The hip roof also slopes from all four walls toward the center, but not so steeply as does the mansard roof. It is usually brought to a point or a ridge at the top, as in Fig. 166, but sometimes it is finished with a small flat deck, as in Fig. 167. The hip roof as a rule allows of very little useful space in the attic, and if this type of roof is employed it is usually done with the idea of sacrificing the attic space and doing without the rooms under the roof for the sake of the exterior appearance.
