  Thereafter, as shown in FIG. 1 (g), the claws 15 inserted through the holes 431 of the mounting member 3B are in a state 15 ′ ′ in which they are turned down as indicated by hatched hatching arrows. On the other hand, a state shown in FIG. 1 (h) in which the roof material 2 and the crosspiece cover 3 (attachment member 3B) are integrally fixed is obtained.

In the crosspiece cover 4 for eaves most arranged under the water side, there is no need to integrate the decorative member 4A for eaves and the attachment member 4B for eaves in advance, and as shown in FIG. After attaching only the member 4B so as to cover the side edges of the support member 1 and the roof material 2, the evanescent decorative member 4A may be attached.
The attachment of the eaves attachment member 4B at that time is the same as the attachment of the ordinary cross-piece cover 3 (attachment member 3B) in the third step. Moreover, about attachment of the cosmetic member 4A for eaves-ends, it is the same as that of attachment of the normal cosmetic member 3A in the integration process of the said cross-piece cover 3. FIG.

  Although the roof of the building of the present invention thus constructed is finally in the state shown in FIG. 1 (h) and FIG. 4, the deformation of the decorative member 3A integrally attached to the inner surface side of the crosspiece cover 3 Since the attachment member 3B for preventing the frame plays a role of firmly attaching the crosspiece cover 3 to the support member 1, there is no need for a separate member, and the number of parts to be used is small. The crosspiece cover 3 can be attached easily and firmly. Therefore, the roof of a large building or a residential building can be easily installed without using nails and the like.

Further, in the first embodiment, the support member 1 has the claw piece 15 rising upward, and the holes 221 and 341 provided in the roof material 2 or the attachment member 3B are inserted through the claw piece 15.
