Roof timber rot caused by trapped moisture
Why it happens here
Spray foam creates a barrier that stops the roof space from breathing. In Huish's older lofts, which often have inadequate ventilation, moisture builds up and soaks into the timbers, leading to rot.
Our approach
We inspect the timbers with a moisture meter and thermal camera before we start. If rot is present, we treat it and replace any damaged sections. We also recommend improving ventilation to prevent it happening again.
