PROBLEM TO BE SOLVED: To provide a roof structure capable of suppressing aged deterioration of a roof by wind and rain and improving the force of water of rainwater flowing in the roof structure.SOLUTION: A trough material 20 comprises: a roof side face part 21 fixed to an outer peripheral end surface 4 of a roof 1; an outer side face part 22 arranged in parallel with and outside apart from the roof side face part 21; and a bottom surface part 23 laid between the lower ends of the roof side face part 21 and the outer side face part 22. An angle A of the outer side face part 22 with respect to a first bottom surface part 23a of the bottom surface part 23 is set to a roof gradient plus 90 degrees. Thereby, the first bottom surface part 23a of the trough material 20 on a verge side end surface 4b side is obliquely arranged so as to rise toward the outer side face part 22, when the first bottom surface part 23a of the trough material 20 on the eaves edge side end surface 4a side is horizontally arranged. |
