Re-roofing sports and entertainment venues presents its own set of challenges. Sports arenas usually host concerts and other events, so scheduling and logistics can be difficult. Quicken Loans Arena in Cleveland — also known as “The Q” — is home to the Cleveland Cavaliers of the NBA, and it hosts some 200 other diverse events every year, including concerts and conventions. In 2015, realizing the roof was reaching the end of its useful life, the owners looked for advice on their next move. A team of roofing professionals recommended a roof restoration system that would provide the protection and recreate the aesthetics of the original roof — and keep disruption to the facility at a minimum.

Ohio companies stepping up to help the home team included architect Osborn Engineering, headquartered in Cleveland; roof consultant Adam Bradley Enterprises of Chagrin Falls; roofing manufacturer Tremco Roofing and Building Maintenance, headquartered in Beachwood; and roofing contractor Warren Roofing & Insulating Co., located in Walton Hills. After comprehensive testing revealed that more than 90 percent of the roof could be restored, they developed a plan to clean, repair and completely restore the 170,000-square-foot main roof of Quicken Loans Arena using a liquid-applied system from Tremco Roofing.

John Vetrovsky of Warren Roofing and Joe Slattery of Tremco Roofing shared their insights on the project with Roofing magazine. Both men were brought in during the planning stages of the project and saw it through to completion. “We were helping to budget the project with Adam Bradley and Osborn Engineering,” notes Vetrovsky. “They were asking about a few different systems, and the Tremco system was the best fit for the project.”

Warren Roofing has served the greater Cleveland and Akron area since 1922, and Tremco’s roots in northeast Ohio go back to 1928. Warren Roofing served as the general contractor and roofing contractor on the project. The scope of work included updates to the lightning protection system, the safety cable system, and the heat trace system used to melt snow in the gutters.

Repairing the Existing Roof

The existing system was the structure’s original roof. It was 24 years old, and consisted of a mechanically attached hypalon membrane over two layers of polyisocyanurate insulation totaling 3 inches. The roof membrane was showing some wear, and sections had sustained damage from an interesting source: fireworks from nearby Progressive Field, home of the Cleveland Indians, launched after the Indians hit home runs. After the damage was detected, the team changed the direction the fireworks were launched, and the problem ended.

Despite the damage, visual analysis and a nuclear roof moisture test using a Troxler meter confirmed the roof was an excellent candidate for restoration. “There was some wet insulation and warped insulation, and we marked off those areas that had to be replaced,” notes Slattery. “It was a small fraction of the total job.”

Crews from Warren Roofing removed and replaced the damaged insulation, cutting through the membrane all the way down to the existing 6-mil vapor barrier on the deck. “All of that insulation had to be stair-stepped back so we could properly lap in the new material,” Vetrovsky says. “We got rid of all of the damaged insulation, and we repaired the vapor barrier. Then we staggered the two new layers of insulation, matching the existing thickness.”

Where possible, the existing membrane was pulled back and glued into place. In sections where new membrane was needed, crews adhered pieces of EPDM.

The plan specified adding the fasteners in the existing roof and any repaired sections before the coating system was applied. Tremco Roofing conducted uplift testing through Trinity ERD to ensure the results met or exceeded the specified design. “There was a significant upgrade to the fastening,” Vetrovsky says. “Because of the shape of the building, the perimeter enhancement was probably the greatest I’ve ever seen.”

Screws and 3-inch plates were used. In the field, the minimum was 4 feet on center, 12 inches apart. In the perimeter, fasteners were installed 2 feet on center, 8 inches apart. “It worked out nicely because the fastening ended up in the middle of the sheet, and now the sheet has fasteners that are original at the seam, and a foot or two over, there is a row of new fasteners,” notes Vetrovsky.

Cleaning Up

Prior to the fasteners being installed, the membrane was cleaned by crews from Tremco Roofing using the company’s RoofTec system. “We cleaned the membrane no more than 30 days ahead of what Warren Roofing was doing,” notes Slattery. “We had to mobilize at least three times to clean the roof so the time elapsed would never be more than 30 days.”

