Wood shingles are rated by which NFPA standard?

Wood shingles are rated according to NFPA 256, which is the standard that covers the testing and classification of the fire resistance of roof coverings, including wood shakes and shingles. This standard is crucial because it provides guidelines for determining how various materials will perform when exposed to fire. The intent is to ensure that roofing materials can resist fire spread adequately, thus increasing safety in buildings constructed with such materials.

Understanding this rating system is important for fire inspectors, as they must be able to evaluate the fire performance characteristics of roofing materials in order to enforce building codes and help prevent fire hazards. Knowing which materials meet the necessary standards aids in making informed decisions about fire safety and compliance during inspections.
