EPDM vs. TPO Roofing: What’s the Difference?

Jake Stolzfus • January 15, 2025

Choosing the Right Flat Roofing Material for Your Building

When it comes to flat or low-slope roofing systems, EPDM and TPO are two of the most popular choices. Both are durable, energy-efficient, and cost-effective, but they have key differences that may make one more suitable for your needs than the other. At Premier Roof Solutions, we’re here to help you understand these materials so you can make an informed decision.

What Is EPDM Roofing?

EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber roofing membrane that has been a trusted choice for decades. It’s known for its:

Durability: EPDM is highly resistant to UV radiation, ozone, and extreme temperatures.

Flexibility: Its rubber-like texture allows it to adapt to structural movements, making it an excellent choice for climates with fluctuating temperatures.

Longevity: With proper maintenance, EPDM roofs can last 20-30 years or more.

Ease of Installation: EPDM membranes are lightweight and can be installed quickly using adhesives or fasteners.
Best Applications for EPDM

EPDM is ideal for buildings in areas with extreme heat or cold and for structures where cost-effectiveness and ease of installation are priorities.

What Is TPO Roofing?

TPO (Thermoplastic Polyolefin) is a newer single-ply roofing membrane that has gained popularity due to its energy-efficient and eco-friendly properties. Key features include:

Energy Efficiency: TPO’s reflective surface reduces heat absorption, lowering cooling costs and meeting ENERGY STAR® standards.

Durability: It resists punctures, tears, and microbial growth, making it suitable for various climates.

Eco-Friendliness: TPO is fully recyclable and free of harmful chemicals like chlorine.

Variety of Colors: Unlike EPDM, TPO comes in multiple colors, including white, gray, and tan, to suit different aesthetic preferences.

Best Applications for TPO

TPO is an excellent choice for energy-conscious building owners looking to reduce cooling costs or for roofs that require higher resistance to punctures and microbial growth.

Which Roofing System Is Right for You?

Choosing between EPDM and TPO depends on your specific needs:

Energy Efficiency: Opt for TPO if reducing cooling costs and environmental impact is a priority.

Cost and Flexibility: EPDM is a great option for budget-conscious projects or areas with significant temperature fluctuations.

Aesthetic Preferences: TPO’s variety of colors can provide more design flexibility.
