How Do I Know If My Roof Scupper Membrane Is Causing a Leak?

When it comes to flat roofs, water always finds the weakest point — and on one recent project, that weak point was a scupper. At Anchor Point Roofing — the Number 1 roofing company in Chicago and your go-to roofing company — we caught the problem early, repaired it fast, and protected the building from serious water damage. Here's the full story

First Things First: What's a Scupper?
A scupper is a metal drain opening built into the edge or wall of a flat roof. Its job is simple: give rainwater and melting snow a clear exit path off the roof. Think of it as a doorway for water — when it works, water leaves. When it doesn't, water stays, pools, and starts looking for a way into your building.

The Repair
Our team started by cutting and removing the damaged modified bitumen membrane from the scupper area — a lasting repair can't be built on failing material. We then applied new asphalt primer to the scupper to ensure solid, long-lasting adhesion. Next, we installed new heat-welded modified bitumen membrane on each side of the scupper, fusing it into one continuous, watertight seal with no gaps for water to sneak through. To finish, we applied a new aluminum coating to the affected area, shielding the repair from UV rays and harsh weather for years to come.

Why It Matters
A lifted membrane at a scupper is one of the most common sources of flat roof leaks. This prompt, professional repair stops water infiltration, prevents costly interior damage, and extends the life of the roof — right where water flows the most.
