Total Silicone Roof System


– West Development Group (WDG), a leader in sustainable roofing products and practices, introduces the System 14? Total Silicone Roof System. System 14 is a comprehensive roofing solution that delivers a complete range of products, including silicone sheet goods, skylight glazing, silicone sealants and coatings, and Spray Polyurethane Foam (SPF) insulation, as well as other products for any commercial or industrial roofing situation.

WDG’s System 14 features a zero VOC coating (HSS 535) that is applied over a soy-based SPF, creating a moisture-resistant seal that is both durable and flexible. A silicone topcoat cures in a few hours; forms a seamless, self-flashing seal; resists oxidation, wind-driven rain and snow, ozone, and many chemicals; offers resistance to cracking and peeling and will not shrink or become brittle or stiff; and eliminates most tear-offs. The silicone surface can be easily reconditioned to provide years of further leak-free service.

Use of solvent-free silicone on a 100,000 square foot roof prevents the release of approximately 1,000 gallons of solvent into the atmosphere – enough petroleum to drive a family sedan around the world. Silicone roofing systems are environmentally beneficial, economically viable, and functionally equivalent to conventional petroleum-based roofing.

WDG’s exclusive R2R? process positions the company as the only roof system manufacturer to use recycled EPDM material to strengthen and enhance the physical properties of its silicone topcoat (HSS 540 R2R) for new roofing projects. Using recycled material from old roof tear-offs, the R2R process improves an array of WDG products and prevents tons of old roofing material from being tossed into landfills.

Using an SPF base with the silicone topcoat offers a long list of benefits. SPF is seamless, watertight, and lightweight. It eliminates flashing leaks, lowers installation costs, and provides for ease of maintenance. Its insulating properties can generate significant energy savings. Roof systems using these materials can often pay for themselves with energy savings within the warranty period.

System 14 comes with comprehensive warranty options up to 30 years and documentation regarding pertinent testing, codes, standards and conformance to industry standards and guidelines, including ASTM, UL, and FM.

System 14 is seamless and uses no mechanical fasteners, minimizing trouble spots for moisture penetration and roof system failure. A total silicone roof system allows expansion and contraction ratios to remain compatible and maintenance of all areas of the roof system to be the same.

Because silicon, the source material for silicone, is one of the world’s most abundant natural resources, silicone is immune to the volatile price fluctuations of petroleum. When petroleum prices rise, petroleum-based roofing systems increase in cost – affecting new roofing projects, future re-roofs and repairs.
