Lifelong Learning

The depth and diversity of continuing education options in the roofing industry continues to amaze me. Courses sponsored by industry associations, manufacturers, trade shows and contractors abound. In the year of the pandemic, more online options have emerged, and webinars and videos have taken center stage.

In an industry that is constantly evolving, roofing professionals need to keep up with changes in technology and product development. They also have to stay on top of codes and regulations, and make sure jobsites are safe and work is profitable. Running a business is no small task, and lifelong learning is a necessary part of the process.

Continuing education can be tough to fit into a busy schedule. It can be a grind. It’s easy to forget that learning can also be a rewarding experience that can pay big dividends down the road.

In the “Business Sense” article in this issue, Paul Scelsi details the numerous benefits of continuous education as enumerated by Kevin Marcano, owner of Marcano Roofing in Salem, Oregon. Marcano views ongoing training as the best investment you can make in yourself and your business.

“If you want to be the best in this industry, in your business or in your personal life, then continuous education is crucial,” Marcano says. “Being a business owner is challenging in the ever-changing roofing industry, in which each decade brings new building products, practices and concepts. If you don’t decide to incorporate continuous education into your process you become a dinosaur; and it’s not a matter of if but when your process becomes extinct. If you want to stand out, if you want to be memorable and leave a legacy, continuous education must be part of your process.”

If you want to jump into continuing education options, check out the on-demand sessions of the IRE Virtual event. Check out the webinars and educational sessions available from the manufacturers you work with, as well as industry associations including the NRCA. The NRCA ProCertification program is a big step in formalizing education and training in the field. Make it the next step in a never-ending learning process.

On-demand video sessions are easier to fit into your schedule than an in-person class, but it still can be tough to do. For those struggling to find the time, Marcano offers these words of wisdom: “Don’t let your thriving business culture become numb to the threat of the most debilitating sickness a company can become diagnosed with: complacency.”

Roofing Contractor Flexes its Muscles at Kissing Tree San Marcos

The amenities campus at the Kissing Tree includes swimming pools, a fitness center, pickleball courts, a golf course, bocce ball courts, horseshoe pits and a beer garden. Texas Traditions Roofing

Kissing Tree is a 1,300-acre gated community for residents 55 and older in San Marcos, Texas. Its centerpiece is The Mix — a 20-acre activity campus with amenities for residents including indoor and outdoor swimming pools, a fitness center, pickleball courts, a golf course, bocce ball courts, horseshoe pits, and a beer garden.

Texas Traditions Roofing tackled a variety of work on the project, including metal roofing, single-ply roofing, and wall panels for the Fitness Center and Swim Center. They also provided roofing for the Comfort Center, pool cabanas, and a covered walkway. Challenges on the project included the multiple scopes of work, as well adapting to an ever-changing schedule and working around multiple trades on a busy jobsite.

As work progressed under the general contractor, BEC Austin, crews from Texas Traditions were ready to jump in as needed. “The project consisted of multiple buildings, so we just rolled as they were ready,” recalls Michael Pickel, vice president of Texas Traditions Roofing. “When they were ready for us to do the TPO at the Fitness Center, we got started right away. A few weeks later, they were ready for metal, and we ran our metal guys out there. Then we went over to the next building, whether it was the indoor pool or the Comfort Center, as they were ready. There were multiple trades working with the general contractor, so we made sure that we were meeting their expectations and being out there when we needed to be out there so they could open on time.”

The Fitness Center

Work on the Fitness Center began with the section of TPO roof in the area that supported the HVAC units. Crews mechanically attached the two layers of 2.2 inch polyiso insulation, along with tapered insulation to provide proper drainage. “We gang fastened all of that together with half-inch DensDeck and then adhered the 60-mil GAF EverGuard TPO over that,” notes Pickel. “We installed walkway pads for the HVAC units and terminated everything.”

The design featured screens designed to shield the HVAC units from view. When the roofing work began, the base of the framing had already been installed through the deck, and crews for Texas Traditions set up pourable pitch pockets and boots. The screens were installed after the roofing work was completed.

Texas Traditions Roofing installed approximately 10,000 square feet of metal roofing, 5,000 square feet of TPO, and 2,500 square feet of Corten metal wall panels.

The roof was bordered by a very low parapet, so the safety plan included flags at the perimeter as well as personal fall arrest equipment. “It’s not a huge, wide-open building, so it was not ideal from a safety perspective,” Pickel recalls. “You’re going to have times where it’s crowded up there. Crew members had to be tied off at the perimeter and while installing the coping cap.”

The low-slope area is intersected by a large plane of sloped metal roofing. The metal roof was comprised of Sheffield Metals 1-1/2-inch mechanical lock panels, which were installed over Sharkskin High-Temp Ice and Water Shield and the wood deck. “On the fitness center, we rolled all metal on site,” Pickel says. “There were multiple trips for metal for each building, but the nice thing with the Fitness Center was it was pretty straightforward. We just ran the panels out to length and installed them. Later we came back and installed the awnings on the first floor as well, using the same metal.”

