Spray Foam Roofing
Whether you are currently planning new construction or reroofing an existing roof, Sprayed Polyurethane Foam Roofing is probably for you. This is because it lends itself well to all types of roofing situations, from traditional flat roofs to unusual designs. Foam roofing systems can be applied rapidly, with little or no disruption to the facilities. In most reroofing situations there is not even a need to remove the existing roof.
Spray foam roofing is typically a 2.7-3 lb density foam with a protective coating applied to protect the foam.
Here are the main benefits of spray foam roofing:
Seamless: Polyurethane foam and the protective coatings is applied as a liquid, creating a single monolithic membrane that covers the entire roof. There are no seams or joints, the source of the majority of leaks in traditional roofs.
Flexible: The foam can be sprayed onto virtually any surface, irregularly shaped roofs and protrusions are readily taken care of.
Lightweight: Foam roofing typically weighs around 50 lbs. per square, 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: Foamed roofs require a minimum of upkeep, creating little waste and have an indefinite lifespan. Sprayed polyurethane foam has an R-value of 7 per 1 inch thickness, enabling it to provide more thermal resistance with less material than any other type of roofing insulation. Repairs are easily made by in house maintenance staff with caulking.
The Superdome in New Orleans was damaged once in a severe hail storm. Thousands of hairline cracks appeared in the top coat, but no leaks ever occurred, even though it wasn’t repaired for over a decade! If a penetration does occur all the way through the foam layers, the water infiltration will be isolated only to the area where the membrane has been penetrated. Small penetrations in foam roofng systems can be repaired easily with an elastomeric caulk, reinstating the integrity of the system.
