Wildwood School

Since its founding in 1976, Wilson Pacific Roofing has garnered a well-deserved reputation as one of Southern California’s top commercial roofing companies.

Wilson Pacific Roofing logo“Over the last 44 years, we have roofed and re-roofed the same buildings for our clients since we opened,” says owner Rick Wilson. “They are not only happy with our quality re-roof work, but our clients are also very pleased with our guaranteed roof maintenance and repairs.”

When Wilson Pacific was called on to perform a re-roof project at Wildwood Middle and Upper School in Los Angeles, California, they knew Polyglass was the project’s brand of choice. To ensure the highest level of quality and to meet the project’s specific needs, they tapped their Polyglass technical advisor, Rick Mapes, to formulate a roof system specially designed for the school.

Project Needs and Challenges

Wildwood High School occupies a single large building consisting of a twin-barrel roof structure with a flat blind valley separating the barrels. The previous Glascap roof was showing signs of wear but was still in fair condition. The original plan had been to repair and re-coat the existing roof, but the team soon determined that the planned installation of 21 new skylights and six HVAC systems would make that strategy impractical. In addition, the roof needed to be able to stand up to a considerable amount of wear-and-tear. “We [were] aware that foot traffic was going to be a frequent occurrence,” says Wilson. “We needed a tough and durable roof system to meet this challenge.”

Mapes and the Wilson Pacific Roofing team determined that the best solution would be to recover over the existing roof structure using Polyglass products. “The structure can easily support the additional weight,” says Wilson, “and at the same time, we could save the existing roof insulation.”

The team began by leveling the roof deck, filling in the insulation gaps left by the skylights and HVAC installations using new 4″ polyiso insulation and 1/2″ Densdeck.

After priming the surface with Polyglass PG-100 Fast-Drying Asphalt Primer, they applied the 2-layer Polyfresko G Roof System, which consists of a Polyflex APP modified bitumen membrane welded directly to the roof, followed by the application of the Polyfresko G Modified Cool Cap Sheet.

The team specifically chose the Polyfresko G system due to its patented CURE Technology. This innovative thin film technology offers enhanced performance benefits that include UV stabilization, granule adhesion, high reflectivity, scuff resistance, and stain resistance — all of which make the roof system particularly robust and durable for many years to come.

Fiat Chrysler Automobile Mack II Plant

Headquartered in Wixom, Michigan, Schreiber Roofing Corporation is a fifth-generation, family-owned commercial roofing company that has been in business since 1916. When Schreiber Roofing was tapped to perform a commercial roofing project on Fiat Chrysler Automobile’s (FCA) Mack II engine plant in Detroit, MI, they chose to use Polyglass roofing products as the optimal solution for the project’s unique challenges.

As a 100-year-old roofing company with a long track record of success, Schreiber Roofing felt that Polyglass products were the best fit for the cold-weather profile of the plant.

Meeting the Challenges of a Cold-Weather Roofing Project

Located in Detroit, MI, the Mack Avenue Engine Plant Complex has been owned by the Chrysler Corporation (now FCA) since 1953, when they purchased it from the Briggs Manufacturing Co. Since 2019, the plant has been under reconstruction as the future assembly site for several models of Jeep vehicles, including the next-generation Jeep Grand Cherokee.

Schreiber Roofing was called upon to do a commercial re-roofing as part of this ongoing construction. However, the project presented several environmental challenges and restrictions to be worked through. “We were under extreme weather/temperature restrictions and needed a product that could be installed at low temperatures,” says Polyglass rep James Gosiaux. “The product had to be solvent-free, and no torches were allowed on site.”

To meet these challenges, the Schreiber team first removed the existing roof system to the steel deck, then installed multiple layers of ISO insulation and a cover board. They finished the outer layers of the roof using Polyglass Elastoflex SA V Polar Base and Elastoflex SA P Polar Cap, which are solvent-free and rated for cold temperature installation.

These low-temperature SBS roofing membranes are perfect for cold weather applications ranging from 25–60ºF (-4–16ºC). The base sheet is built with a high performance reinforced fiberglass mat for excellent dimensional stability, while the cap sheet consists of a granule surface and a reinforced polyester mat for excellent puncture and tear resistance.

Both products feature Polyglass’ patented ADESO® Dual-Compound Self-Adhered Technology, eliminating the need for torches or hot asphalt during application.

Air-Sea Forwarders Warehouse

Headquartered in Chatsworth, CA, Wilson Pacific Roofing is one of the leading roofing companies in Southern California, having completed thousands of commercial and residential roofing projects since launching in 1976.

When Wilson Pacific Roofing was contracted by Air-Sea Forwarders to re-roof their 34,000-square-foot warehouse, Polyglass roofing products were Wilson’s first choice.

“We use Polyglass for almost all of our flat reroof projects,” explains company president Rick Wilson. “Polyglass roof products are ideal for the warm Southern California climate and are versatile for any type of roof deck. We always give our clients the option of the 12, 25, or 30-year Polyglass roof systems. In this case, our client requested the 12-year two-layer Polyfresko G roof system.”

Project Needs and Challenges

Reroofing Air-Sea ForwardersAir-Sea Forwarders is an air and ocean import/export company that also administers warehousing solutions for businesses on a global scale. One of the warehouses they utilize in Southern California was in need of complete reroofing due to deterioration of the original cap sheet.

