Velux advice (low pitch roof)

Samuel Shepherd

Help !

We’ve had multiple quotes for a Velux roof window or alternative. Our roof has a pitch of 10 degrees. Some of the people who have quoted the work, who are Velux installers have not recognised the roof pitch and willing to fit a window. Only two installers noted that the pitch was too low and needs to be raised with a flashing kit.

What should we do ? How important is the pitch ? And what are the options available to allow us to install a window in a 10 degree roof.

Thanks

Sam

    Hi Sam,


    It is important for a roof window to be installed within the pitches set out by the manufacturer. this is due to the systems ability to successfully drain any water that enters the system.

    The guidance to install at a higher pitch is sound however there is a product which can accommodate the 10 degree pitch you require. See link.


    I hope this helps.

    Take it from me the pitch is very important.


    When we moved into our house, the previous people had put standard Velux windows in the kitchen extension which had a very shallow pitch roof, which resulted in constant leaking and water ingress, simply because the windows rely on the pitch to drain the water away.


    In the end, when we had the roof re-roofed we had to have upstands installed which put the windows at the correct angle.