The three-step restoration process consists of a primer, a base coat with a fiberglass mat embedded in it, and a topcoat. Here, crews embed the fiberglass mat in the base coat. Photos: Tremco Roofing and Building Maintenance

The cleaning solution is applied using a custom-designed tool that looks like a floor polisher. It has a 2-foot diameter head that spins to clean the surface and a vacuum that recaptures the water, which is returned via hoses to a truck so contaminated waste water, environmental pollutants and high-pH cleaning solvents can be filtered out. “All of that water goes back into the sanitary system after it’s filtered,” Slattery explains. “It does not go into the sewer system.”

“It’s very fast, it’s very effective, and it’s very efficient because you can easily see the areas that have been cleaned,” notes Vetrovsky. “With power washing, you don’t have any way to filter the water.”

The biggest challenge on the cleaning portion of the project was the arena’s sheer size. Approximately 500 feet of hoses were needed to supply water and return it to the truck for filtering.

Cleaning of the substrate is a crucial step, according to Vetrovsky. “The system really does a nice job cleaning the membrane, and that is the key to any restoration project,” he says. “You’re only as good as the surface you’re applying it to.”

Applying the New Roof System

After the sections were cleaned, crews installed the liquid-applied AlphaGuard MT system. The three-step process consists of a primer, a base coat with a fiberglass mat embedded in it, and a topcoat. In this case, the primer was applied with rollers. “The area that we primed each morning was the section we would apply the first coat of AlphaGuard MT with the fiberglass mat that afternoon,” Vetrovsky says. “We did not prime ahead. We didn’t want to take the chance of dust adhering to the primer.”

The top coat was applied with both rollers and spray equipment. Photos: Tremco Roofing and Building Maintenance

Care had to be taken with the schedule to complete the work efficiently. “Once the base coat is on, you have 72 hours to apply the top coat,” Vetrovsky explains. “We would install the base coat and the fiberglass mat for two to three days to get a big enough area. The topcoat would go on faster because you’re not embedding any mesh into it. You really had to always keep an eye on the future weather to make sure you could get the topcoat on within the 72 hours.”

The topcoat was applied with both rollers and spray equipment. After the topcoat was applied, crews installed a second coat with sand embedded in it as a wear surface. Because of the roof’s curved surface, walk pads were not feasible, so the sand was used to provide additional traction for any workers conducting ongoing maintenance.

The sand was broadcast by hand and back-rolled into the coating to maintain a uniform appearance. “Part of this project was to make sure the sand looks uniform when it is visible from a blimp overhead,” notes Vetrovsky. “That was a difficult task, but the guys did a great job.”

The roof features three different finish colors, which were custom designed to match the roof’s original color scheme. The main roof is light gray, with black under the large LED sign. The sections over the wings are white, as are the 2-foot-wide stripes.

“They wanted black under the new LED sign so it would really show the letters nice and clear, even during the day,” says Vetrovsky. “We also put the white stripes back to match the roof’s original appearance. That was a challenge, to keep everything straight. It’s hard to chalk lines on a curve, but it came out nice. Everything matches what the original roof looks like.”

Penetrations for the sign included round posts that held the rails about 2-1/2 feet above the roof level. The liquid-applied membrane made coping with details easy, according to Vetrovsky. “The liquid membrane makes the flashing details all one piece with the roof system,” he says. “We removed the existing boot flashings so that we could seal directly to the conduit or steel posts.”

Gutters, Lightning Protection and Safety Systems

The large commercial gutters also needed to be refurbished. The gutters were 4 feet deep and 4 feet wide, and were outfitted with a cable snowmelt system, which had to be removed. “The gutters had a lot of damaged insulation, so material in the gutter sections was 100 percent torn off,” notes Vetrovsky.

After the roof surface was cleaned, the restoration system was applied. The three step process consists of a primer, a base coat with a fiberglass mat embedded in it, and a topcoat. Photos: Tremco Roofing and Building Maintenance

In the gutters, tapered insulation was installed, and a cover board — DensDeck from Georgia-Pacific — was added for increased durability. New EPDM membrane was installed and cleaned prior to the three-step coating application. New heat trace cable was also installed.

The lightning protection system also required repair, and close coordination with the subcontractors was critical. “The existing lightning protection had to be removed to apply the new roof system, but we couldn’t remove it 100 percent, because we still had to have an active lightning protection system for the building,” says Vetrovsky. “We rearranged the lightning system and installed new stanchions to try to eliminate as many horizontal lines as we could.”

