Average Cost of Replacing a Roof

The Typical Cost of Replacing a Roof in Illinois

The cost of replacing a roof depends on several factors, including the size of your home, the materials used, the complexity of the project, and additional considerations like labor, pitch, and waste percentage. While every home is unique, here are some general price ranges:

  • Small Houses (1,000–1,500 sq. ft.): $7,500–$12,000
  • Average Houses (2,000–2,500 sq. ft.): $15,000–$20,000
  • Large Houses (3,000–5,000 sq. ft.): $22,000–$40,000

Keep in mind that additional costs like old shingle removal, reinforcement, and cleanup can influence the total price.

Factors That Influence Roof Cost

  • Height and Pitch
    Roofs with steep pitches or multiple stories require more labor and specialized equipment, which can add $1,000 to $3,000 to the total cost.

  • Labor
    Labor can account for up to 60% of the total cost. Simpler projects may take 1–2 days, while complex roofs can require 3–5 days.

  • Materials
    Roofing systems include more than just shingles. Items like underlayment, flashing, and moisture barriers all factor into the final cost. High-quality materials ensure longevity but come at a premium.

  • Shingle Removal
    Removing old shingles costs between $1 and $5 per square foot, or $1,000 to $1,500 for most homes.

  • Reinforcement
    Heavy materials like slate may require structural reinforcement, costing $1,000 to $2,000 per rafter, with full roof reinforcements exceeding $10,000.

  • Waste Percentage
    Complex roofs require more materials due to waste from cuts and overlaps, typically 10–15% more.

  • Cleanup Fees
    Disposal and cleanup costs, including dumpster rental, range from $500 to $1,500 depending on the material type and quantity.

Roof Repairs vs. Roof Replacement

If your roof isn’t ready for a full replacement, repairs can extend its life. Here’s a look at average repair costs:

  • Small Repairs: Starting at $850
  • Medium Repairs: Around $2,500
  • Large Repairs: In the $7,500 range

Investing in timely repairs can save you from more costly replacements down the line.

Understanding Roofing Squares

A roofing square represents 100 square feet of roof surface. This unit simplifies material estimation. To calculate the roofing squares for your project:

  1. Measure the total square footage of your roof.
  2. Adjust for roof pitch using a pitch factor.
  3. Divide the adjusted square footage by 100.

For example, a 2,000 sq. ft. roof with a 6/12 pitch factor (1.158) and a 15% waste percentage will require 26.63 squares of materials.

Which Roofing Material Is Right for You?

Cost of a Metal Roof

Metal roofs are classified into two types: standing seam metal roofs and screw-down metal panel roofs.  A screw-down panel metal roof system (also known as an exposed fastener) is exactly what it sounds like: it is screwed down. Because the screws are screwed through the panel, there is no room for expansion or contraction.

Starting out, a screw down panel metal roof costs around $4.50 per square foot. A standing seam metal roof system is made up of panels that are locked together at the seams or mechanically seamed. When the metal heats up, this allows the panels to expand and contract freely. 
  • A 24 gauge steel standing seam metal roof will cost around $12.00 per square foot for a one-story house with a basic up and over roof, no penetrations, and no valleys.
  • A 24 gauge steel standing seam metal roof will cost around $15.00 per square foot for a one-story house with a moderately complex roof.

If you want to replace your residential roof with a metal roof, I recommend a standing seam metal roof. This does not preclude you from installing a screw-down metal roof over your home.

However, if you want to make the most of your metal roof investment, I recommend going with a standing seam metal roof system.

Cost of a Cedar Shake Roof

A cedar shake roof is a high-end roof system made of natural wood (cedar). While it performs the same functions as an asphalt or metal roof, it is one of the most visually appealing roofs you will see.

  • A cedar shake roof will cost around $14.00 per square foot for a one-story house with a basic up and over roof, no penetrations, and no valleys.
  • A cedar shake roof will cost around $18.00 per square foot for a more moderately complex roof.

The cost of your roof replacement will be influenced by the grade of cedar shake shingle you select, just as it is with asphalt shingles. Read this article on the different grades of cedar shake shingles to find the one that’s right for you.

Cost of a Slate Roof

A slate roof is a high-end roofing system constructed primarily of natural slate tiles and other slate roofing materials. It’s one of the most aesthetically pleasing and long-lasting roof systems on the market.

For labor and materials, a slate roof can cost as little as $15.00 per square foot and can cost as much as $30.00 or more per square foot.

A slate roof will cost at least four times as much as an asphalt roof. As a result, slate is one of the most expensive roofing materials available for roof replacement.
