Which standard is used to evaluate flame spread in roofing materials?

Flame spread performance of roofing materials is assessed with a tunnel-type fire test that measures how fast flames travel along the material in an exposed roof scenario. The standard that specifies this method is UL 790, the Steiner tunnel test for roof covering materials, which yields a flame spread rating used in roofing approvals. Other options aren’t as suitable: NFPA 285 targets exterior wall assemblies rather than roof coverings; ASTM E84 evaluates interior surface burning characteristics and isn’t applied to roofing materials in the same exterior-fire context; ASTM D4060 covers abrasion resistance of coatings, not flame spread.
