Hip roof. A hip roof, hip-roof or hipped roof, is a type of roof where all sides slope downwards to the walls, usually with a fairly gentle slope. Thus it is a house with no gables or other vertical sides to the roof. A square hip roof is shaped like a pyramid.
Hip and pyramid roofs: as the name suggests, a pyramid roof is a roof in the shape of a pyramid and is designed for a square building. A hip roof uses the same basic shape, but is elongated and is designed for a rectangular building. The hip roof is also very popular in North America. Gambrel roof: this is also known as the barn roof, as this style is often used on barns. This roof style maximizes the amount of usable space in the attic or top floor.
