Tab Shingles: fire rating?

Tab shingles, often made from asphalt, come with specific fire ratings that reflect their ability to resist ignition and help prevent the spread of flames. These fire ratings are designated by standards such as Class A, B, or C, with Class A being the highest rating indicating excellent resistance to fire. Most quality asphalt tab shingles will have at least a Class C rating, and many offer a Class A rating, which is especially important in areas prone to wildfires or where stricter building codes apply. This rating depends on the materials and manufacturing process, including a fiberglass mat base and the asphalt coating, which work together to resist fire. You can usually find the fire rating information on the packaging or the manufacturer’s product data sheets, which is something homeowners should check before purchase or installation.

To do a simple DIY check, look for the fire rating label when buying shingles or ask the store associate for products with a Class A fire rating if you live in a high-risk zone. Visually, you won’t notice much difference, but certification and manufacturer documentation are key. If you suspect your existing shingles don’t meet the required rating, or if damage from weather or age is compromising their integrity, it’s wise to call a professional roofer. When speaking to a contractor, ask directly: “Can you confirm the fire rating of these shingles, and do you provide certification documentation?” Also inquire, “Are you licensed and experienced in installing fire-rated roofing materials according to local building codes?” This helps ensure your roof is safe, meets warranty conditions, and complies with fire safety standards.