During construction, key to the safety plan was a perimeter barrier system, which was installed by workers who were 100 percent tied off. After the system was in place, workers inside the barricades did not need to wear personal fall arrest systems. “The entire perimeter had a barricade system put on before any material was even loaded,” Vetrovsky says. The company makes its own barricade sections, which are anchored to the parapet walls and gravel stop edges and feature a downward leg for added support.

As part of the project, crews also installed permanent safety equipment. “There was an existing tie-off system out there, but it was not a certified system and we couldn’t use it,” Vetrovsky says. “We brought that to the owner’s attention and replaced it with a new certified tie-off system manufactured by Guardian Safety.”

Challenging Schedule

Progressive Field and the Quicken Loans Arena are right next to each other, and logistics and scheduling around the stadiums was difficult. Work began in 2016 and finished in 2017, and the demanding schedule was made even more difficult when both the Indians and the Cavaliers made deep runs into the playoffs. In 2016, the Cavs became NBA Champions. But it was the Indians making it to the 2016 World Series that posed bigger logistical problems for the re-roofing project.

“The first part of the schedule was the most difficult, as we had the get the black coating on the roof under the sign prior to the playoffs,” Vetrovsky says. The sign covered approximately 30,000 square feet of roof area, and it was difficult to access the roof surface beneath it. “Crews had to work on their hands and knees to apply the coating beneath the steel framing. That was towards the fall, when the weather started changing, and one of the biggest hurdles was just getting the roof dry in the morning. It got colder and colder as we got down to the wire, but we made our deadline for the work under the sign.”

The staging area was also limited, and the crane could only lift material to one section of the roof. Some material had to be moved by hand some 2,000 feet. “It was an awfully long walk from one end of that roof to the other,” Vetrovsky recalls.

Concerts and other events held during the construction cycle made the schedule even more challenging. “The most notable event was probably the Republican National Convention, which totally shut the site down for more than a week because of security,” notes Slattery.

Concerts usually necessitated loading in the early morning and clearing the staging area by 8 a.m., but usually work could continue during the day. “We had to do a lot of coordination to make sure we had what we needed to work the entire day and also not go against our commitment to the owner that we would not work past certain hours,” Vetrovsky says. “Many of the special events started after 7 p.m., so we would be long gone by then.”

Championship Caliber

The project was wrapped up earlier this year. Vetrovsky and Slattery agree that the system chosen was a great fit for this project for several reasons. With restoration, there is less noise, less disruption, and less equipment than with a re-roofing project, and the roof has a warranty for the next 20 years. The process also limits negative impact on the environment by preventing removal and disposal of the old roof system.

“The weight was also a factor,” notes Vetrovsky. “With the existing structure, there wasn’t a lot of room for a different type of roof system with heavy cover boards. This roof system was perfect because it doesn’t add a lot of weight.”

The coating also minimized installation time, notes Slattery. “The disruption of a roof replacement in a hospitality setting like that, where they need 250 days of revenue stream, restoration becomes a real attractive option,” he says. “I can’t think of one day where we really disrupted anything.”

Vetrovsky points to his talented crews as the key to meeting tough schedules with top-quality production “What we can offer is skilled labor,” he says. “We’re a union contractor and our guys are well trained. The harder, the better for us. We can handle projects that most other contractors won’t even put a number to — this project being one of those.”

He credits Adam Livingston, a third-generation foreman for Warren Roofing, for his work on the project.  “With his experience and attention to detail, we were able to complete this project on time, meet the expectations of the client and Tremco, and match the unique aesthetic requirements of the roof,” says Vetrovsky. “We have a lot of great employees who take pride in their work. Take all of that together, that’s why we can be successful on projects like the Quicken Loans Arena.”

The Cavaliers taking the NBA Championship during the project only added to the excitement. “It’s a great feather in our cap,” notes Slattery. “Restoration is a growing segment of the market. Instead of letting the clock run out on these roofs, if you catch them at the right time, it can be a phenomenal way to keep costs down and it’s good for the environment because it’s not adding waste to landfills.”

Expert Crew Is Called in for Copper Roof Restoration Project

The octagonal dome atop the Bradford County Courthouse has been a fixture on the Towanda, Pennsylvania, skyline for more than 120 years. It now shines brightly after being restored with copper panels as part of a $3 million renovation project.

