1 Concrete tiles cost about $4.50-$9 a square foot for installing standard-grade tiles, or $7,650-$19,000 for a basic roof on a one-story ranch-style home (1,700-2,100 square feet of roof). 2  It runs $7-$10 or more a square foot for deluxe concrete tiles, or $11,900-$21,000 or more for 1,700-2,100 square feet. If you're switching to tile from a lighter-weight roofing material, you'll need to have the building inspected by a building engineer and the roof supports possibly reinforced or replaced, easily adding $1,000-$10,000 or more to the cost.
