Flat roofs give certain homes a unique appearance and appeal. When looking to install a flat roof, there are several different types available to choose. Each type of roof is made from different materials and has certain advantages and disadvantages that may make them more suitable for some home but not others. A Fort Worth roofing expert can assist those who are deciding what type of flat roof they would like to have installed.
Built up roofs are comprised of layers of waterproofing materials and hot tar. Most of these roofs have fiberglass membranes that make them more durable. Built up roofs have a number of advantages, including low cost. Once this roof is installed it, it needs very little maintenance beyond removing organic debris and checking for leaks. Unlike some of the other types of flat roofs, built up roofs can be extremely heavy. It can also be difficult to install for those who do not have the roofing experience; as such, this material should be installed by a professional.
Modified bitumen roofs are made from single ply rolled materials that have been impregnated with minerals. There are two main types of modified bitumen roofs: torch down systems and peel and stick systems. Torch down systems require heat from a blowtorch to activate the adhesive.

Peel and stick systems are often easier to install as the backing just has to be removed. This material is reflective, meaning that sunlight is not absorbed. This can reduce energy bills during the summer. The major downside to modified bitumen roofs is that they are not resistant to scuffing or tearing.
Rubber membrane roofs, known as EPDM roofs, are made from a durable rubber material. This rubber was designed to resist damage that can be caused by extreme sunlight. The installation of this material is quick and easy. If the material does tear, a professional can patch the material to extend the roof's lifespan. Light colored rubber membranes can be much more expensive than the darker colors, though they reflect more sunlight.
Most flat roofs are rated to last between 10 and 20 years depending on the materials and the climate, though some roofs can last as long as 25 years. Some like to install these roofs themselves, though this is not recommended as a poorly installed roof will fail relatively quickly, costing the homeowner in expensive repairs. Ultimately, when flat roofs are installed on the right home, it can be a financially sound decision.
