Flat roofs can be installed in residential homes but it is more commonly used in commercial building. 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. 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. 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 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. It is important that you check their references before signing the contract. It might not be easy to find a competent flat roof installer on a residence. Even those who are experts in installing asphalt shingle roofing may not know how to install a flat rubber roof properly. 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. Others, however, prefer newer materials like PVC membrane or self adhering membrane system 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.
There are options for repairing a single ply membrane flat roof. You can use a black rubber glue or a peel and stick flashing material with a rubber primer that covers the seams of the membrane which is where the leaks occurs.
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.
