The side edges of the upper inner layer material 21 made of wood wool board or the like are supported on the steps 19a of the rafters 19 and fixed by appropriate means, and the upper inner layer material 21 is laid between the rafters 19, and the lower inner layer material 12 and An air layer 22 is formed between the upper inner layer material 21 and the upper inner layer material 21 . A roof plate 23 made of a long galvanized steel plate, a painted steel plate, or other metal plate is horizontally covered on the upper inner layer material 21, and the roof plate 23 is attached to the rafters 19.
It is supported above and fixed by a cut-and-raised piece 19d formed on the upper surface of the rafter 19, and the opposing ends of the roof plates 23 adjacent in the direction of the eaves are engaged.

A snow stopper member 24 made of an angle or the like is fixed parallel to the main house 11 by an appropriate means to a portion of the roof plate 23 near the eaves, that is, the second or third roof plate 23 from the eaves side. An eaves member 25 is fixed to the eave side ends of the roof plates 23 and 19 at the eaves side end, and the eave side end of the water leak prevention plate 14 at the eave side end is brought into contact with this member.
