Summertime is the busy season for school construction projects, and as students prepare for vacation, restoration work heats up. At Strober-Wright Roofing Inc., a full-service roofing contractor headquartered in Lambertville, N.J., going to school in the summer is a big part of the company’s business plan.

The company is owned by Mike Strober, Mark Wright and John Foy, who share more than 100 years of experience in new construction, additions and re-roofing projects. “We specialize in schools,” says Robert Shoemaker, an estimator with Strober-Wright, who points to attention to detail as the key to succeeding in the competitive bidding market. “You have to sharpen your pencil. You have to understand what your crews can do and how fast they can do it. You have to know what their skills are.”

Mark Wright has been with the company 26 years, and he points to a recently completed project at Montgomery Lower Middle School in Skillman, N.J., as an example of just what Strober-Wright can do when faced with large-scale projects and tight deadlines. “We have the men and equipment to get these types of jobs done on time with high-quality workmanship,” he says. “That’s our strength.”

Wright and Shoemaker believe building relationships is essential in this segment of the market. “We’ve done a lot of schools,” Shoemaker says. “When our bid is successful, people breathe a sigh of relief and tell us they are happy to have us on their projects.”

The Roof System

The Montgomery Lower Middle School project was a complete tear-off and re-roof of a school complex encompassing several connected roof sections totaling approximately 130,000 square feet. There were two types of existing roof systems: a fully-adhered EPDM system and a ballasted EPDM system. These were torn off and replaced with a two-ply, hot-mopped modified bitumen system.

Tapered polyiso was installed to ensure proper slope to the drains, which were surrounded by an 8-foot tapered sump.

The Strober-Wright team looked for ways to make the installation as efficient as possible in order to meet the deadline. The original specification called for removing and replacing more than 100 existing roof drains, but the company suggested using SpeedTite drains from OMG Roofing Products instead.

“My partner, Mike Strober, came up with the idea to use the OMG drains, and we submitted it to the architect,” Wright notes. “The architect approved them. The key with these drains is you don’t need another trade to install them. They install quickly and minimize disturbance in the building because the drains drop into the pipe, bypassing the bowl. You don’t have to take the old bowl out and put a new bowl in. You don’t have to take ceiling tiles out and create a mess inside the building.”

Show Your Work

On the ballasted roof sections, the stones were removed by Adler Vacuum. Then the existing EPDM roof was removed in sections. “We’d take a section out and replace it the same day so the building was watertight every night,” Wright explains.

At the end of each day, the old system was tied off to the new section. “With the existing rubber roof, we would leave a little extra material and flop it back,” Wright notes. “We’d adhere the flap using hot tar to the new system, and just peel it back the next day and go again.”

On sections of the roof with metal decking, the 4-inch base layer of flat polyiso insulation was mechanically attached with fasteners and plates. On the sections with concrete deck, the concrete was primed with a quick-drying asphalt primer and the base insulation was then adhered in hot asphalt. The tapered insulation was then adhered in hot asphalt to ensure proper drainage.

After the cover board was secured, the modified bitumen system was installed. The base ply and cap sheet were set in hot asphalt. Once the roof system had properly cured, it received two coats of an aluminum reflective coating.

Safety is always top of mind, but there were no unusual safety issues on the project, notes Wright. “We followed our standard safety protocols,” he says. “You have to make sure you’re wearing proper clothing and safety equipment with hot asphalt. We set up a safety perimeter warning with flags. If you were outside the perimeter, you had to wear a harness and be tied off at all times.”

Going With the Flow

More than 100 new drains were installed. The existing strainer domes, clamping rings and hardware were removed, but the drain bowls were left in place. The SpeedTite Drains were inserted, and the mechanical seal was tightened to provide a secure connection to the existing drain leader.

According to the manufacturer, the drains have a built-in vortex breaker to help improve water flow and a mechanical seal that meets the ANSI/SPRI/RD-1 standard (holding a 10-foot column of water for 24 hours without leaking).

