PROBLEM TO BE SOLVED: To solve the problem of being unable to sufficiently restrain sounding by the expansion of a roof covering material, by using a packing material for fixing the roof covering material in-between by a panel presser, in a vertically laying roof structure arranged so that a side end part of the roof covering material overlaps with an end part of a backing material. SOLUTION: Fine innumerable recess-projection surfaces are arranged in a part for contacting with at least a fixing edge part of the roof covering material or at least a fixing member, and are constituted so as to restrain a generation sound by the expansion of the roof covering material. Here, at least means a partial edge part or the whole surface of the roof covering material. The fine innumerable recess-projection surfaces are desirably arranged on both surfaces by a mode of fixing the roof covering material. COPYRIGHT: (C)2006,JPO&NCIPI
