If you want to keep your family and assets safe from the outdoor elements, you should invest in a roofing material that has a good fire rating. Roofing materials that don’t have it may be more enticing since they’re cheaper, but you won’t get the protection needed against a raging fire. Unrated roofs are more vulnerable, which means fires can spread faster to other parts of your home.
It helps to know the different fire ratings on roofing materials to understand what you should get for your home.
Roofs with a Class A rating can withstand a burning brand that measures 12 inches by 12 inches and weighs 2,000 grams. They last around two to four hours before they ignite. They can experience a maximum flame spread of 6 feet and endure 15 cycles of a gas flame turned on and off. Roofing systems with this rating are highly recommended for any type of residential property that’s near woodlands, forests or any area prone to wildfires. Examples include tiles and even asphalt fiberglass composite shingles!
Roofs with this rating are also recommended by contractors providing roof installation services because of their moderate effectiveness against fire exposures. They resist 8 cycles of a gas flame turned on and off and can withstand a burning brand measuring 6 inches by 6 inches and weighing 500 grams. They can also experience a maximum flame spread of 8 feet, which can last about an hour before ignition. Pressure-treated shakes and shingles usually fall under this rating.
Class C roofs offer only the bare minimum in fire protection. They can experience a maximum flame spread of 13 feet and can last 20 minutes before they ignite. They can also withstand a burning brand weighing 0.25 grams and measuring 1.5 inches by 1.5 inches. Class C roofs only resist about three cycles with a gas flame turned on and off.
