Roof replacement is priced by the roof's measured area, the material, and the labor it takes to install it, not by one flat average. At $4 to $11 per square foot of roof area, most asphalt shingle replacements land between $9,000 and $18,000, with a national average near $9,500 according to Angi's 2026 data. A small, simple roof can stay near $6,000, a metal upgrade commonly runs $12,000 to $30,000, and tile or slate can reach $46,000 or more.
Labor makes up 50 to 60 percent of the total, which is why two identical shingle packages can be quoted thousands of dollars apart. Steep or complex roofs add 10 to 25 percent to labor, and slopes above a 7/12 pitch can add even more once harnesses and staging are required. The other wildcard is decking: rotted plywood is replaced per sheet at $60 to $100, and it only becomes visible after tear-off, so a reliable quote states that per-sheet price up front.
Replacement is worth scheduling when the roof is at the end of its lifespan, when leaks have reached the interior, or when storm damage spans whole slopes, since insurance may cover that last case minus your deductible. Because quotes for the same roof routinely differ by thousands, get at least three bids, make sure each one is a full tear-off with the same underlayment and flashing scope, and treat any driveway diagnosis with skepticism.
Ask every roofer for the same three numbers: the measured roof area in squares, the per-sheet price for decking replacement, and what the workmanship warranty covers separately from the shingle manufacturer's warranty. Quotes that hide any of these are the ones most likely to grow mid-project.
Roof replacement cost by material
Material is the biggest single price lever after roof size. These installed prices include tear-off, underlayment, and labor. One roofing square covers 100 square feet, so a 2,000 square foot roof is 20 squares.
| Material or component | Installed cost | What to know |
|---|---|---|
| 3-tab asphalt shingles | $4.50 to $7.50 per sq ft | The budget option; flat appearance and a 15 to 20 year lifespan |
| Architectural asphalt shingles | $6 to $9 per sq ft | The most common choice; dimensional look and a 20 to 30 year lifespan |
| Corrugated or ribbed metal panels | $6 to $8 per sq ft | The most affordable metal; common on simpler rooflines |
| Metal shingles | $7.50 to $10.50 per sq ft | Metal durability with a shingle look; 40 to 70 year lifespan |
| Standing seam metal | $18 to $24.50 per sq ft | Premium concealed-fastener metal; the top of the metal range |
| Concrete or clay tile | $10 to $18 per sq ft | 50 to 100 year lifespan; the structure must carry the extra weight |
| Natural slate | $20 to $40 per sq ft | The premium tier; often requires structural reinforcement |
| Decking replacement | $60 to $100 per 4x8 sheet | Scoped after tear-off; partial replacements often total $1,400 to $2,500 |
| Permit fees | $70 to $250 in most areas | Higher in some jurisdictions; confirm who pulls and pays in the quote |
Tear-off and disposal run $1 to $5 per square foot and should already be inside the installed prices above. If a quote lists tear-off as an extra on top of a per-square-foot installed price, ask why before comparing it against other bids.
Signs your roof needs replacement
Roofs rarely fail all at once. A pattern of these signs, especially on a roof past 15 years, is worth an inspection before the next storm season turns wear into water damage.
Not every leak means a new roof. A flashing failure around a chimney or a single damaged slope on a mid-life roof is usually a repair, not a replacement. The honest dividing lines are age, how widespread the damage is, and whether the decking underneath is still sound, which is exactly what a real inspection establishes.
What drives roof replacement cost
Roof size sets the baseline, but material, pitch, and what tear-off reveals are what separate a $9,000 project from a $25,000 one.
Roof size and squares
Roofers price by the square, which is 100 square feet of roof area. At $4 to $11 per square foot, a 1,700 square foot roof runs roughly $7,000 to $19,000 depending on material, and a 2,500 square foot roof scales up proportionally. Roof area runs larger than the home's footprint because of pitch and overhangs, which is why a measured roof, not the home's listed square footage, is the starting point for any real quote.
Material choice
Architectural asphalt at $6 to $9 per square foot is the default for most homes. Stepping down to 3-tab saves 15 to 20 percent up front but gives up a decade of lifespan. Stepping up to metal, tile, or slate can double or quadruple the price while extending the roof's life to 40 years or more, which changes the math if you plan to stay in the home long-term.
Pitch, complexity, and stories
Labor is 50 to 60 percent of a roof replacement, so anything that slows the crew raises the price. Steep roofs at a 6/12 pitch or above add 10 to 25 percent to labor, and slopes past 7/12 can add more once harnesses and staging are required. Valleys, dormers, skylights, and chimneys each add flashing work, and a second or third story slows material handling.
Tear-off layers and decking condition
A full tear-off down to the decking is standard, and removal runs $1 to $5 per square foot, more for heavy materials or a second shingle layer. What tear-off reveals is the most common surprise cost: rotted decking is replaced per 4x8 sheet at $60 to $100, and partial replacements commonly total $1,400 to $2,500. A quote that states the per-sheet price up front turns that surprise into arithmetic.
Labor market, season, and permits
Roofing labor runs $40 to $90 per hour per worker and varies sharply by region, which is why the same shingle package prices differently across markets. Demand spikes after major storms and in late summer can stretch schedules and firm up prices. Permits add $70 to $250 in most areas, more in high-fee jurisdictions, and the quote should say who pulls and pays for them.
When roof replacement is usually worth completing
A roof protects everything under it, so replacement is often worth the cost when waiting puts the structure, the interior, or your insurance coverage at risk.
- The roof is at the end of its rated lifespan and repairs are becoming a yearly event.
- Leaks have reached the interior, since water damage to decking, insulation, and drywall compounds with every rain.
- Storm damage spans whole slopes and an insurance claim, minus your deductible, may fund most of the project.
- Your insurer has flagged the roof's age, since many carriers limit or drop coverage on roofs past 20 years.
- You are selling soon, where an aging roof becomes a negotiation point that often costs more than the replacement.
When to pause before signing a roofing contract
Roofing attracts more door-to-door and storm-chasing sales than almost any other trade. These situations call for a second opinion before you commit.
- The diagnosis happened from the driveway, since no one can scope a roof without getting on it and into the attic.
- A contractor appeared unsolicited after a storm and wants you to sign over your insurance claim on the spot.
- The leak is isolated to flashing or one slope on a mid-life roof, where a repair may buy years for a fraction of the price.
- The quote omits the per-sheet decking price, the underlayment type, or what happens when hidden damage is found.
- You are pressured to sign today or pay a large deposit before any written scope exists. Get at least three bids.
Estimate your roof replacement cost
Use the calculator as a planning range before requesting quotes. Adjust the roof area, material, pitch, and decking condition to see how the estimate shifts. The real number depends on a measured roof and an inspection that confirms layers and decking.

How we built these ranges and our sources
These figures are planning ranges, not quotes. We cross-checked per-square-foot pricing, material tiers, and component costs against multiple independent 2026 home-services pricing references, then framed them around the scopes roofers actually quote. The primary sources behind this guide include:
- Angi, How Much Does Roof Replacement Cost (2026 data) for national averages and the project range
- NerdWallet, Roof Replacement Cost in 2026 for typical ranges and labor share
- This Old House and HomeGuide for cost by roof size and material lifespans
- Fixr and Homewyse for per-square-foot material and labor pricing
- Progressive, Allstate, and the Texas Department of Insurance for roof insurance coverage rules
- Pricing is reviewed and updated as sources change; see the linked methodology for how ranges are constructed.
