VELUX Standard Flashings 55x78cm EDP CK02 0000

Is this the right flashing for your roof window?

This Standard Flashing is specifically designed for VELUX CK02 roof windows only. Before purchasing, confirm your window size matches CK02. Check your roof pitch does not exceed 55°, as this flashing is not suitable for steeper pitches. The flashing dimensions are 55×78cm and are matched to the CK02 window frame size, so compatibility is determined by your window model rather than roof dimensions.

  • Confirm your VELUX roof window is size CK02
  • Measure or verify your roof pitch is 55° or less
  • Check that you are replacing or installing a standard flashing type, not a combination or special flashing variant

What is included and material

This product is a single Standard Flashing unit manufactured from durable aluminium. The aluminium construction provides excellent weather resistance and requires minimal maintenance over its lifespan. The flashing dimensions of 55×78cm are fixed and matched to the CK02 window opening.

  • One aluminium Standard Flashing per pack
  • Dimensions: 55×78cm
  • Durable aluminium material for long-term weather protection

Pre-installation checks and preparation

Before fitting, inspect the flashing for any damage during delivery. Ensure your roof structure is ready to receive the window and flashing. The flashing must be carefully aligned with your roof tiles or slates to guarantee proper water run-off away from the window frame. Poor alignment can compromise the weathertight seal and lead to water ingress. Have your roof opening prepared to the correct dimensions for a CK02 window, and ensure the surrounding roof surface is clean and ready for integration.

  • Check flashing for transport damage before installation
  • Prepare roof opening to CK02 specifications
  • Clean roof surface around the opening
  • Plan tile or slate alignment to ensure water runs away from the window frame

Installation and performance

Installation of this flashing requires precision to achieve the weathertight seal it is designed to provide. The flashing integrates the window frame with your roof structure, so alignment with your roof tiles or slates is critical. Improper installation may result in water ingress at the roof junction. If you are not experienced with roof window installation, consider engaging a qualified installer to ensure the flashing performs correctly and your roof remains weathertight.

  • Align flashing carefully with roof tiles or slates
  • Ensure proper water run-off gradient away from window
  • Follow VELUX installation instructions precisely
  • Consider professional installation for best results
