Is modified bitumen fire-resistant?
FAQ: Is Modified Bitumen Roofing Fire-Resistant?
Q: Is modified bitumen roofing fire-resistant?
A: Yes. Many modified bitumen roofing systems can achieve a Class A fire rating—the highest rating—when installed with approved underlayment and assembly methods.
This means they can provide strong protection against the spread of fire from external sources like wind-blown embers.
Key Points for Florida Homeowners:
Class A Rating – Requires tested combinations of the membrane, underlayment, and deck materials.
Torch-Applied Sheets – Offer excellent adhesion but require strict fire safety during installation.
Safer Installation Options – Self-adhered and cold-applied modified bitumen reduce open flame use.
Roof Nuts Standards – We only install fire-rated products and follow manufacturer and code-compliant fire safety practices from start to finish.
Why Fire Resistance Matters in Florida
Wildfire Ember Risk: Even though wildfires are less common in many Florida cities, wind-driven embers can still ignite roofs.
Urban Fire Spread: In dense neighborhoods, a fire in one home can quickly threaten another.
Hurricane Aftermath Fires: Storm damage can lead to electrical shorts and fires, making a fire-resistant roof another layer of protection.
