Leader Heads

Leader heads, also known as conductor heads or collector boxes, are an important yet often overlooked component of a building’s rainwater drainage system. Positioned at the top of a downspout, leader heads collect water from the gutter or scupper and guide it into the downspout, helping manage the flow of rainwater efficiently and safely.

What Do Leader Heads Do?

Leader heads serve several key functions:

• Improve water flow: By increasing air circulation and relieving back pressure, leader heads allow rainwater to move more quickly and smoothly through the downspout system.
• Prevent overflow and flooding: During heavy rains, gutters can quickly fill up. Leader heads provide an intermediate catch basin that helps prevent water from backing up and spilling over the edges.
• Reduce noise and splashing: Because they help regulate the flow of water, this also minimizes the noise and mess often caused by fast-moving runoff entering downspouts directly.

Architectural and Design Benefits

Did you know these products also serve a decorative purpose? Available in a variety of styles, materials, and finishes—from copper and aluminum to painted steel—they can complement the exterior aesthetics of both traditional and modern buildings.

In historic architecture, they’re often used as ornamental features, sometimes bearing dates, initials, or custom designs.

Where Are Leader Heads Used?

This key gutter accessory is commonly found on larger or more complex roof systems, commercial buildings, and structures with flat roofs or parapets. They are especially useful in areas with high rainfall or where roof drainage must be closely managed to protect walls, landscaping, and foundations.

Key Considerations

When selecting a leader head, it’s important to match the size and shape to the capacity of the gutter and downspout system. Improper sizing can lead to ineffective drainage.

Additionally, ensuring the material is compatible with the rest of the gutter system helps prevent corrosion and prolongs the lifespan of the components.
