PROBLEM TO BE SOLVED: To provide an internal pressure assisting roof structure for reducing sharing of a vertical load of a roof shared by a roof structural material, by operating internal pressure being a difference between outside atmospheric pressure and indoor atmospheric pressure set a little larger than the outside atmospheric pressure as auxiliary support force of the roof. SOLUTION: This internal pressure assisting roof structure is constituted so as to operate the internal pressure Q being differential pressure between the indoor atmospheric pressure and the outside atmospheric pressure by setting the indoor atmospheric pressure larger than the outside atmospheric pressure, on the indoor surface side of the roof composed of a rigid structural material 4 and covering an indoor space 3 capable of holding airtightness.
