To provide a venting heat insulating roof composite panel capable of providing the roof panel with air permeability without increasing the thickness of the panel and protecting a heat insulating layer with a thermal insulation reflection layer to improve the heat insulating function of the panel.
This roof composite panel provided with air permeability and a radiant heat elimination function is constituted by fixing vertical rails 2W, 2W' serving also as a sheathing roof board and rafter integrally at the center and on both sides of the heat insulating layer 2B, arranging a group of line grooves G and a thick wall 2T on a flat surface formed of the heat insulating layer 2B and the vertical rails 2W, 2W', arranging the thermal insulation reflection layer 2C on outer surfaces of the line groove G and the thick wall part 2T, and integrating and fixing a roof substrate member 2A with/on the heat insulating layer 2B from the upper face of the thermal insulation reflection layer 2C.
