Which Should You Choose?

The right choice depends on your building's specific needs, location, and budget.

Choose TPO If...

  • Your building is in a hot climate like the Southeast
  • Energy efficiency and cooling cost reduction are priorities
  • Your roof has multiple penetrations or complex details
  • Chemical exposure is a concern (restaurants, industrial)
  • You want a white reflective roof for LEED certification

Choose EPDM If...

  • Budget is the primary concern
  • Your building has a simple, open roof design
  • Heavy rooftop equipment requires frequent maintenance
  • No concerns about chemical exposure
  • You're in a cooler northern climate
