Flat rooms are more commonly used in commercial buildings, but you will see that there are some residential homes that have flat roofs installed on them. A flat roof that needs repair before it reaches its minimum life expectancy of the material only show that it was not properly installed; perhaps it was installed by a contractor who does not really have experience in installing flat roofs.
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. The material used for flat roofs before was not single ply rubber membrane but it was made up of a base sheet and multiple layers of felt paper and hot asphalt or coal tar. With the use of a gravel cover, the flat roofing materials increased its life. This type of flat roofing is called 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.
If you want to replace your flat roof instead of repairing it because of expense, then you should hire a roofing contractor that has experience in installing flat roofs. You need to know that they actually know how to install flat roofs and you can determine this by checking out their references, and then you can sign the contract. It might not be easy to find a competent flat roof installer on a residence. Knowing how to install asphalt shingle roofs does not qualify one to know how to install flat residential roofs.
