Average Cost to Tear Off and Replace Roof

First things first, let’s talk about the basics. The cost of replacing a roof isn’t just about slapping on new shingles. You’ve got to consider the whole operation, including tearing off the old stuff.

What Influences the Cost?

  • Size of Your Roof: Bigger roofs require more materials and labor.
  • Type of Materials: Asphalt shingles are usually the most budget-friendly, but if you’re dreaming of slate, prepare to pay more.
  • Labor: Skilled labor isn’t cheap, especially for a job that needs to be done right.

On average, homeowners might spend between $5,000 and $10,000 for a complete tear-off and replacement, but those numbers can swing dramatically based on the factors above.

Roof Replacement Cost Per Square

In the roofing world, costs are often discussed in terms of “squares.” A square in roofing lingo is 100 square feet of roof surface.

Here’s the Deal:

  • Cost Per Square: Prices can range from $350 to $1,500 per square, depending on your material choice and other project specifics.
  • Why It Matters: Calculating the cost per square gives you a more accurate estimate based on your roof’s size and the materials you’re eyeing.

What You Need to Know:

  • Material Availability: In some areas, certain materials might be pricier due to shipping costs.
  • Labor Costs: These can vary significantly from one region to another.
  • Local Regulations: Permits and codes can also add to the cost, depending on where you live.


In high-cost living areas, you might pay 20% to 40% more for your roof replacement than in more affordable regions.
