The Difference Between Scuppers and Gutters on Arizona Roofs

The Difference Between Scuppers and Gutters

When it comes to roof drainage in the Grand Canyon State, homeowners and business owners alike have a primary question: “Should I go with scuppers or gutters?” Given Arizona’s unique desert climate, punctuated by intense monsoon rainfalls, understanding these two drainage systems is essential. Let’s break down the distinctions between scuppers and gutters, especially in the context of Arizona roofs.

Scuppers: The Direct Drainers

What Are Scuppers?

Scuppers are simply openings or outlets made in the edge or a parapet wall of a flat or low-sloped roof, enabling water to flow directly off the side.

Why Are Scuppers Suited to Arizona?

Arizona sees a significant number of flat or low-sloped architectural structures, particularly in its modern designs. Scuppers provide rapid drainage during Arizona’s intense monsoon season, preventing water accumulation and subsequent roof damage.

Aesthetic and Functional Balance

Often, scuppers are integrated into the building’s design, offering an aesthetic appeal while serving their functional purpose. They can be adorned with decorative spouts, giving Arizona buildings a blend of modern and Southwestern flair.

Gutters: The Collectors and Guiders

What Are Gutters?

Gutters are attached trough-like structures that run along the roof’s edge. They collect rainwater and guide it, through downspouts, away from the foundation of the building.

Why Are Gutters Suited to Arizona?

While scuppers offer direct drainage, gutters provide a controlled channeling of water, especially vital in areas prone to soil erosion. Given Arizona’s sudden downpours, gutters can manage and redirect vast amounts of rainwater, protecting landscapes and building foundations.

Versatility in Design

Available in a variety of materials and styles, gutters can be tailored to match the architectural vibe of any Arizona home, from traditional to contemporary.

Are Gutters or Scuppers Best for My Tucson Roof?

The choice between scuppers and gutters often depends on the roof’s design and the specific drainage needs of the building. In some cases, a combination of both might be the ideal solution, especially for larger structures or those with varied roof slopes.

When in doubt, consult with a local Arizona roofing expert like . They can provide insights tailored to your building and its environment, ensuring you have an effective drainage system in place when those Arizona monsoons roll in.


Both scuppers and gutters offer unique advantages, and understanding these can help Arizonans make informed decisions about their roofing drainage systems. Whether you’re looking for rapid drainage with scuppers or controlled channeling with gutters, ensure your choice suits your building’s needs and Arizona’s dynamic weather patterns.
