[Summary of the present invention]
The roof of the present invention is a roof installed on a beam fixed to a support column, and is configured by arranging a plurality of metal-formed roofing materials side by side, and at least one of the plurality of roofing materials. One roofing material is configured as an illuminated roofing material in which an illuminating tool is attached to a lower surface portion, and is characterized by having a heat blocking layer covering the upper surface of the illuminated roofing material.
According to the roof of the present invention, when the temperature of the upper surface of the roof rises due to the sunlight, the illuminated roofing material is heat-shielded by the heat-shielding layer covering the upper surface, so that the illuminated roofing material receives the sunlight. It is possible to suppress the temperature from being directly received and becoming high, and thereby it is possible to suppress the temperature rise of the luminaire due to the heat transferred from the illuminated roofing material side.

In the roof of the present invention, the heat blocking layer is composed of a heat insulating cover including a cover material along the longitudinal direction of the illuminated roofing material and a heat insulating material along the cover material. Both side edges along the longitudinal direction of the roofing material are attached to the roofing material adjacent to the illuminated roofing material among the roofing materials, and the heat insulating material is provided between the covering material and the illuminated roofing material. It may be arranged.
According to such a configuration, since the heat insulating material is arranged between the cover material and the illuminated roofing material, the heat insulating material can insulate between the cover material and the illuminated roofing material that receive solar radiation. Furthermore, since both side edges of the cover material are attached to the roof material adjacent to the illuminated roof material, the cover material and the roof material do not come into direct contact with each other, and the heat of the cover material is not directly transferred to the illuminated roof material. It is possible to suppress the temperature rise of the luminaire.

The space may be configured as a heat insulating space.
According to such a configuration, while the gutter portion of the illuminated roofing material can be used as a heat insulating space for insulating solar heat, rainwater or the like can flow to the gutter portion by exhibiting the original function of the gutter portion in rainy weather.

In the roof of the present invention, the heat blocking layer may be composed of a heat ray reflecting layer along the upper surface portion of the illuminated roofing material.
According to such a configuration, the heat blocking layer can be formed thinner than, for example, as compared with the case where a heat insulating material covering the upper surface portion of the illuminated roofing material is installed. Therefore, the appearance shape of the roofing material having the heat blocking layer and the roofing material not having the heat blocking layer are not significantly different, and the appearance design can be improved.
Further, in a factory, a laminated sheet having a heat ray reflecting layer may be attached to the upper surface of an illuminated roofing material, or a heat ray reflecting layer may be vapor-deposited on the upper surface of an illuminated roofing material in advance, for example, for lighting. On-site work of attaching a cover material or the like covering the upper surface of the roofing material to the roofing material adjacent to the illuminated roofing material can be eliminated, and the construction can be simplified.

In the roof of the present invention, the upper surface portions of the plurality of roofing materials may be formed flat.
According to such a configuration, a flat roof upper surface can be configured over a plurality of roofing materials. Further, rainwater or the like can flow the upper surface portions of a plurality of roofing materials along the slope of the roof.
