Sprayed Polyurethane Foam has been used as a roofing and insulation material for over 45 years. Today there are foam roofs that have been in place for decades, and they should last indefinitely as long as they are properly maintained.
Because the foam is sprayed onto the roof as a liquid, it forms a single continuous structure that is seamless and very stable.
Foam roofing produces energy savings of 30% or more when compared to alternative roofing systems. The cost of the roof can be easily recovered in under five years, through these energy savings alone.
Foam roofing has many advantages over traditional roofing. Here are some examples:
Seamless: Polyurethane foam is applied as a liquid, creating a single monolithic membrane that covers the entire roof. There are no seams or joints, which are the source of the majority of leaks in traditional roofs.
Flexible: The foam can be sprayed onto virtually any surface, so irregularly shaped roofs and protrusions are readily taken care of.
Lightweight: Foam roofing typically weighs around 50 lbs. per square foot, versus 800 lbs. for a built-up roof and 100 lbs. for ballasted single-ply roofs.
Thermal Insulation: SPF has the best insulating properties available for commercial construction today.
Sustainability: Foam roofs require a minimum of upkeep, creating little waste, and they have an indefinite lifespan.
