Repairing Spray Foam Roofs

When a foam roof gets mechanically induced damage from equipment or personnel, repairing the roof can be done easily with a caulking gun. Larger penetrations into the roof can be temporarily sealed with caulking as well, but it is recommended that the contractor should permanently seal the area with a new layer of topcoat.

Polyurethane Foam roofing can sometimes develop blisters, the most common cause of which is due to the presence of moisture. The majority of blisters do not pose a threat to the integrity of the foam roofing system. Unnecessary repair attempts can result in leaks and premature roof problems. If repairs are warranted, it should be left to the roofing contractor to properly repair them.
•Seamless: Polyurethane foam 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.
•Conforming: 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.
