I''m having trouble finding a solar installer who can install panels on our flat foam roof. My house has two roof types: Per a home inspector, we have about 8 years of life remaining for the asphalt shingles.

Foam insulation, with its superior properties, ensures that the energy your solar panels generate isn''t wasted. This energy-efficient insulation creates an air barrier, minimizing heat transfer

Yes, you can install over foam as that''s how most commercial roofs are made, but it''s not nearly as straight forward as bolting to rafters. They''re just nervous about anything outside the norm

This is key as it is not advised to install the PV panels directly onto the spray foam roof surface. The reason direct application is ill advised is that solar heat and water may accumulate
