After a Hailstorm, Nineteen Office Buildings Are Restored During the Winter

Featuring 22 office buildings, fitness, conference and training centers, plus a hotel, the Denver West Office Park is an impressive complex. So, when it came time to re-roof 19 of the buildings with composite roofing tiles, it took two talented roofing crews to handle the project.

“Our crew re-roofed 14 of the buildings at Denver West,” says John Werpy, estimator/project manager for Arapahoe Roofing. “We had 85 installers on the project for four months straight. Access to the buildings, which are four stories tall, was a challenge. And, we could only load product on the weekends to minimize disturbing the tenants.”

The true challenges for Denver West began on May 8, 2017. That’s when a massive hailstorm caused extensive damage to the existing real cedar roofs on all of the structures. The National Weather Service reported hail that day ranging in sizes from golf balls to large eggs. One of the largest pieces of hail was recorded at 2.75 inches in diameter.

With the idea that the complex needed more durable roofing in case of future hail storms, the search was on. The result was the selection of resilient composite shake tiles from DaVinci Roofscapes. The Bellaforté Shake tiles chosen for the complex are Class 4 impact resistant and Class A fire rated. The tiles are also designed to resist high winds (up to 110 mph), curling, cracking, insects and algae.

Once the roofing system was selected, the clock was ticking. The property owners started the project in October 2017 and set a deadline of April 2018 for completion of the roofing. Arapahoe Roofing and Gen 3 Roofing were brought in to tackle the massive composite roofing project, which continued right through the bitterly cold winter months in Denver.

Winter Installation

“We immediately started removing the damaged cedar shake roofing, but then discovered asbestos felt problems in some buildings,” says Cameron Hummel, CEO of Gen 3 Roofing. “After dealing with those issues, we went on full-push to meet the deadline.”

“For our company, this project was very personal,” Hummel continues. “We’re a third-generation family of roofers and our family has been roofing the Denver West office complex since the 1970s, when they were first built. Just as our name implies, we’ve roofed these same buildings for three generations … in the 1980s, 1990s, early 2000s, and now again in 2017/2018. We’re proud that we accomplished our portion of the re-roofing project during the winter months ahead of schedule and without any injuries or safety violations.”

Winter weather was top-of-mind for the installers of the project. The first freeze in the Denver area arrived on October 10, making for a cold installation. Fortunately, DaVinci products are made of an engineered resin system designed so that tiles remain flexible for installation in colder weather. DaVinci composite tiles can be installed in temperatures as cold as 20 degrees.

“Our guys had many cold days of installation with this roofing project,” says Hummel. “However, we were able to keep on schedule because of the DaVinci products.”

When complete, the Denver West project had used 560,000 square feet of DaVinci composite shake tiles, 390,000 of them installed by Arapahoe Roofing.

“This was an ‘all hands on deck’ type of project,” says Werpy. “Re-roofing 14 structures in just a few months is intense. Our teams also re-lined the existing internal gutters and installed thousands of Rocky Mountain Snow Guards around the structures to help protect snow from avalanching down on cars and people below the roofline during winter months.”

Located the heart of Halifax’s Spring Garden Road district, City Centre Atlantic features a mix of urban retail, office and residential space totaling 31,600 square feet. The site has 194 underground parking spaces servicing the office and retail components of the property.

Multiple challenges came with the City Centre Atlantic project for installing roofing contractor IC Roofing and Sheet Metal of Bedford, Nova Scotia. I.C. Roofing and Sheet Metal Limited is a Maritime-based company servicing Nova Scotia, Prince Edward Island, New Brunswick, Newfoundland, and Southwestern Ontario. The site offered limited street access and rooftop storage space was limited, necessitating extra movement of materials up on the roof.

The building owner was looking for a durable system with a proven track record, so a heat-welded modified bitumen system manufactured by IKO was selected. After the concrete deck on the 2,936-square-foot City Centre Atlantic roof was covered with Modiflex MP-95-FS vapor barrier, IKOTherm and IKOTherm Tapered insulation were installed using Millennium adhesive. After the cover board was installed. I.C. Roofing crews then heat welded the Torchflex TP-180-FF base sheet and light gray Torchflex TP-250 cap sheet. They also fabricated and installed the edge metal on the project.

