I am due to start a new extension for a friend of mine in the next couple of months and just want to find out the best way to finish the roof. It is a bungalow with a pitched roof. The extension is to go on the side and is to have a felted flat roof. The new extension height needs to go above existing gutter height to get required ceiling height so question is, what is the best way to join the flat roof to the existing pitched roof. I thought of removing tiles to required height and putting felt so far up underneath then replacing the tiles on completion. Maybe wrong but hope you can help me here
