Fixing and buying guide

Who this product is for

This flashing is for builders, roofers, and experienced DIY installers fitting VELUX EDL SK01 2000 skylights into slate roof applications. It is not suitable for other skylight models or roof types such as tile, felt, or metal roofing. You should have competence in roof work and skylight installation before attempting this project.

Compatibility and sizing

This flashing is manufactured exclusively for the VELUX EDL SK01 2000 skylight model. The 114 x 70mm dimensions are fixed and designed for standard skylight positioning on slate roofs. Before purchase, confirm your skylight model matches exactly and that your roof structure can accommodate this size opening. The integrated BDX 2000 component is included and pre-fitted, so no separate flashing kit is required.

• Size: 114 x 70mm
• BDX 2000 flashing component included

Pre-installation checks

Before fixing, inspect the flashing for any damage to the slate or edges. Ensure your roof opening is correctly sized at 114 x 70mm and that the surrounding slate tiles are in good condition and properly secured. Verify that your VELUX EDL SK01 2000 skylight frame is ready for installation and that you have appropriate roof access and safety equipment in place. Check weather conditions—do not install during heavy rain or high winds.
