How and where to use guide
VELUX EDL PK04 2000 SLATE FLASHING KIT + BDX
Typical applications and installation locations
This flashing kit is designed for use on pitched slate roofs where roof penetrations require weathertight sealing. Common applications include VELUX skylight installations, chimney flashings, and other roof penetrations on domestic and commercial properties. The 2000mm length accommodates standard roof widths and penetration sizes. The kit works by creating a continuous seal between the slate roof surface and the roof penetration, preventing water ingress at vulnerable points. Installation should occur during initial roof construction or when replacing existing flashings on slate roofs.
- Skylight and roof window installations on slate roofs
- Chimney flashings on pitched slate roofs
- Roof penetrations for pipes, vents, and ducts
- Suitable for both new build and renovation projects
- Standard applications on domestic and light commercial pitched roofs
Installation and fixing with the BDX bracket
The BDX bracket included in this kit provides secure fixing and alignment during installation. Position the flashing kit around the roof penetration, ensuring the slate-grade material sits flush against the slate roof surface. Use the BDX bracket to secure the flashing in place, maintaining proper alignment and preventing movement during weathering. The bracket ensures the flashing remains in its correct position, critical for maintaining the watertight seal. Ensure all fixing points are secure before proceeding with final sealing and slate replacement around the penetration.
- Position flashing kit around the roof penetration before fixing
- Use BDX bracket to secure and align the flashing components
- Ensure flush contact between flashing and slate surface
- Check all fixing points are secure and properly tightened
- Complete final sealing before replacing surrounding slates
Material properties and maintenance
The slate-grade material construction of this flashing kit is engineered to match the durability and weather resistance of slate roofing. At 4mm thickness, the material provides robust protection against water penetration whilst remaining compatible with slate roof systems. The kit requires minimal maintenance over its lifespan due to the durability of slate-grade materials. Periodically inspect the flashing seal, particularly after severe weather, to ensure the watertight seal remains intact. No specialist cleaning or treatment is required under normal circumstances.

Limitations and important considerations
This flashing kit is specifically designed for slate roof installations and should not be used on other roof types such as tile, asphalt, or metal roofing without verification of compatibility. The 2000mm length is suitable for standard roof applications; larger or non-standard penetrations may require additional flashing components or custom solutions. Installation should be carried out by experienced roofers familiar with slate roof work and VELUX flashing systems. Proper installation is essential to achieve the watertight seal; poor installation may result in water ingress and damage to the building structure.
