The gable roof is most commonly identified by which feature?

• A. Two sloped sides.
• B. A flat top.
• C. A curved dome.
• D. A single long slope.

Answer: (A)

A gable roof is defined by two sloping sides that meet at a ridge, creating the triangular end walls called gables. That pair of opposing slopes gives the distinct peaked shape that’s easiest to recognize. Other roof forms don’t have this two-slope, ridge-and-triangular-end configuration: a flat top describes a flat roof, a curved dome is a dome shape with no pitched sides, and a single long slope describes a shed mono-pitched roof.
