About this detail

A scupper penetration through a parapet wall features a PVC roofing membrane that wraps up and over the parapet. A two-inch-deep tapered sump at the scupper opening maintains a minimum R-38 value with a quarter-inch-per-foot slope toward the scupper box. A pre-finished metal coping with hemmed drip edges is bedded in water-cutoff mastic and secured with approved roofing manufacturer adhesive and single-ply sealant. A four-by-eight-inch blockout accommodates the PVC-clad scupper box, connecting to a conductor head and downspout.