More than 100 drains had to be replaced on the school. Strober-Wright suggested using OMG SpeedTite drains, as they could be installed more efficiently than conventional drain replacement and caused less disruption in the building.

After the drains were flashed in, the clamping ring and strainer dome were installed. “The drains are flashed with the base ply and then a piece of the cap sheet over that, so it’s a two-ply flashing system,” notes Wright. “The architect here specified an 8-foot tapered sump, and that’s a nice thing because you have an 8-foot area around the drain that’s really going to flow. It works really well.”

A Tough Schedule

Work on the project began in late June and was completed in late August, just in time for the school year to begin. Crews averaged 12 people and completed approximately 50 squares of roof per day.

According to Wright, the toughest part of the project was the tight schedule, which was made even more difficult due to inclement weather. “It was a wet summer,” he says. “It seemed like we were constantly battling rain, and we had to make sure we didn’t get behind the eight-ball on the schedule. You can’t work when it’s raining. You have to just batten down the hatches and prepare to get started the next day.”

After the drains were flashed in, the clamping ring and strainer dome were installed. The drains feature an internal vortex breaker.

The company followed the weather report closely to plan each day’s production. “We have a weather company out of Hackettstown we use called Weatherworks,” Wright says. “When it comes to the weather—up to the minute, 24 hours a day—they are on top of it. They deal with nothing but New Jersey weather. We pay for the service, but it’s well worth it. Saving one day’s worth of work can pay for the whole year’s subscription.”

Despite the weather, work was completed on time and on budget. The project achieved the priorities the school system wanted: a durable, energy-efficient roof system with a 25-year warranty. “It’s a great system,” Wright states. “We make our bread and butter on these jobs. We hit our deadline, and now it’s on to the next one.”

Restoring Natural Slate Roof Takes Expert Craftsmanship

Photos: Charles F. Evans Company Inc.

When it came time to replace the roof on Howard W. Jones Hall, Youngstown State University wanted to closely re-create the original graduated natural slate roof. Photos: Charles F. Evans Company Inc.

Even slate roofs have to be replaced sometime.

Howard W. Jones Hall is one of the oldest buildings on the campus of Youngstown State University in Youngstown, Ohio. The limestone structure with its twin towers is an iconic structure, and when the original slate roof finally deteriorated, the university wanted to keep the stately look of natural slate on the building’s exterior.

Charles F. Evans Company Inc. of Elmira, N.Y., was awarded the Jones Hall restoration job in early 2017 and named 37-year veteran Ken Dennison as the project manager. “We seem to excel in doing difficult projects, including specialty systems of slate, tile, and architectural sheet metal,” Dennison says. “We emphasize quality workmanship and uncompromising customer satisfaction. We also emphasize safety, and currently we are the only roofing contractor to be an approved OSHA VPP mobile Mobile Workforce STAR contractor.”

The university wanted to replicate the existing 6,500-square-foot graduated slate roof with random widths, and slate roofing tiles in the same color and size range were chosen. The scope of work included repairing the existing masonry and installing copper gutters, valleys and flashings.

Going Old School

The first step was removing the old slates, which proved a tough task. “We had to remove them almost one by one,” recalls Dennison.

Copper details were custom fabricated for counterflashing and step flashing.

The existing wood plank deck was in very good shape, and Carlisle Water & Ice Protection self-adhering underlayment was installed at the eaves, valleys and rakes. It was also applied around all of the details. Then two layers of 30-pound felt were tacked into place with plastic-capped nails.

Natural hand-split roofing slate was delivered pre-cut and pre-punched by Evergreen Slate Co., located in upstate New York. The slates were mixed to ensure proper color distribution and arranged in piles for installation on the site. Once the underlayment was in place, the slate was installed just as it might have been a century ago. “We used copper nails,” Dennison notes. “Everything was nailed by hand—two nails per slate.”

The installation called for a 3-inch head lap. “With random slate, you don’t need to put any vertical lines in, because nothing is going to line up vertically,” Dennison explains. “Every side lap has to be at least 3 inches, but there is no set pattern for the widths—we just mix them up. That’s why they use the term ‘random.’”

