Roof replacement cost guide: materials, insurance and real prices
Most US homeowners pay $9,000 to $16,000 for a full roof replacement in 2026, based on 2,000 sq ft of roof surface (20 roofing squares) finished in architectural asphalt shingles. A small three-tab job can come in around $7,000, while a large roof in a premium material such as slate can reach $60,000 or more.
A new roof is one of the largest bills a homeowner ever pays. This guide explains what a replacement really costs, how roofers actually measure and price the job, what moves the number up or down, how insurance and financing fit in, and how to avoid overpaying.

Key takeaways
The number
A typical architectural shingle replacement costs $9,000 to $16,000 on 2,000 sq ft of roof surface, which is 20 roofing squares.
Roof, not house
Roofs are priced on roof surface area, not house square footage. A 2,000 sq ft house usually has 2,200 to 2,600 sq ft of roof once pitch is counted.
Material
Material is the single biggest lever on both price and lifespan, from three-tab shingles at 12 to 18 years to slate at 75 years or more.
Labor
Labor typically makes up 40 to 60 percent of the installed price, which is why identical materials can produce very different quotes.
Complexity
Steep pitch or a complex roofline can each add 20 to 40 percent. A second old layer, difficult access, and post-storm demand add more.
Location
Where you live changes both the price and what the code requires, especially in hurricane, hail, wildfire, and cold-climate regions.
the baseline
Average roof replacement cost in 2026
For a standard asphalt shingle roof, most homeowners pay $9,000 to $16,000 for a full replacement. Every figure below uses the same reference roof: 2,000 sq ft of roof surface, 20 roofing squares, one existing layer removed, at a moderate pitch.
Roof replacement cost by budget level, on the 20-square reference roof:
| Budget level | Typical material | What you will pay |
|---|---|---|
| Lowest cost | Three-tab asphalt shingle | $7,000–$11,000 |
| Most common | Architectural asphalt shingle, the default on most US homes | $9,000–$16,000 |
| Mid to upper | Class 4 impact-resistant shingle or metal | $10,000–$32,000 |
| Premium | Tile or slate | $20,000–$60,000 |
Included in these prices: tearing off one existing layer, hauling it away, new synthetic underlayment, drip edge, flashing, ridge cap and ridge vent, labor, and permit coordination. Not included: new decking, structural repairs, skylights, chimney work, and gutters, because none of those can be priced until the old roof is off.

