Trapped moisture and rot in roof timbers
Why it happens here
Foam sprayed between rafters seals the roof space, so moisture from the house cannot escape. On Bear Flat's hillside, driving rain adds to the problem, and timbers stay wet for months before anyone notices a smell.
Our approach
We map wet zones with a thermal imaging camera and moisture meter before removal, strip the foam carefully, and treat affected timbers with sealant. Ventilation paths are reopened so the roof can dry properly.
