Condensation trapped against roof timbers
Why it happens here
Spray foam seals the roof space, so moisture from inside the house cannot escape. On The Hoe, where outside air is already damp and salty, the condensation builds quickly and sits against rafters and battens until the timber softens.
Our approach
We remove the foam, check moisture levels in the timber, and reopen ventilation paths so the roof can dry. Where needed, we replace damaged vapour barrier with a breathable alternative suited to a coastal property.
