When it comes to commercial roofing, two systems stand out: TPO (Thermoplastic Polyolefin) and EPDM (Ethylene Propylene Diene Monomer). Both are single-ply roofing membranes, but each offers unique benefits. Let’s delve into the specifics of each system to help you make an informed decision for your commercial building.

TPO Roofing Systems: An Overview

TPO roofing is a blend of polypropylene and ethylene propylene rubber. These sheets are heat-weldable and come with reinforcements of polyester. They also contain UV stabilizers, fillers, pigments, and flame retarders.

Key Features of TPO Roofing

  • Variety in Appearance: TPO membranes are available in shades of white, gray, and tan. They come in thicknesses of 45, 60, or 80 mil.
  • UV Resistance: TPO roofing is known for its excellent resistance to UV rays. It can reflect almost 87% of these rays, making it a preferred choice for those aiming to cut down on cooling costs.
  • Durability: TPO roofs resist environmental pollutants, chemicals, abrasions, tears, and punctures. With proper maintenance, a TPO roof can last between 20-30 years.

EPDM Roofing Systems: What You Need to Know

EPDM roofing, often referred to as a rubber roof, is crafted from industrial-grade synthetic rubber. Its primary ingredients include ethylene, propylene, and carbon black, sourced from oil and natural gas.

Key Features of EPDM Roofing

  • Flexibility: EPDM roofing is known to expand and contract with temperature fluctuations.
  • Variety in Size: EPDM membranes come in black or white and are available in extensive lengths, with some sheets measuring up to 50′ x 200′. They are available in thicknesses of 45, 60, and 90 mils.
  • Longevity: A well-maintained EPDM roof can last over 30 years, making it a long-term investment for commercial properties.
