Roof Replacement Cost per Square Foot in 2026

2026 installed cost per roof square foot

| Roof covering | TheRoofBill model range per roof sq ft | |---|---:| | 3-tab asphalt shingles | $4–$6 | | Architectural asphalt shingles | $5.21–$6.82 | | Class 4 impact-resistant shingles | $6.50–$9.50 | | Corrugated metal | $5–$10 | | Standing seam metal | $10–$16 | | Concrete tile | $10–$16 | | Clay tile | $12–$18 | | Natural slate | $15–$28 | | TPO / EPDM membrane | $8.23–$10.54 |

These ranges are installed-covering planning inputs, not the full project total. Tear-off, disposal, permit, decking, flashing, ventilation, access, and roof geometry can change the estimate.

A simple example

Suppose a contractor measures 2,240 square feet of roof and quotes architectural shingles at $5.21–$6.82 per roof sq ft in the site’s base model. The covering portion is about $11,670–$15,280 before state labor adjustment, tear-off, permits, decking allowance, and optional details. This calculation illustrates how the unit rate works; it is not a local quote.

A “2,000-square-foot house” is not necessarily a 2,000-square-foot roof. The site’s example assumes a one-story 2,000-square-foot footprint, medium pitch, and simple gable; the slope adds area before the material rate is applied. Two houses with the same interior size can have very different roofs.

Why per-foot quotes differ

• Roof measurement method and whether waste is included
• Shingle grade, metal panel system, tile, or membrane specification
• One or more existing layers to remove
• Pitch, number of stories, hips, valleys, and penetrations
• Decking repairs, flashing, ventilation, ice barrier, and permit scope
• Local labor and disposal charges

Ask for both total price and measured roof area. A proposal that only says “$X per square” leaves out whether that means a 100-square-foot roofing square or a single square foot. Ask the roofer to define the unit and list exclusions.

Convert square feet to roofing squares

Divide measured roof area by 100: 2,240 sq ft ÷ 100 = 22.4 roofing squares before any material waste factor. The contractor should explain how waste is calculated for the chosen product and roof layout.

Sources and limits

Our installed ranges are 2026 planning estimates from the material model described in our methodology. We compare Homewyse roofing installation cost data, Angi’s 2026 roof replacement guide, Fixr’s roof replacement guide, and BLS roofer wage data. These sources measure different scopes, so we use them as planning inputs, not as a single quote database or a guarantee. Check current local bids and the product manufacturer’s specifications before choosing a roof.
