Can installation of rigid foam on roof be done in stages?
Due to condensation in our unvented vaulted ceiling, we must remove corrugated metal roofing to install rigid foam on top of the sheathing. We live in a remote area where there are no roofing contractors and very little help available. It’s winter here, icy and cold, and the tin cannot be removed easily as it was applied with silicone and tacky tape. Work can only be done for a few hours a day. Would it mitigate the condensation at this time if the tin is removed and a new layer of felt applied? Then could the application of the foam sheets, etc. be done when it warms up in a couple of months?
