Flat Roof Scuppers: The Key to Optimal Water Management and Building Protection


In modern architecture, the flat roof is very popular, and flat roof repairs are just as common. Even more attractive is the installation of a flat circulating roof, transformed into a garden or other type of relaxation area. However, many people are still reluctant about opting for this type of roof, especially because of preconceived notions about its drainage capabilities.

It is good to know that roofing materials and technologies have been very much improved along the years, to the point that nowadays you can get optimal protection regardless of the type of roof you choose.

Qualified Orlando commercial roofing contractors confirm that there are actually several ways to drain a flat roof:

  • Inner Drains
  • Gutters
  • Siphonic Roof Drains
  • Scuppers

A roof scupper is a flat roof drainage system that allows the water runoff from the surface of the roof to exit, through the deck or through a parapet wall, into a downspout. This system formed by scuppers and downspouts is very efficient for collecting the water and preventing it from leaking down the walls.

Scuppers have a few significant advantages compared to other flat roof drainage options with a lower cost. Some models are wide enough for leaves and twigs not to get stuck and block the water drainage flow.

What are scuppers on a roof?

When it comes to roofing systems, effective drainage is paramount to safeguarding the structural integrity and longevity of any building. Scuppers are a vital component of a roof’s drainage system, playing a significant role in efficiently directing water away from the roof’s surface. In this article, we’ll explore what scuppers are, how they function, and their importance in maintaining a water-tight and robust roofing system.

What are Scuppers? A roof scupper is a type of drainage system that allows water to flow off a flat or low-sloped roof. Scuppers are typically located near the edges of the roof, and designed to direct water away from the building. Roof scuppers prevent water from pooling on the roof and causing costly damage to your roof membrane.

Typically scuppers are made of metal, PVC, or other durable materials. They provide an alternative to traditional gutters and downspouts, serving as a simple and effective solution for managing rainwater on flat or low-sloped roofs.

How do Scuppers Work? During rainfall or snowmelt, water accumulates on the roof’s surface. Scuppers create a pathway for this water to exit the roof, preventing ponding or excessive weight that could lead to structural damage over time. As gravity pulls the water downward, it flows through the scupper openings and safely evacuates from the roof. This process not only protects the roof from potential leaks and water-related issues but also reduces the risk of water infiltration into the building.

Key Advantages of Scuppers:

  1. Simplicity: Scuppers are relatively straightforward in design and installation, making them cost-effective compared to complex gutter systems.
  2. Low Maintenance: With no moving parts, scuppers require minimal maintenance, reducing long-term upkeep costs.
  3. Enhanced Drainage: Scuppers facilitate faster and more efficient drainage, preventing water buildup and reducing the risk of water-related damage.
  4. Aesthetic Appeal: As scuppers are often integrated seamlessly into the roof’s design, they can add a touch of architectural elegance and visual appeal.
  5. Scuppers vs. Gutters: While gutters are a popular choice for roof drainage, scuppers offer distinct advantages. Gutters require regular cleaning to prevent clogs, which can lead to overflow and potential damage. In contrast, scuppers do not accumulate debris, eliminating the need for frequent maintenance. Additionally, scuppers are less prone to damage from ice buildup, as they lack the long, horizontal sections vulnerable to expansion and contraction.

Scuppers are indispensable elements in a roof’s drainage system, providing a reliable and cost-effective solution for managing rainwater and protecting the integrity of the roof and the building it shelters.

Their simplicity, efficiency, and low maintenance requirements make them a valuable choice for architects, builders, and property owners seeking effective water management solutions. Whether designing a new roof or upgrading an existing one, considering scuppers as part of the drainage strategy can contribute to a resilient and long-lasting roofing system.

Get the Scoop on Roof Scuppers: The Benefits and Advantages

Roof scuppers are an important part of a building’s drainage system and help to prevent water damage to the roof and structure. They are especially important in areas where there is a lot of rainfall or snowmelt. Without a scupper, water would pool on the roof and could eventually leak into the building, causing damage to the ceiling and walls.

Do you know the purpose of a roof scupper?

A roof scupper is a drainage feature installed on the edge of a flat or sloped roof. Its purpose is to allow water to drain off of the roof and away from the building, preventing leaks and water damage.

There are two main types of roof scuppers: internal and external. Internal scuppers are located within the perimeter of the roof, while external scuppers are located outside of it. Both types of scuppers serve the same purpose, but they differ in how they are installed and how they function.

Internal scuppers are typically installed along the inside edge of a parapet wall or other barrier that surrounds the perimeter of the roof. They are usually made of metal or plastic and have a grated surface that allows water to drain through while keeping debris out. Internal scuppers typically have a minimum width of 4 inches (10 cm) and a minimum height of 6 inches (15 cm).

External scuppers are typically installed along the outside edge of a parapet wall or other barrier that surrounds the perimeter of the roof. They are usually made of concrete, stone, or brick and have an open top that allows water to drain through. External scuppers typically have a minimum width of 6 inches (15 cm) and a minimum height of 8 inches (20 cm).

While both internal and external scuppers serve the same purpose, there are some advantages and disadvantages to each type. Internal scuppers are less likely to become clogged with debris than external scuppers, but they can be more difficult to install and maintain. External scuppers are easier to install and maintain, but they may be more likely to become clogged with debris.

When choosing between internal and external scuppers, it is important to consider the specific needs of your building and your climate. If you live in an area with high winds or heavy rains, you may want to choose an external scupper so that water can drain off more quickly. If you live in an area with light rains or snow, you may want to choose an internal scupper so that water can drain off more slowly and less debris will be able to enter it.
