A roof with a double pitch on all four sides is known as what type of roof?

1. Gambrel roof

2. Cape roof

3. Mansard roof

4. Hip roof

The correct answer is: Mansard roof

A roof with a double pitch on all four sides is known as a mansard roof. This architectural style features a dual slope on each side, where the lower part of the roof has a steeper incline, while the upper part has a gentler slope. This design allows for optimal use of space in the upper levels of the building, often creating additional living or storage space in the attic or loft area. The distinctive features of a mansard roof also contribute to its aesthetic appeal and facilitate the addition of windows in the roofline, enhancing natural light. Its historical significance can often be seen in French architecture, particularly from the Second Empire style, which made the mansard roof popular during the 19th century. Other types of roofs mentioned may have unique characteristics but do not conform to the definition provided in the question. A gambrel roof typically has a two-sided roof with two slopes on each side, primarily found in barn architecture. A cape roof is similar to a gable but does not have the double pitch characteristic. A hip roof slopes downwards from all sides, but again, does not feature the double pitch characteristic that is definitive of a mansard roof.
