The present invention relates to a fabric for a roofing sheet for waterproofing a roof of structure. Warps and wefts, at least with the numbers and lengths corresponding to an area of the fabric, are arranged to overlap each other forwardly and backwardly. While binding one side warp and another side warp are alternately wound in a zigzag shape, a top side loop and a bottom side loop are formed to be alternately interlaced at each overlapping part between low melting finishing fibers, or between a ground fiber and a finishing fiber which cross wefts. Finishing fibers are arranged at both side surrounding parts of the fabric, and ground fibers are arranged between the finishing fibers of both side surrounding parts. By fusing the finishing fibers with ultrasonic waves, the warps and wefts are grafted and fixed. Also, unnecessary warps, wefts, and ground fibers are cut on the basis of the fused finishing fibers.
