What is the minimum drainage falls for a single ply flat roof?
The recommended minimum fall for a flat roof is 1:80 (0.72⁰). This applies whether the waterproofing is a polymeric single ply membrane, a reinforced bitumen membrane, or another type listed in BS 6229:2018, the code of practice for flat roofs with continuously supported flexible waterproof coverings. To achieve a 1:80 fall, the code of practice […]
