PROBLEM TO BE SOLVED: To provide a heat insulating roof structure capable of securing excellent air permeability by forming space between a roof board 24 and a heat insulating board 1 for a roof, the space communicating not only in the slope direction of a roof but also in the circumferential direction of the roof.SOLUTION: In a heat insulating roof structure, a heat insulating board 1 for a roof, made of synthetic resin foam, is fitted between two adjoining roof framework materials 22 and 22 forming a ridge beam, a purlin 21a or a girder beam 21b and is installed along the roof slope. And a rafter 23 is installed on the roof framework materials 22, and a roof board 24 is installed on the rafter 23. At the same time, a clearance d is formed between the lower surface of the rafter 23 and the top face of the heat insulating board 1 for a roof. |
