How much does a roof replacement cost? (National averages)

Roofers price by the "square" — 100 square feet of roof. Most quotes you'll see are really a per-square rate ($450–$850/square for architectural asphalt is typical) multiplied by your roof's size, plus line items for tear-off, permits, and extras.

For a full replacement in 2026, these are the realistic national ranges for a complete job — materials, labor, tear-off, and disposal included:

Architectural asphalt is what ~80% of American homes get, so if you're budgeting without a quote yet, $9,000–$17,000 on a 2,000 sq ft roof is the number to plan around.

Roof replacement cost by roof size

Roof size is the single biggest cost driver. Note this is roof square footage, not your home's living space — a 2,000 sq ft house usually has a ~2,200–2,600 sq ft roof once pitch and overhangs are factored in.

Rounded to the nearest $250. Assumes single-layer tear-off included, moderate pitch, average-cost region.

True cost over time: price per year of roof life

Sticker price isn't the whole story. A $26,000 metal roof that lasts 55 years costs less per year than a $13,000 asphalt roof replaced every 27:

The lifetime costs converge more than people expect. The real reasons to pick asphalt anyway: lower upfront cash outlay, easier to find installers, and most homeowners move before year 30. The real reasons to pick metal: you plan to stay, you want the energy savings (reflective metal cuts cooling costs), or your insurance offers a discount for impact-rated roofing.

Three real-world examples

Budget: simple ranch in the South. 1,500 sq ft roof, single story, low pitch, one old layer. Architectural asphalt: ~$8,800 all-in, realistically $7,500–$10,500.

Typical: two-story suburban home in the Midwest. 2,000 sq ft roof, moderate pitch with a couple of valleys, one old layer. Architectural asphalt: ~$14,900 all-in, realistically $13,000–$17,500.

Premium: steep, complex roof in the West. 2,800 sq ft, steep pitch, dormers and skylights, two old layers to remove. Standing-seam metal: ~$55,000 all-in, realistically $48,000–$63,000.

Notice how fast complexity compounds: the premium roof isn't just bigger — the steep pitch, extra tear-off layer, and higher-cost region each multiply the base price.

Where the money goes: materials vs. labor

On a typical $12,000 asphalt shingle job, the split looks roughly like this:

• Labor: ~55–60% ($6,600–$7,200) — tear-off crew, installation, flashing work, cleanup. Roofing is dangerous, skilled work; this is why the cheapest bid is rarely the bargain it looks like.
• Materials: ~35–40% ($4,200–$4,800) — shingles, underlayment, ice-and-water shield, drip edge, vents, nails.
• Permits, dumpster, and fees: ~5% ($400–$600).

The labor share climbs on steep or complex roofs (more staging, slower work, safety equipment) and falls slightly on simple single-story ranches. If a quote shows labor under 40% of the total, ask what's being skipped.

What drives the price up or down

Pitch and complexity. A steep roof (8/12 pitch or more) or one cut up with valleys, dormers, and skylights can add 15–30% over a simple gable roof of the same size. More flashing, more cutting, slower and riskier labor.

Layers to remove. Tear-off and disposal runs roughly $1–$2.50 per sq ft depending on the number of layers and local dump fees. Two old layers instead of one can add $2,000+ on an average roof. (Building codes in most areas allow a maximum of two shingle layers — but layering new shingles over old ones shortens the new roof's life and voids some manufacturer warranties.)

Region. Labor rates and disposal costs vary enormously:

Decking condition. If the crew finds rotted plywood under the old shingles, replacement decking runs $2–$5 per sq ft of affected area. A reputable contractor includes a per-sheet price for this in the quote before starting — if yours doesn't, ask.

Timing. Late spring and early fall are peak season (highest prices, longest waits). Late fall and winter often bring 5–10% discounts in cold climates, since crews want to stay busy.

