Trapped moisture and rot in roof timbers
Why it happens here
Foam sprayed directly onto the roof deck seals the ventilation path. In Whiteway's shallow lofts, warm moist air from the house rises and has nowhere to go, so it condenses on the timbers. Over a few winters the rafter feet soften and rot.
Our approach
We remove the foam, then check every rafter with a moisture meter and a boroscope inspection camera. Any soft timber is flagged before we finish, so you know exactly what needs replacing.
