Key takeaways
- Most homeowners pay $8,000–$16,000, or $350–$750 per roofing square for asphalt.
- Your roof is not the same size as your house — pitch and overhangs add 5–40%.
- Labor is 40–60% of the bill and swings the total more than any other factor.
- Asphalt recoups about 61% at resale — the best of any roofing material.
- Never compare bottom-line totals. Compare the square count and price per square.

What a roof replacement actually costs
The honest answer is that a "national average" tells you very little. A 20-square asphalt roof in Mississippi and the same roof in Massachusetts are separated by thousands of dollars, and nothing about the roof changed — only the wages of the people installing it.
What follows is the range most homeowners land in, and then the four things that actually move your number within it.
Roof replacement cost by home size
Architectural asphalt shingles, 6/12 pitch, including tear-off and disposal.
| Home size | Roof area | Squares | Typical cost |
|---|---|---|---|
| 1,000 sq ft | ~1,150 sq ft | 11–13 | $4,500 – $9,000 |
| 1,500 sq ft | ~1,700 sq ft | 16–19 | $6,500 – $13,000 |
| 2,000 sq ft Most common | ~2,300 sq ft | 22–26 | $9,000 – $18,000 |
| 2,500 sq ft | ~2,900 sq ft | 27–32 | $11,500 – $23,000 |
| 3,000 sq ft | ~3,450 sq ft | 33–38 | $14,000 – $28,000 |
Roof area exceeds floor area because of pitch and overhangs. A steeper roof widens these ranges considerably — a 12/12 pitch adds 41% more surface than the footprint beneath it.
The mistake almost everyone makes
A 2,000 sq ft house does not have a 2,000 sq ft roof. Pitch and overhangs add 5–40% more surface. If a contractor quotes you from your home's listed square footage without measuring, they are guessing — and that tells you something about how carefully they will do the rest of the job.
Cost by roofing material
Material is the biggest lever you actually control. But comparing sticker prices is a trap: a material that costs half as much and lasts a third as long is not cheaper. Divide by lifespan before you decide anything.
Installed cost, lifespan and cost per year
Based on a 23-square roof — a typical 2,000 sq ft home.
| Material | Per square | Total (23 sq) | Lifespan | Cost per year |
|---|---|---|---|---|
| Asphalt (3-tab) | $350 – $550 | $8,000 – $12,650 | 15–20 yrs | ~$590 |
| Asphalt (architectural) Most common | $450 – $750 | $10,350 – $17,250 | 20–30 yrs | ~$480 |
| Wood shake | $650 – $950 | $14,950 – $21,850 | 25–40 yrs | ~$570 |
| Metal (standing seam) | $900 – $1,600 | $20,700 – $36,800 | 40–70 yrs | ~$400 |
| Tile (clay/concrete) | $1,000 – $2,000 | $23,000 – $46,000 | 50–75 yrs | ~$450 |
| Slate | $1,500 – $3,000 | $34,500 – $69,000 | 75–100 yrs | ~$490 |
Cost per year uses the midpoint of each range. Note that metal — the "expensive" option — has the lowest annual cost of any material here. Whether that matters depends entirely on how long you plan to stay in the house.
The staying-put test
Metal only wins if you are there to collect the benefit. Over 60 years it is the cheapest roof on this table. Over 8 years, you have paid a large premium and will recoup roughly 49% of it at resale — less than asphalt's 61%. The question is not "which roof is best?" but "how long am I staying?"
Where the money actually goes
Most homeowners assume materials dominate the bill. They don't. On a typical asphalt replacement, labor is the single largest line — and it is the line that explains why two quotes for the same roof can differ by thousands.
Typical breakdown — $13,000 asphalt replacement
| Line item | Share | Typical cost |
|---|---|---|
| Installation labor Most common | 40–60% | $5,200 – $7,800 |
| Materials (shingles, underlayment, nails) | 30–40% | $3,900 – $5,200 |
| Tear-off & disposal | 8–12% | $1,000 – $1,600 |
| Permit | 2–5% | $250 – $700 |
| Sales tax (on materials) | 0–8% | Varies by state |
Labor tracks local wages, which is why we price it from published BLS wage data for your specific state rather than a national average that applies to nobody.
Use this when you compare bids
Materials cost roughly the same for every contractor in your town — they buy from the same suppliers. So when two bids differ by $4,000, it is almost never the shingles. It is labor, overhead, or something one of them left out of the scope. Ask which.
Why your state changes everything
Roofing labor runs from roughly $130 per square in Mississippi to $265 in Hawaii — a difference of more than 2×. On a 23-square roof that alone is a swing of over $3,000, before a single shingle is chosen.
This is the reason we do not publish a single national average and call it a day. We price labor from published BLS occupational wage data for all 50 states, then adjust it for your pitch, your building height and your job complexity.
Roofing labor cost per square, selected states
| State | Labor per square | vs national average |
|---|---|---|
| Hawaii | $265 | +42% |
| California | $255 | +37% |
| New York | $250 | +34% |
| Massachusetts | $248 | +33% |
| National average Most common | $186 | — |
| Texas | $165 | −11% |
| Alabama | $145 | −22% |
| Mississippi | $132 | −29% |
The calculator applies your state's figure automatically. Labor is the single largest variable in any roofing quote.
Should you repair instead?