Why the numbers online disagree
Why published roof prices disagree so much
Published roof prices range from around $7,000 to $60,000 for what looks like the same job. That is rarely because roofers are dishonest. It is usually because the prices are measured in different ways and then compared as if they were the same thing.
Roof surface confused with house footprint.
Many sites multiply a per-square-foot price by a home's floor area. But a roof is always larger than the floor beneath it, because pitch adds surface. This single mistake causes more bad estimates than anything else.
No pitch adjustment.
Roofers use a pitch multiplier to convert footprint into true roof area. A 6/12 roof, one that rises 6 inches for every 12 inches it runs, is about 1.12 times its footprint. Skip this step and the estimate is wrong before material prices are even applied.
Square feet instead of squares.
Contractors price in roofing squares, where one square is 100 sq ft of roof. A 2,000 sq ft roof is 20 squares. A price guide that never mentions squares was probably not written from real trade pricing.
Every asphalt shingle lumped together.
A basic three-tab shingle and a Class 4 impact-resistant shingle are both asphalt, yet the installed price of the premium grade can run close to double the budget one.
Different scopes of work.
Some prices are materials only. Others include tear-off, disposal, and labor. Some include a waste factor and some do not. None of that shows up in a single headline figure.
Every price in this guide uses one consistent scope, so the comparisons hold up: 20 squares, one existing layer removed, moderate pitch, installed.
the maths
How roofers measure a roof
Contractors turn your home's footprint into a real roof size in two steps: multiply the footprint by a pitch multiplier to get roof surface area, then add a waste factor to work out how much material to order.
Step 1: apply a pitch multiplier
Pitch multipliers. Roof surface = footprint (including overhangs) × multiplier.
| Roof pitch | Pitch multiplier | Extra area over footprint |
|---|---|---|
| Low slope, 3/12 to 4/12 | 1.03–1.06 | 3 to 6 percent |
| Moderate slope, 5/12 to 7/12 | 1.08–1.16 | 8 to 16 percent |
| Steep slope, 8/12 to 12/12 | 1.20–1.41 | 20 to 41 percent |
Step 2: add a waste factor for material ordering
Typical waste factors, used to calculate how much material to order
| Roof type | Waste factor |
|---|---|
| Simple gable roof | About 10% |
| Complex roof with hips, valleys, and dormers | 15–20% |
Worked example.
A home with a 2,000 sq ft footprint and a 6/12 pitch has about 2,000 × 1.12 = 2,240 sq ft of roof surface, or 22.4 squares. With a moderately complex roofline and a 15 percent waste factor, the contractor orders roughly 2,240 × 1.15 ≈ 2,576 sq ft of material, nearly 26 squares, not the 20 the footprint alone suggests.
Do not count waste twice
The installed per-square-foot prices in this guide already include normal waste. To estimate cost, multiply them by your roof surface area (2,240 sq ft in the example), not by the material quantity. In the example, architectural shingles at $4.50 to $8.00 would put the job at roughly $10,080 to $17,920. Multiplying by the 2,576 sq ft of material instead would overstate it by about 15 percent.
by size
Roof replacement cost by roof size
An architectural shingle roof costs roughly $4.50 to $8.00 per square foot of roof surface installed. That puts a 1,500 sq ft roof at about $6,750 to $12,000 and a 3,000 sq ft roof at about $13,500 to $24,000.
Architectural asphalt shingle, by square feet of ROOF SURFACE (not house size)
| Roof surface | Roofing squares | Estimated cost |
|---|---|---|
| 1,000 sq ft | 10 | $4,500–$8,000* |
| 1,500 sq ft | 15 | $6,750–$12,000 |
| 2,000 sq ft | 20 | $9,000–$16,000 |
| 2,500 sq ft | 25 | $11,250–$20,000 |
| 3,000 sq ft | 30 | $13,500–$24,000 |
Why small roofs cost more per square foot
Setup, the dumpster, the permit, and crew mobilization cost roughly the same whether the roof is 10 squares or 30. On small roofs those fixed costs are spread over less area, so expect the upper end of the 1,000 sq ft range or above it. Many contractors also set a minimum job charge. Larger roofs tend toward the lower per-square-foot end, though the total is still higher.

by material
Roof cost by material, at a glance
Material sets both today's price and how many years pass before you pay again. Three-tab asphalt starts around $3.50 per square foot installed and lasts 12 to 18 years; slate runs $15 to $30 and can last 75 to 100 years.
Installed cost per square foot of roof surface, and total on 20 squares. National ranges.
| Material | Per sq ft installed | Total, 20 squares | Typical lifespan |
|---|---|---|---|
| Three-tab asphalt shingle | $3.50–$5.50 | $7,000–$11,000 | 12–18 years |
| Architectural asphalt shingle | $4.50–$8.00 | $9,000–$16,000 | 15–25 years |
| Class 4 impact-resistant shingle | $5.00–$9.00 | $10,000–$18,000 | 20–30 years |
| Exposed fastener metal panels | $7.00–$12.00 | $14,000–$24,000 | 25–40 years |
| Standing seam metal | $9.00–$16.00 | $18,000–$32,000 | 40–60 years |
| Concrete tile | $10.00–$19.00 | $20,000–$38,000 | 30–50 years |
| Clay tile | $12.00–$22.00 | $24,000–$44,000 | 40–60 years |
| Slate | $15.00–$30.00 | $30,000–$60,000 | 75–100 years |
| Flat or low-slope membrane | $5.00–$12.00 | $10,000–$24,000 | 15–25 years |
Asphalt shingles are the cheapest upfront, which is why they cover most US homes. If you plan to stay 20 years or more, a longer-lived material can cost less per year of service: a $9,000 architectural roof lasting 20 years costs about $450 a year, while a $24,000 standing seam roof lasting 50 years costs about $480, with far fewer replacements along the way. Reflective metal can also reduce summer cooling load in hot climates.

