When the time comes that you need to have your roof replaced, there are things that you need to take note of. One of the most important factors that you need to consider is whether or not the new roof is going to meet or exceed building codes and insurance requirements.
Here’s a quick guide on the fire ratings of roofing systems to help you in making the right material choice for your roofing project.
Class A Fire Rating
A Class A roofing system is ideal for fire protection and is the preferred choice for any home. A roofing material with this rating means it can withstand severe fire exposure. To prove so, it must resist 15 cycles of a gas flame turned on and off, last up to four hours before ignition, and experience maximum flame spread of six feet. For your roofing project, make sure all components of the roof assembly have the same fire rating.
Class B Fire Rating
Roofing systems with the Class B fire rating are effective against moderate fire exposure. Pressure-treated shakes and shingles fall under the Class B rating, which means they resisted eight cycles of a gas flame turned on and off and lasted an hour before ignition.
Class C Fire Rating
This fire rating means that the roofing system can only provide light fire protection. Untreated wood shakes and shingles are common Class C building materials and are often not recommended as roof covering.
