Single-ply membrane roofs are commonly used in commercial buildings. Among several single-ply options, two of the most popular are TPO (Thermoplastic Polyolefin) and EPDM (Ethylene Propylene Diene Monomer).
Carney Roofing Company, one of the most reputable local roofing contractors, compares TPO and EPDM based on these factors:
Installation
TPO is installed with the use of hot air welding, which can be a complicated process. Because of this, it’s very important to hire a professional with specialized skills and knowledge for this job. EPDM, on the other hand, does not require special equipment, so it’s ideal for those who want a faster installation process.
Maintenance
EPDM is generally easier to maintain than TPO. In terms of roof repair, a special process is often required in order to weld new material onto an old TPO membrane. Meanwhile, for EPDM, it’s important to pay close attention to the seams. These are typically treated with adhesive, so they may come apart and require repairs over time.
Durability
When it comes to durability, your roof maintenance company can surely vouch for both of these single-ply options. Since EPDM is made from rubber compound, it can offer great resistance to ozone, UV light, and harsh weather conditions. Meanwhile, TPO has a seam strength that’s three to four times better than the adhesive and tape seams of EPDM.
Energy Efficiency
TPO is usually designed with cool roofing technology, and some TPO products may also come with sun-reflective properties. These can help TPO maintain a cool thermal balance inside the building, making it an energy-efficient option. EPDM also has reflective properties, but it’s not capable of offering the same amount of savings as TPO.
