Which roof type is noted for having steeply pitched sides while maintaining a broad, flat top?

The mansard roof is distinguished by its unique design that features steeply pitched sides and a broad, flat top. This architectural style originated in France and is often associated with the Second Empire style of architecture, which became popular in the 19th century. The steep pitch allows for additional living space in the attic or upper floors, making it an attractive choice for homeowners who want to maximize their usable area without expanding the footprint of the building.

In contrast, other types of roofs have different characteristics. The gambrel roof, for example, has two slopes on each side but lacks the flat top that defines a mansard roof. A hip roof typically has slopes on all four sides, forming a more pyramid-like shape rather than featuring the flat peak. The gable roof features two sloping sides that meet at a ridge, creating a triangular shape, but also does not contain a flat surface at the top. Understanding these specific features helps in recognizing the unique qualities of the mansard roof among the various roof types.