The Indoor Pool

The Swim Center also featured a TPO roof where the HVAC units were installed, as well as a large metal roof. “The indoor pool was fun,” Pickel says. “The TPO section was similar to the Fitness Center — tight space, low parapet — but even smaller. There was a lot of detail work for such a small area. The difference was that the roof was structurally sloped from front to back, so we didn’t have to install tapered insulation.”

Pool buildings have crucial considerations, notes Pickel. “When you are dealing with a pool —an indoor pool especially — you’ve got different concerns that you’re worried about, including condensation and chlorination. We’re thinking through all of those items when we are talking with the GC to minimize any issues with condensation in the future.”

The metal roof on the Swim Center is comprised of 1.5-inch mechanical seam panels from Sheffield Metals that are 110 feet long.

Consultations with the architect and waterproofing contractor were designed to ensure the structure could handle high levels of moisture. “A lot of it was making sure everyone understood what was going on below the deck,” Pickel explains. “We had to make sure they were waterproofing the interior — the understructure of the facility. From a roofing standpoint, you don’t want water to seep up through the ceiling and cause issues with the underside of the panels. We had to make sure the facility was good and watertight both inside and outside.”

After the TPO section was completed, crews moved on to the metal roof. “The metal panels were 110 feet long,” Pickel says. “We ran one panel all the way down because we didn’t want any breaks. It was only one story high, but getting those panels up to the roof without bending or scratching them was a challenge.”

Ultimately crews implemented a three-man pulley system to lift the panels to the roof. “We moved one long panel at a time, nice and slow,” he says. “We had three or four guys up top to maneuver the panels into position. It’s not fun carrying a 110-foot panels about 90 feet  from one end to the other, but you do what you’ve got to do.”

Poolside

Texas Traditions also installed a TPO roof on the Comfort Center (an outdoor restroom) and metal roofs on the open pool cabanas. “The cabanas were added afterwards,” says Pickel. “They originally wanted those roofs to be made from corrugated panels, but we told them it would look better if they went with the same panel all of the way across the board. They agreed and went with the 1 1/2-inch mechanical lock panels and half-round gutters to go with them to give it a clean, professional look.”

Crews also roofed the covered walkway with translucent KODA XT polycarbonate panels. “It was something we hadn’t done before, which was kind of fun,” Pickel says. “It’s an engineered panel — fully custom.”

Since it was the company’s first experience with the system, the manufacturer was on site to provide training and answer questions throughout the process. “There was good communication through and through with the manufacturer,” notes Pickel.

Wall Panels

Work didn’t stop at the roof. Texas Traditions also installed Corten A606 wall panels in Rust color on the Swim Center and Fitness Center. The panels were custom fabricated at the jobsite. “We actually made those out of flat sheets and bent everything on site. They were about 3 feet wide and 4 or 5 feet long. We literally cut a sheet, bent it up, cut the sides, and installed the panels. Each panel interlocked and interconnected.”

Texas Traditions is proud of its multifaceted work at Kissing Tree. “This project showcases what we are able to do,” Pickel says. “We handled multiple aspects of the project, from TPO, to metal roofs, to wall panels, to walkways. Our crews have the ability to tackle everything from a standard, cut-and-dried residential or commercial replacement, all the way to cut-up, detailed, custom metal roofs and metal wall panels.”

Challenges such as working with other trades and a shifting schedule are all part of any new construction project. “You’ve got to be able to cope with delays and last-minute changes,” Pickel says. “You just have to be willing to work with other people. Some roofers don’t like to do that, but it’s the nature of the beast. If you want to do new construction, you have to work as a team. At the same time, you’ve got to own your section, own your responsibilities. You can make other guys’ lives easier, or you can make them way more difficult. You want to be a contractor that is good to work with from the GC’s standpoint, and also good to work with from the standpoint of other trades.”

Solving the Puzzle

There’s a special feeling that comes with solving an intricate puzzle. That flash of insight when you spot a solution can be very satisfying. It’s even more satisfying if everyone else missed it.

Re-roofing applications can pose some of the toughest puzzles around. Everything has to fit together perfectly. These real-life puzzles have more than one solution, and sometimes an experienced contractor can come up with an answer that no one else envisioned. When that solution is more durable, easier to install, and less expensive than the other alternatives, that’s a true win-win-win scenario.

I talked to two contractors for this issue who recently hit that trifecta: Bill Devine of Coatings Application & Waterproofing Co. and Doug Claxton of The Solar Revolution.

When the standing seam metal roof on the Ritz-Carlton Coconut Grove in Miami had to be replaced, proposals for replacing the metal roof required large construction cranes to be mounted near the entrance of the property for months, causing disruptions for hotel guests.

Devine, area manager for Coatings Application & Waterproofing Co., proposed installing a PVC system that looked like a standing seam metal roof instead. He asserted it would be more cost-effective and last longer than metal in the harsh oceanside environment. Construction would also be less intrusive for hotel guests because it would not require a crane — Devine knew he could bring everything up and down using the service elevator.

