VELUX Standard Flashings 55x98cm EDL CK04 0000
Is this the right flashing for your window?
This flashing is specifically designed for VELUX CK04 roof windows measuring 55x98cm. Check your existing window size or specification before ordering. The EDL CK04 is engineered for pitched roof installations only and works with standard roof tile and slate coverings. If you are installing a different VELUX window size, you will need a different flashing code.
- Confirm your window is VELUX CK04 (55x98cm)
- Verify your roof is pitched (not flat)
- Check that your roof covering is standard tiles or slates
What is included and what you need to know
This is a complete standard flashing kit manufactured from aluminium. The kit provides all the components needed to seal the window frame to the roof structure. Aluminium resists corrosion, making it reliable in UK weather conditions. Before installation, inspect the flashing for any damage in transit and ensure you have the correct window size confirmed.
- Complete flashing system in one pack
- Aluminium construction for durability
- No additional sealing components included in this kit
Installation and roof preparation
Careful alignment is critical for weathertight performance. The flashing must be positioned correctly relative to both the window frame and your roof pitch. Installation involves integrating the flashing with your existing roof tiles or slates to ensure water runs away from the window frame. This is a precision job; poor alignment will compromise weather protection. If you are not experienced with roof work, consider hiring a qualified installer.
- Align flashing carefully with window frame and roof pitch
- Integrate with existing roof tiles or slates
- Ensure water drainage away from the window
- Professional installation recommended for pitched roofs
Pre-installation checks
Before you begin, verify that your roof structure is sound and that the opening is correctly sized for the CK04 window. Check that the roof pitch is suitable for standard flashing installation. Inspect the flashing on arrival for any damage. Have all necessary tools and fixings ready, and plan your work for dry weather to ensure proper sealing.
- Confirm roof opening matches CK04 dimensions
- Check roof structure is sound and level
- Inspect flashing for transit damage
- Plan installation during dry weather
