Protecting Your Roof Edge in Three Steps

Prepare Wall & GRP

Ensure parapet wall is level and clean. GRP membrane should extend to wall edge, ready for coping placement with proper bedding mortar.

Set Cast Coping

Bed coping stones on mortar. The drop lip overhand extends beyond the membrane edge by 20mm minimum, creating an essential water barrier.

Long-term Protection

Drop lip diverts water away from GRP edge. Drip groove prevents capillary action, staining, and membrane deterioration for years.
