18 Jan Seamless Spray Foam Around Penetrations
Existing asphalt roof had many leaks around roof penetrations and in membrane seams.
Roof penetrations received up to a 3″ layer of spray foam. The insulating foam reduced thermal expansion in the roof system. This roof should last over 30 years.
The roof had many roof penetrations, vents, and HVAC units which were sources of leaks
All of the leaks have been repairs with spray foam roofing. It is important to use an experienced roofing contractor who has the technical experience to install this roof system.
