Understanding Your Roof Replacement Costs
Replacing a roof is one of the most significant investments a homeowner will make. The total cost isn't just about the shingles; it involves labor, waste disposal, local permit fees, and the structural complexity of your home.
Key Factors That Influence the Price
Material Choice: This is the biggest variable. Asphalt shingles are cost-effective (averaging $400-$700 per "square"), while slate or premium tile can exceed $2,000 per square.
Roof Size: Contractors measure roofs in "squares." One square is equal to 100 square feet. A 2,000-square-foot roof equals 20 squares.
Roof Pitch: Steeper roofs are more dangerous and difficult to work on. They require specialized safety equipment and more labor hours, increasing the overall cost by 15% to 50%.
Tear-off Costs: If your contractor has to remove existing layers of old shingles, expect to pay between $1.00 and $3.00 per square foot for labor and disposal fees.
Typical Material Cost Examples (Per Sq. Ft.)

Frequently Asked Questions
How long does a roof replacement take? Most residential roof replacements take between 1 and 3 days, depending on the size and complexity of the roof.
Should I repair or replace my roof? If your roof is over 20 years old or has widespread leaks and missing shingles, a full replacement is usually more cost-effective in the long run than frequent repairs.
