Spray foam blocking loft ventilation
Why it happens here
Older Wrockwardine roofs rely on airflow through eaves and ridge vents. Spray foam applied to the underside of roof felt seals these gaps, trapping moist air inside. Over time, this leads to condensation, damp timbers, and mould.
Our approach
We remove the foam, clear the vents, and check the roof space is breathing properly again. Where needed, we install additional ventilation trays to prevent the problem returning.
