Sprayed polyurethane foam also referred to as spf probably has the longest roofing system lifespan in the study.
Life of sprayed polyurethane roof.
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.
You have to completely remove the damaged foam and apply a new layer of spf and elastomeric coating.
Best interval for recoating should be every 15 years.
Spray polyurethane foam roofing does not last.
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.
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.
The uv resistance comes from the silicone layer which is added above the polyurethane foam.
Spf roof system has a lifespan of about 10 to 20 years depending on how thick it is.
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.
A spray foam roof can be the last roofing system you ll ever need on a building.
The foam could potentially last forever and still serve as a roof.
Even severe damage is not as problematic.
