Foam trapping condensation against roof felt
Why it happens here
Hartlepool's coastal climate keeps humidity high, and foam sprayed directly onto felt stops the roof space from ventilating. Moisture condenses on the coldest surfaces, which are usually the timbers and the underside of the felt.
Our approach
We remove the foam in sections, restore the ventilation path at the eaves, and check the felt and battens for damage as we go. Where needed we treat the timbers and document the condition for your surveyor.