Claxton, principal and founder of The Solar Revolution, had been contacted by the Boulder Jewish Community Center to explore rooftop photovoltaics when the facility was built, but unfortunately, the budget didn’t allow it at the time. Claxton notified board members when the city and county made grants available to help nonprofit organizations add solar power.

When the first phase of the solar project was put out for bid, all the other contractors focused on sections of flat roofing for the PV system. Claxton had a better idea. He suggested installing the array on the standing seam metal roof of the gymnasium. Thanks to an innovative attachment system, mounting solar modules on the curved metal roof would be easier and less expensive than other alternatives. And, unlike the solar array on the flat roof, it would also be highly visible, helping the Jewish Community Center use solar power as an educational tool. Like a giant billboard, the solar array also helps spread the word about the grant process.

You don’t hit home runs like this in business every day. When you do, you should savor them.

High-End Residence Gets New Slate and Copper Roof After a Tornado

After this home’s roof was damaged by a tornado, Precision Construction installed 22,700 square feet of slate and 3,700 square feet of copper standing seam panels. Precision Construction & Roofing

The Preston Hollow neighborhood in North Dallas is renowned for its high-end homes, but after a tornado tore through it in November 2019, many of them were left with substantial roof damage. Precision Construction & Roofing, headquartered in North Richland Hills, Texas, was tapped to replace almost 27,000 square feet of slate and copper roofing on one residence.

According to CEO Eric Hunter, Precision Construction was perfect for the job. The company specializes in complex projects and storm restoration work. “Our focus when we started the company 12 years ago was high-end residential, mainly historic,” he says, “We do all types of roofing but focus on slate, tile and copper. We’re doing more and more commercial work as the years go by, and we’re planning to launch a commercial division, so we’ll be doing a lot more commercial work in the future.”

The company is well-known for its work on historic homes featuring Ludowici tile. “We’re the Ludowici Contractor of the Year for four years running, and we’ve won Ludowici Roof of the Year for five years in a row,” notes Hunter.

This slate and copper roof was one of the biggest residential projects the company has ever tackled. “It’s a monster,” says Hunter,

The slate roof was a blend of North County Black Slate and Vermont Unfading Green.

The existing roof was comprised of copper panels and Chinese slate, which was installed by the home builder. “We tore that off — or I should say the tornado tore a lot of it off for us,” Hunter recalls. “It had extensive tornado damage. All that copper standing seam you see on the roof at the top was completely gone.”

One of the company’s salesman found a section of the copper roof draped over a power line two blocks away.

Precision dried in the damaged roof and completed the roof replacement as part of an insurance claim. After the claim was approved and slate arrived, the actual installation took about six weeks from start to finish.

One crew worked on the slate sections while another handled the copper work. “It was kind of a combined effort,” Hunter explains, “Naturally, we started with the slate, but there were parts of the standing seam we had to do before we could continue with the slate. I would say the slate was about 85 percent done, and then we did all the copper. We had to go back and actually put on the remaining 15 percent of the slate after the copper was done. There was a lot of coordination involved in that.”

Slate and Copper

For the slate sections, crews installed ice and water shield from PABCO along the eaves, valleys, hips and ridges, as well as Precision’s private labeled synthetic underlayment.

The slate roof combined products from of two different suppliers. North County Black Slate was blended with a Vermont Slate Unfading Green. “I think that North County Black is the nicest slate in the world,” Hunter notes. “It’s amazing stuff. We took that and blended it in with the Vermont S1 Grade Unfading Green.”

Slate can have natural color variation, and proper blending is essential. Hunter estimates that the blending process took 60 man-hours to complete. “The blending is all done on the ground,” he says, “We took one piece of slate from every single palette of the North Country Black and blended that together. We did the same with the Unfading Green. That was all blended, and then we blended the two colors together to come up with the percentages on the roof. When that slate was brought up on the roof and put on the toe boards, it was brought up there to be put on in that order.”

The slates had been hand punched at the quarry with two nail holes. Approximately 22,700 square feet of slate was installed using copper nails

Copper was the only option considered for the low-slope roof sections and details. “Copper should be used, in my professional opinion — if not lead — on every single slate roof in the country, no matter where it is,” Hunter says. “Copper is the only metal that can withstand freeze-thaw, the elements, and the heat for hundreds of years. In Texas, lead isn’t popular because, believe it or not, squirrels love lead. It’s like a snack to them.”

Flashing, gutters, downspouts and other details were fabricated from scratch. “Any slate or tile project we install, no matter what, has copper everything on it — drip edge, valley metal, step flashing, counterflashing,” Hunter says. “Every one of the pipe jacks you see on that roof was hand made from copper. All of the gable vents, dormer vents and any other vents were fabricated by us either on site or in our warehouse.”

