As shown in FIG. 5, the sheet-like substrate 7 is formed by a roll forming method.
And papers 8 and 9 are integrated by pressure. That is, a cylindrical first roll 13a and a second roll 13b having a large number of concave dies 14 for forming the non-slip protrusions 10 formed on the cylindrical surface are opposed to each other with a predetermined gap. The first and second rolls 13a and 13b are fed into the gap between the first and second rolls 13a and 13b while the flexible synthetic resin 7 'and papers 8 and 9 serving as the raw materials of the sheet-like base material 7 are supplied. Roll 1
3a and 13b are rotated in the directions of arrows A and B, respectively.
Then, the rotation of the first and second rolls 13a and 13b causes the sheet-like base material 7 and the papers 8 and 9 to rotate as shown in FIG.
Are pressed and integrated, and the non-slip protruding portion 10 is formed by the concave mold 14, and the roof base material 6 is continuously formed and discharged in the direction of arrow C. At this time, as shown in FIG. 2, the paper 8 on the upper surface side is often broken by the upper small-diameter projection 12 of the non-slip projection 10 to form a hole.
There is no problem because the peripheral portion is crimped and integrated with the side surface of the lower large-diameter projection 11 or the like.

Hit 4, with nails. At this time, the worker rides on the upper surface of the roof base material 6 with the work shoes, but as shown in FIG. 2, a large number of slips protruding at a predetermined height on the upper surface of the sheet-like base material 7 in two stages. The stopper projections 10, 10,... Have the effect of preventing the feet from slipping. That is, the upper small-diameter projection 12 of the non-slip projection 10 is in a state where it is hard to make the shoe sole made of rubber or the like, so that the tile bar 4 can be safely hit with little slip on the roof base material 6. Further, the roof tile 4 is provided with a non-slip projection 1 as shown in FIG.

Roofing is performed on the upper surface of the roof base material laid on the ground board by a large number of non-slip protrusions integrally formed by projecting in two steps on the upper surface of the sheet-like base material at a predetermined height. It exerts the effect of preventing the worker's feet from slipping. At this time, the stability of the feeling of stepping is maintained by the large-diameter projection at the lower part of the anti-skid projection, and the upper small-diameter projection is hardly attached to the lower surface of the work shoes of the worker, so that the anti-slipping effect can be increased. Therefore, the worker can improve the work safety with almost no sliding on the roof base material. In addition, since the plurality of slip prevention protrusions are arranged so as to be present in a predetermined unit area, a plurality of roof tiles having a predetermined width to be struck on the upper surface of the roof base material are provided with a plurality of slips in the width direction. Since it is supported by the stop projection, the tile roof in the struck state can be stably fixed so as not to wobble in the width direction.

Can be formed to form means for ventilation and drainage. Therefore, it is possible to allow the water leaking from the roof tile to pass through the eaves direction while staying in the upper corner of the roof tile, thereby improving the drainage property and the air permeability, thereby preventing the roof tile from being corroded by moisture. Can be.
