PROBLEM TO BE SOLVED: To provide a roof structure which is easy in construction since the structure can easily perform the positioning of roof materials, hardly causes the positional displacement of the roof materials, is stable in a laying state, and high in heat insulation property.SOLUTION: A plurality of roof materials 1 are laid on a roof substrate 30 along an eaves ridge direction while partially being overlapped with one another. A plurality of heat insulation substrate materials 2 are interposed between a plurality of the roof materials 1 and the roof substrate 30. Apex faces 24 of the heat insulation substrate materials 1 are formed as support faces 25 on which the roof materials 1 are partially placed. At a plurality of the heat insulation substrate materials 2, eaves-side end faces 28 are formed along the eaves ridge direction while being oriented toward an eaves side of a roof. At eaves-side end faces 29 of the heat insulation materials 2, there are formed contacting parts 4 contacting with the eaves-side end faces 28 of the heat insulation substrate materials 2 which are arranged at eaves sides of the heat insulation substrate materials 2, and position parts 5 not contacting therewith. In the roof materials 1, eaves-side tips of the roof materials 1 abut on the positioning parts 5, and eave-side ends of the roof materials 1 are laid on the support faces 25. |
