This type of roofing comes in a few varieties. Most of the time, EPDM is used. This low-cost rubber roofing can be used on any kind of material, and it is fairly durable. For a more expensive and more durable roofing option, you could go with a single ply PVC or TPO roof.
PVC is a pretty common choice due to how easy it is to manufacture and install. It’s also very durable, but it can cost more than some of the other methods. Still, it is widely used across the US and Europe for commercial roofing.
TPO has a higher installation cost, but the materials are fairly inexpensive. Solvents are required when installing, causing the installation process to take longer than similar roofing methods. However, TPO is incredibly durable and very weather resistant. This is one of the best roofing solutions for areas that experience a lot of inclement weather. It also has the longest life expectancy and is considered to be the most environmentally friendly of all the singly ply roofing options.
EPDM is the most flexible of the three options, and that means it will work best for industrial structures where internal temperatures can change dramatically throughout the day. As the temperature changes, the roofing materials will stretch and shrink, and EPDM can handle all of that very well and still manage to hold up.
Any one of these roofing options can last as much as 20 years, but in some cases, you can expect your roof to last 30 or 40 years. How long it lasts depends partly on the installation process and the kind of materials used. EPDM tends to last the longest on average, but the environmental factors that affect the roof can determine the lifespan of the roof as well.
