Roof covering element, modular roofing sheet

A roof covering element (1) formed as a modular roofing sheet (20), made of a plate material (21), comprising a first side edge (22) and second side edge (23), an upper edge (24) and a lower edge (25), having a series of multiple modules (26) substantially parallel to the side edges forming at least one surface, comprising walls (5, 6, 7) parallel to the upper edge (24) and lower edge (25), wherein:

• between an upper wall (5) and an ending surface (4) of the roof covering element (1) there is an upper crease (8) forming an obtuse angle with the upper wall (5) and an obtuse angle with the ending surface (4) of the roof covering element (1), wherein both of the obtuse angles have an interior beneath the roof covering element (1) and wherein the interiors partially overlap;
• between a central wall (6) and an upper surface (3) there is a central crease (9) forming an obtuse angle with the central wall (6) and an obtuse angle with the upper surface (3), wherein both of the obtuse angles have an interior beneath the roof covering element (1) and wherein the interiors partially overlap;
• between a lower wall (7) and an extreme lower surface (2) there is a lower crease (10) forming an obtuse angle with the lower wall (7) and an obtuse angle with the extreme lower surface (2), wherein both of the obtuse angles have an interior beneath the roof covering element (1) and wherein the interiors partially overlap.
