Sprayed Polyurethane Foam, also known in the roofing industry as SPF, has been used as a roofing material for over 50 years.
It has a proven track record for being a dependable, long lasting and cost effective roofing system.
Sprayed Polyurethane Foam is applied as a liquid using plural-component spray equipment
to fill cracks and crevices. The sprayed on liquid expands approximately 25 times its original
volume to form a hard, closed cell, monolithic roof surface. The Polyurethane Foam dries
within seconds after being applied to the roof surface. Its expansion results in a weather
tight roofing membrane that is fully adhered to the roofing substrate.
A protective elastomer top coat is then applied over the foam. This protective top coat can be sprayed on, or applied with hand or power rollers.
Spray foam roofing systems have many advantages over traditional roofing methods.
Foam roofs are seamless.
Polyurethane foam is applied as a liquid, it flows and bonds together, creating a SINGLE monolithic membrane that covers the entire roof.
Because it is totally seamless, there are no seams or joints, which are the major source of leaks in a traditional roofing system.
Spray foam is easily applied.
The foam can be sprayed onto virtually any clean surface. Irregular, or odd shaped roofs and protrusions can be easily covered.
Lightweight and high strength.
Foam roofing systems generally weight approximately 50 lbs. per square foot. This is 50% less weight than a traditional
built-up roof that can weight 100 lbs. per square foot or more.
High insulation value.
Sprayed polyurethane foam has an R-value rating of approximately 7.14 per 1 inch in thickness.
It can provide more thermal resistance with less material than any other type of roofing insulation.
Foam roofing systems produce energy savings of 25% or greater when compared to alternative roofing systems.