Approximately 3,700 square feet of double-lock copper panels were fabricated on the site. “Those panels were taken up, and if any modifications needed to be made, we had our bender, our breaker and our cutter up there at the very top,” Hunter notes. “We hand crimped and hand bent every one of those panels up there on the roof. We made sure those double locks were nice and tight. It probably took about two weeks to do all of the copper.”

Hunter credits his experienced crews for their expert workmanship. “Where there would be a hip or a valley, everything was soldered,” he says, “Soldering is very time consuming. You’ve got to really know what you’re doing.”

Challenges included notorious Texas weather and steep terrain at the back of the house that made access difficult. The slate could only be delivered in the front and had to be carried to the back. “This house was hard because in the back the scaffolding went up three stories,” Hunter says. “There’s a patio area in the back that actually drops down a story.”

Crews were tied off 100 percent of the time for fall protection. “That roof is so steep that you have to be very careful and use every safety measure you can,” Hunter says. “Those standing seam roofs are 45 or 50 feet up in the air.”

The completed project shows off the craftsmanship that is the hallmark of the company, according to Hunter. “It was a very, very time-consuming job, but it was not rushed,” he says. “Our slogan at Precision is ‘#We Build Pretty Roofs.’ It’s kind of spread. People will say, ‘You’re the guys who build the pretty roofs!’ That’s been our hashtag and our motto for years. We just really take pride in our work.”

Innovative Approach Solves Re-Roofing Puzzle at Oceanside Resort

The existing metal roof on the Ritz-Carlton Coconut Grove was removed and replaced with 30,000 square feet of the Sarnafil Decor PVC roof system. Photos: Coatings Application & Waterproofing Co.

Sometimes re-roofing projects are pretty straightforward. Others can present a complex puzzle. Sometimes looking at things in a different light can lead to an unexpected solution that proves more cost-effective and less intrusive for the building and its occupants.

The Ritz-Carlton Coconut Grove in Miami, Florida, serves as an excellent example. The hotel consists of two 26-story towers, and each was topped with a standing-seam metal roof, with steep sections transitioning to sloped roof sections at their base.

When the original standing seam roof reached the end of its service life, the owners solicited bids to replace it with a new standing-seam metal roof. The installation would require large construction cranes to be mounted near the entrance of the property.

Bill Devine, area manager for Coatings Application & Waterproofing Co., was convinced a new metal roof was not the answer. He proposed installing the Sarnafil Décor PVC system as an alternative, asserting it would be more cost-effective, more durable and less invasive to the hotel owners and guests.

Devine’s intimate knowledge of the jobsite helped him craft his plan. “We had an existing relationship at the Ritz,” he explains. “We went in about nine years before that to repair the metal roof that was up there. We patched it after some storms and painted it for them. We’ve helped them out with some other stuff over the years, and the consultants came in to talk to them about taking the metal roof off and putting a new metal roof back on it. That’s when I got involved to try to convince them otherwise.”

There were several key factors influencing Devine’s recommendation, including the harsh, corrosive oceanside environment, which is tough on metal. “I convinced them to use the Sarnafil PVC Decor Rib System, which has the appearance of a standing seam metal roof,” Devine says. “The average person who looks at it doesn’t know it’s not a metal roof, but it’s all PVC. The way I designed it, there is not one piece of exposed metal that can rust anymore.”

With the PVC system, all the roofing materials could be brought up using the service elevators, eliminating the need for a crane. To top it off, it would be less expensive than a new metal roof.

“What got us the job was when I gave him my price for the Sarnafil and told him I wouldn’t have to have a 200-300 foot crane sitting in front of the Ritz Carlton for eight months,” notes Devine. “I took the entire roof off and put the whole new roof on using the service elevator.”

Challenging Installation

Coatings Application & Waterproofing (CAW) installed approximately 30,000 square feet of the PVC system. The steepness of the roof sections posed obvious challenges, and CAW developed special swing stages to remove the existing metal roofing and install the Decor system. “That’s 250 feet in the air with a 23/12 pitch,” notes Devine. “It’s almost a wall.”

Coatings Application & Waterproofing used special swing stages to remove the existing roof and install the PVC system.

A detailed safety plan was paramount. Crew members had to be tied off 100 percent of the time, and all tools were tethered. Anchor points were attached to the building’s heavy-duty steel framing at the top of the towers. “We drilled through that and put anchors through those big beams and ran our safety lines and swing stages through that,” says Devine.

The plan was to take everything up through the roof hatches, including the swing stages, which were engineered to fold up for transport. Debris was taken out the same way.

“We pulled all of the metal off a section at a time and dropped it down through the roof hatch,” explains Devine. “Each side had a roof hatch and we dropped it through there to the floor. We had guys inside who separated the trash from the metal and stacked it. We recycled all of the metal.”

Logistics at the jobsite were very tight. “The property doesn’t really have a parking lot area — it has a parking garage — so we had no place to put dumpsters. We just had a few spots down in the parking lot to stack insulation and rolls, and we took material up the freight elevator whenever we were ready for it.”

