Gambrel Roof

A gambrel roof is defined as a symmetrical two-sided roof design with two slopes on each side, where the lower slope is steeper than the upper slope. The gambrel design maximizes interior headroom and usable attic space and is commonly associated with barn-style and Dutch Colonial architecture. Gambrel roofs require more complex framing and additional flashing at the slope transition points, which can increase roof replacement costs by 15% to 25% compared to a standard gable roof.
