What is Spray Foam Roofing?
Spray Foam roofing is a two-component spray applied polyurethane roofing foam that provides insulation, waterproofing and roofing stability.
Polyurethane foam roofing has the highest R-value of any commonly used roof insulation. Total payback of your new roof usually occurs in less than ten years through savings in heating and cooling costs. Since your new roof is spray-applied, it can conform to any irregularity and will seal all penetrations, flashings, parapet walls, even wall capping.
This system provides:
►Seamless roof membrane.
►No fasteners-fully adhered.
►Easily tapered to eliminate ponding water.
►Tear off is not normally required.
►UL and FM fire and wind rated.
Polyurethane roofs are installed quickly, resulting in a lower labor cost and less interruption. When considering the many variables in a re-roofing project, the versatility of a polyurethane roof makes it a logical and cost effective solution. Spray Foam roofing makes complex shapes easy to spray and can be applied to metal, asphalt, clay and wood roofs.
Can Spray Foam Roofing Withstand Weather?
Spray Foam roofing can withstand extreme weather conditions, but requires a protective coating. Under direct sunlight, the polyurethane will degrade at a rate of approximately1/16 inch per year. To protect it from U.V. damage, various types of elastomeric rubber membranes are installed. Among the membranes used are silicones, urethanes, polyureas, acrylics, and butyls. These coatings are spray applied over the polyurethane, forming a seamless protective membrane. In addition to U.V. protection, these coatings provide waterproofing, impact resistance, and improved fire ratings. Additional membranes include more conventional types such a EPDM, Modified Bitumen, and Built Up.
Spray Polyurethane Roofing is designed to be relatively maintenance-free but basic maintenance that requires cleaning and recoats every 10-20 years will help maintain the roofing foam in order to keep the structure properly insulated.
