PROBLEM TO BE SOLVED: To provide a corner tile set enabling the reduction of the tile waste material produced at a construction site and the large reduction of construction cost. SOLUTION: This corner tile set is used for the corner ridge or corner valley of a roof where generally square crosspiece tiles are roofed staggered. The corner tile set comprises four types of corner tiles formed of first corner tiles 11, 21, 31, 41 laid down, in order, from the lower stage to the upper stage of the corner ridge or the corner valley; second corner tiles 12, 22, 32, 42; third corner tiles 13, 23, 33, 43; and fourth corner tiles 14, 24, 34, 44. The shapes and dimensions of the second corner tiles 12, 22, 32, 42 are so determined according to the shape and dimensions of the first corner tiles that first cut lines LR1, LL1, second cut lines LR2, LL2, third cut lines LR3, LL3, and fourth cut lines LR4, LL4 are arranged in a generally straight line. The shape and dimensions of the third corner tiles 13, 23, 33, 43 are determined according to the shape and dimensions of the second corner tiles. The shape and dimensions of the fourth corner tiles 14, 24, 34, 44 are determined according to the shape and dimensions of the third corner tiles. COPYRIGHT: (C)2009,JPO&INPIT
