We also fabricate the two details that go hand in hand with parapet drainage: roof saddles (crickets) that divert water around chimneys and curbs toward the drains, and door pans that protect exterior door openings at the threshold. All three are made to your field dimensions or architect drawings.

Common Applications
Scupper Types We Fabricate
Every scupper on this page is brake-formed at our Portland shop to the dimensions you give us. Send the parapet wall thickness, face height, and inside opening width, and we fabricate the complete sleeve ready to install.
Through-Wall Scuppers
The standard scupper drain on a parapet roof: a formed metal sleeve that passes through the parapet wall and carries water off the roof surface. Fabricated to your exact wall thickness and opening size in galvanized steel, stainless, or copper, with the flange configuration your membrane system needs.
Open-Top & Closed-Top Scuppers
Open-top scuppers sit at the top edge of the parapet and take water over the wall. Closed-top scuppers are fully enclosed openings lower in the wall. We fabricate both, sized to your opening and membrane height, so the roofer can tie the membrane in cleanly.
Overflow Scuppers
Secondary drainage for when the primary drain or scupper clogs. Overflow scuppers are set above the primary drainage level per IPC code requirements, and they are usually the detail an inspector looks for on a parapet roof. We fabricate them alongside your primary scuppers so the whole drainage package matches.
Scupper Boxes & Collector Heads
The formed box that mounts on the outside wall under the scupper outlet, catches the discharge, and funnels it into a downspout. Also called collector heads or leader heads. We fabricate scupper boxes to your scupper size and downspout dimensions so the whole assembly fits together the first time.
