PROBLEM TO BE SOLVED: To provide an end structure of a repair roof material used in a waveform slate roof repair construction method, capable of smoothly performing screwing working of a screw bolt. SOLUTION: Trapezoidal fitting crest parts 2a, 2b overlapped horizontally between adjacent repair roof materials 1, 1 are formed on both right and left sides of the repair roof material 1 respectively, a bending ridge edge 9, contacting on an inclination face 21 of a waveform crest part 7a of an existing waveform slate plate 5 and an extension end edge 10 which extends outward from the bending ridge edge 9 by substantially horizontally bending the skirt outer end of one lower side overlapped fitting crest part 2a, and position holding action of a ceiling wall 11a of the fitting crest part 2a is produced by the bending ridge edge 9.
