Life Of Sprayed Polyurethane Roof

The uv resistance comes from the silicone layer which is added above the polyurethane foam.

Life of sprayed polyurethane roof.

If the polyurethane foam roofing materials are properly installed and coated every 10 20 years there is no calculable age limit where the foam loses its effectiveness. You have to completely remove the damaged foam and apply a new layer of spf and elastomeric coating. Spf roof system has a lifespan of about 10 to 20 years depending on how thick it is. We say probably because this system is very young and many of the first spf roofs that were installed in the late 1960 s and early 1970 s are still in service.

Best interval for recoating should be every 15 years. Recoating should be done regularly if you want to extend foam s life expectancy. Since a spray foam system consists of spray foam coating and granules after 10 20 years some of the coating and granules will naturally wear away. Plus multiple independent studies have confirmed the long life expectancy of this highly durable roofing.

A spray foam roof can be the last roofing system you ll ever need on a building. Conklin elastomeric roof coatings in fact may only need to be reapplied once to strengthen that possibility. Even severe damage is not as problematic. A 20 mil coating will last 10 years a 25 mil coating will last about 15 years and a 30 mil coating will last about 20 years.

The foam could potentially last forever and still serve as a roof.
