What Drives Roof Replacement Cost
Replacing a roof costs more than a new install on fresh construction because the old roof must be torn off and hauled away. The biggest drivers are roof size (in squares), the material you choose, roof steepness and the number of stories — multi-story homes cost more per square because of staging and safety overhead.
Cost Structure
- Materials: shingles or metal panels, underlayment and accessories
- Labor: installation, adjusted upward for 2+ story homes
- Tear-off: removing existing shingles down to the deck
- Disposal: dumpster and landfill or recycling fees
Worked Example
A 1,677 sq ft single-story home with asphalt shingles and 10% waste ≈ 18.4 squares. Including tear-off and disposal, expect a planning range of roughly $9,000–$16,000. A standing-seam metal roof on the same house runs roughly double.
What You Need
Your roof area, the roofing material you want, and how many stories your home has — a two-story home usually adds labor and access cost. Tear-off and disposal are already included in the estimate, so you don't need to add them separately.
Assumptions & Limitations
Price ranges are national averages derived from Angi (2026) and cross-checked against Fixr (2026), refreshed quarterly. Excludes decking repairs, permits, skylights, chimneys and structural work. This estimate is not a contractor quote.
Frequently Asked Questions
How long does a roof replacement take?
Most single-family asphalt shingle roofs are replaced in 1–3 days by a professional crew, weather permitting.
Is it cheaper to replace a roof in winter?
Some contractors offer off-season discounts, but cold weather can affect shingle installation. Balance savings against installation quality.