Handcrafted copper details completed the distinctive, traditional look. Flat-seam copper panels from Revere Copper were installed in the valleys, using clips to allow for expansion and contraction. Copper counterflashing and step flashing were also custom fabricated. “We bend it to fit whatever we might need,” notes Dennison. “We have a talented sheet metal shop at our office where we fabricate the big stuff, but we also cut and shape panels on site.”

A detailed safety plan was set up for the building, which was open and active during the entire installation process. Scaffolds with decking were erected at the eaves, and temporary tunnels were engineered to protect pedestrians at the entryways.

The rake edges did not have scaffolding, so a safety perimeter was set up 6 feet from the roof edge. Workers outside the line had use a personal fall arrest system, which was secured to anchors screwed into the rafters. “All of our mechanics are extensively trained, and each year everyone goes through additional training sessions,” Dennison says. “We all know what we’re supposed to do. We have a very stringent plan on project safety.”

Slate itself can pose its own set of safety concerns. “Slate can be heavy and sharp,” Dennison says. “It’s rock. You have to be very careful, but the guys that do it love it. A lot of roofs these days are totally hidden. On a slate project, at the end of the day you can step back, see what you’ve done, and be proud your work.”

Charles F. Evans is just putting the finishing touches on the roof at Jones Hall. “When we’re done with a project and the customer is happy, that’s the best satisfaction you can get,” Dennison says. “When the client is happy and you look back and see a beautiful product that you know you had a hand in—that’s what I like about it. A slate roof is really a work of art that will stand the test of time.”

Metal Barrel Roof Tops the Rebels’ New Basketball Arena

The Pavilion at Ole Miss is a multi-purpose facility that is most famous for hosting the University of Mississippi’s basketball team. The arena cost approximately $97 million to build and seats 9,500 fans. The building’s signature arched metal panel roof was designed to complement the curved entrance and blend in with other architectural features on the university’s campus in Oxford, Miss.

Professional Roofing Contractors of Shelbyville, Tenn., was originally called in to assist with estimating the cost of the structure’s main roof, as well as a membrane roof system on the lower level. Upon final bid results, the decision was made to proceed with a standing seam metal roof on the upper portion of the building and a PVC roof on the lower level. Professional Roofing was the successful low roof bidder and selected ACI Building Systems to provide the standing seam roof materials and Sika Sarnafil to provide the PVC membrane roof materials. Professional Roofing installed both systems, with Jose Martinez as the crew leader for the membrane roofing portion and Dale Jones in charge of the metal roofing crew.

Larry W. Price, president of Professional Roofing, and Jonathan Price, the company’s vice president and the production manager on the project, oversaw the installation of 79,500 square feet of standing seam metal roofing and 46,500 square feet of PVC. There wasn’t much room for staging material on the jobsite, which didn’t give the company much room to maneuver. For the main roof, bundles of pre-cut metal panels were trailered in by ACI and loaded to the roof by crane.

“Logistics were complicated,” notes Larry Price. “Just getting a big enough crane in there and lifting the panels was difficult. Once we got the panels on the roof and they were situated, the roofers could just move ahead.”

Panels were installed with a 2-inch-high, double-lock standing seam, which was completed using a self-propelled mechanical seamer from D.I. Roof Seamers. The metal panels were curved into place by crews on the roof, who installed them over the staggered metal deck after it was covered with two 2-inch layers of polyiso insulation and Carlisle’s WIP 300 HT self-adhered underlayment. “The metal deck was segmented,” notes Jonathan Price. “We had to bridge some of those sections to make a nice, smooth curve.”

The scope of work included a large gutter at the roof edge. The gutter was 3 feet high and 2 feet wide, and crews from Professional Roofing flashed the gutter and lined it with the same Sika Sarnafil PVC used on the lower roof.

