What a full replacement costs in 2026
Most American homeowners replacing an asphalt shingle roof in 2026 pay between $9,500 and $21,000. The national midpoint sits around $13,500 for a typical 2,000-square-foot single-story home with a walkable pitch. That number stretches fast in either direction. A small ranch in a low-cost metro might come in under $8,000. A steep two-story colonial in Boston with premium architectural shingles, full tear-off, and a few sheets of rotted decking can clear $25,000 before anyone mentions metal or tile.
Here is the rough national picture by home footprint, assuming architectural asphalt shingles with tear-off of one layer:
- 1,200 sq ft home (roof area ~1,400–1,600 sq ft): $7,000–$12,500
- 1,800 sq ft home (roof area ~2,100–2,400 sq ft): $9,500–$17,000
- 2,500 sq ft home (roof area ~2,900–3,300 sq ft): $13,000–$24,000
- 3,500 sq ft home (roof area ~4,000–4,600 sq ft): $18,000–$34,000
Notice the roof area runs larger than the home's footprint. Pitch adds surface area, and overhangs add more. A 2,000-square-foot house rarely has a 2,000-square-foot roof. That gap is the first place homeowner estimates go wrong.
Roofing squares: the unit every bid is built on
Roofers price in squares, where one square equals 100 square feet of roof surface. A 2,400-square-foot roof is a 24-square job. Once you think in squares, every bid becomes easy to decompose. In 2026, installed architectural asphalt runs roughly $450–$700 per square in most markets, including tear-off, underlayment, and standard flashing work.
To estimate your own roof area, take the home's footprint (not total living space; ignore the second floor) and multiply by a pitch factor: about 1.05 for a nearly flat roof, 1.12 for a gentle 4/12 pitch, 1.2 for a common 6/12, 1.3 for an 8/12, and 1.42 or higher for steep 10/12-plus rooflines. Add roughly 10% for waste, since shingles get cut at every valley, hip, and edge. A 1,900-square-foot footprint at 6/12 pitch works out to about 2,280 square feet of surface, plus waste, call it 25 squares. At $550 per square, that's a $13,750 job. If a bid lands wildly outside that math, ask why. Sometimes there's a good reason. Sometimes there isn't.
Asphalt, metal, tile, slate: the material decision
Asphalt shingles cover roughly three out of four American homes, and for good reason: they're the cheapest to buy, the cheapest to install, and every roofer in the country knows how to work with them. Three-tab shingles ($350–$500 per square installed) last 18–22 years and are increasingly a builder-grade product. Architectural (dimensional) shingles ($450–$700 per square) last 25–30 years, handle wind better, and look noticeably thicker. Premium "designer" asphalt that mimics slate or shake runs $700–$1,000 per square. If you plan to sell within ten years, architectural asphalt is almost always the right financial answer.
Standing-seam metal costs $900–$1,600 per square installed, roughly double asphalt, and lasts 40–70 years. The panels lock together with raised seams, so there are no exposed fasteners to back out and leak over time. Metal sheds snow, survives hail better than shingles (though it dents), and can drop cooling bills 10–20% in hot climates with a reflective finish. Exposed-fastener metal panels (often sold as "ag panel" or corrugated) cost less, $550–$900 per square, but the rubber washers on those screws are a 15-to-20-year maintenance item.
Clay and concrete tile runs $1,200–$2,200 per square installed and lasts 50–100 years. The catch is weight: tile loads a roof at 600–1,100 pounds per square versus about 250 for asphalt, so homes not originally framed for tile may need structural reinforcement, which adds $1,000–$10,000 depending on the span. Tile dominates in Florida, Arizona, and Southern California, where the climate suits it and crews who can install it correctly are plentiful. In the Midwest, finding a qualified tile crew can be the bigger problem.
Natural slate is the hundred-year roof, often the two-hundred-year roof, at $3,000–$5,000+ per square installed. Copper is in the same territory. These are heirloom materials for homes that justify them. Most buyers in this tier are restoring historic properties, not running a payback calculation.
One way to think about it: divide installed cost by expected lifespan. Architectural asphalt at $550 per square over 27 years costs about $20 per square per year. Standing-seam metal at $1,200 over 55 years costs about $22. The lifetime economics are closer than the sticker prices suggest, which is why the real decision usually comes down to how long you'll own the house and what your market expects.
Pitch, stories, and complexity move labor 20–40%
Crews price the same square differently depending on how hard it is to stand on. A walkable roof, anything from 4/12 up to about 7/12, gets baseline pricing. Push past 8/12 and workers need ropes, anchors, and sometimes scaffolding; production slows and labor climbs 15–25%. At 10/12 and steeper, expect a 30–40% labor premium, and some crews simply pass.
