The half-round gutters often referred to as “half-rounds,” have the appearance of a circle that has been cut in half. The backs of half-round gutters can either be straight or semi-circular. Due to their clean look and smooth geometry matching modern architecture, this type works well for contemporary homes that are looking for a cleaner and smoother aesthetic.

Besides being decoratively pleasing, half-round gutters offer superior water carrying capacity due to their larger diameter, although square line gutters can hold a higher volume of water. Due to their smooth, rounded shape, they require less maintenance as well. As a result, there is a lower likelihood of debris blocking the flow of water. Moreover, these units are much more effective at flushing out debris during light rain than square gutters.
