Disclosed is a method and an apparatus for forming metal panel roof tiles having the shape of both male and female roof tiles, which have improved strength and which look like traditional Korean roof tiles. The method includes the steps of passing a metal panel between shaping rolls of a roll forming machine to form a number of crests and troughs in the longitudinal direction of the metal panel; forming small troughs of a corrugated shape in the transverse direction of the metal panel; forming protruding patterns and stepped portions on the crests and troughs of the metal panel by press pressing operation so that the small troughs of a corrugated shape created in the preceding step are spread to form the protruding patterns and the stepped portions; and cutting the metal panel into a necessary length by a cutting device.
