Trapped moisture causing rot in roof timbers
Why it happens here
Westbourne's stone terraces were built to breathe, and spray foam seals the roof space completely. Moisture from inside the house rises into the loft, cannot escape, and settles on the rafters. Over several winters, that turns into rot.
Our approach
We remove the foam, inspect every rafter with a thermal imaging camera, and treat or replace any timber that has started to decay. We also restore a ventilation path so the loft can dry out naturally.