On the mezzanine level, crews installed a vapor barrier and mechanically fastened two 2-inch layers of polyiso insulation, as well as some tapered insulation for drainage. Once that work was completed, the 60-mil PVC was applied.

“Everything went pretty smoothly,” says Jonathan Price. “Logistics are usually tight on a new construction project, but once we adjusted to that, we just had to cope with the weather.”

“We had a lot of hot days and some rainy days,” Larry Price remembers. “Mississippi in the summer can get hot, hot, hot—and when it’s not hot, it’s raining.”

Innovative Curved Canopies Protect Bus Passengers at Ole Miss

When the University of Mississippi decided to renovate and expand the bus shelter area near Kennon Observatory on its Oxford, Miss., campus, an architecture firm and a manufacturer teamed up to design two striking curved glass canopies to protect passengers.

Duo-Gard, based in Canton, Mich., collaborated with a team from Cooke Douglass Farr Lemons Architects + Engineers in Jackson, Miss., to develop the plans. Located side by side, the canopies measure 11 feet by 92 feet and 11 feet by 61 feet, and their curvature reflects the transit loop area.

The project also had some interesting and challenging design goals, according to team leader Clark H. Wells, an architect on the project. “Certainly we wanted the bus structures to protect students, but we also wanted them to blend in with existing campus architecture, which has a historic uniform look of brick and metal,” Wells says. “We wanted the structures to disappear, and they are the first buildings like this at Ole Miss.”

Wells achieved the desired “disappearing act” by constructing the roofs with glass. “They fade into the sky, becoming less obtrusive than other options, and so the structures don’t detract from the site’s visual appeal,” Wells notes.

Duo-Gard engineered the architect’s custom design with half-inch-thick glass, which includes a vandal-resistant film. Duo-Gard also provided steel columns and structure from its in-house fabrication facility. The system was installed by Murphy & Sons, headquartered in Southaven, Miss. Each of the panels is 5 feet by 10 feet and weighs 350 pounds.

Architectural Shingle Roofing System on New Field House Helps St. David’s Prepare for the Future

Originally founded in 1972 as a high school, St. David’s Episcopal School now serves students in pre-K programs all the way through graduation. Located on a wooded campus in suburban Raleigh, N.C., the school now attracts students from Raleigh, Durham, Chapel Hill, Wake Forest and Cary. And as the student body grows, so does the campus of St. David’s.

The school’s facilities are being built with the future in mind, and when the decision was made to add a new athletic field house, durability and longevity were key factors in the decision-making process.

For the roof on the new complex, the school turned to Baker Roofing and Executive Vice President John Matthews, a parent of two St. David’s students who has worked with the school for the past decade. To ensure that the campus itself was built for longevity, Matthews selected 60 squares of Atlas Pinnacle Pristine shingles in Pristine Desert. Other products installed on the project include ProCut Hip & Ridge Shingles, ProCut Starter Shingles, and Summit 180 Synthetic Underlayment.

The architectural shingles feature Scotchgard Protector, which will help the field house maintain its appearance by resisting ugly black streaks caused by algae. In fact, more than 80 percent of the roofs in the U.S. are prone to algae invasion, so protection is the key to a long-lasting roof. “Having the Pinnacle Pristine shingles means the school will have the best protection and appearance,” Matthews says.

His personal relationship with St. David’s and his commitment to the donors who made the new construction possible meant that this project was especially important to Matthews. “The quality education provided by St. David’s is critical to shaping young lives,” he says. “With that in mind, it was essential I feel confident in the products we installed. Knowing that Atlas stands by its products made me sure of the roof the school would be receiving. The extended premium protection period on the Signature Select Roofing System gave everyone a lot of confidence in the decision to go with Atlas.”

On a campus where everything they do is geared toward the future, building a facility with longevity in mind is key. “Knowing my own children attend St. David’s and our family is a part of this community made it extremely important that the work we do and the materials we chose be of superior quality,” Matthews notes. “The Atlas system is a product that will ensure the building offers lasting protection and a beautiful appearance for years to come.”