Built in the Classical and Renaissance revival styles in 1898, the four-story courthouse was placed on the National Registry of Historic Places in 1987. The dome’s original roof tiles were recently replaced as part of the project, which also included the complete restoration of the structure’s main roof.

The Charles F. Evans Company Inc., the union division of Evans Roofing Company Inc., headquartered in Elmira, New York, has a long history of successfully tackling projects with historical significance. C&D Waterproofing Corp., the general contractor on the project, reached out to the firm for support assessing the roofing portion of the project. The two companies teamed up on the project, with C&D Waterproofing handling the masonry restoration work and Charles F. Evans Company installing the roof systems.

The roofing work consisted of two phases. Phase One, which began in April of 2016, involved replacing the deteriorated terracotta tiles on the dome with soldered flat seam copper panels. Phase Two, which began in April of 2017, involved installing batten seam copper roofing on main structure and new copper flashings, gutters and downspouts.

Safety First

Construction Manager Bill Burge of Charles F. Evans Company was thrilled to be part of this historic project. Before

concentrating on the installation details, he knew the company would focus on the top priority. “Safety is number one,” says Burge. “Safety comes before profits. Safety comes before everything. We always want to make sure we have the right safety plan going into the job, and throughout the job, we are maintaining that plan and working that plan. We want our guys to go home to their families at the end of the day, so that’s key for us.”

Burge worked as a union carpenter for 10 years before joining the company more than seven years ago. He found he had an affinity for sheet metal work. “The craftsmanship and quality goes hand in hand with carpentry,” Burge says. “Everything starts with the carpentry. You have to have your base perfect; otherwise, everything from there on out doesn’t work. Sheet metal is a finished product, typically, especially in our business, so things have to be done right. Things have to be done to the highest standard of quality, because that’s what people see.”

The dome was designed to be a showpiece, and Field Superintendent Brian Babcock and his crew of qualified union sheet metal mechanics knew they would be held to an exacting standard. “The key to this project and every project is our talented mechanics in the field,” Burge says. “Charles F. Evans Company is nothing without this talent—they deserve all of the credit.”

Around the Dome

Phase One began with the removal of the tiles on the dome. “The ceramic tile was laid over open steel purlins,” Burge notes.

“There was open framing with quarter-inch steel angle for the purlins, and each piece if tile was wired on. The removal process was fairly simple. You could actually lift up the bottom of the tile and snap it off.”

The removal work had to be done in sections and dried in every night. “One of the hardest things about this process was we had to install two layers of half-inch plywood over the steel purlins and anchor those down,” says Burge.

The plywood was attached to vertical two-by-fours, which were screwed into the purlins. The plywood was covered with one layer of Warrior 30-pound felt paper, Meadows Red Rosin Paper, and Grace Ultra High Temp underlayment in gutter areas.

The built-in gutter at the base of the dome was torn out and re-framed. The new gutter was wider and deeper according to the recommendation of Levine & Company Inc., the architect on the project. “We did everything to specification as Levine & Company drew it,” says Burge.

Once the cladding was completed on the gutter, the copper panels of the dome were installed. The 20-inch panels were made of 20-ounce, cold rolled copper, supplied by Revere Copper Products. Both the panels and cladding were fabricated in Charles F. Evans Company’s fabrication shop. The copper panels clip to each other and have a hem on four sides that clips

to the adjacent panel fastened to the deck. At the top of each panel, a hook clips off to the plywood, and the hook is covered by the panel directly above it.

Burge points out that the octagonal structure of the dome helped speed up the installation of the copper panels. “There are eight hips on the dome,” he notes. “Every section of the dome is like a piece of pie, basically, so we were able to start the panels in various locations. We didn’t have to start at one end and go around the dome. We could move around.”

Repairing the statue on the top of the dome was also part of the scope of work. “We soldered copper patches on any damage the statue had,” Burge says. “C&D Waterproofing completely cleaned and buffed the statue and applied a copper coating.”

Across the Roof

After the work on the dome was completed, work began on the main roof. The existing roof was removed down to the existing steel deck. The lower roof also had a built-in, copper-clad gutter that had to be removed and reconstructed. After

the gutter was completed, work on the main roof began. “After we completely cleaned the metal decking, we had to install a layer of Grace Ultra High Temp underlayment,” Burge recalls. “We then installed two-by-four wood sleepers, 2 feet on center.”

