A Hip Roof (or Hipped Roof) features slopes on all four sides of a building, meaning that there are no gable end walls.
If a building has a square floor plan, then a hip roof will take the form of a pyramid, rising to a central point. If a building has a rectangular floor plan, then a hip roof will rise to a ridge running along the longer axis of the building. Hip roofs are particularly suitable for buildings with irregular floor plans.
As they have no gable ends, hip roofs are considered less prone to damage caused by strong winds. Another advantage is that they do not require any external timber work (such as Bargeboards) above the height of the Eaves, so less maintenance is required.
Hipped roofs are more complicated and expensive to construct than gabled roofs. The roof trusses generally have to be constructed on site, rather than being prefabricated.
Hipped roofs usually slope evenly on all sides (unlike mansard roofs where each segment of the roof has two slopes, one shallow at the top and one steep on the lower part).
