Fixing and buying guide

What this product is and who needs it

A recessed tile flashing is a metal or composite component that integrates a roof window into a pitched tile roof whilst maintaining a neat, flush finish with the surrounding tiles. This flashing is specifically designed for the VELUX CK06 window size and is essential if you are installing a new VELUX roof window or replacing an existing one on a tiled pitched roof. It prevents water ingress and weather damage by directing rainfall away from the window frame and into the roof drainage system.

Compatibility and sizing

This flashing is engineered exclusively for VELUX CK06 roof windows and measures 550×1180mm with a 90mm flashing depth. Before ordering, confirm that your roof window is a CK06 size and that your roof is a pitched tile construction. The flashing is not suitable for flat roofs, metal roofing, or other window manufacturers' products. Check your existing window documentation or measure the frame dimensions to verify compatibility.

• Window size: CK06 only
• Flashing dimensions: 550×1180mm
• Flashing depth: 90mm
• Roof type: Pitched tile roofs only
• Not compatible with other VELUX window sizes or roof types

What is included and pre-installation checks

The flashing unit arrives with all necessary installation materials included, so you should not need to source additional fixings or sealing products separately. Before installation, inspect the flashing for any transport damage and ensure your roof structure is sound. Check that the roof opening is correctly sized for the CK06 window and that the surrounding tiles are in good condition. Clear any debris from the roof opening and ensure the area is dry before beginning work.

Installation and professional fitting

This flashing should be installed by a competent roofer or experienced installer familiar with VELUX roof window systems. The recessed design requires careful positioning to ensure the flashing sits flush with the tile plane and that all seals are properly compressed. The included installation materials support on-site fitting, but correct technique is critical to achieve a weather-tight seal. Poor installation can lead to water ingress and structural damage, so if you are unsure, engage a qualified roofer to carry out the work.
