Spray Foam Roofing

What This Service Involves

Spray polyurethane foam roofing is applied as a liquid that expands into a rigid, seamless layer bonding tightly to the existing deck and every penetration it surrounds. That self-flashing quality is a real advantage on the complicated Northwest commercial roofs cluttered with curbs, pipes, and HVAC units where seams and flashings usually fail first. The foam adds significant insulation value while its sprayed application can build slope into ponding-prone low spots without a full tear-off. We top the foam with a protective silicone or acrylic coating that shields it from UV and renews easily to extend the roof's life for decades.

Benefits

Seamless, self-flashing surface eliminates common leak points; Added insulation improves the building's energy performance; Sprayed slope can correct ponding without full tear-off; Lightweight system adds minimal load to the structure; Renewable coating extends service life with simple recoats

Our Process

1) Clean and prepare the deck to ensure strong foam adhesion; 2) Spray polyurethane foam to the specified thickness and slope; 3) Inspect the cured foam and address any surface imperfections; 4) Apply protective coating with embedded granules for durability

What Affects the Cost

Foam thickness and the coating system specified; Roof size and the density of penetrations to encapsulate; Condition and cleanliness of the existing substrate; Slope correction required to eliminate ponding areas; Future recoat schedule factored into lifetime value

Best Time of Year

Foam and coatings require dry surfaces and mild temperatures, so we apply spray foam roofing during stable summer weather.
