1 Having a roofing contractor remove (and dispose of) old roofing materials, then install asphalt shingles runs about $1-$4 a square foot, or a total of $1,700-$8,400 for a typical ranch-style home (1,700-2,100 square foot, gently sloping roof). Do-it-yourself materials run around $680-$3,700 for a typical one-story ranch-style home with a 1,700-2,100-square-foot, gently-sloping roof. 2  Standard gray asphalt shingles in a three-tab rectangle are the least expensive; expect to pay more for higher-end colors and styles.
Installation costs vary dramatically based on the size of your roof, its pitch, the condition of the roof, the company you choose and local labor rates. Very generally, expect installation to cost an additional $80-$200 per square. Removing old shingles usually costs an additional $80-$150 per square.
