Roofed Right knows you need roof that lasts in a material that matches your style and budget. Both EPDM and TPO are widely used for commercial buildings for their longevity and energy efficient properties.

TPO Roofing Systems

TPO stands for Thermoplastic Polyolefin and is in a broad family of rubber roofing materials. It is widely used because it is cost effective and is highly reflective making it ENERGY STAR ® certified. Its white color allows it to absorb heat in winter and reflect heat in summer, keeping energy bills down.

Benefits of TPO include:

  • Energy efficient
  • Heat-welded (can be installed in any weather)
  • Stronger seams than EPDM
  • Variety of color options

Disadvantages of TPO:

  • Known to shrink & pull away from seams
  • Requires special installation equipment
  • Constantly changing formulas

Repairs and installations are easier with a TPO system than EPDM. TPO can be installed in a variety of ways including mechanically attached, adhered or heat-welded. So weather does not impact repairs like it does with EPDM. Roofed Right’s maintenance service and heat-welding equipment allow for TPO roof repairs any time of year.

EPDM Roofing Systems

EPDM stands for Ethylene Propylene Diene Monomer and is a synthetic rubber derived from oil and natural gas. This recyclable rubber material makes for a durable single ply roofing system for any commercial roof. The main benefit of EPDM in comparison to TPO roofing systems is the lower cost.

Benefits of EPDM include:

  • High resistance to ozone, weathering, wind and hail
  • Flexible in low temperatures
  • Thermal shock durability
  • Superior resistance to extreme heat and fire
  • No special installing equipment

An advantage of TPO roofing systems is the white color. The majority of EPDM roofs are black, though color coatings are available. If left black, EDPM can melt small amounts of snow in the winter, but will also absorb heat in the summer when you want the opposite.
