Roofing board

The present invention relates to roofing material to be connected with a further roofing material under a condition that respective sides of the roofing material and the further roofing material are overlapped with each other, including a main body having a substantially flat plate shape and a fitting part formed at an end of the main body. The roofing material further includes at least one positioning marker which is provided to the fitting part so as to indicate a position of an overlap between the respective sides.

Roofing material and roof structure

An approximately planar roofing material body is arranged adjacent to another roofing material body. A side end part of the roofing material body is overlapped and laid to the another roofing material body. The roofing material body is provided with an inclined piece formed at a side end edge part of the roofing material body so as to be inclined downward. Further, a tip of the inclined piece (an inclined-piece tip) of the roofing material body is formed so as to abut on a front face bent downward of the another roofing material body laid to a downside of the roofing material body.