cost drives
What moves your roof replacement cost
Two roofs with the same shingles and the same 20 squares can still land thousands of dollars apart. Pitch, complexity, existing layers, access, timing, and the condition of the decking underneath decide where your job falls in the range.
Common cost modifiers, applied on top of the base price
| Factor | Typical effect | Why |
|---|---|---|
| Steep pitch, 8/12 or steeper | +20–40% | Harnesses, roof jacks, and slower, more careful installation |
| Complex roofline | +20–40% | More planes mean more valleys, flashing, cutting, and labor than a simple gable |
| A second existing layer | +$1.00–$2.00 / sq ft | Twice the material to strip and dispose of |
| Two storeys or difficult access | +10–20% | Getting crew and materials up safely takes longer |
| Right after a major storm | +10–25% | Demand spikes for roughly 60 to 90 days and materials get harder to source |
| Damaged decking | $70–$150 per sheet | Rotted 4 by 8 sheathing is replaced sheet by sheet, found only after tear-off |
None of these should be a surprise if a contractor explains them upfront. Each belongs on your quote as a visible line item, not folded quietly into one larger number.

What a complete roof replacement quote should include
A trustworthy quote lists each part of the job separately instead of giving one flat total. If a line below is missing, ask whether it is included, priced elsewhere, or being skipped.
Line items in a complete residential roof replacement quote
| Item | What it covers | What to look for |
|---|---|---|
| Tear-off | Removing the old roof down to the decking | Typically $50–$150 per square |
| Decking or sheathing | The wooden boards under everything else | A per-sheet price, never an open-ended lump sum |
| Underlayment | Waterproof layer between decking and shingles | Synthetic as standard; self-adhering modified bitumen as an upgrade |
| Ice and water shield | Sealed membrane at eaves and valleys that stops ice dams | Required by the residential code where ice dams are a known problem |
| Drip edge | Metal strip guiding water off the roof edge into the gutter | Required by code on asphalt shingle roofs; often missing from low bids |
| Flashing | Metal sealing joins at walls, chimneys, and valleys | Step flashing, counter flashing, and pipe boots; most leaks start here |
| Starter strip | Adhesive first course along eaves and rakes | Often skipped by budget crews; prevents wind lift at the edges |
| Fasteners | How shingles are nailed down | Nail count per shingle per the manufacturer; ring-shank nails hold better than smooth shank in high wind; hot-dip galvanized resists corrosion better than electro-galvanized near the coast |
| Valleys | Where two roof planes meet and water concentrates | Open metal valley or closed-cut valley, stated in writing |
| Ridge cap and ridge vent | Caps the peak and lets hot attic air out | Proper ridge cap shingles, not cut-down field shingles |
| Soffit or intake vents | Let cool air in to balance the ridge vent | Exhaust without intake does little; ventilation should be balanced |
| Other ventilation | Static box vents, powered or solar attic fans | Used when ridge and soffit alone cannot achieve balanced airflow |
| Disposal and cleanup | Dumpster, hauling, and a magnetic nail sweep of the yard | Itemized, not buried in labor |
| Permit | Securing and closing out the local permit | The contractor should pull it; fees vary by municipality |
Usually not included: gutters, skylights, chimney rebuilding, and structural repairs.
Two warranties, not one
Manufacturer material warranty
Covers defects in the shingles or other materials. Major manufacturers such as GAF, CertainTeed, Owens Corning, and TAMKO commonly offer long or "limited lifetime" terms on architectural shingles, but coverage is often prorated after an initial period, so read what "lifetime" actually means.
Workmanship warranty
Provided by the installer and covers installation errors, commonly 2 to 10 years. This is the one that protects you against a bad install. Some manufacturers offer enhanced system warranties that also cover workmanship when a certified contractor installs a complete system.
Compare what the calculator suggests with your contractor quotes to spot missing line items before they become change orders.
labor
Labor costs, explained
Labor typically makes up 40 to 60 percent of the installed price, often more than the shingles themselves. Roofing is physically demanding, seasonal, skilled work with real safety risks, and the price reflects that.
What drives the labor portion of a quote
| Factor | Effect on labor |
|---|---|
