Snow-melting roof tile and roof snow-melting system including same

1. A snow-meting roof tile, comprising:

a metal roof tile including

a main cover part,

a first end portion and a second end portion, which are disposed at both ends in a first direction of the main cover part,

a first bending part bent upwardly from the first end portion, and

a second bending part bent downward from the second end portion;

a heat generation part located on a lower portion of the metal roof tile and including

a heating body for generating heat, and

a connecting part for connecting one heat generation part to another heat generation part or a cable,

wherein the heating body comprises,

a heating material generating the heat by applying a power to the heating material, and

an insulating and waterproofing part configured to surround an exterior of the heating material for insulation and waterproof; and

a fixing part for fixing the heat generation part to the metal roof tile,

wherein the heat generation part generates heat to heat the metal roof tile, thereby the heat of the heat generation part is transferred to an upper portion of the metal roof tile so as to melt snow on the metal roof tile,

the insulating and waterproofing part comprises an upper side insulating and waterproofing part of which an upper surface has an adhesive force, and a lower side insulating and waterproofing part of which a lower surface has an adhesive force,

the upper side insulating and waterproofing part has an area greater than one of the heating material and cover entirely the heating material,

the lower side insulating and waterproofing part has an area greater than one of the upper side insulating waterproofing part and cover entirely the upper side insulting and waterproofing part, and

the fixing part includes a portion, which extends to the outside without overlapping the lower side insulating and waterproofing part and the upper side insulating and waterproofing part.

2. The snow-meting roof tile of claim 1 ,

wherein the metal roof tile comprises a pair of overlapping parts, which are disposed at each of both ends in a second direction crossing the first direction, and overlap another metal roof tile adjacent to the metal roof tile, and

wherein the heating body does not overlap at least one of the pair of overlapping parts.

3. The snow-meting roof tile of claim 1 , further comprising a cable passing part provided in at least one of the first bending part and the second bending part and protruding towards the outside.

4. The snow-meting roof tile of claim 3 ,

wherein the first bending part is disposed towards an upper side of an inclined surface of a roof and the second bending part is disposed towards a lower side of an inclined surface of the roof, and

wherein the cable passing part comprises a first cable passing part protruding upwardly in the first bending part.

5. The snow-meting roof tile of claim 4 , wherein the first cable passing part includes a portion protruding towards the second bending part.

6. The snow-meting roof tile of claim 4 , wherein the cable passing part further comprises a second cable passing part protruding towards the outside.

7. The snow-meting roof tile of claim 6 , wherein a lower end of the second cable passing part is formed to be recessed upwardly.

8. The snow-meting roof tile of claim 1 , wherein the fixing part is disposed under the heating body and includes a portion attached to a bottom surface of the heating body and a portion attached to a bottom surface of the metal roof tile.

9. The snow-meting roof tile of claim 1 , wherein the metal roof tile further comprises a stone chips attached to an upper surface of a metal part.
