JoshB Posted June 19 Share Posted June 19 Hi, Ive just had a rubber flat roof fitted. No issues with my old flat, it had just been down 20+ years. It’s been down around 3 weeks. We had pretty heavy rain on Friday and there is still a puddle in the centre of the roof today. (Wednesday) is this an issue? Looking up there it looks like it will struggle to drain either side and will only go if it evaporates. Link to comment Share on other sites More sharing options...
Kelvin Posted June 19 Share Posted June 19 (edited) Pooling water isn’t ideal and on the long list of reasons why flat roofs fail that’s one of them. I assume the roof has a fall but is sagging at this point. What’s the underbuild? Did the roofers install this or was the new membrane installed over the existing underbuild? Can you easily get to it from the inside? How does it interface with the upstand at the pitched roof? Edited June 19 by Kelvin Link to comment Share on other sites More sharing options...

They said on quote that everything would be stripped. We had an old felt one before. Didn’t go cheap by any means, was a 3 grand job. Link to comment Share on other sites More sharing options...

steveoelliott Posted June 20 Share Posted June 20 (edited) I know your pain, happened to me when my membrane was replaced and the roofer just replaced membrane without checking falls etc. I was told that it's not a problem per se but I do have a minor leak now it seems so I will look to replace again and get the job properly.

SteamyTea Posted June 20 Share Posted June 20 We'll come winter it won't leak until the thaw comes. Water is called 'the universal solvent' for a reason. Link to comment Share on other sites More sharing options...

Sadly this is commonplace and the combination of flat roof and parapet wall is particularly prone to failure. Link to comment Share on other sites More sharing options...
