was originally designed to dump off straight onto a rock feature on the ground, but we fashioned a custom copper box gutter about 35 or 40 feet long,” Jagusch states.

At the either end of the large internal gutter and at the end of a large valley, shop-fabricated copper conductor heads were installed. Custom five-sided downspouts were fabricated, but installing them posed another challenge, as large window areas offered few options for support. The downspouts had to be snugged up under the framing system.

“Everything had to work with the other building components,” Jagusch explains. “One of the tougher things on this project was being able to have the function and the form both top of mind, in that order. The key was to make the functional stuff look good.”

Showpiece Project

The project was completed about a year ago, and the copper has begun to change in color. “The copper now has a gorgeous bronze, kind of purplish hue to it,” notes Jagusch. “I think it will eventually develop a green patina, but with the way the environment is these days, I think it will take 15 years or so before it gets to that point. That’s the cool thing about copper—it’s a natural, breathing material that is constantly changing, constantly evolving.”

Wagner Roofing has a maintenance agreement in place on the home, so Jagusch has stayed in touch with the owners and kept tabs on the project, which is performing well. “I’ve got just one hell of a team here,” he says. “It wasn’t just one estimator that went out and brought this thing in. In our business, estimating and roofing is a team sport. We kicked this thing around a lot with all divisions of the company, from estimating to operations to the actual installers before we finally settled on a number for this thing.”

“We work on some pretty spectacular places, and of course this is one of them,” he concludes. “We like a challenge, and this is the stuff that my team really loves to get their teeth into.”

North Carolina Middle School Generates More Energy Than It Uses


North Carolina Middle School Generates More Energy Than It Uses

Sandy Grove Middle School in Hoke County, N.C.

When Robbie Ferris first presented the idea of a school building that generates more energy than it uses, people were skeptical. Now he can point to Sandy Grove Middle School in Hoke County, N.C., as proof that a high-performance school building can go well beyond net zero and generate 40 percent more energy than it consumes.

Ferris is the president of SfL+a Architects and manager at Firstfloor, a development company that specializes in public-private partnerships and design-build-operate agreements. “We designed the building, we own it and we lease it to the school district,” he says. “We monitor all of the systems remotely. One of the reasons we do that is because when you put really high-performance systems in buildings, you have to make sure they are operating at peak efficiency. It can take time to make sure everything is optimized.”

Three years after completion, Sandy Grove Middle School is outperforming its energy models, and the building continues to win accolades. It recently received Energy Star 100 Certification and has been recognized as the nation’s most energy positive school.

“Sandy Grove Middle School is a perfect example of a high-performance facility,” says Ferris. “With the public-private lease-back model, everyone wins. The students receive a quality school, it fits in to the school system budget, and it is energy efficient to help both total cost and our environment.”

The building’s systems were designed to be as energy-efficient as possible, and that includes the roof, which features an array of photovoltaic (PV) panels to generate electricity. “We wanted a roof that would last 30 years,” Ferris notes. “We’ve had a tremendous amount of success with TPOs, and metal roofs as well. This particular client wanted a metal roof look from the front, but they were very open to a membrane roof on other parts of the building. We made the decision to put the metal roof on the front of the building and a TPO on the wings at the back of the building.”

On this project, the warranties were important considerations, along with durability and energy efficiency. SfL+a specified a standing seam metal roof system manufactured by Dimensional Metals Inc. and a TPO system manufactured by GenFlex. “Obviously, if you’re putting a couple of million dollars’ worth of solar panels on your roof, you want to make sure you have a roof that is going to be problem free.”

A Smooth Installation

The installation was a challenging one, but everything went smoothly, notes Aaron Thomas, president and CEO of Metcon Inc. Headquartered in Pembroke, N.C., Metcon is a full-service general contractor that specializes in energy positive commercial buildings, so it was perfectly suited to serve as the construction manager on the project.

Photovoltaic panels were installed

Thomas and Ryan Parker, senior project manager with Metcon, coordinated the work of subcontractors on the job, including the Youngsville, N.C. branch of Eastern Corp., which installed the TPO and metal roofs, and PowerSecure, the solar installer on the project, based in Wake Forest, N.C.

The roof systems covered 85,000 square feet, and Sharp PV panels were installed on both the metal roof and the TPO system. Solar panels were also installed on freestanding structures called “solar trees.” Each solar tree is 20 feet tall, 25 feet wide and weighs 3,200 pounds.

