About this detail

This parapet cap detail shows the roof edge assembly intersecting a masonry panel backed by framing. A perimeter steel channel specified as AESS Level C2, P2 supports the roof edge, accompanied by sheet metal flashing and a high-temperature membrane over a minimum one-half inch per foot slope. Metal clips, cant strips, and a continuous cleat secure the coping cap, which maintains a four-inch minimum overlap. A deflection joint with a three-quarter inch minimum gap accommodates movement below the parapet. Vents are spaced at one foot six inches on center along the assembly, referencing structural elevations at roof level forty-eight feet zero inches.
