Is Single Ply Roofing Fire Resistant?

Yes, many single ply roofing membranes can meet Class A fire ratings—the highest level of fire resistance—when installed with the right components.

Here’s what you need to know:

  • PVC membranes offer some of the best fire resistance. Their chemical makeup makes them naturally more flame retardant.

  • TPO and EPDM can also meet Class A ratings, but only when used with specific fire-rated insulation and underlayments.

  • Most fire ratings are not just about the membrane—they depend on the complete roof assembly, including:

    • Deck type (e.g., steel, wood)

    • Insulation (like polyisocyanurate)

    • Underlayment layers

  • Always verify the system's fire rating with the manufacturer’s documentation and confirm with Georgia’s local building codes.

If you're installing single ply roofing in Georgia—especially on commercial buildings in cities like Atlanta, Augusta, Macon, or Savannah—you’ll likely need to meet Class A fire requirements for code compliance and insurance purposes.


Why Fire Rating Matters for Georgia Roofs

  • Georgia summers are hot and dry, increasing fire risk, especially on commercial roofs with electrical equipment or HVAC units.

  • Building codes in many Georgia municipalities require Class A roofs for commercial or multifamily structures.

  • Insurance companies often provide lower premiums for Class A fire-rated systems.

FAQ

What is a Class A fire rating for roofing?

A Class A fire rating means the roofing system:

  • Resists severe fire exposure

  • Slows flame spread

  • Minimizes ember penetration

This rating is tested by recognized labs using ASTM E108 standards.


Do all single ply roofs automatically meet Class A?

No. Even if the membrane is fire-resistant, the assembly matters. A fire-rated underlayment or cover board may be required to achieve Class A certification.


Is fire resistance important for flat roofs?

Yes, especially for low-slope commercial roofs that may house:

  • Solar panels

  • HVAC units

  • Electrical conduits
    These increase fire risk if not properly protected.


How do I know if my roof system meets fire code?

Ask your roofing contractor to provide:

  • The UL or FM approval documentation

  • ASTM E108 test results

  • Confirmation from the membrane manufacturer
