Roof rot from trapped moisture
Why it happens here
Foam sprayed directly onto the underside of roof felt seals the roof and stops it breathing. In Broad Green's older terraces, moisture from cooking, washing and breathing has nowhere to go, so it condenses on cold timbers and starts rot.
Our approach
We remove the foam, open up the eaves ventilation and check every rafter with a thermal imaging camera. Where rot has started, we flag it early so you can get a roofer in before the structure is affected.
