Abstract

A roof covering element, a modular roofing sheet, made of a plate material, consisting of a first and second side edge, an upper edge and a lower edge, having a series of modules substantially parallel to the side edges forming at least one surface, containing ribs (walls) parallel to the upper and lower edges, characterised by that 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 ending surface (4) of the roof covering element (1); between each of {n} central walls (6) and each of {n} surfaces (3) there is a central crease (9) forming an obtuse angle with a central wall (6) and an obtuse angle with the surface (3); 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 n is a natural number of n>0.
