Roof hatch – built-up roof

Aluminium-framed roof hatches – made by companies like Bilco – provide roof access for maintenance teams and may also be used to provide natural smoke and heat exhaust ventilation (NSHEV) for commercial and public buildings.

Weatherproofing roof hatches One of the many benefits of an aluminium-framed roof hatch is that it includes its own upstand – so there’s one less element to worry about during installation. Once the roof hatch is installed, with suitable supports and trims, it’s time to weatherproof. The Jones and Woolman UK in-situ weathering solution is perfect for these installations due to its quick and straightforward application. The fibre-reinforced, cold-applied liquid can be applied on any surface and once it’s dry, it provides long-term protection from rain and wind, as well as long-term durability. Below, you can download a technical drawing that shows all the different parts of a commercial roof hatch installation on a built-up roof.
