When it comes to commercial roofing materials on the market, thermoplastic olefin (TPO) is growing in popularity, and for good reason. A rubber material that has been around for more than 20 years, TPO roofing features a three-layer membrane that offers some significant advantages over other commercial options available today. Below are some of TPO roofing’s distinct benefits:

There are two types of sheet membranes for commercial roofing systems:e thermoplastic (can be remelted) and thermoset (remains in a permanent solid state). One of the most popular thermoset roofing materials today is ethylene propylene diene terpolymer, or EPDM. A durable synthetic rubber membrane used in flat roofs, it contains oil and natural gas ingredients that help enhance its performance. To install these membranes, installers seal the seams using specially formulated tape or liquid adhesives.

Modified bitumen roofs are made of polymer modified bitumen membranes applied using heat to secure the seams between runs of roofing material, giving the system its strong and durable protective layer. And due to their low-maintenance requirements, modified bitumen roofs are among the most installed materials in commercial roofing today.
