Flat Roof Kerb

Use the VELUX Roof Pitch app to measure the pitch of your roof to help you choose the right roof window.

The height and placing of the roof window have to be adjusted according to the pitch of the roof. "The lower the roof pitch, the longer the roof window”.

VELUX^® recommends that the top of the roof window is installed approximately 200 cm above the floor.

Download the iphone app, then place your phone directly on the roof to see the pitch or use the build-in camera mode to find the pitch directly.
