To provide a metal tile roof and a method of constructing the metal tile roof enabling the easy mounting of tile units on the bed of a roof and less accumulation of water in clearances between the bed and the tile units.

This metal tile roof 1 is formed by fixing tile stiffeners to the bed of the roof and fixing fixing pieces 12a and suspension elements 22 at the upper ends of the pile units to the tile stiffeners. The tile stiffeners are formed by arranging a plurality of block tables 21 parallel with each other in the longitudinal direction, and clearances for water channels for water flowing on the bed of the roof are formed between these block tables 21. The block table 21 is formed in a pyramid shape, and its side face is formed in a trapezoidal face supporting the fixing pieces 12a.
