A covering for roofs and vertical surfaces, having a prefabricated element comprising:

• a base layer having a waterproofing substrate;
• an upper covering, made of slate parts fixed by adhesive and placed in at least one row;
• means for the mechanical fastening of the slate parts;
• and
• means for anchoring the prefabricated element to the roof;
• wherein said base layer serves as a supporting element for the slate parts and projects, with respect to a surface covered by the slate parts, along two edges of said surface in zones overlapping with adjacent layers, in the formation of the covering;
• wherein on each base layer slate parts are placed forming a single row, the prefabricated elements being placed in the covering in an arrangement adjacent to the slate parts of consecutive rows partially overlapped with one another;
• and
• wherein the fastening means of the slate parts partially overlapped of consecutive rows comprise hooks arranged between parallel edges from which the overlapping is formed, said hooks being fixed to the lower slate parts and to the roof, and partially embracing the upper slate parts;
• and wherein the anchoring means to the roof comprise nails or joining elements which go through the hooks and are nailed in the roof.
