1. A prefabricated element for covering roofs and vertical surfaces, the 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;fastening means for mechanical fastening of the slate parts
1. A prefabricated element for covering roofs and vertical surfaces, the 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;fastening means for mechanical fastening of the slate parts; andanchoring means for anchoring the prefabricated element to a 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 the 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; andwherein the fastening means of the slate parts partially overlapped in 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 overlapping 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;wherein the anchoring means for anchoring the prefabricated element to the roof or surface to be covered comprise nails inserted through holes drilled in the slate parts; and wherein the hooks between the partially overlapped slate parts of consecutive rows are U-shaped wire hooks, one of whose branches runs between every two consecutive slate parts and finishes in a downwardly bent section, which goes through the base layer, while the other branch of the hook runs over said slate part, directed towards the projecting zone of the base layer, so as to embrace the consecutive overlapped slate parts approximately three inches from a lower edge. 2. The prefabricated element according to claim 1, wherein the hooks are first hooks which comprise three consecutive sections, a central section which is supported and fixed on an upper surface of the slate parts placed in a lower position in the overlap of slate parts, from the overlapped edge, a lower end section, which is supported on said overlapped edge of the same slate part, and an upper end section which projects upwards from the central section, with which the upper end section forms an angle that is equal to or smaller than 90°, on which an edge of the another slate part, placed in overlapping position in the overlap of slate parts, rests. 3. A prefabricated element for covering roofs and vertical surfaces, the 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;fastening means for mechanical fastening of the slate parts; andanchoring means for anchoring the prefabricated element to a 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 formation of the covering;wherein on each base layer the 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;wherein the fastening means of the slate parts partially overlapped in 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 overlapping 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;wherein the hooks are second hooks which comprise an end extension which is supported and fixed on the roof by a nail and wherein the base layer is extended, from the edge parallel to the row of slate parts that projects from said row, into an upper wing which is upwardly bent, forming with said layer an angle that is smaller than 90°, while the opposite edge remains slightly retracted with respect to the adjacent parallel edge of the slate parts and is extended in a downwardly bent lower wing, forming with said layer an angle that is smaller than 90°; the lower wing of each base layer being coupled in the formation of the covering to the angle formed by the upper wing of the adjacent base layer placed in lower position in the overlap, and wherein the second hooks are mounted on top of the upper wing of the base layer. 4. The prefabricated element according to claim 3, wherein on the slate part edge parallel to and projecting from the lower wing of the base layer a third hook is coupled, which is extended underneath said slate parts and finishes in a pin which is bent into a 180° angle which is coupled on said lower wing. 5. The prefabricated element according to claim 4, wherein the first and second hooks are made of metal sheet and the third hook is obtained from a metal rod. 6. The prefabricated element according to claim 3, wherein the base layer forms downwardly projecting nerves parallel to the row of slate parts, as a support on the roof.
