Actually when elastomeric roof coatings are reapplied at strategic intervals on top of it spray foam roofing has been shown to last up to 50 years.
Life of sprayed polyurethane roof.
A spray foam roof can be the last roofing system you ll ever need on a building.
Plus multiple independent studies have confirmed the long life expectancy of this highly durable roofing.
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.
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.
Conklin elastomeric roof coatings in fact may only need to be reapplied once to strengthen that possibility.
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.
Sprayed polyurethane foam also referred to as spf probably has the longest roofing system lifespan in the study.
Spray polyurethane foam roofing does not last.
The uv resistance comes from the silicone layer which is added above the polyurethane foam.
Even severe damage is not as problematic.
Spf roof system has a lifespan of about 10 to 20 years depending on how thick it is.
Best interval for recoating should be every 15 years.
Recoating should be done regularly if you want to extend foam s life expectancy.