The challenge for Wilson Pacific Roofing was to install a high-quality roofing system that could stand up against the hot, dry climate while keeping the building in compliance with California’s strict Title 24 energy-efficiency standards. Thankfully, they were able to choose Polyglass products that easily exceed these minimum requirements.

The project began with the removal of all existing roof layers and an inspection of the roof structure supports. After replacing four cracked roof structure supports and several HVAC base flashings, the Wilson team began by fastening a standard glass base sheet membrane across the entire roof structure.

They then applied a Polyflex APP modified bitumen membrane over the glass base sheet to serve as a target sheet. This was followed by the application of Polyfresko G Highly Reflective White APP Cap Sheet, which features patented CURE Technology for UV stabilization and a “cool roof” effect. To better hold the cap in place, Wilson applied Polyglass PG-100 Fast-Drying Asphalt Primer to the building’s tilt-up concrete walls.

To finish out the project and complete the roof’s aesthetic, the team applied Polyglass Detail & Repair Finish to the bleed-out areas of the roof.

Shriner’s Kerack

When people think of the name “The Shriner’s,” they often think of guys with tall purple hats with tassels, riding little cycles in parades.

In reality, Shriner’s International is a 501C organization consisting of a network of regional chapters, run primarily by volunteers, that offer support and services to those in need across the US and abroad.

One of the most notable examples of the organization’s work is the many Shriner’s Children’s Hospitals spread across the country. These hospitals provide no-cost transportation and critical health care for children and families with a wide variety of health issues. Many patients’ families do not have the means to pay for such necessary and often life-saving care.

(Left to right: Shriner’s Hospitals in Portland, OR and Sacramento, CA)

In late 2019, the team at Polyglass U.S.A. Inc.’s facility in Fernley, Nevada heard a rumor that the local Shriner’s Kerack in Reno was in desperate need of roof replacement for their facility. This facility supports the local community by coordinating transportation services to the Shriner’s Children’s Hospitals in Sacramento, CA and Portland, OR.

Upon finding out this information, Polyglass Special Projects reached out to the local Shriner’s contacts — Don Hettervik and Cody Conway — to better understand the organization’s needs and challenges, and see if Polyglass could offer some professional help, whether it be design or applicable use of products or budget challenges.

Shriners Kerak in Reno, NV

After talking with Hettervik and Conway, and offering to walk the roof and review proposals, the Polyglass Special Projects team concluded that the facility needed far more than the project budget could support. The Shriner’s budget did not allow for a complete reroofing, nor did it allow for additional support to the facility’s aging structure and roof design. After closely evaluating the existing roof, building, and building usages, the Special Projects team decided it was critical to offer and provide assistance on the best means and methods to handle a more complicated reroofing project such as this.

After discussing all options with Hettervik and Conway, Polyglass offered to work with D&D Roofing, a local roofing contractor, on an entirely new roof design that would meet the Kerack’s needs. Based in Northern Nevada, D&D Roofing was founded in 1977 and is now a 100% employee-owned company. For this project, D&D Roofing came up with a new design that provided the building with a much needed new roof and included components that would strengthen the building diaphragm. They chose a multi-ply modified bitumen roof system with exceptional performance and high puncture resistance, unlike the single-ply membrane previously under consideration.

Upon removing the facility’s decades-old roofing system, it became clear that the plywood decking was not serviceable and would need replacing. The new roofing assembly included a coverboard layer of rigid gypsum-based material and Georgia Pacific’s DensDeck Prime, which was fastened to the wood with corrosion-resistant fasteners and plates to provide resistance to high desert wind loads.

Reroofing Shriners Kerak in Reno, NV

After installing the DensDeck Prime, a layer of Polyglass’ SBS self-adhesive (SA) base membrane was installed, along with Elastoflex SA Base Poly, a high-performance polyester reinforcement. As the tear-off of the existing roofing progressed each day, the crew at D&D Roofing quickly and effectively installed the coverboard and SBS SA Base to ensure the building remained in a watertight condition each day.

Reroofing Shriners Kerak in Reno, NV

To add superior weathering and puncture resistance, the D&D Roofing crew installed an SBS granulated cap sheet with a high-performance reinforced polyester mat (Elastoflex S6 G) by torching means, effectively fusing all layer of the assembly tightly as a monolithic layer resulting in 270 mils of membrane. The blended color added UV resistance and a visually attractive look to the completed roofing.

With Polyglass’ contribution by providing all the modified bitumen and related membrane accessories at no cost the Shriner’s for this project, the result was a much heavier-duty roofing system. It also allowed them to reroof the entire facility and make needed deck enhancements to the building.

For decades to come, this local Shriner’s facility can continue to provide critically needed meeting and transportation services for children and their families, giving them opportunities to no-cost medical care, as well as provide local residents in the Reno/Sparks area with a low-cost gathering place they can rent to have gatherings without the worries of the past, a troublesome leaking roof.

Waianae District Park Gym

The Waianae District Park Gym, owned by the city and county of Honolulu, is one of the most used public areas in the community. The roof protecting the gym became damaged, had leaks and electrical issues. This resulted in the closure of the gym’s second floor. Leeward Roofing & General Contracting removed the old roof and replaced it with Polyglass’ SBS multiply modified bitumen roof system. The roof was completed just before the 2018 hurricane season and the building was used as one of several evacuation centers on the island.
