Fixing and buying guide

Who this is for and what it does

This flashing kit is for builders, roofers, and experienced DIY installers fitting a VELUX roof window into a pitched tile or slate roof. The kit provides the weatherproof interface that prevents water ingress around the window opening. It is not a standalone product and must be used as part of a complete VELUX roof window installation.

Compatibility and sizing

The EDW SK08 2000 designation indicates this kit is sized for the SK08 window category and roof specifications up to 2000mm. You must verify that this flashing kit matches your specific VELUX roof window model before purchase, as different window sizes and types require different flashing kits. The kit is designed for pitched roofs with slate or tile coverings within standard UK roof pitch ranges. Check your window documentation or contact VELUX to confirm the correct flashing kit for your installation.

• Confirm your VELUX window model number before ordering
• Suitable only for slate and tile roofs, not for other roof coverings
• The BDX connector is integrated into this kit for straightforward assembly

What is included and pre-installation checks

This kit contains the single tile flashing frame and integrated BDX connector as a complete assembly. Before installation, inspect all components for damage and ensure you have the correct kit for your window model and roof type. Check that your roof opening has been cut to the correct size and that the surrounding roof structure is sound and ready to receive the flashing.

• Unpack and inspect all components for transport damage
• Verify the kit matches your VELUX window model documentation
• Ensure the roof opening is cut to the correct size for this flashing kit
• Check that roof tiles or slates around the opening are in good condition

Installation guidance

Installation must follow VELUX fitting guidelines to ensure a weatherproof seal and proper performance. The flashing frame must be carefully aligned with existing roof tiles and integrated with the roof structure so that water is shed correctly. The BDX connector provides the interface between the flashing kit and your VELUX window frame. If you are not experienced in roof work, engage a qualified roofer or VELUX installer to carry out the work, as incorrect installation can lead to water leaks and structural damage.

• Follow VELUX installation instructions supplied with the window and flashing kit
• Ensure precise alignment with existing roof tiles or slates
• Use appropriate sealants and fixings as specified in VELUX guidance
• Consider engaging a qualified roofer if you are unfamiliar with roof work
