PROBLEM TO BE SOLVED: To provide a fitting enclosure capable of constructing a roof made of metal easily and quickly and making it very rigid after the construction. SOLUTION: This roof board material consists of an overlapping mountain- shaped part A1 composed of a main board 1, a top part 2, an inclined side part 3 continuous with one end side in the direction of width of the top part 2 and one end side in the direction of width of the main board 1, and an outer inclined piece 4 formed on the other end side in the direction of width of the top part 2 and an overlapped mountain-shaped part A2 having an overlapped and inclined side part 6 continuous with the other end side in the direction of width of the main board 1. Fitting parts 8, 8 swelling toward the inside of the overlapping mountain-shaped part A1 and the overlapped mountain-shaped part A2 are formed in the inclined side part 3 and the overlapped and inclined side part 6, respectively, and locking bent pieces 9, 9 having a substantially recessed cross section are formed between upper ends 8a, 8a of the fitting parts 8, 8 and the inclined side part 3 and the overlapped and inclined side part 6, respectively.