Crews installed 1.5 inches of polyiso insulation between the two-by-fours, followed by another 1.5-inch layer of polyiso. Pieces of 5/8-inch plywood were then screwed down to the sleepers. The plywood received 30-pound felt, and the battens were installed 20 inches on center. The seams were completed using a custom-designed mechanical seamer manufactured by Roll Former Corp.

Installation of the 12,000 square feet of copper panels went smoothly, but where panels met the dome, details were tricky. “Everything is pitched, and the dome has eight different sections sitting right in the center of the structure,” Burge explains. “A lot of time and energy went into fabricating and installing custom flashing pieces at the base of the dome.”

The Safety Plan

A scaffolding system was the key to the safety plan for both phases of the project. “For Phase One, we had to remove a portion of the roofing system and put down some plywood on top of the existing roofing in order to build a scaffold to access the dome,” Burge says.

This photo shows the main roof before restoration work began. Photos: Charles F. Evans Roofing Company Inc.

Scaffolding was constructed to the eave edge of the copper dome, allowing the gutter to be removed. Ladders were used to access the dome and personal fall arrest systems were attached into HitchClips from Safety Anchor Fall Equipment, LLC, which served as individual anchor points. “We continued that process as we went up, using ladder jacks,” says Burge. “We continued with that plan, and never deviated.”

After Phase One was completed, the scaffolding was removed, and another scaffolding system was installed around the entire lower roof. Phase Two required planks and pre-engineered guardrails at the eave and rake edges. “Part of process of installing this roof included installing new safety anchors at various locations, and as we finished up, we were able to use those anchors as tie-off points,” Burge points out.

Phase Two is scheduled for completion in early November, and Burge has high praise for everyone involved with the project. “Levine & Co. Inc. is the architecture firm on the project,” he says. “We didn’t deter from any details developed. They drove this thing. We have worked with them on a great many projects in the past, and we have a great comfort level with them.”

The masonry and roofing work had to be well coordinated. “C&D Masonry & Waterproofing progressed ahead of us with items that we needed to be done, and then came back behind us to mortar all of the counter flashings back into the dome,” Burge says. “They were right there with us every step of the way.”

Finding the right combination of workers for this project was crucial, according to Burge. “We had one of our best crews on this project for a reason,” he says. “This project was led by Brian Babcock of Sheet Metal Local 112, and he was essential in putting this whole thing together. He’s been with Charles F. Evans Company for 20 years, and his leadership and focus is the reason this project is going to be successful.”

Ornate sheet metal work is rare these days, but the art is not lost at Charles F. Evans Company. “We’ve been doing this work for 60-plus years,” Burge says. “This knowledge and this workmanship has been handed down generation after generation. We wouldn’t have taken on this project if we didn’t have the confidence in our employees that we do.”

Historic restoration projects are becoming an increasingly bigger chunk of the company’s portfolio, notes Burge. “We do a lot of work with older universities and businesses that have these types of buildings,” he says. “A lot of buildings need this type of work, and it’s a trade not everyone else has. This is a craft that takes years to master. We harness that, we build from within, and we bring in young guys and teach them how to do it the right way. We have a great mix of people ages 23 up to 60, and it’s learned, it’s taught, and it’s preached.”

Burge is hopeful the new roof will last at least as long as its predecessor. “This is the one thing that makes Charles F. Evans Company special to me: the fact that what we do from an architectural sheet metal standpoint, from a slate, copper, tile roof standpoint—these roofs will last 100, 150 years, and it is artwork,” he says. “The fact that you’re a part of something that’s been around since the turn of the last century—to me it doesn’t get any better than that.”

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.”

Students Take the Lead on Roof Restoration Project

Thomas Portaro is the owner of NTEC Systems, a company headquartered in Alpharetta, Ga., that specializes in roof restoration projects. Portaro owns the company, but on a recent project on the campus of Georgia Tech, it was definitely the college students who were in charge.

Portaro was contacted by students who were researching different roof systems as part of a class project. Members of the class had been tasked to come up with ways to reduce carbon dioxide emissions on the school’s Atlanta campus.

Students were exploring all sorts of environmentally friendly building systems, including LED lighting and HVAC equipment. One group of students explored various building envelope modifications, eventually narrowing their focus to the roof system.

