Foam blocking eaves ventilation
Why it happens here
Post-war roofs in Upton were often built with minimal ventilation, and spray foam applied right to the eaves seals off the remaining airflow. Warm moist air from the house then condenses on cold timbers, leading to rot.
Our approach
We remove the foam from the eaves and check that ventilation paths are clear. Where needed, we restore airflow in line with BM TRADA guidance, so the roof can breathe again.
