Description: Scuppers are used to provide an outlet through parapet walls or gravel stops on flat and built-up roofs to allow drainage of excess water. They can be used in conjunction with gutters and downspouts to divert the flow to the desired location.
Unlike internal drains which carry water through the building via pipes, scuppers direct the water out and away from the building exterior. They are particularly effective in managing water runoff from flat or low-sloped roofs, where water cannot easily flow off the roof surface by gravity alone.
By the way, a scupper is different from a drain because a drain forces excess water into an enclosed location like a pipe or sewer system. A scupper simply spits it away from the building. The water hits the ground and runs off or soaks into the earth.
The main function of a scupper is to help drain rainwater from flat roofs. Scuppers are often located at the edges of roofs or incorporated into parapet walls. They allow water to escape and flow away from the building.
The difference? It's all about how the water is directed into it. You see, a gutter is filled from the top, where as a scupper is simply a hole cut into the side of a wall as an outlet for water. In commercial buildings with flat roofs, this is the most efficient way to drain the water pooling up on the roof.
The main scupper that requires a downspout is the through-wall scupper. The water will travel through the scupper off the flat roof and into the downspout.
Scuppers are located in the gutters or waterways, on open decks and connected to pipes usually leading overboard, and, in the corners of the enclosed decks to the bilge.
Each scupper shall be sized with a height of 4 inches minimum and width of equal to the circumference of the roof drain required for the area served, sized in accordance with a 3 inch per hour rainfall rate in Table 1101.12 of the Plumbing Code.
A roof scupper is an important part of any roofing system and provides many benefits. Firstly, it is a simple, affordable, and effective way to drain water off your roof. Secondly, roof scuppers prevent water ponding that causes damage to your roof membrane.
Maintenance Tips For Roof Scuppers
Regularly cleaning and inspecting roof scuppers is important to make sure there is the right amount of drainage, and prevent any further damage to the roof. This includes checking for blockages, rust, and proper water flow to ensure water is directed away from the building.
A boat drain plug, also known as a plug for boat drain or drain for boat plug, is a device inserted into a hole in the bottom of a boat to allow water to flow out. It is a crucial component of a boat, keeping it from filling up with water and sinking.
Scuppers can also be provided as primary or secondary drainage points. Scuppers are rectangular openings in parapet walls that are a minimum of 4 inches in width and height ranging from 4 to 6 inches. If the scuppers are used as primary drainage, then they are applied flush with the roof level.
The size of overflow scuppers must be able to handle the anticipated rainfall event (considering the primary scupper or vertical drains are 100% clogged). Their inlet elevation shall be not less than 2 in. nor more than 3 in. above the low point of the adjacent roof surface.
Gutters and Scuppers (Sloped Roofs)
Scuppers are installed on the walls of the building and are designed to direct water toward the gutters and downspouts. Homeowners will benefit from added damage protection with well-maintained, clean, and functional gutter systems.

scup·per ˈskə-pər. 1. : an opening cut through the bulwarks of a ship so that water falling on deck may flow overboard. 2. : an opening in the wall of a building through which water can drain from a floor or flat roof.
If you plug your scupper holes, the water is prevented from coming up in the holes, as well as prevented from draining out of them. When you plug the scupper holes, your kayak will sit higher on the water. When they're unplugged, you'll sit a bit lower on the water.
In addition, overflow scuppers must be sized with a minimum opening height of 4 inches (102 mm) and have an opening area at least three times that of the roof drains. The International Plumbing Code®(IPC®) sets forth the specific details for the installation and sizing of overflow drains, leaders and conductors.
Explanation: Before lighting a Bunsen burner, the air hole should be closed to prevent gas buildup and ensure a proper flame structure. This helps in controlling the amount of air mixed with the gas, leading to a more efficient and safer combustion process.
A scupper is an opening in the side walls of a vessel or an open-air structure, which allows water to drain instead of pooling within the bulwark or gunwales of a vessel, or within the curbing or walls of a building.
Scupper downspouts are drainage devices installed on buildings, primarily used to direct water away from roofs. These structures differ from conventional downspouts; they are openings in the side walls of a building or parapet walls, allowing water to exit directly from the roof surface.
4.1 Overflow Drains and Scuppers.
When placing roof drains, it is good design practice to locate the drains no more than 50 feet from the roof perimeter, nor more than 100feet apart. It is important to remember that no roof area should ever have less than two roof drains.
