Fixing and buying guide

What this product is and who it is for

This is a standard tile flashing system for VELUX roof windows and Sun Tunnel systems. It is designed for builders, roofers, and experienced DIY customers installing or replacing roof windows in properties with tiled roofs. The flashing creates a weather-tight seal between the window frame and the roof surface, preventing water ingress and ensuring long-term performance. It works equally well in new build construction and refurbishment projects.

Compatibility and sizing

This flashing is sized for VELUX roof windows and Sun Tunnel systems measuring 660×1180mm (66×118cm). Before ordering, confirm your window dimensions match this specification exactly. The EDW FK06 2000 Pro+ Standard Flashing is compatible only with VELUX roof window and Sun Tunnel systems of this size. Check your existing window model number or specification sheet to verify compatibility. Using an incorrectly sized flashing will compromise the weather seal and may void the window warranty.

What is included and pre-installation checks

The kit includes the standard tile flashing and all necessary installation products required for professional fitting. Before installation, inspect the flashing for any damage in transit. Ensure your roof structure is sound, the roof surface is clean and dry, and the window opening is correctly sized and squared. Check that your roof tiles are in good condition and that you have adequate access and working space. Gather any additional tools you may need such as roofing nails, sealant, or flashing tape, depending on your specific roof construction.
