Hi guys
A bit of a problem with my fibreglass flat roof. Asked the roofer to keep slope at least 2 deg. He built it at 1 deg! See the pool of water in attached photo? its now a bit bigger. To make things worse the plasterer brought the sand cement plaster finish on the vertical all the way down (covering the upstand with it) to the roof and drove a nail close to the water so the roof leaks at this point. What are my options?
Thanks in advance.
