Reduced loft ventilation causing condensation
Why it happens here
Spray foam blocks the airflow that older roofs rely on. In Oakengates, many Victorian and Edwardian properties have limited ventilation to begin with, so the foam makes it worse. Moisture then condenses on cold timbers.
Our approach
We remove the foam completely, check the timbers, and restore ventilation with breathable insulation and vapour barriers. We also advise on roof vents if needed.
