Foam blocking eaves ventilation and causing condensation
Why it happens here
Most Abbey Manor Park roofs rely on a continuous ventilation gap at the eaves. Foam sprayed into that gap seals it, so moist air from the house has nowhere to escape and condenses on the cold roof felt.
Our approach
We remove the foam from the eaves first, then clear the ventilation path and check it is flowing. A moisture meter reading before and after shows the difference, and we fit ventilation trays where the gap has been permanently damaged.
