VELUX flashing kits are designed to integrate your VELUX roof window perfectly into the roofing material, ensuring that your window is completely weathertight, whatever the conditions. We offer a range flashings designed for different roofing materials and provide two options for installation height. 

Use the descriptions below to pick the appropriate flashing kit for your project, or alternatively select your flashing kit using the make and model of tile or slate by using our flashing guide.

Standard or recessed installation

VELUX New Generation roof windows offer two installation heights, standard or recessed.

Recessed installations offer a more sleek, streamlined appearance, sitting 40mm deeper in the roof structure. Recessed installations also offer greater energy efficiency, and when installed with the appropriate VELUX insulation collar actually offer a lower certified u-value, saving energy and providing architects with greater design flexibility.

*Please note, the structural opening size required for your window will differ depending on which flashing kit is used, remember to consult the instruction manual supplied with your flashing prior to setting out the roof for installation.
