Suitable applications and roof types
This flashing kit is designed for pitched roof installations using standard roof tiles or slates.

The flashing accommodates the typical pitch and tile profiles found in UK residential construction. It is not suitable for flat roofs or non-standard window sizes.
- Pitched roofs with standard tiles or slates
- Domestic roof window installations
- 66x118cm VELUX windows only
- Roofs with conventional tile or slate coverings
Installation and positioning
The flashing must be installed as part of the complete VELUX window installation process. It sits between the window frame and the roof covering, creating a continuous seal that directs water away from the window opening. The flashing integrates with the tile or slate course both above and below the window opening. Installation should follow VELUX guidance to ensure the weathertight seal is achieved and maintained. Correct positioning is critical to prevent water ingress around the window perimeter.
- Install flashing during initial window fitting, not as a retrofit
- Position flashing to integrate with roof tile or slate courses
- Ensure flashing sits flush with the window frame
- Follow VELUX installation instructions for your specific roof type
Maintenance and durability
The flashing is constructed for long-term performance and requires minimal maintenance. Periodically inspect the flashing and surrounding roof area to ensure the seal remains intact and that debris such as moss, leaves, or dirt has not accumulated around the window opening. Clear any blockages to maintain proper water drainage. Check that the flashing has not lifted or shifted, particularly after severe weather or high winds. Any damage to the flashing should be addressed promptly to prevent water ingress.
- Inspect flashing annually and after severe weather
- Clear debris and moss from around the window opening
- Check that flashing remains flush and secure
- Address any damage or gaps immediately to prevent leaks
On-site tips and limitations
Ensure you have the correct flashing size for your window before ordering. This flashing is designed for standard pitched roof applications; non-standard roof pitches, unusual tile profiles, or slate installations may require specialist advice. The flashing works in conjunction with the window frame and roof covering as a complete system. Do not attempt to use this flashing with windows of different dimensions or on flat roofs. Proper installation is essential; if you are unsure about your roof type or installation method, consult VELUX technical guidance or a qualified installer.