Recycled metal and debris were also taken out via the freight elevator. “We brought it down on a Friday, and we had a guy with a truck who would meet us at the loading dock. We’d load all of the trash in his truck and he’d take it to the dump,” Devine says. “There was nothing easy about it.”

Work on the project included installing new drains, tapered insulation and PVC membrane in the internal gutters.

As the metal roof was torn off in sections, roof areas were covered with 1.5-inch isocyanurate insulation with quarter-inch DensDeck bonded to it with adhesive. The pre-assembled 4-foot-by-4-foot boards caused some difficulties. “We had to make modifications to the swing stage so they could stack insulation on it,” notes Devine. “We dropped all of the trash down through the roof hatch, but when we went to pull our insulation up, it wouldn’t fit through the roof hatch. We cut a 5-foot-by-1-foot hole in the roof deck on each side of the building and had the guys hand the insulation up through the slot in the roof deck. They’d stack it on the stage, take it up and start installing it.”

The insulation panels were fastened to the 20-gauge steel decking with 3-inch #15 screws and insulation plates, and a Sarnafil vapor barrier membrane was installed. The slots cut in the deck were repaired using flat-stock steel.

The Patina Green PVC membrane was adhered using Sarnacol 2170 adhesive. Crews on the swing stages worked from top to bottom, adhering about 2 feet at a time. “When they got to the bottom, then they would go back up to the top with welders and weld the laps,” Devine explains.

Applying the Decor ribs with a hot-air welder was the last part of the process. The swing stages had to be modified for this step as well. “We had to be held off far enough that we could run our welder and still keep it in a straight line,” Devine recalls. “It was a fun one.”

Work on the project included the internal gutter systems and mechanical areas. “Each corner has an internal gutter that extends 15 feet down one side and 15 feet down the other. Those were completely shot,” says Devine. “The only thing that saved them was the concrete underneath. Everything above was shot. We had to put tapered insulation and the Sarnafil membrane in those and put new drains in.”

There was no exposed metal on the project, according to Devine. The hips and ridges were made from SarnaClad Patina Green metal, which is wrapped in PVC, and the metal framing was also wrapped with PVC membrane.

Award-Winning Work

Work on the project began in February 2019 and was completed in November 2019, ahead of schedule. The project received the Sarnafil Project of the Year award for 2019. “Winning that award is a pretty good feeling,” says Devine. “We went through a lot, and Sarnafil was there to help us out.”

Detailed planning was crucial to the project’s success. “I had the luxury of plenty of time to think about all of the different things we were going to have to do,” Devine notes. “We had to make some changes out in the field, like cutting a hole in the deck, but most of it went pretty smoothly.”

Devine credits CAW’s experienced team for the success of the project. “I had a good crew,” he says, “Our foreman, Bob Hinojosa, he’s been with me for 30 years, and he is just good.”

According to Devine, this project demonstrates CAW’s ability to execute difficult projects. “We find the best way to do it,” Devine says.

Pulling Together

As we were wrapping up this issue, the country was going through a tumultuous election in the midst of a pandemic. Our November-December issue typically focuses on government and municipal projects, and as we compiled these stories spotlighting successful public projects it was hard not to reflect on the nation’s highly polarized political environment.

According to roof consultant John A. D’Annunzio, public projects are typically a solid and dependable sector of the roofing market, and he outlines tips for successfully bidding and executing public projects in this issue.

Want to make sure you get paid at the end of the job? Working for a government entity can mean that it’s impossible to file a lien or sue in civil court, so check out the article by David Keel and Richard Anderson of Cotney Construction Law, who detail ways contractors can protect themselves and make sure they are compensated when the work is done.

This issue profiles government and municipal projects of many different types, including low-slope and steep-slope work, both retrofit and new construction. Several of them involved complex roof replacements in facilities that were open throughout the duration of the project. In Baton Rouge, Louisiana, the roof on the 300,000-square-foot United States Post Office General Mail Facility was replaced with a modified bitumen system while mail processing at the facility continued 24-7. In Owatonna, Minnesota, restoring the city’s historic administration building included installing 29,000 square feet of synthetic slate — and a detailed safety plan to protect workers and members of the public.

In Sevierville, Tennessee, a community center’s roof was replaced with metal-over-metal retrofit, which cut costs and minimized safety concerns. During a new construction project nearby, a butterfly standing seam metal roof and metal wall panels were installed on Sevier County Utility District’s new multipurpose facility.

D’Annunzio, who has been a roof consultant for more than 30 years, begins every pre-construction meeting by saying, “Nobody wins unless everybody wins.” His point is that the fate of the general contractor, roofing contractor, architect, engineer and consultant are all intertwined. All of them will benefit if they work together and the project is successful. They will all suffer if the project fails and ends up in litigation.

“Nobody wins unless everybody wins.” Not a bad motto for running a roofing project. Not a bad motto for running a government, either.

