Pre-installation checks

Before beginning work, inspect your roof opening and surrounding tiles. Ensure the opening dimensions and roof pitch are compatible with a VELUX MK08 window. Verify that all plain tiles around the opening are in good condition and do not exceed 14mm thickness. Check that you have the correct VELUX roof window or Sun Tunnel unit ready for installation. Confirm that the flashing kit is undamaged and all components (BDX and BFX products) are present. Have appropriate roofing tools, sealants, and safety equipment ready before starting installation.

• Confirm roof opening dimensions suit VELUX MK08 window
• Check all plain tiles are sound and under 14mm thick
• Verify VELUX window or Sun Tunnel unit is compatible and on site
• Inspect flashing and all included components for damage
• Gather roofing tools, sealants, and safety equipment in advance
