Pre-installation checks

Verify that the roof pitch is within the specified 30 to 60 degree range. Check that all necessary sealing materials and fixings are available before commencing work.

• Confirm roof pitch is between 30 and 60 degrees
• Check penetration opening dimensions match flashing size

Installation and water management

The flashing is engineered to direct water away from the building envelope and prevent ingress at the penetration point. Secure the flashing firmly to the timber frame structure using appropriate fixings. Ensure the flashing sits flush with the roof surface and that all joints are properly sealed to maintain watertightness. The S0122 finish treatment provides protection against harsh weather conditions.
