VELUX Recessed Flashings W/ Installation Productions 134x98cm EDJ UK04 2000
Suitable applications and roof types
This recessed flashing is intended for pitched tiled roofs where a VELUX UK04 roof window is being installed. The 90mm recess depth is calibrated for common UK tile profiles, making it suitable for most standard clay and concrete tile installations on residential and light commercial properties. It works equally well in new build projects where the roof structure is being constructed, or in refurbishment work where a window is being retrofitted into an existing roof. The flashing creates a weather-tight seal that integrates the window frame neatly with the surrounding roof surface.
- Pitched tiled roofs with standard UK tile profiles
- New build and refurbishment projects
- Residential and light commercial applications
- Compatible with VELUX UK04 roof window systems
Installation and fitting
Installation of this recessed flashing requires careful positioning within the roof opening to ensure the 90mm recess depth aligns correctly with your tile profile. The flashing must be secured in place before the roof window frame is fitted, and the surrounding tiles need to be cut and positioned to sit flush against the flashing edges. Installation guidance documentation is provided with this product to support proper fitting. The flashing creates a weather-tight seal when installed correctly, so attention to detail during fitting is essential. If you are unfamiliar with roof window installation, professional fitting is recommended to guarantee performance and warranty compliance.
- Position flashing in roof opening before window frame installation
- Ensure 90mm recess depth aligns with tile profile
- Cut and fit surrounding tiles to sit flush with flashing edges
- Follow included installation guidance documentation carefully
- Consider professional installation for complex roof pitches or refurbishment work
Weather protection and maintenance
The recessed design of this flashing is specifically engineered to provide a weather-tight seal that protects the roof structure and window frame from water ingress. Once installed, the flashing works passively to direct water run-off down the roof surface. Periodically inspect the flashing and surrounding tiles to ensure no debris has accumulated in the recess area, as blockages can prevent proper water drainage. Check that tiles remain securely seated against the flashing edges, particularly after severe weather. The flashing itself requires no routine maintenance beyond keeping the roof area clear of moss, leaves, and other debris that could trap moisture.
- Inspect flashing and tile seating after installation and following severe weather
- Keep roof area clear of debris to maintain water drainage
- Check that tiles remain flush against flashing edges
- No routine maintenance required beyond general roof care
Limitations and important considerations
This flashing is designed specifically for the VELUX UK04 roof window format and the 1340×980mm dimensions. It is not suitable for other window sizes or roof window brands. The 90mm recess depth is calibrated for standard UK tile profiles; if your roof uses non-standard or unusual tile profiles, compatibility should be verified before purchase. Installation must follow the included guidance to ensure weather-tightness and warranty validity. This is a precision component where correct fitting is essential; improper installation can compromise roof integrity and lead to water damage.