Replacement is not always the right answer, and any contractor who reaches that conclusion within ninety seconds of arriving deserves a second opinion. Three tests decide it.
-
1
Is the damage localised?
A single leak around a chimney is a flashing repair. Widespread curling, cupping or granule loss across the whole roof is not — that is a roof at the end of its life.
-
2
How old is the roof?
Past two-thirds of the material's expected life — roughly 17+ years for asphalt — repairs start throwing good money after bad. You will be back next winter.
-
3
Does the repair exceed 30% of a replacement?
If yes, replace. You are paying a third of the price to delay the decision by a year or two, and you will pay the full price anyway.
Check insurance before you do either
If a storm, hail or a fallen tree caused the damage, your policy may cover replacement minus the deductible. Age and ordinary wear are never covered. Photograph everything before anyone touches the roof, and file before your deadline — often 12 months from the date of damage.
How to actually save money
Not "get three quotes" — everyone says that and it is nearly useless advice on its own, because most homeowners then compare three bottom-line numbers that measure different roofs. Here is what works.
-
1
Make the quotes comparable
Insist every bid states the square count and the price per square. Two contractors both saying "$14,000" may be measuring roofs that differ by 20%. Without the square count you are comparing nothing at all.
-
2
Book in the off-season
Roofing demand peaks in late summer and immediately after storms. A crew with an empty February calendar negotiates; a crew three months deep in hail work does not.
-
3
Bundle the gutters and fascia
They are already exposed during a tear-off and the crew is already there. Doing them later means paying a second mobilisation.
-
4
Pin the decking price up front
The single most effective clause you can add to a roofing contract: a written per-sheet price for replacement decking, agreed before anyone climbs a ladder.
-
5
Compare cost per year, not cost today
Asphalt at $12,000 over 25 years is $480/yr. Metal at $24,000 over 60 years is $400/yr. The expensive roof can be the cheaper one — if you stay.
-
6
Check for assistance programs
Some states, municipalities and nonprofits run grants or zero-interest loans for essential home repairs, particularly for older and lower-income homeowners. Worth an hour of searching before you borrow.
Contractor red flags
Most roofers are honest tradespeople doing hard, dangerous work. But roofing attracts storm-chasers precisely because homeowners are frightened, uninformed and in a hurry. These are the patterns that show up in complaint data again and again.
Pros
- +Provides a written, itemised quote with the square count
- +Carries liability insurance and workers' comp — and lets you verify both
- +Pulls the permit themselves and says so in writing
- +Offers a workmanship warranty separate from the material warranty
- +Has a physical local address you can actually find
- +Is content for you to take time and get other bids
Cons
- −Knocked on your door after a storm
- −Demands a large deposit — over a third — before materials arrive
- −Pressures you to sign today, or says the price expires tonight
- −Quotes a single bottom-line number with no breakdown
- −Offers to "cover your deductible" — that is insurance fraud, and you would be a party to it
- −Cannot produce a license or certificate of insurance on request
On deposits
A 10–33% deposit is normal and reasonable — the contractor has to buy your materials. Anything approaching half the job before a single bundle arrives on site shifts all the risk onto you, and it is the single most common pattern in roofing fraud complaints. Pay by card or check, never cash.
Frequently asked questions
A typical asphalt roof replacement runs $8,000 to $16,000, or $350–$750 per roofing square installed. Metal costs $900–$1,600 per square and slate $1,500–$3,000. Your state's labor rate moves the total more than any other single factor.
A 2,000 sq ft home usually has 2,200–2,600 sq ft of roof — roughly 22–26 squares — costing about $9,000–$18,000 for architectural asphalt. Pitch changes this more than anything else, since a steep roof holds substantially more surface.
A roofing square is 100 square feet of roof surface. It is the unit every contractor quotes in, and three bundles of asphalt shingles cover one square. An average American roof is 17–22 squares.
Labor is typically 40–60% of the total, at roughly $150–$300 per square. It tracks local wages, which is why the same roof can cost thousands more in Massachusetts than in Mississippi.
In most U.S. municipalities, yes — a full replacement needs a permit costing $250–$700. Your contractor normally pulls it. Get written confirmation that they will, because unpermitted work can void insurance and resurface at resale.
An overlay saves $1,000–$2,000 in tear-off, but it hides any rot underneath, adds weight, shortens the new roof's life and can void the manufacturer warranty. Most codes also cap you at two layers. It is rarely worth it.
Two to five days of on-site work for a typical 20–25 square roof. The full process — collecting quotes, permit approval, scheduling — usually takes four to eight weeks.
A new asphalt roof recoups around 61% of its cost at resale, the highest of any roofing material. The larger value is defensive: a failing roof kills sales and invites aggressive price negotiation.
Late winter and early spring, when crews have gaps in the calendar. Demand and prices peak in late summer and immediately after major storms.
Materials cost roughly the same for every contractor in your area — they buy from the same suppliers. Large differences almost always come down to labor, overhead, or scope. Compare the square count and the price per square, not the bottom line.
In most states sales tax applies to materials but not to labor on a real-property improvement, though the rules vary and some states tax the whole contract. Our calculator applies your rate to materials only, and lets you adjust it.
Curling or cupping shingles, granules collecting in your gutters, daylight visible through the attic roof boards, sagging, or an age past two-thirds of the material's expected life. Any of these warrants an inspection — ideally an independent, paid one.