“The TPO roof system was upgraded to an 80-mil product due to solar panels being added to the roof,” Parker notes. “It was 100 percent ballasted on the low-slope sections, with slip sheets being used below the racking on the TPO roof.”

On the metal roof, clips manufactured by S-5! were used to affix the solar racking to the seams. “There are no penetrations for the frames, and penetrations for the electrical wiring went through vertical walls, not the roof,” Parker says. “There were no penetrations anywhere in the roof system, which made all of the warranties that much easier to keep intact.”

The biggest challenges on the project, according to Parker, were coordinating the different scopes of work and ensuring all of the manufacturers’ warranty considerations were met. “We had two different kinds of roofs, both coupled with solar panels,” Parker says. “Like any rooftop with photovoltaic products, there had to be special attention paid to the warranties of all parties involved. Both Genflex and DMI were closely involved in coordinating details to ensure that the owner achieved a great roof free of defects.”

One key was developing a detailed schedule and keeping everyone on it. “We would meet once a week and huddle up on how it was progressing and what else needed to be done,” Parker recalls. “We found that by using a collaborative submittal sharing platform, all of the varying parts and pieces could be checked by all parties to ensure compatibility.”

There were multiple safety concerns associated with combining solar panels to the roofing system, so everyone had to be on the same page. “The roofing subcontractor and the solar subcontractor performed a joint safety plan that utilized common tie off points,” Parker notes. “The job had zero lost time.”

“Everyone coordinated their work and it was a great team effort,” Ferris says. “It was one of the smoothest jobs I’ve ever seen. We have not had a single leak on that project—not a single problem.”

Proof Positive

For Ferris, the greatest obstacle on energy-positive projects convincing members of the public and governmental agencies of the benefits. “The biggest challenges had nothing to do with construction; they had to do with just doing something new and different,” he says. “The toughest challenge was getting the school board, the county commissioners, the public and the review agencies on board. It took a very long time—and lots of meetings.”

Now Ferris can point to Sandy Grove as an example of just how a high-performance school building can pay huge dividends. “As soon as you see it in real life, you’re on board,” he says. “It’s very exciting for people to see it. If we can get people to the school, they’ll walk away convinced it is the right thing to do.”

With Sandy Grove, the school district has a 30-year lease with an option to purchase. Ferris believes the lease model is the perfect solution for educators. “We’re responsible for any problems for the life of the lease,” he says. “If a problem does come up, we usually know about it before the school does because we monitor the systems remotely online.”

“In their world, buildings are a distraction from educating kids,” Ferris concludes. “This is one building that is not a distraction.”

Southern Charm: Graham Roofing


Southern Charm: Graham Roofing

Bobby Hooks started a roofing company with two friends as a means to make money while still in college. Nearly five decades later he’s built a business legacy that rivals any competitor in his market, and fostered an extended family of loyal employees still getting it done on a daily basis — continuing to make Graham Roofing Inc. (GRI) one of strongest commercial and industrial roofing firms in the Deep South.

While it may not have been the original plan he had in mind when he entered Mississippi State University in 1968, roofing turned out to be the best avenue for Hooks to put his long-standing work ethic and years studying at MSU’s College of Business and Industry to the test. After college, the trio continued to work on the business and officially incorporated in 1971, a few years before the EPDM explosion and other product advancements revolutionized commercial roofing across the country.

New Construction Project Tests Contractor’s Mettle

Independence High School in Frisco, Texas, was conceived as an impressive new construction project on a tight schedule. The standing seam metal roof of the building was a key component in the architectural planning, as it was designed to provide aesthetic appeal for the massive structure while minimizing the view of mechanical equipment for passers-by on the ground.

The roof also was comprised of several low-slope sections, which were covered with a modified bitumen system. Both the metal and modified systems contributed to the building’s energy efficiency, helping the project achieve LEED Silver status.

The roof systems were installed by the Duncanville, Texas, branch of Progressive Roofing Services. Randy Dickhaut, the company’s general manager, indicated the project was completed in approximately one year—an ambitious schedule for a job of this size. “It was a challenging new construction job,” he says. “There were a lot of logistics involved, but in general, the job went very well.

A Tale of Two Roofs

The first goal of the project was drying in the metal decking. A two-ply, hot–mopped modified bitumen system manufactured by Johns Manville was installed on 24 decks totaling approximately 195,000 square feet of low-slope roof area. The system was applied over two layers of 2 1/2-inch polyiso insulation and 1/2-inch JM Securock cover board. The system was topped with an Energy-Star rated cap sheet, DynaGlas FR CR.

