Although there are a lot of roofers in the Dallas area, choosing a commercial roofing system can be tricky at best. If you want to aim for durability, you’ll definitely have to weigh in how the local climate might have a long term effect on your roof, and the humid subtropical climate of most of Texas (including Dallas) could make your choice pretty difficult.
The main showdown is between EPDM and metal. Although EPDM is generally considered to be the most durable flat roof among membrane roofing systems, metal is often rated at anything from 50 to 75 years. However, even though this is true in most places, the humid Dallas climate tends to even the playing field. Dallas experts consider pretty much both roofs to be on the same level when it comes to durability because of this fact. The main difference will be the use of advanced coating products that could cause one of the roofs or the other to gain an edge.
Aside from EPDM and metal roofing, TPO roofing systems are also rated quite high because of their reflective capabilities.