School Board’s Kite-Shaped Building Reflects Location’s History

The roof design for the Homewood Board of Education Central

The new home for the Homewood Board of Education Central Office in Alabama is a 14,500-square-foot modern structure that marks the first phase of a long-term development plan on a 24-acre site in Homewood, Ala., a suburb of Birmingham.

The contemporary structure was designed by Williams Blackstock Architects in Birmingham. “The roof design was inspired by the site, which is known as Kite Hill,” says architect Kyle Kirkwood. “It’s a spot where kids and parents come to fly kites. The roof, which slopes in two different directions and is kite-like in its appearance, is representative of the popular site.”

The building was conceived as a “garden pavilion” integrated within the site, intended to mediate between public and private property, and man-made and natural materials. The structure is nestled into a line of pine trees with a cantilevered roof extending just beyond the pines.

The design incorporates approximately 24,000 square feet of Petersen’s PAC-CLAD material in four different profiles. The main roof includes 16,000 square feet of Petersen’s Snap-Clad panels up to 60 feet long. The design also incorporates an interior application of the Flush panels by integrating them into the lobby area. In addition, 7,000 square feet of Flush panels were used in soffit applications. The panels were manufactured at Petersen’s Acworth, Ga., plant.

The roof design was complex, Kirkwood notes. “Since the roof slopes in two directions, we had an interesting valley situation where we had to coordinate the orientation of the seams,” Kirkwood said.

Challenging Installation

The roof also features two rectangular low-slope sections that were covered with a TPO system manufactured by Firestone Building Products. The roof systems were installed by Quality Architectural Metal & Roofing in Birmingham, which specializes in commercial roofing, primarily architectural metal and single-ply projects.

Eddie Still, Quality Architectural Metal & Roofing’s vice president, helped prepare the budget for Brasfield and Gorrie, the construction manager on the project, so Still was prepared to go when his bid was accepted. “It was a job that consisted of a large portion of metal and a smaller portion of TPO,” he says. “Since we do both things, we were a good fit.”

The installation was made event tougher by the logistics of the site, according to Still. “The design of the metal roof was unusual, to say the least,” he says. “It had a valley that cut through it, and the panels were sloped in two directions. That’s not normally the case.”

The biggest obstacle was posed by the building’s location on a hill near the edge of the property line, immediately adjacent to a residential neighborhood. “The Snap-Clad panels were approximately 60 feet long, which isn’t a problem if you have the equipment to handle them,” Still notes. “It does pose a problem logistically when it comes to getting them into a tight area, and we definitely had that.”

Panels were trailered in and hoisted to the roof by a crane. “Once the panels were up there, the installation was fairly easy,” Still says. “The roof didn’t have a lot of changes in elevation or different plateaus built into it. The only quirky thing was that valley, and once you had that squared away, you were good to go.”

Coordinating penetrations with members of plumbing and HVAC trades is critical, according to Still. “On the metal roofs, we always stress that you’re trying to present an aesthetic picture for the building, so you want to minimize the penetrations so it looks cleaner,” he says. “You have to coordinate on site so if you have a plumbing exhaust stack, it comes up in the center of the pan and not on the seam.”

The metal roof incorporates approximately 24,000

A small section of metal roof near the entryway was made up of mechanically seamed panels. “The reason we used Tite-Loc panels on that portion of the roof was because of the low slope,” Still says. “We used the same width panel, so it looks identical, but the seams are different. They are designed to work on systems with slopes as low as ½:12.”

Quality Architectural Metal & Roofing also installed the Firestone self-adhered TPO roof system on two low-slope sections of the roof, totaling approximately 3,000 square feet.

Still looks back on the completed project with pride. “Our niche would be a building like this one, which has TPO or some other membrane roofing and metal,” he says. “We’ve been in business 33 years. We have a well-deserved reputation for the type of work we do. In the bid market things are price driven, so more often than not, price is the determining factor. But in larger projects and work that’s negotiated, the G.C. is going to opt to choose people to solicit pricing from who have a history of doing successful projects with them.”

