Roofing contractor NV Roofing in Chantilly, VA restored 250,000-square-feet of aged modified bitumen roof with Polyglass’ silicone roof coating system. The new coating system provides an energy efficient, water-resistant and long-term solution for the Washington DC apartment building. The NV Roofing crew first cleaned and repaired the roof before applying PolyBrite® 98 One-Part Acrylic Primer/Bleed Blocker for silicone coatings. PolyBrite® 95 Silicone Roof Coating was used to complete the system.

North Dade Regional Library
Polyglass’ premium roof system was the ideal choice for the Internal Services Department at Miami-Dade County. The County continues to rely on Polyglass’ high performing APP and SBS roof systems to meet code and energy efficiency requirements.
For the North Dade Regional Library in Miami Gardens, FL the County decided on the Polyglass three-ply modified bitumen roof system over Polyisocyanurate insulation. Roofing contractor Florida Building & Supply installed 58,000 sq. ft. of Elastoflex SA V self-adhered SBS base sheet, Polyflex® Smooth mid-ply and Polyfresko® G torch-applied cap sheet. Polyfresko G was used as the flashing up and over the top of the parapet wall followed by a coping detail.
Roof System Benefits:
- ADESO® Self-Adhered Technology allowed for quick dry-in of the building and enabled the library to remain open during the roof work.
- CURE Technology®—a thin-film added to Polyfresko G membranes during manufacturing—protects the membrane from premature deterioration and granule loss.
- The three-ply system provides a dependable solution with multiple layers for redundancy.
- Polyflex and Polyfresko G are polyester reinforced APP membranes, providing additional tear strength and puncture resistance to the roof system.
Edgewood Terrace
Edgewood Terrace Commons IV, a 258-unit high-rise building in Washington DC, was reroofed with Polyglass’ multi-ply roof system. The 25,000 sq. ft. roof had severe ponding issues and held water after heavy rainfalls and snow storms.
To solve the roof challenge, roofing contractor DC Duct & Sheet Metal LLC tore off the existing system down to the concrete deck and created a tapered design to ensure positive drainage. The tapered insulation was adhered to the deck followed by cover board and Polyglass’ high performing three-ply roof system. Products included two-plies of Polyglass’ Elastoflex SA V self-adhered base sheet and Polyflex® G torch-applied cap sheet in white.
To seal the large number of penetrations, the roofing crew used PolyFlash® 1C, a one-component, liquid flashing compound that can be used to seal roofing and waterproofing details such as walls, curbs, vents, roof drains, pitch pans and unusually shaped penetrations.
Encore Custom Preforms
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.
