Roof Windows for Flat Roofs

So what roof covering do you have? Mastic asphalt, bituminous membranes (roll and pour, torch-on), single-ply rubber/EPDMs, GRP, liquid solutions etc. These would be the material for a traditional flat roof in the UK. Roof windows for these types of construction are normally glass or polycarbonate and would certainly be fitted out-of-plane. They may also be profiled such as a dome, barrel vault, pyramid, ridge light or just flat. The roof window would also require a manufacturer's upstand or builder's kerb, which has to be waterproofed using the materials above. Ventilation can be included within the roof window. This could be a hinged option using a manual or electrical type of opener or it could also be permanent or controllable ventilation within the upstand (hit and miss or trickle vents). There are sliding opening options available as well as access roof windows and automatic smoke ventilators too.
