Roof rot from trapped moisture in Victorian lofts
Why it happens here
Victorian terraces in Fairfield and Park Hill were built with breathable roofs and open eaves ventilation. Spray foam blocks that airflow, so moisture from the house condenses on the cold rafters and soaks into the timber. Over several winters, the rafters soften and rot.
Our approach
We remove the foam, inspect every rafter with a thermal imaging camera, and restore eaves ventilation. Where rot is found, we treat or replace the affected timber and provide photographs for your records.
