Suitable applications and roof types
This flashing system is engineered specifically for slate roof installations. It is suitable for both new build projects where roof windows are being incorporated into the original design, and refurbishment work where windows are being retrofitted into existing slate roofs. The 78×140cm size accommodates standard VELUX roof window and Sun Tunnel system openings. Always verify that your VELUX window model is compatible with this MK08 flashing specification before ordering.

Installation and weather-tightness
The Pro+ specification includes all installation products needed for a complete, professional installation. The flashing system is engineered to create a weather-tight seal around the window opening, managing water run-off and preventing ingress into the roof structure. Proper installation is critical to ensure long-term performance; follow VELUX installation guidance carefully and ensure the flashing sits correctly against the slate roof surface. The system maintains visual consistency with slate coverings, providing a neat finish that integrates with the existing roof.

On-site handling and maintenance
Store the flashing kit in a dry location on site before installation to prevent damage to components. During installation, handle the flashing carefully to avoid denting or distorting the profile, which could compromise the weather-tight seal. Once installed, the flashing requires minimal maintenance; however, inspect the seal periodically, particularly after severe weather, to ensure it remains intact and free from debris. Keep the area around the flashing clear of moss, lichen, and leaf litter to maintain proper water drainage.
