Trapped moisture and rot in roof timbers
Why it happens here
Spray foam seals the roof space, preventing moisture from escaping. In Weston's damp climate, this leads to condensation on timbers and eventual rot. Older roofs often have limited ventilation to begin with.
Our approach
We remove the foam, inspect the timbers with boroscope cameras, and treat any rot. We then improve ventilation with additional vents or breathable membranes. This stops the problem from returning.
