1 If removing and disposing of the existing roofing material isn't included in an estimate, this can add another $3-$5 a square foot or $510-$1,100 for a basic ranch-style home -- and costs go higher depending on location and the difficulty of the removal project. According to RoofHelp.com, the average lifespan for 20-year asphalt shingles is about 14 years in Phoenix, Arizona; 19.5 years in Minneapolis, Minnesota; and 20.8 years in Reading, Pennsylvania.
Note: many professional roofing contractors price their roofs on a per square basis, where one square is a 10 by 10 foot area or 100 square feet. Thus, your total cost in square terms could range from $350 to $1,200 per square of metal roofing installed. For comparison, most asphalt shingle roofs will cost anywhere from $300 to $700 per square installed depending on the material choice, roof complexity, installerâs credentials, your geographic area, time of the year, and so forth.
