The Cost to Replace A Roof. According to our roof installation cost estimator, the average price to install or replace a roof is $5,951. There are many factors that influence the final cost of a roof installation. Many of them vary over time and across locations, making them difficult to predict. For this reason, there is a wide range of possible prices. At the high end, people pay as much as $11,000; at the low end, they may pay as little as $3,000.
That being said, most roofing contractors (and many insurance companies) will price their roof replacement services within $3.50 to $5.00 per square foot or $350 to $500 per square of architectural shingles installed. A square is equal to 100 square feet of roof surface. An average roof size is about 1,700 square feet.
