Half Round Gutters: An Overview

Half Round Gutters: An Overview

Half-round gutters resemble a tube that’s cut into half. They have a symmetrical U-shape, making them more challenging for DIY installation. Half-round gutters attach to your roof’s fascia. Most have a beaded profile on the front side as a decorative element.

Size and Water Capacity

Half-round gutters come in widths ranging from 4” to 8” inches. 6-inch wide half-round gutters are the most common. They handle heavy rainfall and snowy climates.

Most homes in mild climates may only need 5-inch half-round gutters. If your roof is under 2,500 square feet, 5-inch wide gutters will suffice. Homeowners in areas prone to heavy rainfall should consider 8-inch gutters.

Cost Per Linear Foot

The cost of installing half-round gutters varies since they’re available in different materials. Aluminum gutters are cheaper than galvanized steel, while copper gutters are high-end. Installation costs range from $9 to $17 per linear foot, with a national average of $13.

These figures don’t include the cost of accessories like downspouts, elbows, and hangers. Labor and your roof’s pitch are other cost factors. Installing gutters on single-story homes with flat roofs is more DIY-friendly than on double-story ones. Hiring a licensed contractor affects the final cost but is worth it.


The longevity of half-round gutters depends on the material. Both aluminum and galvanized steel gutters can last between 20 to 30 years. Copper half-round gutters last up to 50 years. Steel gutters are ideal for homes in areas with extreme weather fluctuations.

Why Choose Half-Round Gutters for Your Home?

The inside part of half-round gutters is smoother than k-style gutters. It boosts the gutters’ longevity by preventing corrosion. The smooth surface allows for easy cleaning.

Seamless half-round gutters also don’t leak as often as sectional models. Unlike k-style gutters, they have fewer areas where debris may accumulate.

If you’re living in a historic home, choose half-round gutters. They complement most traditional roof designs. Half-round copper gutters form a patina as they age, making them appealing to most homeowners.

Half-Round vs. K-Style Gutters

Half-Round vs. K-Style Gutters

K-style gutters hold more water compared to half-round gutters. Their shape makes them less prone to bending or warping during extreme temperatures.

Unlike half-round gutters, k-style models are easier to install DIY. Half-round gutters are ideal for homes built before the 50s with metal roofs. You need to hire a professional because they require more brackets during installation.

Since half-round gutters don’t lay flat on the roof’s edge, they might need pricier brackets. They’re also easier to unclog since they have fewer hangers.

Because of their shape, half-gutters don’t hold standing water. It makes them less prone to corrosion. K-style gutters come in pre-cut sizes and seamless options. They’re ideal for homes with angular roofs.

Round vs. Square Gutters

Round gutters are more effective in keeping rainwater flowing. They’re easier to clean than square gutters and complement your roof’s shape.

Square gutters cover the ends of most roof designs, giving your home a neat look. Round gutters are pricier and more challenging to install than square gutters.

Since square gutters have wider dimensions, they channel more rainwater. Square gutters are ideal for large residential and commercial buildings. Choose square gutters if you live in an area with constant rainy weather.

How to Install Half-Round Gutters

How to Install Half-Round Gutters

First, get the necessary supplies and determine the number of gutters your roof needs. If you’re opting to DIY the installation, these steps would be helpful:

Step 1: Adjust the Pitch

Setting the right pitch holds your half-round gutters in place. Determine the highest point of the gutter’s runoff. Use a pencil to mark areas for screwing the brackets. Place a bracket and a gutter section against the fascia to make the marks. Using a water level, align the mark with the downspout’s end.

Step 2: Install the Gutter Hangers

Install the gutters hangers 36 inches apart for extra support. They should be closer if you live in an area with snowy weather. Make the hangers wider if you’re installing them on an angled fascia.

Step 3: Drill Downspout Holes

Measure from the end of the roof to above where each downspout connects. Make holes on the downspout with metal shears to secure the brackets. Measure the bracket’s size before cutting the downspout holes.

Step 4: Hang the Sections

Place the back of your half-round gutters to the brackets. Don’t fasten the brackets before sorting the sections.

Step 5: Join the Gutter Sections

Use slip-joint connectors to attach the sections if you install aluminum half-round gutters. Pop rivets and aluminum gutter cement also help seal the sections. For steel and copper half-round gutters, soldering is the most viable option.

Step 6: Weld the Seams

Welding the seams helps prevent leaks. Using a soldering iron to weld the seams and end caps would suffice. You’ll need weld fluxes when heating steel gutter seams to control the molten metal. To remove bubbles, use an emery cloth to polish the heated seam.

Step 7: Install the Downspout & Elbows

Drill the brackets to hold the downspout pieces in place. Position the downspout in the direction of the underground rainwater system. Attach the elbows facing away from your basement to prevent flooding. Drill brackets to secure the downspout.

The Perks of Half-Round Gutters
