FAQs
What fire rating do metal roofs typically achieve in Maryville?
Most quality steel and aluminum roofing panels carry a Class A fire rating—the highest possible classification under ASTM E108/UL 790 testing. A Class A system resists severe exposure to fire originating outside the structure, making it an excellent choice for homes and businesses in and around Maryville, where local building officials follow the International Residential Code (IRC) and International Building Code (IBC) fire-safety requirements.
Does a metal roof need additional underlayment to maintain its Class A fire rating?
Yes. While the metal panels themselves are non-combustible, a complete Class A assembly also depends on the right fire-rated underlayment (often a fiberglass-reinforced or mineral-surfaced product) and proper installation over rated decking. Our crews use only underlayments that have been tested with the exact panel profile we install, ensuring the finished roof keeps its listed fire rating.
How does a metal roof’s fire performance compare with asphalt shingles or wood shakes?
Metal roofs outperform most conventional coverings. Standard three-tab asphalt shingles usually carry a Class C rating unless special fire-resistant versions are specified, and untreated wood shakes often fail to meet any rating at all. Metal, by contrast, is non-combustible, will not spark or ignite when hit by flying embers, and sheds burning debris quickly thanks to its smooth, interlocking panels.
Will installing solar panels or rooftop equipment compromise my metal roof’s fire rating?
Not when it’s planned correctly. Penetrations for PV mounts, HVAC units, or satellite dishes must be flashed with fire-rated materials and sealed per the manufacturer’s listing. We coordinate with your solar or mechanical contractor to use UL-listed mounting brackets and maintain required clearances, so the overall roof assembly keeps its original Class A classification.
Are there local incentives in Maryville for upgrading to a Class A metal roof?
Blount County’s Building & Codes Department does not currently offer direct rebates, but many insurers give premium discounts—often 5–15 %—for homes protected by Class A metal roofing because it reduces the risk of fire claims. In addition, some energy-efficiency programs, such as TVA’s EnergyRight, recognize cool-roof metal coatings that often accompany fire-rated panels, adding further savings.
How long does the fire rating last, and does maintenance affect it?
The rating is tied to the assembly, not a time period, so it remains valid for the life of the roof—typically 40–70 years for metal—provided the system is kept in good repair. Annual inspections to tighten fasteners, clear debris from valleys, and replace any damaged sealant are all that’s required. Alterations like adding skylights or attic vents should be handled by qualified installers to preserve the original Class A listing.
