Concrete tiles costs about $4 to $9 a square foot including installation. This puts a new roof with 2,000-square-foot at between $8,000 and $18,000. Ceramic roof tiles cost more at $6 to $12 per square foot including installation. This prices the same roof at $12,000 to $24,000. One of the factors increasing installation cost is the tileâs susceptibility to chipping or breaking.
