Gutter Installation in Cincinnati: Sizes, Materials, Guards

To choose gutters for a northern Cincinnati home, decide on three things: seamless or sectional, the material, and the size of the gutters and downspouts. Then make sure they are hung with the right slope and support. This guide walks through each choice. If you want a quote, see our gutter installation and repair page.

The Cincinnati area gets about 45 inches of precipitation a year, counting melted snow, based on NOAA's 1991-2020 normals for the Cincinnati airport. Your gutters carry that water away from the foundation, siding, and landscaping. When they fail, you can end up with a wet basement, rotted fascia, and washed-out beds.

Seamless vs. sectional gutters

Sectional gutters come in pre-cut lengths that snap or screw together. Home stores sell them, and many homeowners install them on their own. They cost less up front. Each joint is a place that can loosen and leak over time, so check the joints every season.

Seamless gutters are formed by a machine from a coil of metal and cut to the length of each run. Joints are only at the corners and downspout outlets, so there are fewer places to leak.

Gutter materials compared

Each material has trade-offs. The life spans below come from the InterNACHI life expectancy chart, a home inspector reference. Real life depends on installation and upkeep.

Aluminum is a common choice for homes. Seamless aluminum comes in more than one thickness. Ask for the thickness in writing, because thicker metal resists dents better.

Copper suits older and historic homes where looks matter. It needs a crew that can solder joints.

Steel is strong but must keep its coating intact to resist rust.

Vinyl is the budget option. It comes in sections joined with connectors. Vinyl expands and contracts with temperature, so the maker's instructions plan for it. For example, Amerimax's vinyl gutter instructions have you cut lengths using temperature marks and leave one end free to move. If you are weighing vinyl, ask how the system handles that movement through our winters and summers.

The right size for your roof

Gutter size depends on roof area, roof slope, and how hard it rains, according to Berger's gutter and downspout sizing guide. Berger is a gutter maker, and its guide follows SMACNA sheet metal methods.

Homes usually get 5-inch or 6-inch gutters. A 6-inch gutter carries more water. It is worth a look for a large or steep roof, or where several roof sections drain into one run.

Downspouts matter just as much. Common rectangular sizes are 2x3 inches and 3x4 inches. A bigger gutter with a small downspout still overflows, so size them together.

Gutter guards: worth it or not?

Gutter guards cut down on cleaning. No guard ends maintenance.

• Micro-mesh screens use a fine mesh that keeps out leaves and most smaller debris. Debris can sit on top, so they need an occasional brushing.
• Reverse-curve (helmet) guards use a curved cover that sends water around the edge into the gutter while leaves slide off. In very heavy rain, some water can run past the edge. They also change the look of the roof edge.
• Foam and brush inserts cost the least and are easy to put in. They sit inside the gutter and can hold debris, so they need to be pulled out and cleaned.

If your house sits under mature trees, guards save the most work. On an open lot, they are more of a convenience.

What proper installation looks like

Gutters work only as well as they are hung. Here is what to ask your installer about. The numbers come from Berger's technical guide.

• Slope toward the downspouts. Berger calls for at least 1/16 inch of fall per foot, or about 5/8 inch over 10 feet. Gutters can run level for looks, but then they need more downspouts.
• Hangers into solid wood. Fasteners should reach solid framing behind the fascia, such as the rafter tails, not just a thin trim board. Berger sets hangers no more than 36 inches apart, and 18 inches apart where snow and ice last.
• Position below the roof line. Berger places gutters below the line of the roof so sliding snow and ice clear them.
• Downspouts on long runs. Berger treats 50 feet as the practical limit for one downspout and calls for an expansion joint on longer runs.
• Water carried away. Extensions or underground lines should carry water several feet from the foundation, onto ground that slopes away from the house.
• Sealed corners and end caps. Every joint and corner gets sealed to stop drips.

When to repair vs. replace

Repair makes sense when gutters have isolated leaks, a section has pulled away from the fascia, or a downspout is damaged. Replacement is the better call when gutters sag along several sections, seams fail in several spots, the metal is corroded through, or water is pooling behind the gutters and rotting the fascia.
