Whose job is it to check a flat roof has the right slope

Anonymous user 09/03/2024 - 2.37 PM

Hi, we have just had our builder leave our job due to a few problems. Before they left they put in a flat roof dormer window(the builders chippy put in the timber frame), with a local roofing company doing the roof, lead and making good. Now I've gone up and checked and the roof is completely flat so water is pooling on it, I don't see any slope at all. Whose responsibility is it to check that the flat roof has the correct, sufficient slope? I would expect the roofer should check this?? I already paid the builder to pay the roofer so I'm not holding any money to make sure they come back. Is it normal for people to hold retention or what a couple of weeks to make payment, for example while a building inspector checks the work? thanks

Are you a tradesperson and able to answer this question?

It depends who installed the timber deck. If the carpenter laid the deck then he should have fitted firings to each joist to provide a fall. If the roofer was only asked to fit the waterproof covering then it is the carpenters fault but the buck should stop at the main contractor who you employed.

The roofer is to blame he should have checked the roof had a 3" fall going to the guttering before he made it waterproof and he should not have been paid until it was checked by the building inspector

answer two is more correct, (if thats possible,) but it is not necessary anyones responsibilty unless working to drawings, then it is the carpenters fault if he does not adhere to the required falls unless the degree of fall (slope) is governed by any steels (RSJ) than its the fault of the builder (Installer). But putting all that aside, water does not degrade a flat roof, the sun does and any flat roof worth its salt, should be able to hold water anyway
