Fire resistance is an important aspect of modern buildings that helps keep not only buildings safe, but also the people and property inside. Not all materials are the same, meaning the degree to which your roof is fire resistant depends on the what it is made of. In this article, the A.O. Roofing team will take a closer look at the fire resistance of different roofing materials to help you better understand which is right for your home.
Understanding Fire Rating Standards
When it comes to the fire resistance of your roof, there are four different classes:
- Class A, the most resistant
- Class B, moderately resistant
- Class C, slightly resistant
- Unrated, which have little to no fire resistance
Generally speaking, you should avoid Class C or unrated materials; Class A and B materials are highly effective against fires, and feature plenty of affordable options.
Popular Roofing Materials and Their Fire Resistance
Let’s take a look at some of the most common roofing materials and how they stack up when it comes to fire resistance.
Metal Roofing
Not surprisingly, metal roofing systems are among the most fire-resistant materials and will almost always be Class A. Metal won’t combust in a house fire, and requires very high, sustained heat to melt.
Asphalt Shingles
Asphalt shingles are one of the gold standards of roofing, and this is also true when it comes to fire resistance. Practically all asphalt shingles on the market today have a Class A fire resistance rating.
Slate
Slate is a natural stone material that is not only fire resistant, but durable and aesthetically pleasing to boot. Along with metal, it’s one of the longest lasting roofing materials, but it is also costly, heavy, and requires experienced professionals with specialized knowledge to install them properly.
