Installation and on-site assembly
The flashing kit comes complete with all installation products needed for assembly, reducing the need for additional materials on site. Follow the manufacturer's installation instructions carefully to ensure the flashing is positioned correctly around the window frame before securing to the roof structure. The weather-tight seal depends on proper alignment and secure fixing of all components. Take time to check that the flashing sits flush against both the window frame and the roof surface, as gaps or misalignment will compromise water protection.
- Unpack and check all components are present before starting work
- Follow VELUX installation instructions for correct positioning and sequencing
- Ensure the flashing sits flush and level around the entire window frame
- Secure all fixing points as specified in the installation guide
- Check for gaps or misalignment that could allow water ingress
Weather-tight sealing and roof integrity
The primary function of this flashing is to create a weather-tight seal that protects your roof structure from water ingress around the window opening. The flashing directs rainwater away from the window frame and back onto the roof surface, preventing damp and structural damage. Proper installation is critical to this performance. Once installed, inspect the flashing regularly, particularly after severe weather, to ensure all seals remain intact and no debris has accumulated that could trap water.
- Verify the weather-tight seal is complete before declaring the installation finished
- Check that water will run away from the window frame and back onto the roof
- Inspect regularly for any signs of water staining or damp around the window
- Clear any debris or moss that accumulates on the flashing
Maintenance and long-term performance
To maintain the weather-tight performance of your flashing, carry out routine visual inspections at least twice yearly, particularly in autumn and spring. Keep the flashing and surrounding roof area clear of leaves, moss, and other debris that could trap moisture or block water drainage. If you notice any cracks, gaps, or deterioration in the flashing seal, address these promptly to prevent water ingress. The flashing is engineered for durable performance in UK conditions, but regular maintenance will extend its service life and protect your roof investment.
- Inspect flashing twice yearly for signs of damage or deterioration
- Keep the flashing and roof area clear of leaves and debris
- Check that water drainage around the window remains unobstructed
- Address any cracks or gaps in the seal immediately to prevent water damage
