Section 1505.1, General Title 24, Part 2 is revised as follows: Roof assemblies shall be divided into two classes based on their ability to resist fire exposure:

Class B—Roof assemblies provide moderate fire resistance, effective against moderate fire test exposures. These assemblies offer acceptable protection against flame spread and reduce the likelihood of fire penetration.

Class A and Class B assemblies shall be tested in accordance with ASTM E 108 or UL 790. In addition, fire- retardant-treated wood roof coverings shall be tested in accordance with ASTM D 2898. The minimum class of roof coverings installed on buildings is Class B, and shall comply with Table 1505.1, based on the type of construction of the building.
