VELUX EDW 410 1000Z PROFILED FLASHING AL SW
Suitable applications and roof types
This flashing is specifically engineered for pitched roofs with slate or profiled tile coverings. It is designed to work with standard VELUX roof window dimensions and should only be used with compatible VELUX window installations. The profiled design accommodates the contours of slate and tile surfaces, ensuring a secure fit and effective weatherproofing. Do not use this flashing on flat roofs, membrane-covered roofs, or with non-VELUX window systems.
- Pitched roofs with slate coverings
- Pitched roofs with profiled tile coverings
- Standard VELUX roof window installations
- Exposed roof positions requiring weathertight sealing
Installation and positioning
The flashing must be installed as part of the VELUX window installation system, integrating between the window frame and the roof surface. Correct positioning is essential to ensure the weathertight seal functions effectively. The profiled design should align with the roof covering pattern, and the flashing must be secured according to VELUX installation guidance. Improper installation or misalignment with roof tiles or slates will compromise water protection and may lead to leaks.
- Install flashing as part of complete VELUX window system
- Align profiled design with slate or tile pattern
- Ensure secure integration with window frame
- Follow VELUX installation instructions precisely
Durability and maintenance
The aluminium construction resists corrosion and weathering, providing long-term durability in exposed roof positions. Periodically inspect the flashing and surrounding roof area to ensure the weathertight seal remains intact. Remove any debris, moss, or lichen that may accumulate around the flashing edges, as this can trap moisture. Check that the seal between the flashing and roof covering has not deteriorated, particularly after severe weather or high winds.
- Inspect flashing annually for damage or deterioration
- Clear debris and organic growth from flashing edges
- Verify weathertight seal remains intact
- Address any gaps or movement immediately to prevent water ingress
Limitations and important notes
This flashing is sized for standard VELUX window dimensions and is not adjustable or suitable for non-standard installations. It is designed exclusively for slate and profiled tile roofs; use on other roof coverings may result in poor fit and water ingress. The flashing alone does not guarantee weatherproofing; correct installation as part of the complete VELUX system is essential. Do not attempt to modify or adapt the flashing, as this will void performance guarantees and may create leak points.
- Not suitable for flat roofs or membrane coverings
- Not compatible with non-VELUX window systems
- Cannot be adjusted for non-standard window sizes
- Must be installed as part of complete VELUX installation system
