I live in a very old thatched cottage which has a single story extension on the back. It has a flat roof which is coming to the end of its useful life so I am considering doing away with the flat roof and building on a pitched roof with a covering of slates. Are there any regulations I should be aware of? the pitch will be quite shallow which is why I thought slates would give the quickest run off?
Any advise gratefully recieved. Thank you.