New Shingles Speed Up Installation Process in First Test in the Field

This residence in the Atlanta area

Atlas shingles with HP42” technology, a new format introduced in July, were recently installed on a home in the Atlanta area. It is the first roof in the country to be installed with the new shingles, and the homeowner, contractor and manufacturer are all pleased with the results.

Larger than any shingle currently made in the United States, the HP42” shingle format results in a faster installation, as well as significant savings in labor and materials for contractors, according to the manufacturer. HP42” format shingles are the new standard for the Atlas StormMaster Shake, Pinnacle Pristine and ProLam shingle lines.

“These new high-performance HP42” format shingles are larger and better engineered, which makes them easier and faster to install,” says Paul Casseri, product manager of Atlas Roofing Shingles and Underlayment Division. “As a result, contractors and crew can expect a drastically improved installation experience.”

Faster on The Roof

Contractor Dirk Gowder of Ryno Roof in Atlanta says the HP42” shingle format made the project a breeze. “The larger shingle sped up installation time by about 10 percent because there’s less waste, more courses per run, and there’s less cutting of the shingles,” Gowder explains.

With the benefit of using fewer shingles and experiencing less waste, this particular job was easily completed in one day, giving Gowder’s guys plenty of time to do the finishing touches and clean up around the home.

The Ryno Roof crew also installed Summit 60 Synthetic Underlayment, Atlas Pro-Cut 10X Starter Shingles and Pro-Cut Hip & Ridge Shingles featuring Scotchgard Protector, which helps a home maintain its appearance by resisting ugly black streaks caused by algae. The project used Atlas Pinnacle Pristine shingles in Pristine Hearthstone, seamlessly mixing both HP and HP42” format shingles on the roof.

Mix and Match

“The install process, even with the mixed shingles, couldn’t have been simpler,” Gowder says. “It was an easy transition from the standard-sized shingles to the 42-inch shingles. The new HP42” format shingle fits the pallet perfectly, so all of the shingles were nice and straight and flat when we opened every single bundle. My guys moved through the install just like they would have if this were a standard roof job with only one type of shingle. The Atlas quick start guide had clear, easy-to-follow instructions that made the job go smoothly.”

The old format of the Atlas HP shingles and new HP42” format shingles both have the same 6-inch exposure, which allows them to be mixed on a roof—as long as the products come from the same plant. Shingles made in different plant locations may contain a different granule blend and can vary in color.

For any roof installation, contractors should follow the manufacturer’s printed installation instructions, which include keeping the shingle seams outside 5 inches of each other in relation to the shingles in the previous and proceeding course when mixing the shingle sizes.

“After using HP42” format shingles on the test house, I’m going to start using them on all of my jobs because they make installation easier and faster and save me money because I don’t have to order as many bundles since they produce less waste,” Gowder states.

The roof qualifies for the Atlas Signature Select Roofing System warranty, which comes with a built-in extended protection period.

“The quality Atlas products, backed up by the Signature Select coverage, will protect this home for a long time,” Gowder says.

Metal Roof Provides Durability, Energy Efficiency for Florida Preschool

The Goddard School in Ponte Vedra Beach was constructed from an existing building

“Almost everything we do is kind of odd, weird and unique,” says Jay Maust, president and owner of Ford Roofing Systems Inc. in Ponte Vedra Beach, Fla. The company excels in high-end commercial and residential projects featuring metal, tile, slate and asphalt shingle roofing.

A recent metal roof installation in Ponte Vedra Beach was more straightforward than many of the company’s projects, notes Maust, but it has the aesthetics and architectural flair the company is known for. The project came to the company like all of the rest of the company’s jobs do: as a referral from an existing customer.

When the relative of a previous residential roof customer decided to completely gut, renovate and expand a building to put up a teaching preschool known as the Goddard School, Maust was called in to consult on the project, come up with a roof design and install it. The result was a standing seam metal roof that provides the durability and energy efficiency the school requires.

