Flat roofs can be installed in residential homes but it is more commonly used in commercial building. 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.
You will experience leaking early on if your roof is installed with a single ply rubber membrane, and more so if it was not properly installed. 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 in residential applications, this type of roofing which uses less high tech material outlast the single ply rubber membrane. And it is only because the installation procedure is inconsistent.
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. Before signing a contract make sure you check referrals. 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. Most flat roof installers only take on commercial roofing jobs, but if you are patient in looking for a flat roof installer for residential applications, then youwill surely find one.
Flat roof installation can make use of different materials. 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. Roofing contractors would use materials that fits their preferences. Choose a roofing contractor in your area with plenty of experience. There are materials that work best in extreme heat or cold and this means that your location can make a difference.
There are some options to repair your single ply membrane flat roof. Seams of the single ply membrane is where the leaks occur and so to repair this means to cover the seams with black rubber flue or peel and stick flashing material.
This can extend the life of your flat roof for a short period. If you don’t want to spend a lot of money for repair materials since they don’t come in small quantities, you should find a roofing contractor who will sell you the amount that you need.
