Which type of roof features two slopes on each side, meeting at a central ridge?

The correct answer describes a roof characterized by two slopes on each side that converge at a central ridge. This design creates a triangular shape at either end of the building and provides effective drainage due to the sloped surfaces. A hip roof features slopes on all sides, leading to a common peak or ridge at the center.

The significance of this design lies in its structural stability and the way it deflects wind, making it a popular choice in various architectural styles, especially in areas prone to heavy winds or snow. It also allows for additional living space in the roof (like an attic), while being aesthetically versatile.

In contrast, other roof types do not match this description. A gable roof consists of two sloping sides but does not have slopes meeting at a central ridge—rather, the gable ends are the triangular sections created by the roof's sloping surfaces. A flat roof, as the name suggests, has no slopes, while a single pitch roof features only one sloping side rather than the two necessary for a hip roof.