The existing shingle roof was torn down to the trusses, and any damaged trusses were replaced. After new wings were added, the building envelope was insulated with spray foam. New plywood decking was installed, and after the deck passed the county inspection, Maust dried the building in with Boral Tile Seal self-adhering underlayment. “It has great thermal properties to it,” he says. “In my opinion, it is the best peel and stick on the market.”

The next step was to install painted metal perimeter wall flashings for the metal roof system that would also serve as stops for the HardiePlank and stucco siding. “It not only provides waterproofing protection but creates a tie-in for our system,” says Maust. “We call it a receiver flashing. It provides a nice, straight line where the siding or stucco ends. There is typically blue plastic that covers the metal, and after the siding is installed, you just peel the plastic sheeting off, and any paint or residue that might have gotten on the metal is peeled off with the plastic. And the end you have a beautiful piece of metal that enhances the look of the building—and it’s a water barrier.”

The standing seam roof was manufactured by Metal Sales Inc. On jobs such as this one, the project superintendent typically measures the roof by hand and prepares a cut list for the manufacturer. Metal Sales shipped the finished panels to the site, including 24-gauge galvalume panels painted in Kynar Silver Metallic, drip edge, hip and ridge panels, and headwall flashing.

Precise Execution

Since the front entryway was still under construction, roofing crews began at the back of the building and worked their way forward. One hurdle was formed by the addition of a back wing, which had a primary support beam that intruded on a designed valley. Since the support could not be moved, Maust decided to change the slope of valley to avoid the potential eyesore.

Architectural details included shed dormers over the doorways and windows, as well as gable dormers with false louvers.

Proper placement of penetrations on metal roofs is critical, notes Maust, and the company takes pains to ensure that penetrations are kept to a minimum and are properly designed and executed. Crews make sure plumbing stacks are in the center of a panel and don’t interfere with the ribs. When plumbers rough in the stacks, roofing crews make sure the last section of pipe can be rotated to ensure it is in the center of a panel before the final cuts are made. “We make them go through this extra step,” Maust says. “If they won’t do it or can’t do it, we’ll do it for them.”

Coordinating work with representatives of other trades on the project was difficult, but it is necessary part of the process, according to Maust. Ford Roofing workers made sure to be on hand to assist framers, as well as contractors installing siding, stucco, fascia and HVAC equipment. “That is our roof, and we don’t want anyone else walking on it, period,” Maust says. “We’ll install weather vanes, cupolas—whatever’s going up there.”

The company built a curb for one of the HVAC fan units, and flashed in another that had a factory-installed curb to ensure they looked identical. “We went up there and sealed it in and flashed it,” Maust notes. “We made it look like it was part of the roof.”

For those forced to walk on the panels, rituals include knocking boots on the ladder and wiping the soles with a towel to ensure no sand or grit could possibly mar the finish. “We use foam tubes on our ladders so we don’t scratch the paint,” Maust explains. “It’s a learned process, and we’ve learned a lot of things over the years.”

Safety is always the top priority on every project. “On steep–slope jobs like this one, everyone wears harnesses and is tied off to their own bracket, which is properly attached to a truss,” Maust notes. “We are always checking on each other. Sometimes it’s hard to see if someone is tied off when they are on the top of the roof, so we developed this little motion where someone on the ground will make a hand gesture, and the person on the roof will pull up his safety line to demonstrate they are tied off.”

The installation on this project went like clockwork, according to Maust. “I’ve been doing this since I was 14,” he says. “The key is logistics. Is there stress sometimes? Absolutely. You just have to pace yourself.”

Maust is detail-driven, but he realizes it’s people who must execute the error-free, eye-catching projects that generate referrals. “Success comes from having guys in the field that care,” he says. “They understand very clearly that if they do a good job, this job is going to lead to another job. They get that. I also get that.”

The key is to not only build strong roofs but strong relationships. “I’m a very social person when it comes to my homeowners and my contractors,” Maust says. “If I’m working for a contractor, I want to meet the homeowner and help them select their tile. I want my reps, my builders, my homeowners to embrace a project together. I want everybody to know everybody. You develop these friendships and relationships, and that’s where great projects and great referrals come from.”

