PROBLEM TO BE SOLVED: To provide a roof structure capable of enhancing air permeability between a roofing board and each roofing material.SOLUTION: The roof structure includes uneven roofing materials 18 each having protruded parts 19 opened downward and protruded upward and recessed parts 20 opened upward and recessed downward, formed alternately in a direction along an eaves, the uneven roofing materials 18 being provided on a roofing board 5 where ventilation spaces 24 are formed between each of the protruded parts 19 and the roofing board 5, the uneven roofing materials 18 having extended margin parts 25, respectively, protruded to the further outdoor side than the eaves side edge of the roofing board 5 in an eaves ridge direction so that outside air is introduced from the extended margin parts 25 inside introduction parts 26 constituted by the protruded parts 19 into the ventilation spaces 24. Herein, an eaves gutter 40 is provided along a fascia board 3 at the eaves end where the extended margin parts 25 are provided. A suction gap 47 is formed between an indoor side wall part 44 of the eaves gutter 40 and the fascia board 3. The face on the indoor side of the eaves gutter 40 at the upper end of the indoor side wall part 44 is a straightening face part 48 which is gradually farther from the fascia board 3 as extending upward. |
