Differences Between a Class A and Class B Roof Explained by Your Colorado Springs Roofer


March 8, 2017

When it comes to the type of your roof, it may be defined based on its fire resistance abilities. These are standards that have been put into place by Underwriters Laboratories (UL). UL is a global company that focuses on safety science. They provide safety and certifications for a wide variety of areas. One of those areas is roofing. Learn the differences between their Class A and Class B ratings, and when you need your Colorado Springs roofer.

What are roof ratings?

UL roof ratings are based on fire testing performed on roofing. By performing various tests, they can see how roofs handle a fire and how resistant they are to one. One of the drivers of ratings are the types of materials that are used to make up the roof. For instance, how will an asphalt roof hold up to a fire? These ratings are performed on all to see what happens in the event of a fire disaster. Some areas investigated in testing include what happens when flames are exposed to the construction materials and how quickly those flames spread. Learn more about testing in UL’s “UL 790 Standard for Standard Test Methods for Fire Tests of Roof Coverings.”

Class A

When it comes to premium fire protection, Class A roofs have earned the highest rating. They have achieved this through providing the best results through a variety of tests. If you are looking for a roof that has the most fire protection possible, you will want to consider Class A. This class of roof held up well in a test by being able to handle outside sources that were set around the building.

Class B

Class B roofing still has fire protection qualities. While they don’t stand up to the same standards as a Class A, they still provide some benefits. UL explains “roof coverings of this class afford a moderate degree of fire protection to the roof deck.” They add they don’t slip from their position either.

Upgrading Your Roof

When it comes to the safety of your structure, fire safety is a priority. Class C roofing exists that provides the least amount of fire protection. In these instances, roofing did not stand up to testing well and can be unsafe long term if exposed to a fire. Considering a Class B or Class A roof could help you to avoid extensive damage in the event of an accident.
