Flat roofs can be installed in residential homes but it is more commonly used in commercial building. It is difficult for the inexperienced to install a flat roof, and what happens when this is the case is that the flat roof will need repair even before it reaches its minimum life expectancy.
If one uses a single ply rubber membrane in a flat roof, and if it was not properly installed, then the roofs will leak easily. Before, flat roofing did not use this material but it was made of a base sheet and multiple layers of felt paper and hot asphalt or coal tar. Gravel was used to cover the roof in order to increase its life. What this is commonly called is built up roofing. When used residentially, the built up roofing outlasts the roof that uses single ply rubber membrane despite using less high tech materials. Because of inconsistency in installation procedures, this will be true.
