Roof timber rot hidden behind foam
Why it happens here
Foam seals the roof void and traps condensation against the rafters. In Throston's older homes, the timbers may already be vulnerable, and years of trapped moisture can cause rot that is invisible until the foam comes off.
Our approach
We remove the foam carefully and inspect every rafter. If we find rot, we tell you immediately and can replace affected sections. We also check ventilation so the roof can breathe again.
