A gambrel roof is a type of roof design characterized by two slopes on each side. The lower slope is steeper, while the upper slope is more gentle. This design allows for more headroom and usable space in the attic, making it popular in barn and farmhouse architecture. Gambrel roofs are often associated with Dutch Colonial and American Colonial styles. They are commonly seen in rural areas and are effective for shedding rain and snow. The shape also provides a distinctive aesthetic, contributing to the charm of traditional buildings.
