​HIPPED ROOF, the name given in architecture to a roof which slopes down on all four sides instead of terminating on ​two sides against a vertical gable. Sometimes a compromise is made between the two, half the roof being hipped and half resting on the vertical wall; this gives much more room inside the roof, and externally a most picturesque effect, which is one of the great attractions of domestic architecture in the south of England, and is rarely found in other countries.
