To provide a folded-plate roof material capable of preventing water leakage by a simple structure.

This folded-plate roof material 7 is formed by applying end close processing to one end side by forming bottom plates 8a, 8b, a rake side crown-shaped part 10 and a cover side crown-shaped part 11 by bending a plate material in a recess-projection shape. A folded part 14 is formed in the flowing direction in an end close processing part in the end close processing, and the end close processing part forms a flat edge 13, and the edge 13 is bent in the direction for crossing with the folded up part 14 so that the folded part 14 is press-fitted.
