Which component of a hipped roof distinguishes it from other roof types?

The component that distinguishes a hipped roof from other roof types is the hip. A hip is the external angle formed at the junction of two sides of a roof, specifically where the sloping sides meet. In a hipped roof, all sides slope downwards to the walls, creating a distinct shape that is consistent with the overall design. This unique characteristic provides enhanced structural stability and effective water drainage compared to roofs with a gable design, where only two sides slope downwards.

The other components listed—ridge, eave, and rake—are found in various roof types but do not specifically define the hipped roof design. The ridge is the top horizontal line where two roof slopes meet but is not exclusive to hipped roofs, as it can also be found in gabled roofs. The eave refers to the lower edge of the roof that protrudes beyond the walls, providing drainage and protection. The rake is the edge of a sloped roof that runs from the ridge to the bottom of the roof slope, commonly associated with gable roofs. Therefore, the hip is the defining feature of a hipped roof, setting it apart from those other roof types.