“This particular group of students showed the school and their professors how they were going to reduce carbon emissions and the energy footprint of the O. Lamar Allen Sustainable Education Building by doing a roof restoration,” Portaro said.

Portaro, a Georgia Tech graduate, was contacted by the group to provide some insights on the potential benefits of coatings. “I was asked to come down to the campus and give a brief lecture on the values of roof restorations, the types of coatings I was familiar with, how they were applied, and how they could restore this particular roof.

The building was built in 1998, and its roof was the original modified bitumen system. When students learned how a cool roof system would extend the life of the roof and save on utility costs for the building, they not only presented their findings to their professors but officials at the university. The school ultimately decided to fund the project.

NTEC Systems completed the installation of a high-solids silicone roof coating manufactured by GE. “The students pioneered all of this,” Portaro says. “This is an amazing group of kids. To be invited back to my alma mater and to execute this project really hit a chord with me. The project really worked out well, and it was really cool because I got a check from Georgia Tech. Think about all of the money I’ve paid them over the years. It was nice to get a little bit of that money back.”

Practical Application

One key concern for the university was achieving a 20-year warranty, so the first step was to ensure that the existing roof was compatible with the system. “One of the big value adds of GE Performance Coatings is that their tech side is very strong,” Portaro notes. “GE has great specifications, and they make it pretty simple for me as an engineer to go up and evaluate a roof and make sure it meets certain criteria. You have to evaluate each roof to ensure it meets the criteria for a restoration.”

“A great phrase—and I forget who coined it—is, ‘We do roof restorations, not roof resurrections,’” Portaro continues. “The existing roof has to be in a restorable condition.”

Infrared analysis was conducted to ensure the roof system was dry. Some minor repairs were needed, but overall the modified roof was in good shape. It was cleaned with pressure washer and primed with an asphalt bleed-blocker from GE Performance Coatings. NTEC crews then spray-applied two coats of GE Enduris 3502 high-solids silicone roof coating to a minimum thickness of 40 mils when dry. The system forms a monolithic coating that is self-flashing. “We detailed it all out, the inspectors inspected it, and at the end of the day it was all done, the 20-year warranty was in place, and everyone was happy,” Portaro says.

He points out that the GE silicone coatings rarely require a primer. “This is the only type of roof that requires a primer, and the only reason it does is that asphalts tend to bleed through silicones and can tobacco-stain them,” he notes. “It’s aesthetics—that’s it. The GE system is one of our ‘tried and trues’ in part because for 99 percent of the roofs we do, it’s a primerless system. So, we save that step, which saves us time and ultimately saves the owner money.”

NTEC Systems excels at large, high-volume jobs, and the company is always looking for tools to make it more productive. “We are highly automated here,” Portaro says. “That’s our strength. It’s what we do. We have the ability to do a ton of square footage in a short period of time because we have the latest and greatest machinery. We’ve actually created our own method of going from ground to roof and getting coatings spray applied.”

The company has modified some industrial machinery to move large volumes of high-solids silicone under control, according to Portaro. “Now, it’s not robotics,” he explains. “It still takes artistry. It still takes an expert pulling the trigger. We have guys that are very talented, and now the machinery is keeping up. We can do four or five times as much work in a day as we used to do just a few years ago. Our production levels have blown up.”

A Learning Experience

One of the challenges on this project was taking the time to use the application as a teaching tool. “The students were there the entire time,” Portaro remembers. “We were surrounded by some of the smartest people in the world. I’ve never had so many managers on a project in my life. These students brought a passion to the building industry like you’ve never seen before. They believe they are going to change the world, and they probably will.”

Portaro also shared his passion for environmentally friendly roof systems. The students apparently took that message to heart. “These kids are something special,” he says. “They went to Washington, D.C., to present this project to the Congress of the United States. These kids weren’t happy with just affecting one building on the campus of Georgia Tech. They wanted to share the story. This project got national recognition. I was really proud of these kids, who I met for the first time on this project. My hat’s off to them.”

Portaro has installed a lot of cool roofs, but the Georgia Tech project was special. “This was certainly the coolest project I’ve ever done,” he says.

Roof Restoration Project Keeps Rehab Facility Operating

Skyline Roof Restoration

Bill Steeves (left) and Steve Broda launched Skyline Roof Restoration, a company that specializes in restoring roofs with coatings.