Everything on the job went smoothly, according to Mike Croft, Atlantic Regional Manager, I.C. Roofing. The key to success on projects like this? “It’s experience,” Croft says. “I.C. Roofing ensures a quality installation through project management and employing journeyman roofers that are great tradesmen. The guys we have undertake these jobs are great journeyman roofers who do two things: they understand the tasks they are doing, and they take a lot of pride in what they are doing. You can have journeyman roofers that can install most things, but it takes a special journeyman roofer to make it look worthy. That’s stuff you can’t teach. A guy has to have that. Our guys take personal pride in their work.”

Metal Tiles Help Modernize Texas Bank’s Building and Brand

The design for the bank’s exterior incorporates metal tiles from Petersen to clad the building’s two entrances. A standing seam metal roof wraps around the building, intersecting with the metal tile. Photo: Tom Coplen, buenavistaphotography.com

When Southside Bank in Texas began a campaign to modernize its brand, management understood that the buildings it occupies play a significant role in branding. The existing flagship branch in Tyler, Texas, was re-imagined and renovated inside and out to reflect the contemporary way the bank now interacts with its customers.

Architect Chad Humphries AIA, RID, project architect and partner, Fitzpatrick Architects in Tyler, Texas, extracted the vision for the renovation from the Southside team and created the bank’s signature design element using metal tiles from Petersen to clad the building’s two entrances. A standing seam metal roof wrapped around the building, and intersected with the metal tile at the entrances.

Humphries specified 10,000 square feet of Petersen’s Snap-Clad roof panels in 22-gauge steel finished in PAC-CLAD Slate Gray color. Also specified was 2,000 square feet of Petersen’s Precision Series TS Tile in .023 aluminum finished in anodized dark bronze. Additionally, 500 square feet of Petersen’s composite rain screen in Classic Bronze finish was installed.

“The tiles were the main design element we wanted on the entryways, to function as both wall and roof material, to blur the line between roof and wall,” Humphries says. “Metal tiles have been around in Europe for centuries, and we employed the PAC-CLAD Precision Series TS Tile as a modern option. Metal has a timelessness that is appealing, and in this project it achieved the aesthetic vision and performance needs we established.”

The tile concept on the entryways was such a success on this project that it will be duplicated on many other Southside Bank buildings. Humphries likes the metal tile’s low profile and the way it also adds texture to the wall. “I especially like the way the light interacts on the tile’s surface, which allows for a wall that changes its appearance as the sun progresses across the sky throughout the day,” he says.

When selecting products for any project, Humphries values how long a product has been on the market. “Even though the Precision Series TS Tile hasn’t been around a long time, it was Petersen’s version of a product with proven history and that was good enough for us,” he notes.

Design Challenges

Where the tile on the entryways met the standing seam roof, a junction not often encountered was created. The tile-to-panel junction was easy to deal with because ultimately it was a simple metal-to-metal joint, according to Humphries. “Additionally, the tile allowed for a 45-degree turn without requiring edge band,” he says.

A metal roof was chosen because of metal’s longevity, and the need to blend in to the building’s design, notes Humphries, who typically specifies some kind of metal element on every project. Design challenges included peeling back and sorting through the multiple phases of additions and renovations inside and outside of the building, ultimately to be truer to the original design of the building. “For example, in the 1970s they added a concrete superstructure. But in the 90s, rather than removing it, they built a giant green mansard roof over it. Over time the building’s design became a mixture of ideas with no clear vision in mind. Our job was to simplify and unify everything,” he explains.

This project was the first one for installing contractor Curtis-McKinley Roofing and Sheet Metal in Longview, Texas, on which metal tile was involved, says Anthony McKinley, vice president, estimator and project manager. “The tiles tied into a valley with the existing roof, so we made sure they were cut properly and flanged,” he says. “Installation of the tile and standing seam roof was straightforward for our experienced crew. It was a slower process working with the tiles because we wanted to make sure the lines were straight, level and square. The details were custom so we took a little longer to make sure we measured correctly and got it looking right.”

All metal work on the building was performed by McKinley’s team. “This job was large in scope mainly because of the removal and replacement of the mansard roofing,” McKinley says. “After taking off the roof panels, we removed fake dormers to create a straight, plain look. We tore everything down to the wood deck. Ultimately, we were at least six months on the jobsite. Most of our time was spent removing the existing metal, which required a man lift, which is a slow process.”

