Spray foam blocking loft ventilation
Why it happens here
A lot of foam in Telford and Wrekin was sprayed directly onto the roof felt rather than between the rafters. That seals the gap at the eaves where air should move. Moisture builds up, the felt stays wet and the timbers start to suffer.
Our approach
We remove the foam and reopen the ventilation path at the eaves. Then we check the felt and timbers and tell you whether the roof needs anything else before new insulation goes in.