Costs people forget to budget for

• Underlayment upgrade: basic felt is standard; synthetic underlayment or full ice-and-water shield in valleys and eaves adds $0.50–$1.00/sq ft but is worth it in snow and ice country.
• Flashing: chimney flashing replacement $300–$600; skylight re-flashing $200–$400 each. Reusing 20-year-old flashing on a new roof is a classic corner-cut.
• Ventilation: ridge vent installation or attic ventilation fixes, $300–$800. Poor ventilation cooks shingles from underneath and voids warranties.
• Permits: $250–$500+ depending on municipality. The contractor should pull these, not you.
• Gutter work: gutters usually survive a re-roof, but expect $200–$400 in minor gutter repair/reattachment.
• Landscaping protection: not a line item, but ask how they'll protect plantings and siding — and what happens if they don't.

How to read a contractor quote

A real quote is a line-item document, not a single number on a napkin. Demand these items spelled out:

1. Material brand, line, and color — "architectural shingles" isn't enough; you want the manufacturer and product line (it determines the warranty).
2. Number of squares — so you can compare per-square pricing across bids.
3. Underlayment type — felt vs. synthetic, and where ice-and-water shield goes.
4. Tear-off scope — how many layers, disposal included, dumpster placement.
5. Flashing scope — what's replaced vs. reused, itemized.
6. Decking replacement price — per-sheet cost if rot is found, agreed in advance.
7. Permit responsibility — contractor pulls it, cost itemized.
8. Workmanship warranty — length in years, in writing, separate from the manufacturer warranty.
9. Payment schedule — never more than 10–20% down for a standard residential job.

Get three quotes. If they're within 10–15% of each other, the market has spoken. If one is 30% lower, something is missing — usually insurance, warranty, or scope.

Red flags in a roofing bid

• No proof of license and insurance. Ask for the certificate of insurance directly from their insurer, not a photocopy they hand you.
• More than 20% down (or full payment upfront) on a standard job.
• "Sign today" pressure or a price that's only good if you decide on the spot.
• Vague line items — "roofing system: $14,000" with no breakdown.
• No written workmanship warranty, or a warranty shorter than 5 years.
• Door-knockers after a storm offering to "handle your insurance claim." Some are legitimate local roofers; many are not. Verify independently.
• Asking you to sign over your insurance check before work begins.

Repair or replace?

Not every aging roof needs a full replacement. As a rule of thumb:

• Repair if the roof is under ~15 years old (asphalt), damage is localized (a few missing shingles, one flashing failure, a single leak), and the decking is sound.
• Replace if it's past 20–25 years, you're seeing widespread granule loss or curling, leaks appear in multiple spots, or a repair would cost more than ~30% of replacement.

Frequently asked questions

Does homeowners insurance pay for a new roof? Usually only for sudden damage — hail, wind, fallen trees — not age or wear. Insurers also depreciate older roofs, so a 20-year-old roof may only get partial coverage. Full details in our insurance guide.

How long does a replacement take? One to three days for a typical asphalt shingle roof. Metal, tile, and slate take longer — up to two weeks for slate.

Can new shingles go over the old ones? Most codes allow two layers maximum, but it's generally not recommended: it hides decking problems, adds weight, and shortens the new roof's lifespan. A full tear-off costs more upfront and is almost always the better value.

What's the best time of year to replace a roof? Late spring through early fall for ideal installation conditions. Late fall and winter can mean lower prices in cold climates, though adhesives need adequate temperatures to seal properly.

How do I finance a roof replacement? Options range from home equity lines (usually the cheapest borrowing) to contractor financing to credit cards (usually the most expensive). We compare the real total costs in our roof financing guide.

How long will my new roof last? Architectural asphalt: 25–30 years. Metal: 40–70. Tile: 50+. It depends heavily on installation quality and ventilation — which is why the contractor matters as much as the material.

Will a new roof lower my homeowners insurance? Sometimes. Impact-resistant (Class 4) shingles can earn discounts of 5–25% in hail-prone states. A brand-new roof of any type may also qualify for a "new roof" discount with some carriers — ask your agent before and after the job.

Do I need new gutters too? Usually not. Gutters are removed and reattached during a re-roof; budget $200–$400 for minor gutter repair, and only replace them if they're already failing.

How do I verify a contractor's license and insurance? Check your state's contractor licensing board website (most have a public lookup), and ask the roofer for a certificate of insurance sent directly from their insurer — not a photocopy. No certificate, no contract.
