Further, in the roofing material 5 for thatching of the present invention, since the base member 6 is superposed on the entire surface of the plate portion 2, the sound insulating effect is high, and the sound of rain and wind is sufficiently shielded to keep the room quiet. is there.

<Effects of the Invention> In short, the present invention forms a lower bent portion that bends downward at the front edge of the plate portion and an upper bent portion that bends upward at the rear edge of the plate portion, and A laterally long roofing roof material in which a hard base material is positioned in a superposed manner on the lower surface and the front edge is positioned inside the lower bent portion and the rear edge is exposed to the upper bent portion. The lower bent portion has a U-shaped cross section, and the lower bent portion has a stepped portion formed by a rising piece and an upper piece, and the upper bent portion has a rear edge of the plate portion. Is provided by bending upward to provide a rising portion, and a mounting portion in which an upper end of the rising portion is bent backward, a standing portion in which a rear end of the mounting portion is bent upward, and a rising portion of the standing portion. A step portion that receives the stepped portion of the lower bent portion is formed by the support portion whose upper end is bent rearward, and the rear end of the support portion is formed. A mountain-shaped portion that forms a locking space in which the front surface is opened by bending the roof in a folded shape, and the lower bending portion of the roof material located above is locked to the upper bending portion of the roof material located below Then, the stepped portion of the lower bent portion is received by the stepped portion of the upper bent portion, and a space is formed on the front side of the rising portion.

Therefore, in particular, since the stepped portion of the lower bent portion is received by the stepped portion of the upper bent portion, the connection strength between the upper bent portion and the lower bent portion of the upper and lower roofing materials remarkably increases, and snow is accumulated on the connected portion. This connection will not be crushed or damaged even if a large load is applied by a worker. Even if a negative pressure is generated on the leeward roof surface during strong winds, the substantial wall thickness of the roof material does not cause pulsation in the roof material, and rainwater is not sucked in by the dropper action due to pulsation. The rain is good. Even if condensed water is generated on the lower surface of the plate portion, this condensed water flows down from between the plate portion and the hard base member to the front edge of the base member and is transmitted from the front edge of the base member to the front hanging portion. Flow into the inside of the lower bent portion, flow laterally inside the lower bent portion, and drain from the surface of the roofing material on the eaves side. It does not run down to corrode the base or stain the ceiling. Further, in the present invention, since the hard base member is superposed on the substantially entire surface of the plate portion, the sound insulation effect such as rain noise and wind noise is high.