In the nine sections where the 88,000 square feet of metal roofing was installed, two layers of 2 1/2-inch polyiso insulation were attached, along with plywood decking and self-adhering TAMKO TW Tile and Metal underlayment. The standing seam metal roof system was manufactured by McElroy Metal, and the company provided the manpower and equipment to roll form the panels on the job site. Roof panels were the company’s 22-gauge Maxima 216 panels in Weathered Galvalume. These panels were complemented by 24-gauge Flush panels on walls and soffits.

The roll former was mounted on a scissor-lift truck. The eaves of the building were approximately 36 feet off of the ground, so a sacrificial panel was used to create a bridging effect to help guide panels to the roof. “Basically, the roll former went right along with us,” Dickhaut recalls. “We would pull 30 or 40 squares of panels, then drop the machine and move to the next spot. We were able to roll the panels right off the machine and lay them in almost the exact spot they would be installed.”

Photos: Lynn Cromer Photography, Ferris, Texas

The length of some of the panels posed a challenge, and as many as 12 crew members were needed to guide them into place for installation. In the steep-slope sections, crew members had to be tied off 100 percent of the time, so retractable lanyards were used to help keep safety lines out of the way.

The roof was mechanically seamed using a self-propelled industrial roof seamer manufactured by D.I. Roof Seamers. “We call it walking the dog,” notes Dickhaut. “One man can operate the equipment, and he just walks it every inch of every seam.”

The metal roof was designed to hide the mechanical equipment for the building, and Progressive Roofing completed work on two deep mechanical wells before the HVAC equipment was installed. “In the wells, we used McElroy’s Flush panels for the vertical surfaces and transitioned to the metal roofing,” notes Dickhaut. “In the bottom of the mechanical wells, we installed the Johns Manville modified roof and flashed the curbs.”

Rising to the Challenge

Dickhaut points to a few challenges on the job, including the length of the panels and the weather. “Overall, the job went really well,” he says. “The architects did a great job on the design, and McElroy has really good details. It was a pretty straightforward process. There was a lot of wind and rain we had to cope with. When you have a 100-foot panel that you can’t kink or scratch, it can get kind of tricky. You just have to be very careful.”

The Texas weather made the schedule unpredictable. “We were on that job over a year, so we caught all four seasons,” he says. “Weather had a huge impact. We dealt with extreme heat, humidity, snow, ice, mud, monsoon-type rains. Texas throws anything and everything at you.”

Whatever the conditions, Progressive Roofing was ready. “We show up locked and loaded,” Dickhaut says. “We attack it. We have seasoned veteran roofers that lead the pack. On that particular project, we had an architect, roofing consultants, an owner’s rep, and a general contractor. We would also bring in the McElroy and JM reps periodically for consultation. It’s really a team effort.”

Preserving History at Indiana State University


Preserving History at Indiana State University

The State of Indiana approved a $16 million renovation project

Completed in 1909, Normal Hall is the second oldest surviving building on the Indiana State University campus in Terre Haute, Ind. Since then, Normal Hall has undergone multiple renovations, including an addition added in 1957. But by 2010, the grand neo-classical building was largely unoccupied and falling into disrepair. The hall maintained its perch at the center of campus, but years of service to its tens of thousands of students had taken their toll.

“We try to preserve the history of ISU here on campus,” says Seth Porter of ISU facility management. “But between roof leaks and other issues, it was becoming an eyesore.” So, the State of Indiana approved a $16 million renovation project and partnered with architectural firm arcDESIGN to bring the building back to life.

“This renovation will return Normal Hall to its rightful place in the center of campus life,” says ISU President Dan Bradley. “The project will provide a valuable new resource to students while preserving and re-energizing a significant historic structure in the heart of campus.”

Aside from the stately Indiana limestone, the building had to be redone from the foundation to the roof. And the history that makes Normal Hall special also made for unique challenges in the design and renovation process.

They Don’t Build Them Like They Used To

“People will say, ‘They don’t build them like they used to,’” says Greg Miller, project manager from arcDESIGN. And in many cases, “It’s a good thing they don’t!”

Normal Hall has undergone multiple renovations

Normal Hall was originally designed for and used as the university’s central library. At that time in history, after the Civil War and before the 1920s, libraries were built in a certain way. Due to open flames of gas lighting and unreliable supply of electricity, indoor lighting at the time could have been dangerous to a library’s collection. So, libraries were designed to maximize natural light, with plenty of windows, skylights, and even glass floors. Instead of structural walls, Normal Hall’s six levels of bookshelves—or “stacks”—were designed to be structurally self-supporting, independent of the rest of the building.

