Roofing Cost Calculator 2026 — Estimate Roof Replacement Cost Instantly

The national average for roof replacement in 2026 is $8,000–$20,000 for a typical 2,000 sq ft home with asphalt shingles. Metal roofs run $15,000–$35,000, tile roofs $18,000–$45,000, and slate roofs $25,000–$60,000+. Labor typically accounts for 40–60% of the total project cost.

Asphalt shingles are by far the most affordable roofing material at $3–$5 per square foot installed. They last 20–30 years with proper maintenance. 3-tab shingles are the cheapest option; architectural (dimensional) shingles cost slightly more but offer better durability and curb appeal.

Measure the length and width of your home's footprint at ground level and multiply them together. Then multiply by a pitch factor: 1.0 for flat, 1.15 for a 4/12 pitch, 1.25 for a 6/12 pitch, 1.41 for a 9/12 pitch. This accounts for the additional surface area created by the slope.

Tear-off involves removing the existing roofing material, disposing of it at a landfill or recycling facility, and inspecting the decking underneath. The cost is typically $1.00–$2.00 per square foot. Some areas allow installing new shingles over old ones (overlay), which skips tear-off but is generally not recommended by roofing professionals.

Steeper roofs require more safety equipment, take longer to install, and are more physically demanding — driving up labor costs by 15–30%. A 12/12 pitch (45-degree angle) can add 30–50% to the total project cost compared to a low-slope roof. Complex multi-gable designs with many valleys and angles cost even more.

If your roof is under 15 years old with isolated damage, repair is usually cost-effective (typically $300–$1,500). If it's over 20 years old, has widespread granule loss, multiple leaks, or sagging decking, replacement is the smarter long-term investment. The break-even point is typically when repair costs exceed 30% of full replacement cost.
