Although flat roofs are more common in commercial buildings, you will also see some residential homes with flat roof installation. Somehow, most of these residential flat roofs were installed by contractors with little or no experience dealing with flat roofs so that they need repairs before reaching the minimum life expectancy of the material.
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. With the use of a gravel cover, the flat roofing materials increased its life. What this is commonly called is built up roofing. When used in residential applications, this type of roofing which uses less high tech material outlast the single ply rubber membrane. Because of inconsistency in installation procedures, this will be true.
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. 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 can be difficult to find a competent roofer that knows how to install flat roofing on a residence. Even those who are experts in installing asphalt shingle roofing may not know how to install a flat rubber roof properly. Flat room installers usually only do commercial roof installation, but if you really take your time looking for a good one, you can surely find one.
There are many materials used in new flat roof installations today. One material used is the single ply membrane which is used for commercial roofing with a low slope. PVC membrane or self adhering membrane system are some of the newer materials used and these use hot air welded seams. Whatever materials the roofing contractor prefers, he will use it. A roofing contractor with many years of experience is the ideal contractor to hire. There are materials that work best in extreme heat or cold and this means that your location can make a difference.
