VELUX Standard Flashings 78x118cm EDW MK06 0000
Suitable applications and roof types
This flashing is designed exclusively for timber roof substrates graded F16 and above. It is not suitable for metal or concrete roof structures. The flashing accommodates VELUX EDW MK06 rooflights measuring 78x118cm and integrates with the window frame to provide a complete watertight seal at the roof penetration. It can be used in both new roof installations and retrofit applications where a compatible VELUX rooflight is being fitted.
- Timber roofs only, graded F16 and above
- Not suitable for metal or concrete roof substrates
- Designed for VELUX EDW MK06 78x118cm rooflights
- Suitable for new build and retrofit installations
Installation and positioning
The flashing must be positioned around the rooflight opening before the window frame is fully secured. It sits between the roof structure and the rooflight frame, creating a continuous seal that directs water away from the opening. Proper alignment with the rooflight dimensions is essential, as the 78x118cm size is specific to the EDW MK06 model. Installation should follow VELUX guidance to ensure the flashing sits flush and level with the surrounding roof surface.
- Position flashing around rooflight opening before final frame fixing
- Ensure flashing sits flush with surrounding roof surface
- Align carefully with 78x118cm rooflight dimensions
- Check that all edges are properly sealed and secured
Durability and maintenance
The powder-coated plastic finish is engineered to resist corrosion and weathering, providing long-term protection in exposed roof conditions. Regular inspection is recommended, particularly after severe weather or high winds, to ensure the seal remains intact and no debris has accumulated around the flashing edges. The plastic material does not require painting or specialist maintenance, though any accumulated moss or debris should be gently cleared to maintain water drainage.

Important limitations and compatibility
This flashing is engineered specifically for the VELUX EDW MK06 rooflight model and the 78x118cm size. It cannot be used with other rooflight models or sizes, as dimensional compatibility is critical for the watertight seal. The flashing is designed for timber roof substrates only and will not provide an effective seal on metal or concrete roof structures. Ensure your roof timber is graded F16 or above before installation.
- Compatible with VELUX EDW MK06 rooflights only
