Roof scuppers play a vital role in collecting and controlling rooftop water on flat or low-sloping roofs, as well as helping protect against expensive repairs and prolonging the lifespan. But What are Scuppers on a Roof? This guide describes what they are and their purpose, different types, advantages, and how to maintain one to keep the property secure and dry.
What Is a Roof Scupper?
A roof scupper is an opening in a parapet or roofline where water runs off a flat roof or low-slope roof. Since the flat roofs do not run off water like a sloping roof does, the scuppers are a crucial element to prevent stagnant water that would lead to structural deterioration.
The Working of Roof Scuppers
Flat roofs do not allow the drainage of rain or snow meltwater, causing the stagnation of water. This water is directed to the holes in the parapet wall by scuppers. The water may be directly connected to downspouts to drain it under closed conditions, or splash blocks made through leader heads to safely spread it into the surrounding land. This efficient mechanism dries off roofs and keeps them intact.

Common Roof Scuppers
There are a variety of roof scuppers, each designed for particular purposes:
- Through-wall scuppers:
Pierced through parapet walls straight through, letting water drain cleanly. - Channel-type scuppers:
Box- or trough-shaped, sometimes tied into downspouts for efficient drainage. - Overflow scuppers:
Higher up on the parapet as an alternate to catch overflow water if the main drains become clogged.
These variations provide adaptability for a variety of roof designs.

Maintenance Tips & Code Essentials
Regular maintenance is important to maintain effective scuppers. Remove debris such as leaves or soil to avoid clogs, which can lead to backup water. Scuppers are properly sized and located according to building codes, including the International Building Code (IBC). Copper is a durable material, but it must still be checked on occasion to confirm correct function.
Installing scuppers demands accuracy: proper flashing, sealing, and sizing are essential to avoid leaks and code compliance. DIY is an option, but errors may result in expensive repairs.
