Fixing and buying guide

What this product is for

This combi flashing kit is designed specifically for installing VELUX roof windows on pitched roofs that use slate and tile materials. The kit provides the weatherproofing interface between the window frame and your roof covering, preventing water ingress around the window opening. It is suitable for both new installations and replacements where your roof combines slate and tile elements or where material choice flexibility is needed.

Compatibility and sizing

The EKW MK08 2021M measures 780mm wide by 1398mm high and is engineered for standard pitched roof pitches. Before ordering, confirm that your VELUX roof window is compatible with the MK08 flashing size and that your roof pitch falls within the standard range this kit is designed for. The combi design works with both slate and tile roof materials, so you do not need to determine which separate flashing type your roof requires.

• Dimensions: 780mm × 1398mm
• Suitable for pitched roofs with slate and tile materials
• Combi design eliminates need for separate slate or tile flashing products

Installation overview

The VELUX combi flashing kit is fitted around the roof window frame to create a weathertight seal with your slate or tile roof covering. The single-unit design simplifies the process compared to fitting separate flashings. Follow VELUX installation instructions carefully, ensuring the flashing is correctly positioned and secured to create a continuous water barrier. Proper sealing and fixing are essential for long-term weatherproofing performance.
