The roof blocking sheet is composed of a sheet material which has heat blocking characteristics and blocks light and rain and to which a plurality of through holes with a diameter of 80 to 150 [mm] are disposed, wherein the opening rate of the overall through holes is set to 3% to 8% as well as the sheet material has a thickness of 0.2 to 2.0 [mm].
