Half-Round Gutter

A half-round gutter is a semicircular, tube-like gutter often used on historic or high-end homes. It sheds debris well but holds less water than a K-style gutter of the same width.

Half-round gutters have a classic, smooth U-shaped profile that suits older, historic, and architecturally traditional homes, and they're frequently chosen in copper for a premium look. Their rounded interior is easy to clean and resists buildup, but they carry less water than K-style for a given width, so sizing and downspout placement matter. They typically cost more to fabricate and hang than K-style. For homeowners prioritizing appearance and longevity — particularly in copper — half-round is a strong, lasting choice.
