What is the Purpose of Roof Window Flashings?

Roof Window Flashings are seals that sit between the roof window and the roofing material. The flashing is a thin, continuous strip of material, and can be made using plastic or metal.

They’re an incredibly important part of the window, as they create a watertight closure around the edge of the window, preventing rainwater from entering the building through the window edges.

In this handy article, we’ll go over what exactly Roof Window Flashings do, and how the different types of Roof Window Flashings are categorised.  

What do Roof Window Flashings do?

The main purpose of Roof Window Flashings is to ensure that the seal around the window is completely watertight. This stops rainwater from getting into the house and causing water damage, which unfortunately is hard to spot until it’s too late.

The seal created by Roof Window Flashings also protects from other weather factors, such as wind or cold air, which otherwise may infiltrate the property through the window edges and make the house cold!

Which type of Flashing should I use with my window?

Roof Window Flashings are categorised based on a few different factors:

• Roofing material – roofs can feature a wide variety of materials, and the flashings need to work alongside this. Flashings for different materials include those for flat, plain tiles, those for roof tiles that have a curved, overlapping profile, and those for slate tiles, which are thin and flat
• Window height – because the flashing creates a seal between the window and the roof, there are different types of flashing depending on how flush the window is desired to sit against the roof
• Roof pitch – this refers to the angle of the roof. Most flashings will fit all roof pitches, but there are some that are produced specifically for steeper pitched roofs

We supply a wide range of Roof Window Flashings for any type of roof window, including standard flashings as well as special flashings for additional thermal protection.
