PROBLEM TO BE SOLVED: To provide a simple and strong structure of a hip roof for a prefabricated storage, which facilitates assembly operations. SOLUTION: In the structure of the hip roof, paired front and rear rafters coupled in a chevron shape by a rafter coupling fitting are disposed right and left on eaves framed before, behind, right and left, central parts are coupled together by a ridge beam, and the right and left rafters are connected together. An inserting pawl is formed at the end of the rafter. The rafter is screwed into a rafter supporting edge inside the eaves after being temporarily fixed to the eaves by inserting the inserting pawl into an opening provided in an outside rising part of the eaves. Hook parts, formed at the upper ends of corner rafters at four corners, are mounted by being hooked on a butt part between the front and rear rafters. The corner rafter is taken as a shape wherein a channel bar bent along a longitudinal direction is integrated with both vertical walls of the channel bar, which are made symmetrical to the bent channel bar, and provided with a function of making stormwater getting in from the right and left ends of a shingle discharged into a eaves gutter.
