Roof Replacement Cost (2026): Full Breakdown

By HomeCost Guide · Updated October 2026 · Angi's October 2026 figure for shingle roof replacement, from surveyed homeowner project costs

Replacing a roof costs $7,500 to $24,000 for most American homes, averaging $10,500 for asphalt shingles (Angi, October 2026). It's the priciest exterior project most homeowners ever undertake — and the one with the most ways to overpay or under-buy. The range is wide because roof cost is four costs multiplied: your roof's size, the material, the roof's complexity, and local labor rates.

This flagship guide puts it all in one place: installed costs by material (asphalt, metal, tile, wood, slate), per-square-foot math for your own roof, quote anatomy (labor, materials, tear-off, permits, decking contingency), and what actually moves the number — pitch, complexity, underlayment and flashing details, timing, warranties. Budgeting a planned replacement or facing a storm emergency, start here. This flagship guide puts it all in one place: installed costs by material, per-square-foot math for your own roof, full quote anatomy, and the factors that actually move the number — pitch, complexity, flashing details, timing, and warranties.

1. Roof Replacement Cost (2026): Full Breakdown cost breakdown

Angi's figures are consistent: $7,500–$24,000 per project (avg $10,500) and $4–$11 per square foot across materials — a 1,700 sq ft roof at $6/sq ft is ~$10,200. Use per-square-foot math for your roof's size and the project range as a sanity check. Size, pitch, and complexity move every material's number more than the material choice itself.

Where the money goes: labor vs materials vs fees

• Labor$3,000–$12,000Tear-off crew, installers, flashing and underlayment. 40–60% of project cost; $40–$90/hr per worker (Angi). Steep/complex roofs add $1,000–$3,000.
• Roofing materials$2,500–$15,000Shingles or panels, underlayment, ice-and-water shield, flashing, ridge vent, fasteners. Biggest lever after roof size.
• Tear-off & disposal$1,000–$5,000Removing old layers, dumpster, haul-away. Multiple layers or heavy materials (tile, slate) cost more.
• Permits & decking repairs$500–$3,000Building permit ($250–$500, Angi) plus decking repairs found during tear-off — carry 10–15% contingency for decking.

2. Signs your roof needs replacing

Signs your roof needs replacing

• 20–25+ years old (asphalt) with visible aging. Past 20, every storm is a gamble — granule loss, curling, and brittleness accelerate together.
• Granules filling gutters and downspouts. The mineral armor is gone; exposed asphalt ages fast.
• Curling, cupping, or missing shingles across multiple slopes. Isolated damage is repairable; pattern failure means the system is done.
• Daylight through roof boards in the attic, or sagging deck between rafters. Structural warning — beyond shingles, can't wait.
• Recurring leaks in different spots, or stains spreading after ordinary rain. One leak is a repair; pattern leaks are system failure.

3. How a roof replacement works

How a roof replacement works

1. Inspection and itemized quote. Roofer measures (squares, pitch, penetrations), inspects the attic for ventilation and decking, discusses materials. You get an itemized quote: brand/line, underlayment, flashing, ventilation, tear-off, decking allowance, permits, timeline, warranty.
2. Delivery and site protection. Materials delivered (often craned up), dumpsters placed, landscaping tarped, permit posted. Verify delivered materials match the quote — brand, color, line — before tear-off.
3. Tear-off and decking repair. Old roofing off to the decking in sections to limit exposure. Decking inspected; rot replaced at the quoted per-sheet rate. The contingency moment — the 10–15% allowance exists for this.
4. Underlayment, flashing, installation. Ice-and-water shield at eaves/valleys, synthetic underlayment, drip edge, all-new flashing. Then the roofing material, nailed to manufacturer spec — nailing pattern sets both wind warranty and real wind resistance.
5. Ridge, cleanup, inspection. Ridge vent and cap, magnetic nail sweep of the yard (insist on it), gutter check, final inspection. Collect manufacturer warranty (registered), workmanship warranty, permit closure. File everything.

4. What affects the cost

Roof size: squares and pitch

Roofing's unit is the 'square' — 100 sq ft. A 1,700 sq ft roof is 17 squares; at $400–$900/square installed for asphalt, that's $6,800–$15,300 before complexity. Size dominates everything: doubling area roughly doubles cost. Measure footprint × pitch factor (6/12 pitch ≈ 12% more area than flat; 12/12 ≈ 41% more). Contractors who quote without measuring are guessing. A 12/12 pitch carries ~41% more area than a flat footprint — which is why two same-footprint homes can get very different quotes.

