Dallas Roofing: Article About Roofing Material
There are many different roofing materials that homeowners can choose among. However, a Dallas roofing contractor may recommend one material over another based on factors such as the home's location and the slope, or pitch, of the roof.
For example, on a home with an 11-degree slope, contractors may recommend that the homeowner not use asphalt shingles. On the other hand, some manufacturers and contractors say that asphalt shingles can be used in this circumstance. The NRCA, however, is not in favor of using shingles on roofs that have a slope that is lower than 18 degrees, or 4:12. Asphalt shingles are able to shed water in part because gravity pulls the water off the roof before it has time to penetrate the roofing material. On a lower slope roof, gravity does not have as pronounced of an effect.
There are different roofing options that are available for flat roofs or roofs with a low slope. These include the built-up roof, or BUR option, the modified bitumen option, PVC and single ply EPDM. Each option has its pros and cons. For example, BUR roofs are inexpensive, aesthetically pleasing and serve as a great insulator.

The downside of these roofs is that they are extremely heavy and require extensive reinforcement that often increases construction time and construction costs. Additionally, this style of roof cannot to be installed while occupants are inside the building. If there is a delay in construction, therefore, it means that the homeowner has to be outside their home for a longer period of time.
PVC roofs are easy to install and are not water permeable. This means that they can stand up to ponding. The problem with this type of roof, however, is that its seams may be vulnerable to cracking and leaks. Additionally, it does not have a long lifespan, usually only lasting from between 10 to 15 years.
Homeowners should remember that, even if they are using the best materials, if they are improperly installed on a low-sloped roof, damage will occur. Attention to detail and proper installation methods are just as important as choosing the right material. Low slope roofs require constant maintenance in order to guarantee their integrity and service life.
Most low slope roofing material manufacturers do not warranty their products when used in residential settings. The only protection that a homeowner will have is the warranty they get from their contractor. It is imperative that a homeowner works with a contractor who is detailed, thorough and professional.
