Low Pitch Roof Window System
The solution for roof windows as low as 10º.
At Forticrete we recognise that often homeowners will want a lower pitch roof to enable them to extend their property as far as they can so we have invested significant research and development into designing a roof window system which can be installed into a lower pitch roof.
Conventional roof windows and flashing kits work by discharging water up and over the face of the tiles. At lower pitches water does not run off so quickly and can therefore pool and lead to water ingress. The Forticrete Low Pitch Roof Window System solves this using a patented two-piece tray drainage flow system, which collects any water which runs under the tiles and disperses it across the trays, over the fascia and into the gutter in a controlled manner.
