About this detail

A skylight mounts to a two-by-eight wood curb resting over plywood sheathing and roof framing. The assembly features an SBS modified flashing sheet over plysheet reinforcement, with base flashing attached at six inches on center over built-up roofing. Fasteners secure the skylight through neoprene washers at spacings recommended by the manufacturer. A metal counter flashing protects the top of the curb, and minimum one-half-inch round burglar bars are mounted at five inches on center. Simpson straps are tied to the curb per structural drawings, with one strap per corner and additional straps provided on the long side as typical.
