Origins of Gambrel Roof Designs
Gambrel has Latin origins where the word ‘ gamba’ refers to the leg or hock or a horse. It also has an American and European origin which basically refers to a curb roof.
Despite the distinction, Europeans had a hard time differentiating mansard and gambrel roofs and collectively used the same term for all of them. Today, there are a few variations of gambrel roofs such as Dutch, Dutch Colonial, Swedish, German- English, New England or French gambrel roofs. Besides gambrel and mansard roofs being similar, they have different cross-sections. For instance, for the gambrel, there is a vertical gable rather than one that’s hipped at 4 corners like the mansard. Also, unlike the mansard, the gambrel roof overhangs at the facade.
As for North America, the origins of gambrel roof designs are unknown. In America, the oldest design was built in Harvard University as far back as 1677. Peter Tufts House circa 1677 to 1678 is the oldest house in the U.S with a gambrel roof. The Fairbanks house, the oldest framed house surviving today also has a gambrel roof but this was added later.
There are a few claims to the origins of gambrel roofs in America. First, there were Dutch, Spanish, English and Portuguese traders and mariners that settled in Southeast Asia (Indonesia) before settling in Europe and later America. When in Indonesia, they encountered homes built with roof designs where there was a hip at the beginning and ended with a gable found on the ridge. The gable found at the end was simply acting like a chimney to dissipate smoke from any fires lit inside for cooking purposes.
Evidently, these designs were brought back to Europe and America and introduced by local builders. There are different parts of the world that still use this roof design up to date. Secondly, there are gambrel designs originally found in Netherlands that were brought back to America by seamen. Lastly, these roof designs were introduced for reasons such as allowing wide buildings, using short rafters or as a way to evade paying taxes.
