When it’s time to replace your flat roof, knowing which type of material to use can be difficult. While each type presents its own benefits, it presents its own drawbacks as well. 

Having an idea of the basic features and setbacks of the popular flat roofing types can help you make an educated, knowledgeable decision of the type of roof that’s best for your building.


Otherwise known as rubber roofs, this material is extremely durable and can last more than 50 years. With little to no seams, EPDM roofing is less likely to leak than other materials. These roofs are also incredibly resistant to UV rays which makes them one of the most energy-efficient choices available. However, these roofs should always be installed by an experienced professional to prevent shrinking around vents and other protrusions. These roofs can also be punctured easier than other types of roofing. However, EPDM roof repairs are quick and simple for a professional.


While this is one of the more costly flat roofing options, PVC roofs have extensive benefits. They can last more than 50 years and are sealed by heat-welding so they have very few leaks or separations. The white color and reflective materials give PVC phenomenal resistance to UV rays and can substantially lower your energy costs. They are extremely flexible and can withstand weather, debris, and animal damage as well as bacteria, mold, and mildew. However, these roofs are more difficult to repair when needed, and will require more equipment and service time than an EPDM roof.


As another, a less expensive option for heat-welded seals, TPO flat roofing definitely has its advantages. These roofs are very durable and can resist tears, weather, and water. It’s also highly energy efficient because of its white color and reflective polymers. This system is very flexible and is a great choice for buildings that expand and contract heavily. However, TPO roofing is fairly new and professionals are not sure about the long-term resistance factors. There have also been cases where extreme heat can cause premature deterioration of the material.
