Cherry Roofing installed a new hybrid built-up roof (BUR) system on the Maxxit Systems building in Mississauga, Ontario. Maxxit Systems designs and develops interior and exterior environments for retailers, grocery stores, restaurants and automobile dealerships. The 20-year roof features Polyglass’ multi-ply SBS (Styrene-Butadiene-Styrene) membranes and will provide long-term performance for the facility where a team of creative thinkers bring design ideas to reality.
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 Air force 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.
Roofing Contractor 3-D Roof System installs Polyglass’ Vegetative Roof atop the SHAG (Senior Housing Assistance Group) Lynnwood, Wash. property. Backed by a 30-year warranty, the three-ply modified bitumen system chosen provides the critical waterproofing needed for a vegetative roof assembly. At 500-mils thick, the system adds layers of defense for the roof and enables long-term performance. In comparison, singly ply membranes typically have a 60 mils total thickness.
Products include two layers of Polyglass’ Polyflex® Smooth APP (Atactic Polypropylene) modified bitumen membrane for the base and interply sheets. For the final layer, Polyflex® G White APP cap sheet was installed to provide resistance to punctures, tears, abrasion, foot traffic and the elements. Elastoflex SA V—a high performing self-adhered membrane featuring Polyglass’ ADESO® Technology was used for the flashing details.
Challenges:
3-D Roof Systems began the roof installation in October 2016, which according to the Seattle Times had record breaking rainfall. But 3-D Roof Systems was prepared for the inclement weather. The team used a system of inflatable tenting adapted for use on the roof to work around the weather. As they completed sections of the roof, the tent was moved to new areas that needed to be worked on.
Fort Belvoir Military Base, located in Northern Virginia, is now home to a Polyglass multi-ply modified bitumen roof system. NV Roofing proposed the Polyglass system to replace a 60,000 square foot aged TPO roof. The new roof system features mechanically attached Polyglass G2 Base sheet, heat-welded Polyflex® smooth interply sheet and heat-welded Polyflex® G granulated cap sheet in white. The redundancy of a multi-ply roof system results in a longer roof service life and return on investment for the building owner.
Overview Joseph Caleb Daycare, an early childhood education center in Miami, Fla., gets a new self-adhered, modified bitumen roof system. Roofing contractor Florida Building & Supply removed the existing failing roof and installed Polyglass’ roof system featuring CURE Technology® and ADESO® Technology. The daycare center, which caters to over 160 children, remained open during the roofing project.
Challenges The project required an energy efficient roofing solution that also complied with the South Florida wind resistance requirements for high velocity hurricane zones. Furthermore, the building owner preferred a roofing solution that did not release fumes and odors during installation, narrowing the options available. Polyglass’ self-adhered modified bitumen roof system was a perfect fit for this project because of its high reflectivity, durability and ease of installation. In addition, waterproofing the existing skylights presented a challenge because they were irregular shaped. Polyglass’ PolyFlash 2C, an odor free, liquid flashing system was applied to the skylights to form full closure.
Roof System Components The 20,000 sq. ft. roof features Polyglass’ three-ply, self-adhered modified bitumen roof system with a 20 year roof systems warranty. System components include:
Elastoflex SA V, a self-adhered SBS modified bitumen membrane. This membrane was used for the base and interply sheets.
Polyfreskco G SA, a white, self-adhered APP modified bitumen membrane was used for the surface layer of the roof system. Polyfresko G SA cap sheet is manufactured with CURE Technology, a thin-film technology that improves the membrane’s durability, UV and stain resistance, and granule adhesion.
Polyflash 2C, an odor free, UV-stable fluid-applied flashing system was used to waterproof the skylights.
