Roof rot from trapped moisture
Why it happens here
Spray foam applied directly to roof timbers seals the roof space and stops it breathing. In Norbury's damp climate, condensation builds up and timber starts to rot within a few years. Older Victorian roofs are especially vulnerable.
Our approach
We remove the foam, inspect every rafter and treat any rot we find. We then restore ventilation so the roof can breathe again. If rot is severe, we advise on structural repairs before we finish.
