The use of cork or fibre board, or other approved insulation is permitted on top of the roof deck provided such insulation is covered with an approved type of fire resistive roof covering applied directly thereto, and that underlay of roofing is fastened through the insulation and into the roof deck. 706.2 Roofings which are classified as Class A,B, and C under the test specifications of the Underwriters Laboratories, Inc., shall be accepted as Class l, Class 2, and Class 3 coverings respectively.

Types of roofing not specifically mentioned, but which under tests are rated by the Underwriter's Laboratories, may be acceptable under the rated class. Within the limits of the first fire zone, a Class A roof is required, except for dwellings on which either a Class A or B type of roof will be permitted. Within the limits of the second fire zone, either Class A or Class B roof only will be permitted, depending upon the type of construction and class- ification and occupancy of the building. Outside the limits of the second fire zone, either Class A,B or C roofs will be permitted, depending upon the type of construction, classification and occupancy of the building. Class A includes roof coverings which are effective against severe fire exposures. Under such exposure, roof coverings of this class are not readily flamable and do not carry or commun- icate fire; afford ~ fairly high degree of heat insulation to the roof deck; do not slip from position; possess no flying brand hazard and do not require frequent repairs in order to maintain their fire resistive properties. Class B includes roof coverings which are effective against moderate fire exposures. Under such exposures, roof coverings of this class are not readily flsm_s_ble and do not readily carry or communicate fire, afford a m~derate degree of heat insulation to the roof deck, do not slip from position, possess no flying brand hazard, but may require infrSquent repairs in order to maintain their fire resistive qualities. ClaSs C includes roof coverings which are effective against light fire exposures. Under such exposures, roof coverings of this class are not readily flamable and do not carry or commun- icate fire; afford at least a slight degree of heat insulation to the roof d. eck$ do not slip from position; possess no flying brand hazard, and may require occasional repairs or renewals in order to maintain their fire resistive qualities. 706.3 ROof Coverings Ao General 1.