Butterfly Roof and Metal Wall Panels Highlight New Multipurpose Facility

The centerpiece of Sevier County Utility District’s new multipurpose facility in in Sevierville, Tennessee is a large event space that can be used by the district or rented to the public. The building also houses large conference rooms, a training room, a fitness area, administrative offices and a catering kitchen.

The design features large clerestory windows that flood the interior with natural light and a front canopy supported by steel columns. The facility’s exterior is dominated by its striking, V-shaped standing seam metal roof and metal wall panels, which are accented by brick and fiber cement siding.

“The roof was a major design element on this project from the beginning,” says A.J. Heidel, project manager for BarberMcMurry Architects in Knoxville, Tennessee. “We used the blue butterfly roof to accent the main assembly space and we used the lower roof as a wrapping element for the support spaces.”

To execute the design, it took a talented group of construction professionals including two Knoxville-based companies: Denark Construction, the general contractor on the project, and Baird and Wilson Sheetmetal Inc., the roof and wall system installer.

BarberMcMurry, Denark Construction, and Baird and Wilson had teamed up on other projects for the Sevier County Utility District (SCUD) in the past, so they were a perfect fit for this new construction project. The roof system chosen for the building is comprised of Petersen’s PAC-CLAD Tite-Loc panels in Berkshire Blue.

“We chose a standing seam metal roof because its material properties allow for a range of colors and ribbing patterns, and because of its ability to act as a wall cladding as well as roof,” notes Heidel. “We were able to give different characteristics to separate volumes by changing from blue smooth flat lock panels to Musket Gray ribbed panels while maintaining a similar method of installation.”

The design team originally explored using insulated metal panels for the roof and walls. “We were asked by Denark Construction to price this project,” says Jim Galbraith, vice president of Baird and Wilson. “I priced the insulated roof and wall panels and Denark came back asking if there were potential savings through value engineering. We submitted pricing for single-skin roof and wall panels and it was accepted.”

To make sure everyone was on the same page, pre-construction meetings involving the architect, general contractor and roof system installer included a mock-up of the panel system. “We had a mock wall with all of the roofing and wall conditions, and we met with them on site to go over all of the details,” explains Heidel.

The Installation

Baird and Wilson installed approximately 13,500 square feet of Tite-Loc roof panels on the roof, as well as 3,500 square feet of 16-inch Snap-Clad standing seam wall panels. “We also fabricated and installed gutter, downspouts, horizontal flush wall panels, low and high soffit, and fascia,” notes Galbraith.

After the metal deck topped with a nail base, insulation, and ice and water shield, the roof panels were installed and mechanically seamed. “The slope was less than 3:12, so the Tite-Loc panel was a perfect fit,” Galbraith says.

Work began on the butterfly roof. The valley features an internal gutter, which drains through downspouts that penetrate through the soffit and go down the front of the building, where they drain through underground pipes. “At the entrance we installed some horizontal blue flush panels that matched the roof,” notes Galbraith. “We also installed the fascia and soffit in Berkshire Blue, which matched the roofs on other buildings on the campus, which were also that color.”

The roof-to-wall transition was designed to make it appear the roof was wrapping around the building. “The roof panels were 16 inches on center, and the wall panels were 16 inches on center,” Galbraith explains. “The seams on the wall panels and the roof panels had to line up perfectly all the way down, so that was a bit tricky. You had to pay attention and do the math as you were going down to make it all work.”

Challenging Site

The limited area surrounding the building proved to be a major challenge on the project. “The building itself takes up much of the buildable area, leaving little room for things like parking and site drainage,” says Heidel. “We were able to avoid a water detention pond by using rain gardens on the site.”

The rain gardens are located against the main road, with parking spaces designed to shed water to that area, which includes native plants that thrive in a wet habitat. The pipes from the building’s downspouts flow there as well.

Tennessee’s spring weather was also a concern. “Construction took place in early spring, and the wind was whipping,” says Galbraith. “It was also rainy, and there was a corner where water would sit, so we had to be careful moving our lifts so they didn’t get stuck in the mud. The most difficult problem was manhandling the long roof panels. Many were more than 50 feet long.”

Despite the challenges, the project went smoothly. “BarberMcMurry prioritizes long-term client relationships, and this project is a great example of that,” Heidel says. “We have a history of successful projects with SCUD, and we continued that pattern through this project, which was delivered on time and on budget.”

“We work with our clients on designs that fit their brand, reflect their use, and are fully functional as well as beautiful,” Heidel continues. “That outlook is reflected in this project, too, through the overall design of the spaces and our creative use of materials. Finally, BMA is committed to sustainability and stewardship through design. In this project with SCUD, you can see sustainable design elements in the rain gardens, which filter and control the release of storm water as it leaves the site, and in the building’s clerestory windows and shaded curtain wall, which take advantage of daylighting.”

The project also showcases the quality workmanship of Baird and Wilson. Galbraith cited a quote from Charles R. Swindoll that serves as a company motto: “The difference between something good and something great is attention to detail.”

