If your business has a commercial flat roof, you need to know that it will stand the test of time to protect your business. But navigating the world of commercial flat roofs can be a bit tricky if you are new to it. You may have heard the terms TPO and EPDM and wonder how these two commercial flat roof systems stack up.


At A-Plus Roofing serving the Twin Cities, we offer commercial roofing expertise in a wide range of roofing systems and can help you navigate the challenges of installing and maintaining your roof. We’ve put together this guide to help you understand how TPO and EPDM measure up when compared.


TPO Commercial Roof Membranes

TPO stands for Thermoplastic Polyolefin. It is a single-ply roofing membrane with reflective properties. TPO is made from polypropylene and ethylene-propylene rubber which is polymerized together. TPO is resistant to damage from the sun’s ultraviolet rays as well as chemicals.


Advantages of TPO Membranes

TPO offers many advantages as a commercial flat roofing system. It offers excellent protection from all kinds of weather, which means it can easily hold up to Minnesota’s harsh winters. Thermoplastic roofs also help reduce heating and cooling costs. TPO is also able to meet and exceed recommended fire protection standards.


TPO roofs are resistant to the following:

●        Dirt

●        Oils

●        Bacteria

●        Salts

●        Algae

●        Debris buildup


EPDM Rubber Roofing

EPDM stands for ethylene propylene diene monomer. It is a type of synthetic rubber membrane and an elastomer known for its many possible applications. It is often used as a roofing membrane because of its environmental properties. Much like TPO, it provides an excellent barrier to extreme weather conditions, including hail. Additionally, it also resists UV rays and helps minimize heating and cooling costs. It also offers excellent resistance to both acidic and alkaline substances.


Additional EPDM Membrane Advantages

Just like TPO, EPDM offers a high degree of fire resistance. In fact, because EPDM roofs are virtually impossible to ignite, they may dramatically impede the progress of a fire. EPDM roofs can last as long as 50 years or more, making them an environmentally friendly choice. They are also completely recyclable.
