Flat roof replacement completed in Quinton 🔨🏠
This property was suffering from a failed, sweating GRP flat roof caused by inadequate ventilation. We stripped it back and rebuilt it properly from the ground up to ensure long-term performance and airflow.
Works carried out:
▪️Stripped failed GRP flat roof back to timber joists
▪️Rectified missing insulation 🔥
▪️ Installed cross batten system with over-fascia vent for maximum airflow
▪️ Fitted 18mm tongue & groove OSB decking
▪️Installed 3-layer high-performance felt system:
• Base layer mechanically fixed with 20mm galvanised clout nails
• 2mm torch-on film-on-film intermediate layer
• 4mm charcoal mineral cap sheet
▪️Installed 6 mushroom vents to maximise ventilation in the cold deck roof
A properly ventilated flat roof means no trapped moisture, no sweating, and a much longer lifespan 👌
