TPO vs EPDM: Compare Your Roofing Options

By : Guillermo Molina Matus

If you are a homeowner planning to install or replace your roof, you must have come across several roofing options. Two of the most popular options include TPO (Thermoplastic Olefin) and EPDM (ethylene propylene diene monomer). However, choosing between the two might be particularly challenging, especially if you do not know how to differentiate them. As a professional roofing contractor, G and Bros Roofing Salisbury MD, we have worked with various roofing materials and have all your answers. This blog post will highlight the differences between TPO and EPDM to help you make an informed decision.


TPO is a type of single-ply roofing membrane that has become increasingly popular in recent years. It is a synthetic material made of rubber, plastic, and reinforcing filler elements. TPO roofing is known for its durability and flexibility, which makes it ideal for areas with extreme temperature fluctuations. It is also resistant to UV radiation, making it an excellent option for sunny parts of the country.

Some of TPOs advantages include:
  • Energy efficiency, which means it can help lower energy bills.
  • Easy to install and repair.
  • Durability, often lasting up to 25 years.
  • Environmentally friendly.


EPDM is also a single-ply roofing membrane made from synthetic rubber. It has been around for over 50 years since its discovery, making it a popular roofing choice. EPDM is known for its low cost and reliable performance. It is also resistant to punctures, tears, and impacts that would otherwise damage other roofing materials.

Some of EPDMs advantages include:
  • Long lifespan, typically lasting between 20 and 30 years.
  • Cost-effective, making them ideal for low budgets.
  • Easy to install and repair.
  • Resistant to UV radiation.


When it comes to choosing between TPO and EPDM, several factors must be considered. These factors include resistance, installation, weather, and climate, maintenance, cost, and lifespan. For example, if you prioritize durability, energy efficiency, and flexibility, TPO might be the right option. In contrast, if you are looking for a low-cost, reliable, and low-maintenance roofing system, EPDM would be the perfect match.