“We felt it was important to make sure the owner and architect liked what we were doing by not making design decisions on our own,” McKinley says. “Some jobs you know what to do, but on this one we wanted to make sure the architect liked it. We figured out details to make it work for integrity and water intrusion, but also to give the architect the look he wanted. We figured out the details on our own because those typically aren’t specified.” Edge metal was fabricated by McKinley’s crew. “We love working with PAC-CLAD,” McKinley says. “They have superior products, and the technical help Petersen provides is very valuable.”

New Fluid-Applied Membrane Is Designed to Be Tough, Virtually Odorless, Easy to Apply

Garland’s first ever fluid-applied seamless membrane, LiquiTec, forms a virtually impenetrable surface over aged modified bitumen, metal and single-ply roof systems, adding years of waterproofing protection. LiquiTec is an aliphatic polyurea coating system with a tightly bonded molecular structure that provides strength and durability similar to truck bed liners. LiquiTec is built to protect roof surfaces from damage caused by hail, foot traffic, wind scour and other impact.

According to the manufacturer, LiquiTec fully and partially reinforced systems exhibit extremely high tensile strength and remain flexible at temperatures down to -60°F (-51°C), which helps keep the coating from cracking or becoming brittle to ensure a complete watertight seal and long-term waterproofing protection. In addition to its strength, LiquiTec contains zero VOCs and is extremely low odor to allow roof work to be completed with minimal or no disruption at sensitive locations like schools, hospitals and other structures where people are present. 

This two-component product also undergoes a chemical cure process, rather than a moisture cure, so it cures quickly and with less disruption from weather, allowing for faster installation and waterproofing protection. 

“LiquiTec is the answer to so many of our customers’ waterproofing needs. Its unique formulation, strength and flexibility provides the right amount of toughness combined with superior waterproofing protection,” said Ed Buczek, Garland’s senior product manager of roof coatings. “And to top it off, the fact that it is extremely low odor, highly flexible, resistant to fungi and chemically cured allows it to be installed nearly anywhere and perform in the most extreme environments.”

Firestone Building Products Aids Official Carbon Partnership Between Dow and the IOC

Marking the first carbon mitigation project in North America under the Official Carbon Partnership between Dow and the International Olympic Committee (IOC), Dow announced its collaboration with Firestone Building Products, a subsidiary of Bridgestone and a manufacturer of commercial building performance solutions. The collaboration is supporting the creation of an energy modeling tool to accurately describe reductions in cost, energy and greenhouse gas (GHG) emissions of commercial structures that use innovative polyurethane roofing insulation from Firestone Building Products. This insulation, developed by Firestone and enabled by Dow’s polyurethane raw materials, addresses low-temperature thermal drift without compromising the other performance metrics. 

“With cities growing at a rapid pace, it is paramount that we as an industry evaluate and implement innovative new materials to accelerate the adoption of solutions that mitigate greenhouse gas emissions in the infrastructure market segment,” said Dr. Nicoletta Piccolrovazzi, circular economy market director for Dow and global technology & sustainability director for Dow Olympic & Sports Solutions. “Firestone Building Products shares our vision, and enabled by the Dow-IOC Official Carbon Partnership, we’ve embarked on a mission that will empower architects, contractors and building owners to better identify energy saving solutions and improve decision-making, doing their part to create a low-carbon legacy.”

The new energy modeling tool – to be available on Firestone’s website in 2020 – is being developed by Oak Ridge National Laboratory (ORNL) with funding support from Dow. With this new tool, commercial architects, property owners, roofing consultants and construction companies can scenario-test the potential long-term reductions in whole-building energy use and the associated GHG emissions resulting from installation of the ISOGARD newly-formulated Firestone polyurethane foam roofing insulation. Use-phase building energy consumption is compared within the modeling tool to alternative roofing technologies, allowing for informed selection of material and amount of insulation. This ability to compare performance will be particularly valuable for cold climate zones of the United States and Canada, where temperatures drop below 40 degrees Fahrenheit and older polyurethane foam formulations experience a drop in their insulation performance. 