Material and cost per year of service

Architectural asphalt ($7,500–$18,000): 25–30 years, every contractor installs it. Standing-seam metal ($12,000–$25,000): 40–70 years — roughly double upfront, but compare cost per year of service: $12,000/25 yrs = $480/yr vs $22,000/60 yrs = $367/yr. Tile and slate are century materials with structural (weight) and specialized-labor requirements. Upfront price and lifetime value point opposite directions. The honest comparison is cost per year of service — where premium materials frequently win despite the higher upfront price.

Tear-off and decking contingency

Legally required in most jurisdictions at two existing layers, practically required otherwise: $1,000–$5,000 by layers, weight, and disposal fees. What tear-off reveals is the contingency — rotted decking ($50–$100/sheet), damaged fascia, poor ventilation. Carry 10–15% contingency for decking: $1,200–$1,800 on a $12,000 project. 'Decking extra at cost' with an allowance is honest; 'no surprises' on a 25-year-old roof is not.

Complexity: pitch, valleys, penetrations

Simple gable: cheapest. Steep pitches (above 7/12): +$1,000–$3,000 for safety gear and slower work (Angi). Valleys, dormers, skylights, chimneys: +$200–$500 each in flashing labor. Second stories add staging time. Cut-up roofs cost 30–50% more than simple gables of equal area — same shingle price, but cutting, flashing, and waste (10–15% vs 5%) compound. Your neighbor's $9,000 roof and your $14,000 roof can both be fair.

Underlayment, flashing, ventilation

Underlayment is the waterproofing beneath the visible roof — where cheap quotes cut corners. Synthetic ($0.30–$0.50/sq ft) beats felt ($0.15–$0.30) on strength and weight; always worth the small premium. Ice-and-water shield ($0.50–$1.00/sq ft): code at eaves in cold climates, cheap insurance in valleys everywhere. Flashing is the #1 leak source on re-roofs — insist on all-new flashing, never reused. A $1,500-cheaper quote reusing flashing isn't cheaper; it's a future leak.

Labor markets and crew quality

Roofing labor is 40–60% of the project ($40–$90/hr per worker, Angi); a typical asphalt job needs 4–6 crew for 1–3 days. High-cost metros run 25–40% above average; the Southeast and Midwest near or below. Crew quality is everything — roofing is a craft of details (flashing, nailing patterns, valleys) where workmanship, not shingles, separates a 25-year roof from a 12-year one. The established local roofer with a 10-year workmanship warranty beats the storm-chaser's low bid every time.

Permits, code, and HOAs

Permits run $250–$500 (Angi) and trigger inspection of nailing, flashing, underlayment, ventilation. Code upgrades vary: ice-and-water shield at eaves (cold climates), enhanced nailing in hurricane zones (Florida's code adds real cost and real wind resistance), cool-roof rules in parts of California. HOAs add architectural review and approved material lists. All of it belongs in the quote — a contractor who can't name your jurisdiction's roofing code is a risk.

Seasonal timing and price cycles

Late fall and winter (mild climates): 10–15% off-peak discounts, open schedules. Spring/summer: peak pricing. Post-storm emergency replacement: highest prices, zero leverage, crew shortages. Material prices move too — asphalt tracks petroleum, and post-hurricane demand has historically raised regional prices 10–20% for months. A roof at end of life but intact should be replaced in the off-season, not after the failure — cheaper, better contractor choice, less stress.

5. Saving money & hiring right

Questions to ask your contractor

• Itemize it: brand and product line, underlayment, flashing scope, ventilation, tear-off, decking allowance, permits — each on its own line?
• All flashing new, or reused? (Right answer: new — reused flashing is the top re-roof leak source.)
• Felt or synthetic underlayment — and where does ice-and-water shield go?
• Decking rate per sheet, and my allowance before change orders?
• Workmanship warranty in years, in writing — and how long at your current address?

6. How costs vary by state

Roofing follows local labor, storm exposure, and code. Planning ranges adjusting the $7,500–$24,000 band — confirm with local itemized quotes.
