Which roof type typically features outward slopes on all sides with a peak at the top?

The hip roof is characterized by slopes that decline from all sides toward the walls, culminating in a peak at the top. This design creates a more aerodynamic shape that is particularly effective at shedding water and snow, making it suitable for various weather conditions, especially in areas that experience heavy snowfall or rainfall.

Each side of a hip roof is slanted, which contributes to the roof's stability and durability. Additionally, the nature of this roof type helps provide a more finished aesthetic appearance compared to other roof styles, as it does not have the vertical ends typical of gable roofs. The enclosed nature of a hip roof also allows for better ventilation and potentially more usable attic space.

On the other hand, gable roofs feature two sloping sides but do not slope outwards on all sides; instead, they have vertical ends at the gable. Flat roofs are, as the name suggests, flat without a peak, while single pitch roofs have only a single slope, making them different in design and function from hip roofs. Therefore, the defining characteristics of a hip roof align perfectly with the description provided in the question, confirming its suitability as the correct answer.
