A steel pipe roof structure is provided to drive a steel pipe forward and to form a horizontal groove simultaneously, to increase constructability and to shorten a period of construction. The invention relates to a steel pipe roof structure using a steel pipe(200) including fracture grooves(203) formed on one side at regular intervals to form a horizontal groove to be coupled with angles(206) of adjacent steel pipes laterally, wherein high-strength cutting members are formed on the front of the angles installed correspondingly to the fracture grooves and plural supports are installed to the inside of the steel pipe at regular intervals.
