From Asphalt Shingles to Zinc Strips

TPO vs. EPDM Roofing: Which Is Best for Your Commercial Building?

When it comes to choosing the right roofing material for your commercial building, there are many factors to consider. Two popular options that often come up in the discussion are TPO (Thermoplastic Olefin) and EPDM (Ethylene Propylene Diene Monomer) roofing. Both offer their own set of advantages and disadvantages, so it's important to weigh the pros and cons before making a decision.

Durability and Longevity

TPO roofing is known for its durability and resistance to mold, dirt, tears, and punctures. It can withstand extreme weather conditions, including UV rays, high winds, and hailstorms. EPDM roofing is also durable but may be more prone to punctures and tears compared to TPO. However, EPDM has a longer track record in terms of longevity and has been proven to last a few decades with proper maintenance.

Installation and Maintenance

Both TPO and EPDM roofing systems are relatively easy to install compared to other types of commercial roofing materials. TPO is typically installed using heat-welded seams or adhesive bonding, while EPDM is installed using ballasted, mechanically attached, or fully adhered methods. In terms of maintenance, both materials require regular inspections and repairs to ensure their longevity.

Energy Efficiency

TPO roofing is known for its energy-efficient properties. It reflects sunlight rather than absorbing it like traditional asphalt roofs, which can help reduce cooling costs during hot summer months by keeping the building cooler. EPDM roofing also offers some level of energy efficiency but may not be as reflective as TPO.


When it comes to cost, TPO roofing tends to be slightly more expensive upfront compared to EPDM. However, the long-term savings on energy costs due to its reflective properties may offset the initial investment over time. On the other hand, EPDM roofing is more budget-friendly upfront but may require more maintenance in the long run.

Environmental Impact

Both TPO and EPDM roofing materials are considered environmentally friendly options for commercial buildings. They are recyclable at the end of their lifespan and do not emit harmful chemicals into the environment during installation or use, making them a sustainable choice for eco-conscious property owners.


In conclusion, both TPO and EPDM roofing systems have their own set of advantages and disadvantages when it comes to durability, installation, energy efficiency, cost, and environmental impact. Ultimately, the best choice for your commercial building will depend on your specific needs and budget constraints.
