PROBLEM TO BE SOLVED: To obtain a sheet material for roof having designing properties which has excellent durability, and naturally has a brick-like color tone with time after construction. SOLUTION: The stainless steel sheet for roof consists of a base steel sheet made of stainless steel and a Zn-Fe alloy layer formed on at least one side of the base steel sheet. The Zn-Fe alloy layer compositionally contains Fe of 0.5 to 10 g/m2, and is structurally consisting of one or more selected from aζphase, aηphase, aδ1 phase and aΓ1 phase. After being constructed as a roof, Fe in the Ze-Fe alloy phase is slowly oxidized, and the color of iron oxides is utilized to impart a brick-like color tone thereto.
