Frost Frost large sump roof deck drain, complete with cast aluminium dome and an outlet size 4' BSP. Domed rain water outlets are suited to cold roof construction where the waterproof membrane is located on top of the roof deck.


The primary purpose of any roof drainage system is to remove water from roofs as quickly as possible in a controlled and predictable way.

Factors including roof outlet size, shape, appearance and anticipated drainage requirements need to be taken into account. Design is usually the responsibility of consulting engineers familiar with the roof construction, piping systems and additional functions intended for particular roofs.
