VELUX Standard Flashings 55x118cm EDL CK06 0000
Is this the right flashing for your window?
This flashing is specifically designed for VELUX roof windows with dimensions of 55×118cm. Check your existing window size or specification before ordering. The flashing is suitable for pitched roofs with a maximum pitch of 55°. If your roof pitch exceeds 55° or your window is a different size, you will need a different flashing model.
- Window size must be 55×118cm
- Roof pitch must not exceed 55°
- Aluminium construction suits most UK roof conditions
What you are buying
You are purchasing one standard aluminium flashing unit designed to fit around the perimeter of your VELUX roof window. The flashing bridges the gap between the window frame and the roof surface, creating a seal that directs water away from the window opening and down the roof slope.
- One flashing unit per order
- Aluminium material for durability and corrosion resistance
- Standard profile for straightforward installation
Before you install
Ensure your roof structure is sound and the opening is correctly sized for a 55×118cm window. The flashing must sit flush against both the window frame and the roof surface. Check that your roof pitch does not exceed 55°, as the flashing is not designed for steeper angles. Have the window frame ready for installation and ensure you have appropriate roofing materials (slates, tiles, or other covering) to complete the weathertight seal around the flashing edges.
- Verify window opening dimensions match 55×118cm
- Confirm roof pitch is 55° or less
- Prepare roof covering materials for final seal
- Ensure roof structure is structurally sound
Installation overview
The flashing is installed as part of the window installation process. It sits between the window frame and the roof structure, with the roof covering (tiles or slates) laid over the top edge of the flashing to complete the weathertight seal. Follow VELUX installation instructions carefully to ensure the flashing is positioned correctly and all edges are properly sealed and covered.
- Install flashing as part of window installation sequence
- Position between window frame and roof surface
- Roof covering must overlap flashing edges
- Ensure all joints are sealed