“Partnering with Dow and working with ORNL to create a modeling tool will help to validate, quantify and reinforce Firestone’s commitment to sustainable building solutions,” said Taylor Cole, president, Firestone Building Products. “Sharing the tool on our website for everyone to use is just another way we’re working with industry partners to not only provide attainable solutions for our customers, but to also work together to do our part in reducing carbon emissions.” 

The new whole-building energy modeling tool will be used to further promote and advance the adoption of Firestone’s ISOGARD roofing insulation, enabled by Dow polyurethane raw materials. ISOGARD foam is formulated to retain more of its R-value (insulating value) at temperatures below 40 degrees Fahrenheit compared to existing polyurethane foams. This formulation is designed to create tighter building envelopes and improve building energy efficiency, without changing the installation qualities—such as thickness, compressive strength, weight, and dimensional stability—of the roofing boards. The formulation is estimated to increase the R-value of the roofing material from 5.5 to 6.3 per inch when tested at 40 degrees Fahrenheit and lower. For commercial construction trade professionals, this translates to improved energy savings and can contribute to obtaining Leadership in Energy and Environmental Design (LEED) certification.

This agreement is the second of several anticipated joint efforts that will result from the Collaborative Blueprint for unlocking carbon reductions announced last year by Dow. The first agreement was signed in April with PETRONAS Chemicals Glycols. The Blueprint underpins the Dow-IOC Official Carbon Partnership, initiated in 2017 to balance the operational carbon footprint of the IOC, and encourages organizations outside the Olympic movement to adopt programs for reducing carbon emissions while catalyzing change across value chains.

Award-Winning Re-Roofing Project Showcases Quality Workmanship

Photo: Duro-Last

Replacing the roof on an occupied building with multiple tenants means not only meeting the needs of the building owner but several other businesses as well. When the roof is high above a busy metro area, the job can be even more demanding, but when the failing roof on a CBRE Group high-rise in Cambridge, Massachusetts, needed to be replaced, Commonwealth Building Systems was up to the challenge.

Located near the Longfellow bridge across the Charles River from downtown Boston, the building houses a variety of business and retail tenants. RMX Northeast Inc., the consultant on the project, specified the use of a PVC roofing system from Duro-Last to replace the existing stone-ballasted system and invited local contractors to bid on the project. Commonwealth Building Systems of Rockland, Massachusetts was awarded the job.

Photo: Duro-Last

Commonwealth is a commercial roofing and sheet metal contractor that focuses on the Boston and Cambridge area. Daniel Hulverson, principal at Commonwealth Building Systems, knew the logistics on the project would be a challenge. Due to construction taking place on the Longfellow Bridge at the time of the project, traffic in the area was diverted around the building, and use of a crane was limited to Saturdays. The Commonwealth team commissioned the use of a 300-ton crane on two consecutive weekends to remove the stone ballast, pavers, and existing EPDM membrane from the 180-foot-tall, multi-level roof.

“The ballast removal was probably the hardest part of the project,” Hulverson recalls. “We couldn’t do any work doing the week because of the tenants for one, because of the noise, and the Longfellow Bridge was under construction at the time. It was actually closed, so traffic was pretty much a nightmare.”

R.K. Hydrovac was called in to remove the stone ballast. The crane was used to hoist the vacuum hoses to the roof. “It was quite an undertaking on their end,” Hulverson says. “We got the stone ballast off and got all of the stock up there on two consecutive weekends. Actually, after the first weekend we were able to get started roofing. We stockpiled all of the trash and got most of the trash off on the second weekend. We had a couple more crane days to get trash out at the end, so we had maybe four of five crane setups in all.”

A Custom Solution

The new roofing system was designed to stand up to the area’s high winds. Leaving the existing insulation in place, the Commonwealth crew covered each roof area with 2 additional inches of Duro-Guard ISO II insulation, which was mechanically attached. The upper roof was above a steel deck, and the lower roof covered a concrete deck, so different fasters were used, but the fastening patterns were identical.

After the existing ballasted EPDM system was removed, crews installed a thermoplastic roof system manufactured by Duro-Last. Photo: Duro-Last

After the insulation was in place, the Duro-Last PVC membrane was attached using the Duro-Bond induction welding system. The membrane is delivered custom fabricated to fit the site. “Duro-Last comes out and pre-measures the job with our assistance, and then the sheets are made,” Hulverson says. “They give you a map and tell you where the sheets go. They measure around all of the penetrations, and everything is pre-cut. It’s pretty cool how it comes out. The rolls are listed A, B, C, D, and so on, and you just kick out the rolls and weld them in place. The sheets are pre-welded at any laps, so it reduces the amount of welding you are doing on the job and saves time.”

