Abstract:
A shaped roof element (1) for roofs made of elements, the roof element (1) comprising a first and a second side edge (4, 6), an upper edge (8) and a lower edge (10), a profile substantially parallel to the side edges (4, 6) and a series of steps comprising two or more steps (12, 14) extending substantially parallel to the upper and lower edges (8, 10), the steps being produced so that the lower edge (10) forms one of the steps (14). The step (14) on the lower edge (10) is produced in the form of a round bend (20) bending underneath the shaped roof element (1), the profile of the bend corresponding substantially to a profile parallel to the side edges (4, 6) of the shaped roof element (1).
