GreenGables Posted July 25, 2023 Share Posted July 25, 2023 Hi, My architect specified a flat roof slope of 1:80 minimum with firings. In reality there is little to no fall (measured with electronic level) and a lot of water is pooling on the GRP roof for days on end. Should I accept this? Water is even pooling near the drainage outlet as there is insufficient slope. Advice appreciated. GG Link to comment Share on other sites More sharing options...
nod Posted July 25, 2023 Share Posted July 25, 2023 It’s normal The big commercial roofs have water everywhere an rely on the wind and sun to dry these up Link to comment Share on other sites More sharing options...

Conor Posted July 25, 2023 Share Posted July 25, 2023 They use the same stuff for swimming pools and ponds. The issue will be a bit more maintenance for you as crud is more likely to accumulate. Link to comment Share on other sites More sharing options...