Rehabilitation facilities help their patients stay healthy. Keeping roofs healthy is another matter.

When the roof at a rehabilitation center in Colorado was reaching the end of its service life, roofing contractor Bill Steeves recognized it was the perfect candidate for roof restoration project. Steeves is the president of Skyline Roof Restoration Inc., based in Frederick, Colo. The company specializes in roof coatings. It was launched last year by Steeves and his partner, Steve Broda. Broda is the founder of Skyline Roofing Inc., a full-service commercial roof contracting firm, also located in Frederick, where both men have worked since 2006.

“We formed Skyline Roof Restoration as a vehicle to promote restoring roofs with coatings,” Steeves says. “We have both been involved with various coating projects in the past and wanted to offer our expertise to clients where restoration is their most prudent option.”

In the Denver area, the coatings market is booming in part due to changes in local energy codes, notes Broda. Several municipalities have mandated with that a roof tear-off and replacement, the R-values in the roof have to be brought up to those for new construction. “It was becoming unaffordable for some people to do total roof replacement and upgrade to R-30 or R-38,” Broda says. “We needed another tool to provide them with a roofing option that was economical and did not force them to add the extra R-value to their roof systems.”

In many cases, coating an existing membrane roof can be an excellent option. “It can save the customers a lot of money compared to a roof replacement, and depending on the system and the thickness, we can offer a 20-year NDL warranty,” Broda notes.

Skyline Roof Restoration

The Centre Avenue Health & Rehab project encompassed 21,863 square feet of low-slope roof on 10 separate roof levels. The low-slope sections were surrounded by a standing seam metal roof.

According to Steeves and Broda, the key to the success of a roof restoration is making sure the underlying substrate is a good candidate for the coating. Skyline Roof Restoration will only authorize a coating project if it is the best option for the facility. “Steve and I have a combined 77 years of experience in commercial roofing, and there are very few scenarios we have not run across,” Steeves says. “We have both built very strong commercial companies based on return customers and referrals. We both really care about the final product, value to our customers, and the relationships we have developed over the years.”

The Diagnosis

Steeves had a hunch that the roof at the Centre Avenue Health & Rehab facility in Fort Collins might be reaching the end of its life span. “We have been doing all of the roofing work for Columbine Health Systems, the owner of Centre Avenue Health & Rehab, for more than seven years and have developed a great working relationship with the owner,” he says. “We had never been called to Centre Avenue for any leaks, but I knew the building was about 18 years old.”

Steeves suggested it was time to conduct a roof inspection at Centre Avenue but was told to wait. Sure enough, the next time it rained, a leak was detected. When Steeves met his repair crew on the site, he noticed that the fully adhered EPDM roof system on the flat roof sections was just beginning to exhibit signs of oxidation. A few stress fractures were visible in the membrane. “It was a perfect candidate for a roof restoration,” he says.

In a meeting with the owner, Steeves suggested the application of a high-solids silicone restoration system from GE Momentive. “I explained that the restoration process would, in effect, freeze the aging process of the EPDM by protecting it from further UV degradation,” Steeves says. “I had also, prior to our meeting, completed some research and found out that the local power company was offering a rebate for any Energy Star-qualified roof covering, which further reduced his total capital outlay.”

When Steeves detailed the costs involved with the coating project as opposed to a tear-off and replacement, the owner gave him the go ahead on the roof restoration plan and opted for a 15-year NDL warranty.

Broda and Steeves note that there are cases in which the existing roof is too far degraded to work well with a coating, and in those cases, the only viable option is a roof replacement. The silicone coating can be used on membranes including EPDM, TPO, PVC, modified bitumen and smooth built-up roofs, as well as metal. “It works with all types of membranes, but you have to catch these roofs before the end of their serviceable life,” says Broda. “They have to have some life left in them to coat them. If we are not comfortable putting a coating on a roof, we won’t do it.”

Often all that is needed is minor repair of wall flashings, curb flashings and penetrations. Wet insulation is another problem to look out for. “We’ll do an infrared scan of the roof before we coat it to make sure we don’t have any wet insulation in there.”

Every proposal is also contingent on a successful adhesion test. A sample area is set up and a pullout test is conducted to determine if the product will adhere well.
