The pitch of your roof will dictate which roof window flashing you requite, and is important to understand, so you purchase and install the correct roof window.
To help, FAKRO have developed a clever mobile friendly roof pitch calculator, which you can access from any mobile device.
If you are at all unsure, you should seek the advice of a roofer or your architect. Alternatively you can contact FAKRO Technical Support on 01283 554755.
