Roof Window Flashing Kits

Flashing kits are essential for directing rainwater safely away from the roof window and preventing water ingress. They are selected based on roof pitch and roofing material, such as tile or slate, and are available in standard, recessed and high-profile options to suit different roof designs.

Our flashing kits are suitable for use with a wide range of pitched roof windows, helping ensure a clean finish and reliable weather protection.
