PROBLEM TO BE SOLVED: To provide roof structure for a building structure executable without hindrance even when the working width of lower roofing is different from that of upper roofing, and securing large sectional strength without using a member such as a tight frame, by interposing a plate body between the lower roofing and upper roofing, and integrating them. SOLUTION: This roof structure for the building structure has the lower roofing 10 formed by molding a metal plate in the alternate corrugated shape of crest parts 11 and trough parts 12; the plate body 20 mainly composed of an inorganic material; and the upper roofing 30 provided with seam parts 31, 32 at both side edge parts of a metal plate of plate shape. The lower roofing 10 is installed placing the longitudinal direction orthogonally to the drainage pitch of the roof of the building structure, and the adjacent lower roofing 10 are connected to each other at the trough part 12 to constitute a floor slab. The plate body 20 is installed on the floor slab, and the upper roofing 30 is installed on the plate body 20, placing the longitudinal direction parallel with the drainage pitch of the roof. The adjacent upper roofing 30 are jointed to each other by the seam parts 31, 32.
