Repairs vary depending on what you consider a "flat" roof. A level roof, with no pitch, is best protected by a membrane covering. The material is a plastic or vinyl product and comes in rolls. Cut to proper length, allowing for a flash up walls, and "butt" the joints which are then heat "welded" together to form a single continuous membrane. Roof that have a small or slight pitch for runoff can be protected with a felt "roll roofing", overlapped seams and an asphaltic mastic under the entire surface.
