To solve the problems of measures for coping with wind pressure by increasing the number of screws per unit area for preventing damage to a roof due to strong wind caused by typhoons or the like that the number varies depending on the strength of heat insulation material or waterproofing function material, and that secular deterioration of the waterproofing function material due to severe effects of sunbeam, peripheral environments, and natural environments such as rain and wind, making it difficult to let the roof free from damages due to strong wind by typhoons or the like.
In the metal roof backing system for a flat heat-insulation roof with a high wind pressure resistance, an upper surface part 7 of metal roof backing material 1 is finished to be flat to the utmost, and air quantity provided between that and the heat insulation material 2 is minimized. On the heat insulation material 2, the water proofing function material 3 is fixed by screws or nails to the metal roof backing material 1 to cover it, where bonding or welding is applied to an upper surface of a washer 13 or the like.
