Fixing and buying guide

What this product is and who it is for

This is a profiled tile flashing manufactured by VELUX to seal the gap between a roof window and surrounding roof tiles on pitched roofs. It is for builders, roofers, and serious DIY installers carrying out new build or refurbishment work where a VELUX roof window is being fitted into a tiled pitched roof. The flashing ensures a weather-tight installation and professional appearance.

Compatibility and sizing

This flashing is engineered specifically for VELUX roof window systems with aperture dimensions of 1340 x 980mm (134 x 98cm). The EDW UK04 code denotes this as a standard profiled tile flashing for UK applications. Before ordering, confirm that your VELUX roof window matches these dimensions and that your roof covering is pitched tiles. The profiled design is matched to common UK roof tile profiles, so check your tile type during planning.

Pre-installation checks

Before fitting, verify that the roof aperture is correctly sized to 1340 x 980mm and that the surrounding roof structure is sound and level. Ensure the roof pitch and tile profile match the flashing design. Check that all VELUX window components are on site and undamaged. The flashing must be installed as part of the complete VELUX roof window system to achieve the weather-tight seal and performance guarantee.

• Confirm aperture dimensions match 1340 x 980mm

Installation and performance

This flashing is engineered for UK roof conditions and long-term durability when installed correctly with compatible VELUX roof window systems. The profiled design ensures seamless integration with standard roof tiles, maintaining visual consistency across the roof plane. Proper installation is essential to achieve the weather-tight seal that prevents water ingress around the aperture. Follow VELUX installation guidance and building regulations for pitched roof window installations.
