Which roof type is defined by two slopes on opposite sides creating a barn-like appearance and is common on rural buildings?

• A. Gable
• B. Sawtooth
• C. Arch
• D. Gambrel

Answer: (D)

A gambrel roof is defined by two different pitches on each side of the ridge, producing a broad, barn-like silhouette. One side has a shallow upper slope and a steeper lower slope, and this two-stage pitch on both sides gives that distinctive wide, flat-topped look often seen on rural barns. This specific double-pitch profile is what sets it apart from other roof types.

A gable roof has two simple slopes meeting at a ridge and an exposed gable end, which creates a triangular shape rather than the broad barn profile. A sawtooth roof shows a series of small, vertical-to-sloped sections, common in industrial buildings. An arch roof is curved, with no distinct pair of planar slopes.
