Advice regarding pitched roof n top of old felt one

Anonymous user 09/03/2024 - 3.20 PM

We have recently discovered our garage roof pitch is sitting directly on top of the old flat felt roof (we were looking to have the garage insulated so we can use as a gym and keep storage as it’s currently jut brick and freezing). We have cut a hole through the flat roof and the timbers etc all look sound. We have been told we can remove the pitched roof, take out the felt one and re-install the pitch. I don’t believe it can be that easy. The roof is on a slight incline and the timbers have been cut to suit. The pitch actually does look fine so I can only assume they didn’t want to go through the hassle of removing the old one. The builder who did it is no longer active but has built many houses and extensions. We would like to have the works done properly, do i need to consult a builder or a roofer in the first instance to assess? Am i safer sticking to contractors who are members of FMB? I am googling and believe i also would need building Regs? Do I need planning permission? We’ve been in the house 7 years and it was done prior to us moving in so I don’t know how long it’s been on. HELP? Where do i start...?
