Fixing and buying guide

Who this is for and what it does

This flashing is essential if you are installing or replacing a VELUX MK06 roof window on a pitched roof. It sits between the window frame and your existing roof covering, creating a weathertight barrier that stops rain and moisture reaching the roof structure beneath. The twin and combination design means you can use it for a single window installation or adapt it for multiple windows installed together, giving you flexibility in your roof window layout.

Compatibility and sizing

This flashing is designed exclusively for VELUX 78×118cm roof windows in the MK06 size. Check your existing window or planned installation size before ordering. The flashing is rated for pitched roofs with slopes up to 45°. If your roof pitch exceeds 45°, this product is not suitable. It is compatible with standard roof tile and slate coverings, which covers most UK domestic pitched roofs.

• Window size: 78×118cm (MK06 only)
• Maximum roof pitch: 45°
• Compatible with tile and slate roof coverings
• Twin and combination configuration for single or multiple window layouts

Pre-installation checks

Before fitting, measure your roof pitch to confirm it does not exceed 45°. Verify that your VELUX window is the correct MK06 size (78×118cm). Inspect your existing roof covering for damage or deterioration around the installation area; any damaged tiles or slates should be replaced before the flashing is fitted. Ensure you have adequate access and safe working conditions on the roof. The flashing must be carefully aligned with the roof pitch and integrated properly with the existing roof covering to maintain weather performance.

• Confirm roof pitch does not exceed 45°
• Check window is VELUX MK06 size (78×118cm)
• Inspect roof covering for damage in the installation area
• Plan for careful alignment during installation to maintain weathertightness
