Spray foam roofing, or SPF, is sprayed on as a liquid and rises into a solid, closed-cell layer that bonds to the deck. On commercial buildings in Turon, KS, it does two jobs at once: it adds insulation value and it gives us a way to build slope into a flat roof that holds water.
The foam alone does not last in the sun. UV breaks down exposed polyurethane, so every SPF roof gets a coating over it, usually silicone or acrylic, and sometimes granules broadcast in for foot traffic areas. The coating is what you maintain over the years. Recoat it on schedule and the foam underneath keeps working.
Spraying foam is weather sensitive. Wind carries overspray onto cars and neighboring buildings, and moisture on the deck ruins adhesion. Our crew checks wind speed, dew point and surface temperature before we start and uses screening where it is needed.
SPF is also a good way to go over an existing roof after the wet areas are cut out, as long as the building code and the deck allow it. Spray foam roofing in Turon, KS pairs naturally with cool roof coating. Call (833) 441-4944 to talk it through.