| Roof size | More squares means more crew hours and a higher labor total |
| Pitch and complexity | Steep or cut-up roofs take longer; typically 20 to 40 percent more |
| Tear-off difficulty | Extra layers or brittle old shingles slow removal |
| Crew model | In-house employees against subcontracted crews can affect price and consistency |
| Pricing method | Most residential jobs are priced per square; some crews charge per day |
| Site access | Hard-to-reach roofs and tight lots add time |
According to the U.S. Bureau of Labor Statistics, the median annual wage for roofers was $55,440 in May 2025, and employment is projected to grow 5 percent from 2025 to 2035, faster than average, with about 12,000 openings a year. Steady demand for a limited skilled workforce is a large part of why labor costs hold firm even when material prices move.
Labor against everything else
On the reference roof, labor at 40 to 60 percent of a $9,000 to $16,000 job works out to roughly $3,600 to $9,600. The remainder covers materials, disposal, the permit, and the contractor's overhead and profit. Where your job falls depends on pitch, complexity, and access, which is why two quotes using identical materials can differ by thousands.
location
How your home's location changes the price
The figures above are a national baseline. Where you live shifts the price mainly because local building codes respond to wind, hail, wildfire, and cold, which changes what must be installed, and secondarily because labor rates differ.
Coastal and hurricane regions
Stricter fastening, higher wind-rated products, and in some states product approvals, sometimes well inland of the coast. South Florida's High Velocity Hurricane Zone has the strictest roofing code in the country, including a secondary water barrier, an extra sealed layer beneath the roof covering that is easy to miss on a quote.
Hail-prone states
Where Class 4 impact-resistant shingles most clearly pay for themselves, both in durability and in insurance discounts tied to the UL 2218 rating.
Wildfire-prone regions
Parts of California and Colorado require Class A fire-rated roof assemblies, the highest fire rating, plus ember-resistant venting.
Cold and northern climates
Snow load built into the structure, and ice and water shield at the eaves to stop ice dams damaging a new roof.
Generally more expensive: Hawaii, Alaska, and high labor cost states such as California, New York, Massachusetts, Connecticut, New Jersey, and Washington. Generally less expensive: lower-cost Southern states such as Alabama, Mississippi, Arkansas, Kentucky, and West Virginia, though hail- and hurricane-exposed areas within cheaper states can still run high because of material requirements.
Stack whichever of these applies on top of the pitch, complexity, and access factors above to get a realistic figure for your home. For state-specific costs, codes, and insurance rules:
insurance
Will insurance pay for a new roof?
Homeowners insurance typically pays when roof damage is sudden and accidental, such as hail, wind, fire, or a fallen tree. It does not pay for wear from age, neglect, or lack of maintenance. How much it pays depends on your policy terms as much as on the damage.
If you think you have storm damage
- Photograph the damage, inside and out, before any repairs.
- Make temporary repairs to prevent further damage, and keep the receipts.
- Get an independent roof inspection, not only the adjuster's assessment.
- Report the claim promptly. Policies require timely notice and set deadlines to file, and some states set limits of their own, so check yours.
- Get contractor quotes before agreeing to the insurer's settlement figure. If the contractor later finds damage the adjuster missed, a supplement can be filed.
The policy terms that decide your payout
Actual cash value against replacement cost value
ACV pays the depreciated value of your old roof, which can leave a large gap on an older roof. RCV pays to replace it new, often in two stages: the depreciated amount first, and the held-back recoverable depreciation once the work is done.
Roof payment schedules
Some policies pay a declining percentage of roof cost as the roof ages, even when the rest of the home is covered at replacement cost. Look in the endorsements, not just the declarations page.
Percentage deductibles
Wind and hail deductibles are often a percentage of dwelling coverage. At 2 percent on $400,000 of coverage, you pay the first $8,000 yourself.
Cosmetic damage exclusions
Exclude hail damage that dents the surface without affecting how the roof sheds water. Common in hail states, sometimes as a condition of a Class 4 discount.

