VELUX Slate Flashings 94 x 118cm EDL PK06 0000
Suitable applications and roof types
This slate flashing is designed exclusively for use with VELUX PK06 roof window systems on slate-covered roofs. It is suitable for both new build installations and refurbishment work where existing slate roofs are being upgraded with roof windows. The flashing creates a weather-tight transition between the roof window frame and the slate tiles, preventing water ingress at this critical junction. It is not suitable for use with other roof window systems or on non-slate roof coverings such as tiles, felt, or metal roofing.
- Use only with compatible VELUX PK06 roof window systems
- Suitable for slate roof installations in new build and refurbishment projects
- Creates weather-tight seal at the roof window perimeter
- Maintains visual consistency with existing slate roof finish
Installation and positioning
The flashing must be installed as part of the complete PK06 roof window assembly. The 940 x 1180mm dimensions are engineered to fit the specific frame size of PK06 systems. Installation should follow VELUX's detailed technical guidance to ensure the flashing sits correctly beneath the upper slate courses and overlaps the lower courses appropriately. Correct positioning is critical for weather-tightness; the flashing must be fully bedded and sealed according to manufacturer instructions. Professional installation is recommended to guarantee a weather-tight finish and maintain warranty compliance.
- Install as part of the complete PK06 roof window system
- Position flashing to overlap slate courses correctly
- Ensure full bedding and sealing per VELUX instructions
- Follow manufacturer guidance for weather-tight performance
Weather protection and maintenance
Once installed, the slate flashing provides a durable, weather-tight seal designed to perform reliably in typical UK roof conditions including rain, wind, and temperature fluctuations. The flashing itself requires minimal maintenance; however, you should periodically inspect the seal around the roof window perimeter, particularly after severe weather, to ensure no debris has accumulated or damaged the weatherproofing. Keep the flashing and surrounding slate tiles clear of moss, lichen, and leaf debris that could trap moisture. Any gaps or deterioration in sealant should be addressed promptly to maintain weather-tightness.
