Installation requirements and on-site tips
Installation of this recessed flashing is required for proper weatherproofing and must be carried out carefully to ensure the watertight seal functions correctly. The flashing should be positioned to integrate seamlessly with the skylight unit and the surrounding roof structure. Ensure the timber substrate is sound and meets the F16 grade requirement before fitting. The flashing must be secured and sealed according to the manufacturer's instructions to prevent water penetration at the critical junction between the skylight and roof valley. Work should be undertaken in dry conditions to allow proper sealing and adhesion.
- Verify timber grade F16 or above before installation
- Install in dry weather conditions
- Follow manufacturer's installation instructions precisely
- Ensure proper sealing around all edges and junctions
- Check alignment with VELUX EDJ CK04 2000 unit before final fixing
Durability and maintenance
The VELUX Recessed Flashing is constructed from durable materials engineered to withstand exposure to weather and maintain its integrity over time. Once properly installed, the flashing requires minimal maintenance. Periodically inspect the flashing and surrounding roof area, particularly after severe weather, to ensure the seal remains intact and no debris has accumulated in the valley. Clear any moss, leaves or other debris that could trap moisture. Check that the flashing remains securely fixed and that the watertight seal has not been compromised.
- Inspect regularly, especially after severe weather
- Clear debris from roof valleys to prevent water pooling
- Check security of fixings and seal integrity annually
- Replace immediately if damage or deterioration is found
Limitations and important considerations
This flashing is designed specifically for VELUX EDJ CK04 2000 skylight units and should not be used with other skylight models. The 55×98cm dimensions are suited to standard pitched roof installations; non-standard roof pitches or configurations may require alternative solutions. The product is only suitable for use with timber grades F16 and above; weaker timber structures will not provide adequate support and weatherproofing. Professional installation is recommended if you are not experienced in roof work, as improper installation will compromise the watertight seal and may lead to water damage.