paying for it
Tax credits and financing
There is no federal tax credit for a new roof installed in 2026. Financing, and insurance where storm damage is involved, are the realistic ways most homeowners spread the cost.
The federal credits ended at the close of 2025
Standard roofing, including reflective "cool" roofs, stopped qualifying for the Section 25C energy efficient home improvement credit after the Inflation Reduction Act changes took effect in 2023. The One Big Beautiful Bill Act then ended both Section 25C and the Section 25D residential clean energy credit for property installed after 31 December 2025. That includes solar shingles and solar tiles you own: if installation was completed in 2026, the 30 percent federal credit does not apply. Check IRS.gov or a tax professional before assuming any credit, and ask about state or utility incentives, which are separate.
Financing options
| Option | Best for | Watch out for |
|---|---|---|
| Home equity loan or HELOC | Homeowners with equity; usually the lowest rate | Your home secures the loan; closing costs and time to fund |
| Contractor financing | Convenience at the point of sale | Promotional "no interest" plans are often deferred interest, charging all back interest if not paid off in time |
| Personal loan | Speed, no collateral | Higher rates, especially with weaker credit |
| FHA Title I property improvement loan | Borrowers with limited equity | Loan limits and lender availability vary |
| PACE financing | Qualifying energy upgrades in the few states that allow it | Repaid through your property tax bill as a lien, which can complicate a sale or refinance |
| Insurance claim | Storm, hail, wind, or fire damage | Deductibles and depreciation; see the insurance section |
Compare rates from several lenders before committing, since terms vary widely by state and credit profile. This is general information, not financial advice. See
roof financing options in full, or
roof financing with bad credit.
the decision
Repair or replace?
You do not always need a full replacement. Localized damage on a younger roof is usually a repair. Widespread wear on a roof near the end of its life is usually a replacement, because repeated repairs end up costing more than they save.
Repair is probably enough if
- Damage is localized: one leak, a failed pipe boot, a handful of missing shingles
- The roof is well within its expected lifespan
- There is no sagging, soft decking, or widespread granule loss
Replacement is probably smarter if
- The roof is near or past its material's expected lifespan
- There are multiple leaks or soft spots in the decking
- Shingles are curling, cracking, or bald across large areas
- You are selling and want to avoid inspection objections
Repairs typically cost a small fraction of a replacement, but they are only a short-term fix on a roof that is already near the end. One more point worth knowing: in some states, repair rules in the building code can force a larger area to be brought up to current code once damage passes a threshold. Florida's 25 percent rule is the best known example. Work through the decision in detail in roof repair vs replacement.

Red flags, especially after a storm
Door-to-door crews offering free inspections, pressure to sign the same day, requests for a large deposit before materials arrive, and any offer to cover, waive, or rebate your insurance deductible. That last one is illegal in several states, including Colorado and Texas, and can put your claim at risk. Be cautious too with any contract that assigns your insurance benefits to the contractor.

timing
When to replace a roof, and how long it takes
A typical single-storey architectural shingle roof takes 1 to 3 days from tear-off to finish. Larger homes, steep pitches, and tile or slate can take a week or more, and weather delays can stretch any job.
Mild, dry weather suits installation best, because shingles need warmth to seal properly and crews will not work in rain or high wind. That makes late spring and early fall popular, which also means the busiest scheduling. In colder months crews may have more availability, but shingles may need hand-sealing to bond. The most expensive time is usually the weeks right after a major storm, when demand spikes. If your roof is leaking, though, do not wait for a better season.
plain english
Roofing terms, explained
You will meet these terms on quotes, insurance paperwork, and inspection reports. Knowing them makes it far easier to compare contractors and question a scope.

| Pitch | Roof steepness as rise over run; 6/12 rises 6 inches per 12 inches. |
| Pitch multiplier | The factor converting footprint to true roof area. |
| Waste factor | Extra material ordered for cuts and offcuts, usually 10 to 20 percent. |
| Decking or sheathing | The plywood or OSB boards the roof is built on. |
| Underlayment | The water-resistant layer between the decking and the roof covering. |
| Ice and water shield | Self-adhering membrane at eaves and valleys that stops ice dam leaks. |

