The prior art shown in FIG. 10 requires that the new roof be fixed at the hook bolt positions on the existing roof. Therefore, it was necessary to prepare a new roof according to the mounting dimensions of the existing roof. For example, if the spacing between adjacent hook bolts in the girder direction of the roof does not match the dimensions of the new roof, it has been necessary to drill holes in the existing roof at peaks where there are no hook bolts. In addition, if the separation distance between the hook bolts on the existing roof is large in the girder direction of the roof, there is a possibility that the new roof will sink.

The present application is a structure in which a corrugated metal roofing material is mounted on a corrugated slate roof. Fixtures are attached to the hook bolts that secure the corrugated slate roof. The secondary fixture has a top surface and support legs extending outwardly and downwardly from opposite ends of the top surface. The upper surface of the auxiliary fixture is placed on the peaks of the corrugated slate roof, and the lower ends of the support legs are placed on the valleys of the corrugated slate roof. A corrugated metal roofing material is fixed on the fixtures and on the auxiliary fixtures with fasteners.

In addition to the corrugated metal roofing being secured to the fixtures at the hook bolt locations on the corrugated slate roof, the present application also secures the corrugated metal roofing to secondary fixtures at the hook bolt free locations. Therefore, for example, even if the spacing between adjacent hook bolts in the girder direction of the roof does not match the dimensions of the corrugated metal roof material, auxiliary fixtures are placed and used on peaks where there are no hook bolts. No need to drill holes in the corrugated slate roof. In addition, even if the separation distance between the hook bolts on the corrugated slate roof is large in the girder direction of the roof, the corrugated metal roof material is supported by the auxiliary fixtures, so sinking is less likely to occur.

In the corrugated slate roof S of this embodiment, a roof material having peaks S1 and valleys S2 is fixed to the roof base using hook bolts F. As shown in FIG. The hook bolt F protrudes from the crest S1 of the corrugated slate roof S toward the surface side. The hook bolts F do not protrude from all peaks S1 of the corrugated slate roof S. Therefore, there is also a mountain portion S1 where the hook bolt F does not protrude.

The corrugated metal roofing material N of this embodiment is a roofing material in which peaks N1 and valleys N2 are formed. The formation pitch of the peaks N1 and valleys N2 of the corrugated metal roof material N of this embodiment is preferably the same as the pitch of formation of the peaks S1 and valleys S2 of the corrugated slate roof S.
