Fixing and buying guide

What this product is and who needs it

These flashings are purpose-designed sealing components that bridge the gap between your roof surface and the rooflight or skylight frame. They are essential for any property owner or builder installing VELUX rooflights or skylights, whether on new builds or renovation projects. Without proper flashing, water penetration around the rooflight opening will cause damage to roof structure, insulation, and interior finishes.

Compatibility and sizing

The EKL PK08 S0122 flashings are sized at 94 x 140cm and are designed specifically for VELUX rooflights and skylights in the PK08 range. Before purchasing, confirm your rooflight model matches the PK08 specification. These flashings work on both flat and pitched roof applications, with the adjustable clip system accommodating various roof pitches and construction methods. Check your roof pitch and rooflight frame dimensions against the product specifications to ensure correct fitment.

• Confirm your VELUX rooflight is PK08 size before ordering
• Suitable for pitched roofs and flat roof installations
• Adjustable clips accommodate different roof pitches
• Dimensions 94 x 140cm must match your rooflight opening

Pre-installation checks and preparation

Before fixing, inspect the rooflight frame and surrounding roof structure for damage or deterioration. Ensure the roof opening is clean and free from debris, and that the rooflight frame is level and square. Check that you have suitable fixings appropriate to your roof construction—these may differ for timber, concrete, or metal substrates. Review the manufacturer's installation guidance to confirm the correct fixing method for your specific roof type and material.

• Inspect rooflight frame and roof opening for damage
• Clean the area around the opening thoroughly
• Confirm the rooflight frame is level and square
• Identify the correct fixings for your roof construction type
• Read VELUX installation instructions before starting work

Installation and fixing

Position the flashing around the rooflight frame and use the adjustable clip system to secure it in place. The clips allow flexibility to accommodate your specific roof pitch and construction. Follow the manufacturer's guidance on fixing locations and use appropriate fasteners for your roof material. Ensure the flashing creates a continuous watertight seal with no gaps or overlaps that could allow water ingress. The BS EN 12410:2011 standard compliance confirms the flashing meets rigorous weather resistance requirements when installed correctly.
