The front section of our garage roof is the one remaining flat roof on the house and is starting to bubble so I'm thinking of replacing it with a pitched roof.
The current shape is a trapezium and so I'm concerned as to how to cope with the side which creates the narrowing. Do I follow the current shape and have to cut tiles to follow the narrowing, or do I create an overhang to 'lengthen' the narrow end and make the roof rectangular?
Or something else?
