System and method for installing roof tiles

1. A method for installing a roof tile covering on a roof structure comprising the steps of:

providing a plurality of roof tiles comprising a porcelain body above the roof structure, the porcelain body comprising an attachment hole;

placing and fixing a part of the plurality of roof tiles onto the roof structure thereby forming a horizontal row;

interrupting the horizontal row at a distance from a hip or valley of the roof structure, wherein the distance is larger than the width of the roof tile;

cutting at least one roof tile to provide a triangular or trapezoidal piece comprising one or more attachment holes;

placing and fixing the triangular or trapezoidal piece onto the roof structure substantially in correspondence of the hip or valley thereby leaving a gap between the triangular or trapezoidal piece and the plurality of roof tiles in the horizontal row; and

placing and fixing at least one roof tile on the roof structure in correspondence of the gap thereby filling the gap itself,

wherein the roof tile covering comprises a plurality of horizontal rows of roof tiles.

2. The method of claim 1 , wherein all of the steps are repeated for each of the plurality of horizontal rows of the roof tile covering.

3. The method of claim 1 , wherein the cutting step comprises cutting along a first cutting line that is inclined with respect to an upper edge of the roof tile.

4. The method of claim 1 , wherein the cutting step provides a triangular or trapezoidal piece comprising a plurality of attachment holes.

5. The method of claim 1 , wherein the cutting step is repeated to provide a plurality of triangular or trapezoidal pieces having the same form and dimension.

6. The method of claim 1 , wherein the placing and fixing the triangular or trapezoidal piece comprises gluing the triangular or trapezoidal piece to the roof structure.

7. The method of claim 6 , wherein the placing and fixing the triangular or trapezoidal piece further comprises nailing or screwing the triangular or trapezoidal piece to the roof structure.

8. The method of claim 1 , wherein the step of placing and fixing the at least one roof tile for filling the gap comprises cutting one of the roof tiles along a second cutting line parallel to a side edge of the roof tile.

9. The method of claim 1 further comprising a step of placing the roof tiles of adjacent horizontal rows on the roof structure with a regular offset pattern.

10. The method of claim 1 further comprising a step of placing the roof tiles of adjacent horizontal rows on the roof structure with a random offset pattern.

11. The method of claim 1 further comprising the step of placing the roof tiles of adjacent horizontal rows on the roof structure in such a way that the adjacent horizontal rows are partially overlapped.

12. The method of claim 1 further comprising a step of placing an under layer on the roof structure.

13. The method of claim 1 further comprising:

providing a nail for being inserted in the attachment hole of the roof tile;

providing a nail gun for pushing the nail into the attachment hole, the nail gun comprising a centering element;

coupling the centering element with the attachment hole of the roof tile; and

pushing the nail into the attachment hole for installing the roof tile on the roof structure.

14. The method of claim 3 , wherein the first cutting line is inclined at an angle of 22° with respect to the upper edge of the roof tile.

15. The method of claim 9 , wherein the offset pattern is a regular offset pattern.

16. The method of claim 15 , wherein the regular offset pattern is a 50% offset pattern.

17. The method of claim 11 , wherein the partial overlap between the adjacent horizontal rows is from 20% to 35%.

18. The method of claim 12 further comprising a step of placing the roof tile on the under layer immediately following the step of placing the under layer on the roof structure.
