To improve execution and airtightness by projecting the upper plate of the ventilation roof of an integral unit structure forming a ventilation layer between a sheathing roof board and the upper plate from the frame material of both the side edges of an integral unit.
A heat insulation material is filled inside a rectangular frame material 2, both the upper and lower faces of the frame material 2 are covered with an upper plate 4 and a lower plate 5, a plurality of roof rafters 6 are attached, and a sheathing roof board 7 is attached thereon to make integral unit structure forming a ventilation layer 8 between the sheathing roof board 7 and the upper plate 4. Both the right and left side edges of the upper plate 4 are projected to the outside of the frame material 2, which is fitted and mounted between two inclined beams 13, the edge part 4a of a frame material 4 is supported on the upper face of the inclined beam 13, and fixed by nails. A projection part is fixed by being supported on the inclined beam 13. Thereby each panel 1 can be fixed more easily and surely than nailing or the like, execution is improved, and airtightness between each ventilation roof panels 1 and the inclined beam 13 is improved.
