These simple but elegant gambrel roof structures have been popular on hay barns for many years. There's no reason, though, why the classic gambrel cannot be used on other kinds of structures (such as log cabins) when storage space is at a premium.

What is a gambrel roof?

A gambrel roof is a symmetrical, two-sided type of roof design featuring two distinct slopes on each side–the upper slope is shallow, while the lower slope is much steeper. This configuration maximizes usable space beneath the roof, making it ideal for attics, lofts, or additional living areas. The gambrel design is a popular choice for square-shaped houses and residential buildings seeking both functionality and visual appeal.

Historically, gambrel roofs have been prominent in Dutch Colonial and Georgian-style architecture, as well as in barn roofs and farmhouses across North America since the 17th century. Their design not only offers increased interior space but also facilitates efficient water drainage due to the steep lower slopes.

The term “gambrel” is believed to derive from the Medieval Latin word “gamba,” meaning horse’s hock or leg, referencing the roof’s bent shape. As one of the more recognizable types of roof lines, the gambrel roof offers a classic design that complements many architectural styles. This roof style remains popular today for its blend of aesthetic appeal and functional benefits.