| Flashing | Metal sealing the joins at walls, chimneys, valleys, and penetrations. |
| Valley | The internal angle where two roof planes meet. |
| Ridge vent | Exhaust vent along the peak that lets hot attic air escape. |
| Tear-off | Removing the old roof down to the decking. |
| Overlay or re-cover | New shingles over the old; the code generally allows two layers at most. |
| Class 4 impact rating | The top UL 2218 hail-impact rating for roofing. |
| Class A fire rating | The highest fire resistance rating for a roof assembly. |
| ACV and RCV | Actual cash value pays depreciated value; replacement cost value pays to replace new. |
| Recoverable depreciation | The part of an RCV claim held back until the work is finished. |
| Supplement | An additional claim for damage found after the original estimate. |
QUICK ANSWERS
Frequently asked questions
How much does a new roof cost on average?
Most homeowners pay $9,000 to $16,000 for a full replacement using architectural asphalt shingles on 2,000 sq ft of roof surface, which is 20 roofing squares. Three-tab shingles can come in around $7,000, while tile or slate on the same roof can reach $20,000 to $60,000.
How much does a roof cost per square foot?
Architectural asphalt shingles cost about $4.50 to $8.00 per square foot of roof surface installed. Metal runs about $7.00 to $16.00, tile $10.00 to $22.00, and slate $15.00 to $30.00. Price per square foot applies to roof surface, which is larger than your home's floor area once pitch is counted.
Which roofing material lasts the longest?
Slate lasts longest, commonly 75 to 100 years, followed by clay tile at 40 to 60 years and standing seam metal at 40 to 60 years. Architectural asphalt shingles typically last 15 to 25 years. Longer-lived materials cost more upfront but can cost less per year of service.
Will insurance pay for my new roof?
Insurance usually pays for sudden damage from covered events such as hail, wind, fire, or falling trees, not wear from age or neglect. Whether you receive the depreciated value or full replacement cost depends on whether your policy settles the roof at actual cash value or replacement cost, and on your deductible.
Is there a tax credit for a new roof in 2026?
No federal credit applies to a roof installed in 2026. Standard roofing stopped qualifying for Section 25C after 2022, and the One Big Beautiful Bill Act ended both Section 25C and the Section 25D solar credit for property installed after 31 December 2025, including owned solar shingles. State or utility incentives may still exist.
Can I replace my roof myself?
Technically yes, but it is rarely a good idea. DIY roofing carries real fall risk, gives you no workmanship warranty, and can void the manufacturer's material warranty if the installation does not meet specification. A failed DIY install often costs more to fix than hiring a licensed crew would have.
What is the difference between an overlay and a full tear-off?
An overlay installs new shingles over the existing layer; a tear-off strips the roof to the decking first. Overlays cost less upfront but hide decking damage, trap heat, and can shorten shingle life. The residential building code generally prohibits a new overlay where two layers already exist, so a roof with an existing overlay needs a full tear-off.
How long does a roof replacement take?
A typical single-storey roof with architectural shingles takes 1 to 3 days. Larger homes, steep pitches, and premium materials such as tile or slate can take a week or longer, and rain, high wind, or cold can pause work, since shingles need dry, warm conditions to seal properly.
Are there hidden costs in a roofing quote?
The most common are replacing rotten decking found after tear-off, removing a second existing layer, upgraded flashing or ventilation, and permit fees. A trustworthy contractor prices decking per sheet and lists each item upfront rather than surprising you mid-project.
Should I get multiple quotes?
Yes. Get at least three written, itemized quotes from licensed and insured contractors. Prices for the same roof commonly vary by thousands of dollars, and comparing line items side by side is the easiest way to spot a padded quote or one that is missing key work.
Can I finance a roof replacement?
Yes. Common options include home equity loans and HELOCs, personal loans, contractor financing, FHA Title I property improvement loans, and in a few states PACE financing. Check insurance first if there is storm damage, and read promotional financing terms carefully, since many are deferred interest.
how we built this
How these figures are built
Every price on this page uses one reference job, 2,000 sq ft of roof surface (20 squares), one existing layer removed, moderate pitch, installed, so the numbers can be compared with each other and with the rest of this site. They are national planning ranges reconciled from published contractor pricing and manufacturer information, not quotes. Your actual cost depends on your roof, your region, and what is found under the old roof.

These are planning estimates, not quotes. No online tool can assess your roof deck, ventilation, or local permit requirements. Only a licensed contractor who has inspected your roof can give you a firm price. Insurance, tax, and financing information is general, current as of the review date, and not legal, tax, or financial advice. Verify specifics with your insurer, lender, or a tax professional before acting.
