Gentech Roofing is a family-owned business that has served the industrial and commercial roofing needs of the Greater Toronto Area for more than 35 years. As winners of the Toronto Star Reader’s Choice Award in 2018 and 2020, they have built a solid reputation in the community for bringing stellar workmanship and service to every project they undertake. When Stonegate Dental in Guelph, ON, contracted Gentech to install a new roofing system on their facility, it came as little surprise that Polyglass was their product line of choice.
Project Needs and Challenges
Embarking this project, Gentech faced the challenge of tearing out the old 4-ply BUR roofing system and laying down a new waterproof layer in a short amount of time. They also needed to minimize their impact on the dental office and other tenants who needed to continue conducting business while construction was underway.
To meet these challenges, Gentech installed Polyglass’ Stick 1 Torch 1 roofing system, a 2-ply modified bitumen system consisting of a self-adhered (SA) Elastoflex SA base sheet and a torch-applied Elastoflex S6 G 4.0 HP cap sheet installed over 2-inch ISO boards. Thanks to its ability to adhere directly to the ISO board with minimal effort, the Gentech workers could quickly apply the single-ply base sheet layer to make the roof watertight while allowing tradespeople to carry on work inside the building below. This quick installation reduced the total man-hours for the install by at least an hour and a half for each man.
Watch the Polyglass time study to see the labor-saving benefits of the Stick 1 Torch 1 system when compared with a 2-ply torch-applied roofing system:
The Stick 1 Torch 1 roofing system also allowed for a much cleaner and less intrusive roofing installation, with no asphalt ribbons, no over pours, and no strong odors to inconvenience Stonegate Dental’s patients. For the Gentech contractor on-site, the installation’s primary benefit was its safety as the Stick 1 Torch 1 system does not need hot asphalt for its application. He also found it to be more cost-effective, with no need for propane or the hiring of additional resources to operate the asphalt kettle.
Polyglass Product Spotlight
Gentech utilized the following Polyglass products with the Stick 1 Torch 1 system installed on the Stonegate Dental building:
- Elastoflex SA Base is a flexible yet highly tear-resistant modified bitumen membrane featuring ADESO® dual-compound self-adhering technology and finished lay lines for easy and accurate installation. When used in conjunction with an approved Polyglass cap sheet, Elastoflex SA Base provides exceptional waterproofing properties. It allows for a fast and clean installation without the need for torches, hot asphalt, or separate bonding adhesives.
- Elastoflex S6 G 4.0 HP is a high-performance Styrene-Butadiene-Styrene (SBS) cap sheet ideal for multi-layer low-slope roofing assemblies. When used as part of a high-quality multi-ply roofing system, it adds a strong layer of waterproofing and can be easily applied to the base via torch heat welding or cold adhesives.

Project Overview:
Encore Custom Preforms produces more than 84 different types of plastic bottles at its Mississauga, Ontario facility for companies across North America. When the 20,000 sq.ft. built-up roof (BUR) on the facility needed to be replaced in 2016, the company hired Cherry Roofing to inspect and recommend a new roof system. A seasoned roofing contractor serving the Greater Toronto Area since 1979, Cherry Roofing selected a hybrid BUR. Cherry Roofing used Polyglass’ multi-ply SBS (Styrene-Butadiene-Styrene) membranes to provide long-term waterproofing protection. With a 20-year warranty, the new roof system will protect the building and assets for years to come.
The Roof System:
After removing the existing BUR and cleaning the steel deck, Cherry Roofing adhered a Kraft vapor barrier to the deck. The 1.5” polyisocyanurate insulation was hot-mopped over the vapor barrier followed by the installation of 1/2” fiberboard. The crew hot-mopped two plies of Elastoflex S6, a SBS base sheet reinforced with a polyester mat and saturated with a rubberized asphaltic compound to increase durability. The roof system was finished with a top flood coat of asphalt followed by a pea gravel pour. Elastoflex S6 G Oak, a premium SBS cap sheet reinforced with a non-woven 250 grams polyester map, was torch-applied to the perimeter flashing.

Onyx Roofing, a residential and commercial roofing contractor based in Vaughan, Ontario, reroofed a 35,000 sq.ft. warehouse building in Vaughan, Ontario using Polyglass’ multi-ply system. Products included Elastoflex® V 2.2., a high quality, fiberglass reinforced, SBS (Styrene-Butadiene-Styrene) modified bitumen roofing membrane. For the weathering surface, Onyx Roofing chose Elastoflex® S6 G 250 cap sheet in Oak. Elastoflex S6 G is a SBS modified bitumen membrane reinforced with a non-woven 250 grams polyester mat. The cap sheet is available in 10 colors.
Roofing Contractor Ainger Group upgrade the roof of 20 homes on the Canadian Airforce Base in Trenton, Ontario. Polyglass’ Elastoflex® SA P Gray Slate, a self-adhered cap sheet was selected for the 400 sq.ft. flat part of the roofs. The cap sheet was a perfect match for the shingles and are available in 10 colors.
The 18,000-square-foot low slope rooftop was reroofed beginning with installing Elastoflex® SA V base sheet which features ADESO® Technology. Manufactured with a strong, fiberglass mat reinforcement, Elastoflex SA V exhibits excellent dimensional stability that made it an ideal base ply for the extreme climate. After the Elastoflex SA V was installed, Concord adhered the Elastoflex SA P cap sheet directly over top of the base sheet. To seal the seams and end laps of both the SA V and SA P membranes, Concord utilized Polyglass’ innovative SealLap® and FastLap® technologies.
For its steep slope roof portion, Polystick® TU Plus was used under the metal roof tiles.