The Duro-Bond system uses specially coated plates that are screwed down to the deck before the membrane is put in place. The membrane is adhered to the plates using an induction welder.

Work began on the upper level and moved down to the lower level. “We went from side to side, working our way toward where the crane setup was going to be,” Hulverson explains

The upper roof was constructed over a mechanical room, so crews could work any time without fear of disrupting the tenants. Work hours were restricted on the lower level because it covered occupied business space. “We had to switch to very early hours in the morning because of the noise,” Hulverson notes. “We were starting at three in the morning so we didn’t disrupt the tenants.”

Commonwealth’s dedication to quality workmanship on the project earned the company Duro-Last’s Edge-to-Edge & Deck-to-Sky Award. Photo: Duro-Last

Staging areas were moved as the project progressed to limit the possibility of damage to the completed sections of the roof. On the last day, the roof membrane was protected by tarps and plywood as the final loads of debris were removed.

The safety concerns were straightforward. “There was a parapet wall that was above 42 inches high around the whole perimeter of the building, so safety-wise, this job was fairly easy for us,” Hulverson says.

Custom-fabricated curbs and stacks were utilized to help reduce rooftop labor. “All of Duro-Last’s curbs and pipe seals come pre-made, and they are all listed on that diagram,” Hulverson says. “You just unfold them and weld them. The corners are already pre-done. It’s a very nice system.”

Commonwealth’s sheet metal division installed all of the edge metal, which was custom fabricated by EXCEPTIONAL Metals. “Again, Duro-Last measures everything along with our superintendent, and it’s all sent out prefabrication,” Hulverson says. “The pre-assembled wall cap was installed on top of the walls.”

During the last phase of the project, Walkway pads were welded down in high-traffic areas.

Luckily, weather wasn’t a key factor. “There were some challenging windy days, as there always are in Boston, but nothing I can really remember that slowed us down to the point we couldn’t work,” says Hulverson. “The weekend crane setups and the size of the crane were unusual, but other than that it was a pretty smooth job. And the views are beautiful — you’re looking across the Charles River into Boston, so it was pretty nice.”

Commonwealth’s dedication attention to detail on this project earned the company Duro-Last’s 2018 Edge-to-Edge & Deck-to-Sky Award, which was presented in 2019. “Duro-Last was impressed by the neatness of the job, especially the wall flashing,” Hulverson says. “They were impressed with our workmanship. If there were any challenges or changes, we just met them head on and moved forward, like we typically do. The customer is always first.”

Hulverson believes the key to ensuring quality workmanship is dedicated employees, from top to bottom. “Our foremen are well trained, as are our superintendents, and I actually look over the jobs in the field as one of four owners,” he says. “We make sure the quality and craftsmanship are done the right way.”

Novagard Sends Building Materials to Tornado-Ravaged Dayton Community

Novagard Solutions Inc., a Cleveland-based manufacturer of highly-engineered foams, sealants, coatings, lubricants, and thermal management products for the construction, electronics, transportation/automotive, manufacturing, medical and military markets, donated 38 skids of the company’s NovaFlexand NovaBond silicone and hybrid construction sealants (caulk) and weather-stripping to tornado-ravaged Dayton, Ohio. In May, the Dayton area was devasted with over 15 tornados damaging homes and businesses with rain and high winds. The materials donated directly to Habitat for Humanity of Greater Dayton will be used to install windows, doors, siding, shutters, and roofs. Two trucks, donated by MDL Logistics, transported the materials, which were worth more than $200,000. With over 30,000 tubes of caulk, thousands of homes will be able to be repaired and made livable before winter sets in on the damaged community.

“We have many employees from the Dayton area, and we felt this was a great opportunity to step in and address a critical need,” said Sarah Nash, CEO of Novagard. “Novagard is in a position to help with the recovery and repair of scores of homes. We also appreciate the partnership with Habitat for Humanity which is coordinating the use of our products directly with contractors.”
