Roof Fire Ratings
Roof fire ratings are established by test methods to ensure that certain standards are formalized to protect human life and property. The American Society for Testing and Materials (ASTM) Standard E108 is one such test method and materials are classified as a Class A, Class B or Class C Fire rating through this method. Class A is the highest, whereas Class C is the lowest. A roofing product that has Class A Fire rating meets all three requirements which are: ability to resist spreading of flames on surface, ability to resist fire penetration from the exterior to the underside of the rock deck and ability to resist recurring intermittent flame. DaVinci Roofscapes offers manufactured slate tile that has Class A or Class C Fire Rating according to ASTM E108 specifications.
Only materials that will guarantee your safety and the safety of your property and surrounding properties during a fire should be used for roofing. This will help to avoid lawsuits and frustrations from choosing the wrong type of materials. It is also important to be fully aware of specific state laws and see how they apply to different types of buildings and your roofing project.
