PROBLEM TO BE SOLVED: To provide a roof structure which can hardly cause accumulation of moisture and humidity inside a roof and which can easily prevent damage to a roof material and a roof substrate.SOLUTION: In a roof material 10, a plurality of protrusive streak portions 11 are formed at predetermined intervals in a direction orthogonal to an eaves ridge direction, and a fixing piece 15 protruding downward with respect to a flat plate portion 12 formed between the protrusive streak portions 11 is formed at one end. The roof material 10 is laid on a roof substrate 30 in such a manner that the protrusive streak portions 11 cover bases 1 fixed to the roof substrate 30. The fixing piece 15 is laid by being fixed to the roof substrate 30. A discharge space 7 is formed between the roof material 10 and the roof substrate 30. |