New Synthetic Slate Roof Tops Historic Owatonna City Hall

The city offices in Owatonna, Minnesota, are housed in a historic building that underwent a complete roof replacement as part of an ambitious restoration plan. Photo: Lakeshore Drone Services

The massive brick complex in Owatonna, Minnesota, that currently serves as its city hall has an interesting past. According to Aaron Fitzloff, facility manager for the City of Owatonna, the structure was originally built in 1886 as the Minnesota Public School for Dependent and Neglected Children. The facility closed in 1945 and later became the Owatonna State School. “The state closed it in 1970, and the city of Owatonna took it over in 1974,” notes Fitzloff. “In 1975, the building was listed on the National Register of Historic Places.”

The complex now houses administrative offices for the city and the Minnesota State Public School Orphanage Museum. Asphalt shingles had been installed on the roof at some point in the 1990s, but leaks developed over the years, and the city budgeted for a complete roof replacement as part of an ambitious restoration plan. “The intent was to get the building back to its original state,” says Fitzloff.

Specifying a New Roof

The city consulted with Adsit Architecture and Planning, a full service architectural and interior design firm located in Minneapolis. When the firm completed a condition assessment for another historic building in Owatonna— the Firemen’s Hall —that project led to a request from Fitzloff to look at the city’s administration building.

Crews from Schwickert’s Tecta America installed more than 29,000 square feet of DaVinci synthetic slate. Photo: Lakeshore Drone Services

“Aaron realized that all of the roof systems were in need of replacement at this point,” says Gunstad. “He wanted to make sure, first and foremost, that we mitigated any moisture problems that were occurring up in the attic space. The project was about insulation as well as roofing.”

Finding the right roof system was crucial. Evidence suggested that the original roof was comprised of slate, but that couldn’t be confirmed due to a fire that had destroyed the main building in 1904. “Even before we did our research, we knew from our first look at the building that an asphalt roof on a building of this mass and scale did not look right,” Gunstad says.

Adsit Architecture specified a synthetic slate roof system manufactured by DaVinci Roofscapes. “Right off the bat we felt that given the scale of the building that slate would have been prohibitively expensive for them, and they agreed,” Gunstad recalls. “We knew with the cost, ease of installation, the warranty, the weight — all of that — the synthetic slate would be a really good fit, and DaVinci had an enormous amount of color choices for the blends we needed.”

DaVinci’s Color Visualizer Tool was used to help determine the colors. A European blend of gray shades and purple was installed. As the project got under way, the hunch that the original roof was slate was confirmed. “When we got into reconstruction and were up digging around in the attic, we did find some old slate pieces,” Gunstad recalls. “Oddly enough, they were a perfect match for the colors we had chosen.”

Installing the Roof Systems

The installer on the project was Schwickert’s Tecta America, headquartered in Mankato, Minnesota. “We ended up being the only bidder on it, which of course you don’t know at the time,” notes Scott Haefner, Schwickert’s steep slope project manager.

The scope of work on the project included 60-mil Carlisle EPDM, new gutters and custom-fabricated metal trim. Photo: DaVinci Roofscapes

According to Haefner, the difficulty of the project is what made it appealing for the company, which thrives on projects others turn away from. “Those are the ones we look for — the ones that have some complexity to it,” says Haefner. “That’s where we can shine. We have our own metal shop, we can do all our own metal fabrication, and we can do the types of things that can really set us apart. It gives us an advantage because we don’t have to farm some of that work out, and we have complete control over the whole process.”

The scope of work included installing more than 29,000 square feet of the DaVinci synthetic slate. The roof also included low-slope areas, and for these a 60-mil EPDM from Carlisle was installed. Sheet metal work included new gutters and custom-fabricated metal trim.

The safety plan was crucial, as the building would be open during the construction process. “You start with the safety plan,” says Haefner. “With staff and members of the public walking in and out, it is critically important in your pre-construction meetings to address those issues with overhead protection in certain areas, and blocking off certain areas when you’re working above them for the day.”

The safety plan incorporated scaffolding and personal fall arrest systems, as well as overhead protection for pedestrians. Photo: Schwickert’s Tecta America

Coordination with the city staff was critical. “Aaron Fitzloff helped us tremendously in that area,” says Haefner. “We had a standing meeting every Tuesday morning at 9, and that was always a big part of the conversation — safety and the sequence of what we were going to do that day. Aaron and I would also see each other every day also, typically. He was a great attribute to the whole project, for sure.”

Safety equipment included scaffolding and PFAS. “The vast majority of the building was scaffolded,” Haener says. “Fall arrest was anchored to the roof in areas we didn’t have scaffolding, and even where we did, the roof pitch was steep enough that everyone was always tied off with anchors and fall arrest systems.”

Work began in the late fall and progressed in sections. “That’s part of the beauty and charm of the building — its different additions and roof sections,” notes Haefner. “That also allowed us to focus on one area at a time. That’s typically what you do — you start and do a section that’s kind of an easy one to just get your feet underneath you and get a feel for how it’s going to go. There were some big, long planes of roof that we were able to get a start on and get a feel for the whole sequence.”

