Expert Verdict — Reviewed by the SuperArbor Pro Desk
Galvanized center scuppers are a workhorse detail for parapet drainage on commercial low-slope roofs. Verify that the 12 in. throat depth matches your wall thickness and that the 4 x 6 opening meets your drainage calc. Seal the flange to the membrane or flashing per SMACNA practice, and consider a scupper liner in protected-membrane assemblies.
Cut edges of galvanized sheet metal are sharp—wear cut-resistant gloves and eye protection during handling and installation.
