Gutter Terms

The fitting that connects the gutter to the downspout, allowing water to transition smoothly between the two.

A curved downspout section that redirects water flow toward the desired discharge point.

Closes off the end of the gutter to prevent leaks and direct water properly to the downspout.

A flexible fitting connecting two gutter sections, allowing them to expand and contract with temperature changes without warping or separating.

A vertical or horizontal board running along the lower edge of the roofline, where gutters are attached.

The horizontal trough installed along the edge of the roof to collect and direct rainwater away from your home or building.

Also known as a “gutter apron,” it’s an L-shaped piece of flashing installed beneath shingles at the eaves. It directs roof runoff into the gutter and prevents leaks behind it. (You can backlink “Eaves” to your roofing glossary.)

A protective cover—usually a metal mesh—installed over gutters to prevent leaves and debris from clogging while maintaining proper water flow.

A drainage system built into a roof membrane that channels water through concealed pipes inside the building. Protects from flooding and structural damage.

A decorative and functional box that collects water from a scupper or box gutter before it enters the downspout.

Angled fitting that connects two gutter sections at a corner, creating a smooth directional transition.

A backup drainage system that handles excess water when standard downspouts are overwhelmed—common in heavy rain or clogs.

An opening through parapet walls on flat or low-slope roofs that directs water away from the structure via internal piping.

The slope or angle of the gutter run that ensures water flows toward the downspout. Typically drops ¼ inch per 10 feet of gutter.

A decorative and functional alternative to a traditional downspout that guides rainwater down in a cascading motion, reducing splashing.

The total horizontal length of the gutter system from one end to another—such as from one downspout to the next.

A drainage outlet that allows water to flow directly through a parapet wall or roof edge (often on flat or low-slope roofs) into a leader head or downspout.

The underside of a roof overhang connecting the fascia to the home’s exterior wall. It aids in attic ventilation and gives a finished appearance.

A sloped block placed beneath the downspout to channel water further away from the home’s foundation, preventing erosion.

Hardware used to attach and support gutters from inside the trough, creating a seamless exterior look. Commonly used in hidden gutter systems for a cleaner appearance.

A durable, rust-resistant metal strap used to secure the downspout (leader pipe) firmly against the exterior wall.

A fast-drying, waterproof, and mold-resistant sealant used to repair leaks at seams, joints, and end caps.

A traditional gutter attachment method. The spike is a long nail driven through the gutter and fascia, while the ferrule is a hollow sleeve that prevents the gutter from crushing when tightened.

Also known as a French drain, this buried pipe system carries water from downspouts away from the foundation. It prevents flooding and preserves curb appeal by keeping the system out of sight.

A strong, weather-resistant material coated with zinc to prevent corrosion. Over time, the coating can wear away, making maintenance important to prevent rust.

An affordable, lightweight option made of PVC (polyvinyl chloride). Rust- and corrosion-resistant, best suited for mild climates.

Factory-cut gutter pieces joined together at seams to create a continuous run. Easy to install but more prone to leaks at the joints.

A single, continuous piece of material custom-cut on-site for your roofline. Eliminates most seams, reducing leak potential and maintenance.
