What type of roof has four faces resting diagonally between the gables and converging at the top?

• A. Helm Roof
• B. Hip Roof
• C. Gable Roof
• D. Mansard Roof

Answer: (A)

The essential idea is a four-faced roof that forms a compact crown by planes that rise from the walls and meet at a top point, with those planes arranged so they run diagonally between opposite gables. This is the helmet (helm) roof. Its defining look is exactly that: four faces converging to a apex, offering a helmet-like silhouette where each plane sits between the gable ends.

Gable roofs use only two sloping sides to create triangular gables on the ends, so they don’t have four diagonal faces meeting at a top. Mansard roofs on the other hand have two different pitches on each side and produce a double-height, cultivated top rather than a clean four-face crown. Hip roofs also have four faces, but the describing detail—planes resting diagonally between gables and meeting at a single top point—points to the helmet roof’s distinctive diagonally interlocking planes and its helmet-like apex.
