Fixing and buying guide

Who this product is for

This flashing is intended for builders, roofers, and experienced DIY installers fitting VELUX CK06 roof windows into pitched roof structures. It suits projects where a streamlined installation approach is preferred, as the combination design minimises the number of flashing components to handle and fit.

What is included and pre-installation checks

This product is a single twin and combination flashing unit. Before installation, inspect the flashing for damage or defects. Ensure the roof opening is correctly sized and prepared to CK06 specifications, and verify that the surrounding roof structure is sound and ready to receive the window and flashing assembly. Check that all necessary sealants and fixings are available separately if not supplied with your window kit.

Installation overview

The combination flashing integrates both upper and lower weatherproofing functions, reducing installation steps compared to separate flashing components. Position the flashing around the CK06 window opening, ensuring it sits flush with the roof plane and overlaps correctly with roof covering materials. Proper sealing and fixing are essential to prevent water ingress. Refer to VELUX installation instructions specific to the CK06 window and this flashing type for detailed fitting procedures.
