Abstract: A roof panel is furnished with a flat covering element (1) having a front edge, a rear edge, a first side and a second side, a projecting bent-up side face (2) vertically protruding from the flat covering element (1) near the first side, and a bent-up side face (4) vertically bending off at the second side of the flat covering element (1). An inwardly flanged edge (3) is formed at the projecting bent-up side face (2) bent over toward the inside. An outwardly crimped edge (5) is formed at the bent-up side face (4) bent over toward the outside. A single piece connected attachment edge (7) for screw holes is disposed along the projecting bent-up side face at the outer side of the projecting bent-up side face. An upwardly warped reinforcement bead (8) is extending parallel to the first side and to the second side and subdividing the flat covering element (1).
