  • Glass rooflights on a flat roof should be a fitted to a minimum pitch of 3° to aid runoff and to stop water pooling on the unit.  Although the minimum pitch is 3° you may wish to consider a pitch of around 5° to ensure adequate runoff on larger skylights. The pitch of the unit rooflight is something that will affect your warranty so it is important to get this detail right when installing a new glass rooflight.  The minimum and maximum pitch required for rooflights differs between brands so please check individual products for more information.
