To eliminate the portion of a bolt body projected from a nut via a simple method after a mounting work.
Regarding a mounting method for a roof material, an engagement part 31 formed on the end of a bolt body 33 is coupled to the engaged part 21 of a roof structural body 2. Also, the other end of the bolt body 33 is passed through a roof material 1 and a nut is screwed to a threaded part 32 formed thereon. Then, the roof material 1 is mounted on the roof structural body 2 via a cushion material and a washer. In this case, a shrunk part A smaller than the diameter of the bottom of the threaded part 32 on the end of the bolt body 33 is preliminarily set, so as to be positioned above the nut. Thereafter, the end of the bolt body 33 is removed from the shrunk part A, after the nut is screwed thereto.
