Spray Foam Roofing
Spray Foam Roofs: Strong and Durable
Applying a spray polyurethane foam (SPF) roofing system can improve a building’s strength. In fact, SPF roofs have effective lifespans that can exceed 30 years.
Because SPF conforms and adheres to the surface on which it is sprayed, a strong bond forms to protect the roof. The layer of spray foam is seamless and self-flashing, which can eliminate the ability of water to seep through weak spots, such as fasteners and seams. Spray foam can be applied in a sloped manner to allow water to easily drain off the roof.
The bond that SPF forms to the roof can increase a building’s resistance to wind uplift. So during periods of high wind, a home or building with a spray foam roof generally experiences less damage than a building without SPF. A prominent spray foam consultant notes that he has found that “when added to the inside of a structure, spray foam ‘glues’ the whole building together, enhancing overall wind and pressurization resistance.”
