Fixing and buying guide

What this product is and who needs it

This is a roof window flashing kit for integrating VELUX windows into pitched tile roofs. It is designed for builders, roofers, and serious DIY installers who are fitting or replacing a VELUX roof window and need to ensure a weather-tight seal. The flashing bridges the gap between the window frame and the surrounding roof tiles, preventing water from running behind the tiles and into the roof structure. The grey colour and profiled design mean it sits flush with standard tile profiles for a professional appearance.

Compatibility and sizing

This flashing is sized at 1340×1600mm and is designed for compatible VELUX roof window systems. Before purchasing, confirm that your VELUX window model is compatible with the EDW UK10 2000 flashing and that your roof pitch and tile profile fall within the range this flashing is designed to accommodate. The dimensions given are the overall flashing size; check your roof layout and window opening to ensure this size suits your installation.

What is included and pre-installation checks

This is a single flashing unit that comes complete with the BDX 2000 bracket for mounting to your VELUX window frame. Before installation, inspect the flashing and bracket for any damage in transit. Ensure your roof structure is sound, the window opening is correctly sized and positioned, and that you have the correct VELUX window model on site. Check that your roof tiles and battens are in good condition and that you have adequate access and safety equipment for working at height.

Installation and weather performance

The profiled design of this flashing is engineered to match standard roof tile profiles, allowing it to sit neatly between tiles without gaps or overlaps that could compromise the weather seal. The flashing must be secured using the included BDX 2000 bracket, which anchors it to the window frame. Proper installation is critical to prevent water ingress; follow VELUX installation guidance carefully, ensuring all joints are sealed and the flashing is fully supported by the roof structure. This flashing is built to perform reliably in typical UK weather conditions including rain, wind, and temperature variation.
