PROBLEM TO BE SOLVED: To prevent rainwater on a roof face from being concentrated in an eaves gutter or a valley gutter. SOLUTION: A channel structural member 11 having a plurality of channels 12 is provided so that the direction of channel becomes the direction of crossing for the direction A of roof grade to constitute a roof structure 10. Drainage slope is provided in the channel 12, and rainwater onto the roof face passes through the channel 12, flows into a roof end part on a lower side of water, and is discharged by a roof gutter 13 provided with sharply inclined drainage slope by matching with roof grade. Since the roof gutter 13 is different from the eaves gutter and the valley gutter having a conventional configuration and has sharp grade, rainwater on the roof face does not overflow even if rainwater is concentrated so that speedy drainage is performed. This roof structure 10 is applicable as a structure of a roof to be constructed newly and a structure provided on an existing roof when repairing the existing roof. COPYRIGHT: (C)2004,JPO
