Fire Resistant Roofing Shingles

If you live in an area where your home can easily be exposed to fire, such as a region prone to forest fires, it makes a lot of sense to get the best types of building materials that can withstand heat and open flames. For that purpose, Class A and Class B roofing is the best.  It’s good to note that a local roofing contractor can provide information about specific roofing materials necessary for your area.

 

There are three main roof fire ratings to speak of:

 

  • Class C, which only provides light fire protection and ignites after 20 minutes of exposure to an open flame
  • Class B, ensuring a maximum flame spread of about 8 feet and the ability to maintain its structural integrity for an hour before being damaged by the flames
  • Class A, which is represented by the strongest fire-retardant roofing products, capable of resisting 2-4 hours before ignition and to withstand a burning brand weighing up to 2,000 grams.

 

Your best choice for forest fire protection is, of course, a class A material. These types of shingles include materials such as clay, asphalt glass fiber shingles and slate. If you want to avoid the expenses associated with a Class A material, but still get enough fire protection, a better option would be to buy pressure-treated shakes and shingles, which commonly fall under the Class B category.
