         71 . The roof tile according to  claim 68 , wherein the adhesive strip is covered by a peelable sheet. 
     
     
         72 . The roof tile according to  claim 65 , wherein the decorative layer is compressed by the support layer. 
     
     
         73 . The roof tile according to  claim 65 , wherein the support layer comprises a metal sheet, preferably made of steel. 
     
     
         74 . The roof tile according to  claim 73 , wherein the metal sheet has a thickness less than 1 mm, preferably less than 0.7 mm, even more preferably less than 0.5 mm; and the metal sheet may have a thickness greater than 0.1 mm, preferably greater than 0.2 mm. 
     
     
         75 . The roof tile according to  claim 65 , wherein the support layer further comprises an extending portion that extends beyond an upper edge of the decorative layer. 
     
     
         76 . The roof tile according to  claim 65 , wherein the roof tile further comprises at least one anchoring element for anchoring the roof tile to a structure or framework. 
     
     
         77 . The roof tile according to  claim 76 , wherein the roof tile further comprises a reinforcement hole configured to prevent tearing the anchoring element from the support layer. 
     
     
         78 . The roof tile according to  claim 77 , wherein the reinforcement hole is formed in an extending portion of the support layer that extends beyond a side edge of the decorative layer. 
     
     
         79 . The roof tile according to  claim 78 , wherein the reinforcement hole is formed in the extending portion of the support layer close to the anchoring element but not on the anchoring element itself. 
     
     
         80 . The roof tile according to  claim 79 , wherein the reinforcement hole is disposed close to an extremity of the anchoring element so that the extremity and the attachment hole, especially the center thereof, are aligned along a substantially rectilinear line that is incident but not perpendicular to the side edge of the support layer. 
     
     
         81 . A roof tile comprising:
 a decorative layer comprising a ceramic body;   a support layer disposed below the decorative layer;   an upper edge;   a lower edge which is opposite to the upper edge;   two opposite side edges, the side edges being transverse to the upper edge; and   a first coupling element configured for being coupled to an adjacent roof tile in a roof covering, the first coupling element being provided on at least at one of the two opposite side edges of the roof tile, preferably said first coupling element is in the form of an adhesive strip; and   an anchoring element for anchoring the roof tile to a structure or framework, preferably the anchoring element is located in a position that is proximal to the first coupling element, more preferably the coupling element is located between a side edge of the decorative layer and the anchoring element.   
     
     
         82 . The roof tile according to  claim 81 , wherein the roof tile further comprises a support layer disposed below the decorative layer, preferably wherein the support layer comprises at least an extending portion that extends beyond an edge of the decorative layer, preferably a side edge of the decorative layer. 
     
     
         83 . The roof tile according to  claim 82 , wherein the first coupling element and the anchoring element are provided in or on the support layer, preferably in or on the extending portion. 
     
     
         84 . The roof tile according to  claim 82 , wherein the roof tile further comprises one or more attachment holes, preferably provided in the support layer, in particular in an extending portion thereof that extends beyond an upper edge of the decorative layer.