“That’s how I get my work,” Maust concluded. “All of my projects come to us through word of mouth. I’ve never placed an ad.”

The design for the metal roof on Logan High School called for panels on one side of the roof to measure more than 160 feet. That posed logistical problems, to be sure, but the project proved there’s more than one way to deliver roof panels.

Morin, a Kingspan Group Company, recently introduced an onsite roll-forming process that runs panels to the eaves, where they are gathered and stacked for installation. Logan High School in Russellville, Ky., was the first project that put the method to the test. Panels on one side of the roof were 46 feet long, while panels on the other side measured 161 feet, 2 inches in length.

According to the company, the on-site process offers the benefit of producing panels of almost any length without lapping them. This is especially useful when restrictions on the length of delivery trucks and their loads do not allow for panels to be delivered via truck.

On this project, 89,000 square feet of SymmeTry Roof Series panels in Regal White were installed. “For the longer panels, we had 11 men on the roof,” says Basil Slagle, production manager and roll former operator for Morin. “We also had three separate scissor lifts between the roll former and the eave, with men on them to guide the panels to the roof because that’s as close as we could get with the roll former.”

The SymmeTry Roof Series is a mechanically seamed structural roof system that is both symmetrical and hydrostatic by design. Slagle produced 18-inch wide panels with 2 1/2-inch legs from the 22-gauge, pre-painted Galvalume.

The start of the project was delayed by heavy rains, notes Slagle. “And that Kentucky red clay, if you’d walk on it wet, you’d sink into the clay up to your shin. They had trucks with four-foot tires getting stuck in the wet clay.”

Tough Field Conditions

When the rain stopped, Slagle got to the jobsite on a Monday and realized he would not be able to drive his 10-ton vehicle into place. “They had to build us a 300-foot gravel road so we could pull the machine into place, get it where we needed it to be,” he says. “We finally got set up that Thursday morning.”

Eastern Corp. installed the roof system

Once the roll former was in place—about 100 feet from the roof eaves—the three scissor lifts were rolled into place in line between the roll former and the roof edge. Slagle then ran a “sacrifice panel” to use as a bridge, of sorts, from the roll former to the roof. Panels going on to the roof would slide across the sacrificial panel to the roof, where crew members would carry them to a staging spot on the roof. The sacrificial panel, almost 100 feet long, was eventually recycled.

Slagle ran the shorter panels first so crew members could haul them across the ridge to the opposite side of the building. Then the longer panels were produced and set up on the near side of the building. The Regal White panels were all covered with plastic film to protect them from the red clay on the boots of the installers, who had to walk on the panels to install the batten over the seams. After the battens were installed and seamed, the plastic film was removed. (Failure to remove the plastic film in a timely fashion will eventually lead to damage on the panels when the film is removed.)

“The installation went great,” says Nancy Mullins, senior project manager for Eastern Corp., of Norcross, Ga. “We had anywhere from 12-17 crew members at the site at a given time. The challenges were the logistical hurdles like getting the scissor lifts in place and getting the panels to the roof and stacking them.

“We install all the panels and then come back to install the seam cap and do the seaming. We always wait to make sure everything is where it needs to be, in regard to any penetrations. We really had no issues.”

After the panels were in place, the battens were installed and seamed around the 2 1/2-inch legs of each pan. The battens were cut to 46 feet to match the panel length for the shorter roof. To batten and seam the 161-plus foot panels, the battens were cut to 81 feet and lapped near the center. Slagle ran panels for four buildings at the school, one attached to the main school building and three outbuildings still under construction.

Eastern also installed 1,100 linear feet of a snow retention system, the iBeam from Sno Gem. The iBeam is installed near the eaves on both sides of the roof, with the longer panels hosting a second row nearer the center of the roof.

North Carolina Middle School Generates More Energy Than It Uses

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.”
