Fixing and buying guide

What this product is and who it is for

This is a recessed tile flashing for VELUX FK06 roof windows. It is for builders, roofers, and serious DIY installers who are fitting a VELUX FK06 roof window into a pitched tile roof and need a professional, weather-tight installation. The recessed design means the flashing sits below the tile line, creating a neat finish rather than a raised profile. It is suitable for both new build projects and refurbishment work on existing pitched tile roofs.

Compatibility and sizing

This flashing is specifically designed for VELUX FK06 roof window systems only. The flashing dimensions are 660 × 1180mm with a flashing depth of 90mm. You must confirm your roof window is an FK06 before ordering, as flashings are not interchangeable between VELUX window sizes. Check your existing window documentation or the window frame itself for the size designation.

• Compatible with VELUX FK06 roof windows only
• Flashing dimensions: 660 × 1180mm

Pre-installation checks and roof preparation

Before fitting, inspect your pitched tile roof to ensure it is in sound condition. The roof structure must be able to support the window and flashing weight. Check that the roof opening is correctly sized and that surrounding tiles are not damaged or loose. Ensure you have adequate access and working space on the roof. The flashing is designed for pitched tile roofs; do not use on flat roofs or other roof types. Have all VELUX FK06 window components and installation instructions to hand before beginning work.

Installation and weather-tight sealing

The recessed design of this flashing is engineered to create a weather-tight seal when installed correctly. The 90mm depth allows the flashing to sit below the tile line, with surrounding tiles overlapping the flashing edges to shed water away from the window frame. Follow VELUX installation instructions carefully to ensure proper seating and sealing. Pay particular attention to the junction between the flashing and roof tiles, as this is critical to preventing water ingress. Use appropriate sealants and fixings as specified in the VELUX installation guide. The flashing must be installed before the roof window frame is fitted.

• Flashing must be installed before the roof window frame
• Recessed design allows tiles to overlap flashing edges
• Follow VELUX installation instructions precisely
• Ensure weather-tight seal at all flashing junctions
• Use sealants and fixings as specified by VELUX