Miller led the design team through the challenging process of removing the six-level stacks and replacing them with four new floors for offices and building systems. A portion of the stacks system was salvaged and reconstructed, providing the same view patrons would have had more than 100 years ago.

The Biggest Challenge

During construction, crews discovered unstable structural conditions on the north side of the building adjacent to the original six-story stacks system. The entire exterior wall had to be removed and replaced, all while supporting the existing attic and roof nearly 60-feet above the ground floor.

To do this, crews constructed a mammoth 60-foot-high temporary structural system in and through the six-story iron stacks system still in place to support the original attic and roof deck. The north wall was completely removed and reconstructed. Structural steel columns supporting roof trusses were replaced while ends of deteriorated roof trusses were reconstructed in place.

“It was a monumental feat,” Miller says. “It was a great example of teamwork by Indiana State University, design consultants and the contractor.”

The Roof System

For the roof replacement portion of the project, arcDESIGN collaborated with The Garland Company Inc., a leader of high-performance roof and building envelope solutions. Garland worked with local roofing contractor Associated Roofing Professionals (ARP) to install a new modified bitumen roof system with a high albedo coating.

All existing roofing was removed to structure and Garland’s StressPly EUV fiberglass-polyester reinforced, SBS and SIS modified bitumen membrane was installed to provide long-term waterproofing protection.

The roof was then coated with Garland’s Pyramic white, nontoxic, acrylic coating, which helps preserve asphaltic or modified bitumen surfaces and significantly reduces under-roof temperatures to create a more energy-efficient environment.

“ISU has a strong commitment to the environment, and we were able to help them achieve their performance goals while also contributing to LEED credits with our environmentally-conscious products,” explains Rick Ryherd, area manager for Garland.

The largest—and brightest—rehabilitation involved the stained-glass dome atop Normal Hall. The original dome had deteriorated so extensively that, by the middle of the 20th century, the remaining glass panels were completely removed and the dome was completely hidden. A suspended plaster ceiling sealed off the once grand rotunda. “Imagine just a skeleton, an empty dome with only the ribs visible,” said Miller.

The dome restoration began with historic photos, documents and forensic analysis. The glass art featured distinguished educators and philosophers. Some of the original stained-glass panels were recovered from the building, whiles others had to be recreated. Conrad Schmitt Studios, in Wisconsin, restored the stained glass to its former glory. With the stained glass restored, rehab on the rotunda continued. Inside Normal Hall, the rotunda mural was restored and more than 140 light bulb sockets were re-wired to light the dome. Above the dome, a new 40-foot octagonal skylight was installed, along with supplemental lighting. Below the rotunda, 20 original columns that stretch through the open hall were restored with scagliola and paint finishes.

The crew worked to save original hardware and finishes that hadn’t already been lost to time. They were able to restore and replicate plaster moldings and cornices, save original wood doors and casings, and restore the grand marble and bronze staircase. “The general contractor did a great job preserving the historic detail with the extra time they put into restoring this building,” notes Porter.

The Future of Normal Hall

With all the time and effort put into preserving the history, the team did not forget to focus on the future of Normal Hall. The team, starting with arcDESIGN, incorporated the old and the new seamlessly.

For starters, Miller said the design was intended to respect but not imitate the building, which is listed on the National Register of Historic Places. Rather, he said, “the design clearly communicates original versus new construction to patrons.” Miller consulted experts from the team, from historians to a representative from the roofing manufacturer to gather the full scope of the project.

Today, the original stately limestone structure is accentuated by the addition, comprised predominantly of glass and Indiana limestone. The addition houses functional requirements such as stairs, elevators, restrooms and mechanical services, maximizing use of the historic interior spaces.

The renovation was planned and constructed to achieve LEED Certification by the USGBC. Renovation included new HVAC systems utilizing the university’s existing central steam heating plant that runs on natural gas. LED lighting throughout is an energy efficient replacement for the building, originally built with combination gas and electric light fixtures.

100 Years in the Making

Re-dedicated in October 2015, Normal Hall is back in action at the center of campus as home to the university’s Center for Student Success and numerous tutors, counselors and mentors. Below the rotunda, more than 100 years after the building opened its doors, students gather in the university Reading Room and Gallery modeled after the original hall when it opened to students in 1909.
