The roof and parapet intersection at the fourth floor level establishes the transition between the exterior wall assembly and the roof structure. A structural beam supports the floor assembly, which is insulated with foamed-in-place insulation and timber blocking. Exterior cladding is supported by two-inch nominal wood furring over a water-resistive barrier that laps over the counter flashing. Vertical dimensions note an eight-inch spacing offset and a two-inch clearance zone within the flashing assembly. The fourth floor elevation is established at four hundred sixty-eight feet and seven and three-quarters inches.
