Common causes
- Bathroom or kitchen extract venting straight into the loft
- Eaves and ridge ventilation blocked by insulation or sagged felt
- Old bitumen felt instead of breathable membrane
- Recently upgraded insulation pushed tight against the eaves
How we fix it
- Rule out an actual leak first with a proper inspection
- Fit over-fascia vents or tile vents to restore airflow
- Re-route any extract ducts to vent outside through the soffit
- Recommend a breathable membrane upgrade at the next re-roof
