Roof Replacement Cost Calculator (2026)

The national average cost to replace a roof in 2026 is $9,800, with most homeowners spending between $5,500 and $18,000 for architectural asphalt shingles. Costs range from $5,500 (budget 3-tab asphalt, mid-size home) to $70,000+ (natural slate on a large home). Your final cost depends primarily on material choice, roof size, pitch, and your location.

Most residential roof replacements take 1–3 days for asphalt shingles on an average-sized home. Larger homes, steep pitches, or premium materials like slate or standing seam metal can extend the timeline to 3–7 days. Weather delays are the most common cause of schedule extensions.

Homeowners insurance typically covers roof damage from sudden, unexpected events such as hail, wind, falling trees, or fire. Gradual wear, age-related deterioration, and lack of maintenance are generally not covered. Most policies have a deductible ($1,000–$2,500 is common). File a claim and get a roofing contractor's assessment before committing to any work.

Always get at least 3 quotes. Verify the contractor is licensed, insured, and has a physical address. Ask for recent local references. Check reviews on Google and the BBB. Avoid contractors who demand full payment upfront or pressure you to sign immediately after a storm — these are common storm-chasing scam signs.

Metal roofs cost $15,000–$36,000 vs. $7,500–$13,500 for architectural asphalt on an average home. Metal lasts 40–70 years vs. 25–30 for quality asphalt. The break-even analysis depends on how long you'll own the home: if you plan to stay 20+ years, metal often wins financially when factoring in avoided replacement costs, lower insurance premiums, and potential energy savings. Metal also adds higher resale value. For homeowners planning to move within 5–10 years, premium asphalt is usually the better value choice.

Overlaying (adding new shingles over old) is possible if: you currently have only 1 layer, the existing deck is sound, and local codes permit it. Savings: $0.50–$1.50/sqft by skipping tear-off. Drawbacks: hides potential deck damage, voids many shingle manufacturer warranties, makes future replacement more expensive, adds weight to your roof structure, and shortens the new shingles' lifespan. Most roofing professionals recommend full tear-off for the best long-term result. If your existing shingles are curling, your deck has rot, or you've already layered once — full tear-off is the only option.

Common roof financing options: (1) Contractor financing: many roofers offer 0% promotional financing for 12–18 months through GreenSky, Synchrony, or similar. Good for those who can pay it off quickly. (2) Home equity loan/HELOC: rates typically 7–9% — best for significant equity and longer repayment. (3) Personal loan: rates 8–18% depending on credit score — no home equity required. (4) Insurance claim: if damage was from a covered event (hail, wind), your insurer pays minus deductible. Always get the insurance claim settled before signing with a contractor.

Signs you need replacement (not repair): roof is 20+ years old, curling or buckling shingles across large sections, granules filling your gutters (shingles are deteriorating), sagging roof deck, daylight visible through roof boards in attic, widespread moss/algae indicating water retention, multiple leaks in different areas. Rule of thumb: if repair costs exceed 30% of replacement cost, or your roof is within 5 years of end-of-life, replace it. A free inspection from a licensed contractor will clarify — get 2–3 opinions before deciding.

A 2,000 sq ft house typically has a roof of 22–25 squares (2,200–2,500 sq ft of roof surface, accounting for pitch and overhang). At $4–$7/sq ft installed, expect $8,800–$17,500 for asphalt shingles. Metal roofing on the same house runs $15,000–$35,000. Use the calculator above to refine your estimate by material, pitch, and state.

A 1,500 sq ft house usually has 1,600–1,900 sq ft of roof area (16–19 squares). Budget $7,000–$13,500 for asphalt shingle replacement. The national average for this size runs around $7,500–$9,500. Metal roofing on a 1,500 sq ft home costs $12,000–$24,000. These estimates assume standard pitch (4/12–6/12); steep pitches add 15–25% to labor costs.
