Expert Verdict — Reviewed by the SuperArbor Pro Desk
Through-wall scuppers are a dependable primary or overflow drainage path on parapet-walled commercial roofs, and many codes require overflow scuppers in addition to primary drains. Frame the wall opening accurately to the 4" x 4" x 12" body and terminate the scupper to discharge clear of the wall face. Detail the TPO flashing properly at the membrane-to-scupper transition to prevent leaks.
Roof and parapet work requires fall protection; heat-welding TPO should be done only by trained roofing personnel.
Order the FlashCo 4" x 4" x 12" TPO Through-Wall Scupper in white for your commercial drainage details.
