Although flat roofs are more common in commercial buildings, you will also see some residential homes with flat roof installation. 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 a flat roof is installed with a single ply rubber membrane, it usually leaks easily and will require repairs. This type of material is not what was used before where the flat roofing was made up of a base sheet and multiple layers of felt paper and hot asphalt or coal tar. In order to increase its life, it was covered with gravel. 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. And the reason for this is because of the inconsistency in installation procedures.
So instead of repairing your flat roof which is really expensive, you decide to replace it with a new one, make sure that the roofing contractor that you will hire has years of experience in installing flat roofs. Before signing a contract make sure you check referrals. If you are looking for a flat roof installer for residential homes, you might have to look long and hard to find one.
