PROBLEM TO BE SOLVED: To provide a roof waterproof repairing method which prevents formation of a dip in an upper surface of a joint portion, ensures the flatness of an uppermost waterproof material layer (6), and prevents deposition of dust on a surface of a new waterproof material layer, even if an expansion joint (3) between protective concrete (2) mounted on an asphalt waterproof layer (4) on a surface of skeletal concrete (5), and the other protective concrete (2) adjacent to the same, is deformed due to expansion/contraction caused by temperature variation etc.;SOLUTION: According to the roof waterproof repairing method, an expansion joint covering composite sheet (1) formed of a steel plate (11) thin and excellent in corrosion resistance, and a tacky material layer (12) laminated on a rear surface of the same, is laid in the vicinity of an upper surface of the expansion joint (3), and the waterproof material layer (6) is overall arranged on all of an upper surface of the expansion joint covering composite sheet (1) and an upper surface of the exposed protective concrete (2).;COPYRIGHT: (C)2008,JPO&INPIT
