Choosing the right roofing system for your Atlanta commercial building is a significant decision that impacts your property's value, energy efficiency, and long-term maintenance costs. With several options available, understanding the differences between TPO, EPDM, PVC, and other systems helps you make an informed choice.

TPO (Thermoplastic Polyolefin)

TPO has become one of the most popular commercial roofing solutions in Atlanta and across the country. This single-ply membrane offers an excellent balance of performance and value.

Key Benefits:

  • Excellent energy efficiency – reflects heat and reduces cooling costs
  • Heat-welded seams provide superior waterproofing
  • Resistant to UV rays, ozone, and chemical exposure
  • Available in various thicknesses (45, 60, 80 mil)
  • Cost-effective compared to many alternatives

EPDM (Ethylene Propylene Diene Monomer)

EPDM, often called "rubber roofing," has been a trusted choice for decades. It's particularly well-suited for buildings with flat or low-slope roofs.

Key Benefits:

  • Exceptional durability – 20+ year lifespan common
  • Excellent resistance to UV, ozone, and weathering
  • Flexible in extreme temperatures
  • Lower initial cost than many alternatives
  • Easy to install and repair

PVC (Polyvinyl Chloride)

PVC roofing offers premium performance, particularly in environments with exposure to chemicals, grease, or high traffic.

Key Benefits:

  • Superior chemical and grease resistance
  • Excellent fire resistance properties
  • Heat-welded seams create watertight bonds
  • Long lifespan with minimal maintenance
  • Ideal for restaurants and industrial facilities

Other Systems to Consider

Modified Bitumen

A multi-ply system that combines asphalt with rubber modifiers. Offers excellent durability and is ideal for roofs with heavy foot traffic.

Built-Up Roofing (BUR)

Traditional hot-tar roofing using multiple layers of bitumen and gravel. Proven performance over many decades, though installation is more labor-intensive.

Metal Roofing

Standing seam metal roofs offer exceptional longevity (40+ years) and are excellent for sloped roof applications.

Which System Is Right for Your Atlanta Building?

The best roofing system depends on multiple factors:

  • Building type and use (warehouse, office, retail, etc.)
  • Budget constraints and long-term cost considerations
  • Energy efficiency goals and climate considerations
  • Roof size, slope, and existing structure
