Roof framing layout details the structural support and slope adjustments around a scupper opening. Joists are positioned per structural drawings with specific framing added to create a low spot sloping at one quarter inch per foot across the drainage path. Dimensions of one foot four inches flank the centerline of the plumbing or projection joint, spanning a total height of three feet six inches. Roof plans dictate exact locations while additional framing ensures positive drainage toward the scupper.
