Finding Parallels Between Services and Life
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. This flat roof is called the 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. There are flat roof installers around who would prefer to work on commercial flat roof installations rather than residential roof installation, but it is still not impossible to find a good flat roofer for residential applications.
If you are installing flat roofing, you can use one of several 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. Choose a roofing contractor in your area with plenty of experience. Location of your house is important since there are materials that wok best in extreme hot or cold
If you have a single ply membrane flat roof and you think that it can still be repaired then you have some options for repairing it. 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.
Your flat roof’s life can be extended for a limited period with this repair. These repair materials don’t usually come in small quantities so unless you can find a roofing contractor who will sell you just the amount you need, you may end up spending a lot of money on materials.
