The additional quotes you receive will answer that for you. Also note that roof costs vary depending on geographic location. If you analyze the national average, you'll see roofing costs in the south, where roofing works have a lower total cost, as well as roofing costs on the coasts, where roofing costs tend to be higher. In the Cincinnati area, roofing costs fall in the mid-range.
