Spray foam roofing is an admirable form of roofing for many reasons. But how long does it last? According to national estimates, twenty to thirty-five years is an appropriate estimate for spray roofing lifetime.
Ultimately, like many roofs, the overall timeline is determined by maintenance, weather, climate, and traffic. The more a roof is exposed to the elements without repairs or maintenance, for instance, will limit the overall lifetime. It is important to note that when the protective coating on a roof is removed, and the roof is cleaned and foam roofing reapplied, the new coating is essentially a new roof.
