Fixing and buying guide

Who this is for and what it does

This flashing is for builders, roofers, and serious DIY installers fitting VELUX roof windows into pitched roofs. It is essential for any installation on slate or profiled tile roofs where a weathertight seal is critical. The profiled design accommodates the contours of slate and tile coverings, ensuring water runs away from the window frame rather than pooling or seeping beneath it.

Compatibility and sizing

The EDW 410 1000Z is engineered specifically for standard VELUX roof window dimensions. Before ordering, confirm your VELUX window model and size to ensure this flashing is the correct match. This flashing is designed for slate and profiled tile roofs only; it is not suitable for flat roofs, corrugated metal, or other roof coverings. Check your roof type and window specification against the product code EDW4101000Z to avoid incompatibility issues.

• Suitable for slate roof coverings
• Suitable for profiled tile roof coverings
• Sized for standard VELUX window dimensions
• Integrates with VELUX installation system

Material and durability

The flashing is manufactured from aluminium, which offers excellent corrosion resistance and durability in exposed roof environments. Aluminium does not rust and requires minimal maintenance over the lifetime of the installation. This material choice ensures the flashing will maintain its weathertight properties for many years without degradation.

Pre-installation checks

Before fitting, inspect the flashing for any damage in transit. Ensure the roof surface is clean and free from debris, moss, or loose tiles. Confirm that the window frame is correctly positioned and level. Have all VELUX installation components to hand, as the flashing must be integrated with the window system during installation. Follow VELUX installation instructions carefully to achieve a proper weathertight seal.

• Check flashing for transit damage
• Clean roof surface thoroughly
• Verify window frame position and level
• Gather all VELUX installation components before starting