Schwickert’s steep-slope division handled the composite slate roof installation, while its flat roof division tackled the EPDM roofs.

Tying in flat and steep-slope roof systems was critical. Steep slope-crews completed most of their work first, using a Grace Ice & Water Shield product that is compatible with EPDM. “Let’s say you know the EPDM is going to go let’s say two feet up the slope of the roof, from flat to transition up the steep slope,” Haefner explains. “We’d leave off the bottom two or four courses of shingles, and leave the ice and water shield exposed, but not adhered.”

Photo: DaVinci Roofscapes

Low-slope crew members would just flip up the ice and water shield and install the EPDM. Steep-slope crews would then install the metal flashing, adhere the ice and water shield, and add the final courses of shingles.

A snow retention system from Rocky Mountain Snow Guards was installed in several sections of the roof.

Re-roofing the large turret was made easier by DaVinci’s turret package, which supplies pre-cut tiles. “You give them some basic information, including the circumference and the pitch,” Haefner says.

It worked well on the project, with one minor hitch that was quickly remedied. “This one was a little different because it has a sort of witch’s hat appearance to it, where the pitch changes at the bottom,” Haefner says. “It’s not a typical cone shape. When I sent in the request for the package, I didn’t take that into account, and we needed to order some more shingles to finish the turret.”

The large finial on the turret was taken down, painted and replaced.

A heat mesh system was installed in certain areas that had been subject to ice dams in the past. The Warmquest Zmesh system consists of woven copper mesh, which was installed below the tile, sandwiched between layers of ice and water shield. “That was a tricky part of the installation,” says Haefner. “We had to run big transformers, electrical panels, and run conduit to these areas from the old attic.”

The Minnesota weather brought things to a halt in the mid-winter, and work concluded this spring.

Mission Accomplished

Haefner points to this project as proof of his company’s ability to complete projects with multiple scopes of work. “With steep slope, flat roof, sheet metal work, new gutters, insulation, and the electrical portion involved with installing the heat mesh system — it shows perfectly how we can install multiple complex systems that have to go together in a certain way,” he says. “That type of complexity is where we shine.”

The city and its residents have been pleased with the result, according to Fitzloff. “Feedback has been nothing but positive,” he says. “We cleaned all of the limestone around the whole building as well, and it looks fabulous.”

Gunstad notes that the project fulfilled its design goals: making the building sound and restoring it to its former glory. “Performance and maintenance of the project were our primary concerns, but design-wise, looking at this building, which is rather grand, we knew it lacked something — and that something was a substantial roof,” says Gunstad. “We wanted to give that visual prominence back to that building, which is a hallmark of the city.”

A Green Future

The cover story of this issue is titled “Roofing for the Green Future.” The article documents the design and construction of The Kendeda Building for Innovative Sustainable Design on the campus of Georgia Tech. The design team decided to meet the rigorous performance requirements of the Living Building Challenge — the world’s most ambitious green building program.

A TPO roof system with optimal polyiso insulation, energy-efficient mechanical systems, and a rooftop solar array are designed to help the 46,800-square-foot Kendeda Building produce more energy than it uses. The roof is also designed to capture rainwater for collection into an underground cistern. It is also home to a 1,000-square-foot accessible roof deck and a 4,300-square-foot rooftop garden, complete with a honeybee apiary.

The Kendeda Building is an amazing example of sustainability, resilience, and energy efficiency in action, but the headline “Roofing for the Green Future” would have worked on every project profiled in this issue. The designers, installers, and manufacturers of the roof systems detailed here all focused on bringing energy efficiency, durability, and resilience to life.

Examples include the metal and modified systems installed on the new Latrobe Elementary School; the synthetic slate, built-up, and green roof systems on the University of Minnesota’s renovated Pioneer Hall; the new EPDM system installed on the 66,300-square-foot hyperbolic paraboloid roof of the athletic complex at Clarkson University; and the energy-efficient wall systems on the new gymnasium at Pacific Christian.

On a massive Texas project, 195,000 square feet of a high school’s campus was re-roofed with a highly reflective modified system to alleviate concerns about the urban heat island effect. At an elementary school re-roofing project in Michigan, an energy-efficient PVC roof system was installed and 8,700 pounds of the old PVC membrane was recycled, keeping it out of the landfill and resulting in a lower cost for the school district.

It’s rewarding to cover projects that embody a true win-win-win scenario. Installing a truly resilient roof system can provide optimal protection for building occupants, ease the burden on the environment, and offer a lower life-cycle cost to the owner. You don’t hit that trifecta in business very often.

In a year in which “back to school” has a radically new meaning for many, it’s uplifting to see these educational facilities being constructed for the long haul. For many, the first day of school this year found students at home, in front of their computers. Let’s hope everyone will soon be exploring a brighter future together, in buildings designed to bring out the best in us.