Height matters too. Second-story roofs add 10–15% because every bundle of shingles and every sheet of plywood travels farther, and debris management gets slower. Then there's cut-up complexity: dormers, valleys, hips, multiple ridge lines, skylights, and chimneys all require hand-cutting and extra flashing. A simple gable roof and a heavily articulated roofline of identical square footage can differ by $2,000–$5,000 on the same house size. When two bids on your home disagree sharply on labor, complexity assumptions are usually the reason.
Tear-off versus roof-over
A roof-over, nailing new shingles directly over the old layer, saves $1,000–$2,500 in labor and disposal. Code in most jurisdictions allows a maximum of two layers, so it's only an option if you currently have one. It's also usually a mistake. The new shingles telegraph every bump in the old layer, trap more heat (which shortens their life), and most importantly, nobody ever inspects the decking underneath. Manufacturers may also limit or void wind warranties on roof-overs.
Tear-off costs more upfront but lets the crew examine the deck, replace rotted sheets, install modern synthetic underlayment and ice-and-water shield, and reset all the flashing. When the next replacement comes, you won't pay for a double tear-off, which costs more than the roof-over ever saved. Unless the budget genuinely cannot stretch, tear off.
Decking: the mid-job surprise
Somewhere between 10% and 30% of tear-offs reveal decking damage that wasn't visible from below: rot around chimneys and valleys, delaminated OSB, sagging spans, old plank decking with gaps too wide for modern shingles. Replacement plywood or OSB runs $70–$120 per 4x8 sheet installed in 2026, and a bad roof can need ten or twenty sheets.
You can't fully predict this, but you can control how it's handled. Before signing, get three things in writing: the per-sheet replacement price, who walks the roof and approves the change order (you, by phone, with photos), and whether the contractor's bid already includes an allowance for a set number of sheets. Contractors who refuse to commit to a per-sheet price before the job starts are giving you a preview of how the rest of the project will go.
The line items a good bid spells out
A complete re-roof is more than shingles. These components should appear on the bid by name, with quantity or coverage stated:
- Underlayment — the water barrier between shingles and deck. Synthetic underlayment has largely replaced felt and adds $50–$100 per square job-wide. Cheap bids sometimes still spec 15-lb felt.
- Ice and water shield — self-adhering membrane at eaves, valleys, and penetrations. Required by code in cold climates for the first 3–6 feet up from the eave. Roughly $60–$100 per roll covering about 2 squares.
- Drip edge — metal flashing along eaves and rakes that keeps water off the fascia. Code-required almost everywhere now, about $2–$4 per linear foot. Its absence on a bid is a red flag.
- Flashing — step flashing at sidewalls, counterflashing at chimneys, boots at pipes. Reusing old flashing saves the contractor money and costs you leaks three years later. New chimney flashing alone runs $300–$600.
- Ridge vent — continuous exhaust ventilation at the peak, $7–$12 per linear foot installed. Proper attic ventilation is also a condition of most shingle warranties, so this line item protects the rest of the purchase.
- Disposal — dumpster, hauling, and landfill fees, typically $400–$900 depending on layers and local tipping rates.
Where the money goes: labor versus material
On a standard asphalt job, expect roughly 60% labor and overhead, 40% materials. This split is why regional wages move roofing prices more than commodity prices do, and why the same shingle costs so much more to install in San Jose than in San Antonio. It also explains the premium-material math: on a metal or slate roof the materials share rises, but skilled-trade labor for those systems costs more per hour too, so the split never tilts as far toward materials as homeowners expect.
Asphalt shingle prices themselves have climbed steadily since 2021, since they're an oil-derived product and manufacturers have pushed through repeated increases. Several major brands now announce price bumps once or twice a year. If you receive a bid in late winter, ask how long it's valid; 30 days is common precisely because of material repricing.
Regional variation is real money
The same 25-square architectural asphalt job might run $10,500 in Oklahoma City, $14,000 in Chicago, and $19,000 in coastal California. Drivers include prevailing wages, permit and inspection regimes, wind-zone code requirements (Florida's fastening and underlayment rules add cost on purpose), snow-load framing standards, and plain old demand. Hail states like Texas, Colorado, and Oklahoma run hot-and-cold pricing: after a major storm, demand spikes, out-of-town crews flood in, and both prices and quality get volatile. If you can wait three or four months after a regional hail event, bids usually settle.
Insurance claims: RCV versus ACV
When wind, hail, or a fallen tree damages the roof, homeowner's insurance often pays for most of the replacement, but the policy type controls how much. A replacement cost value (RCV) policy pays the full cost of a new equivalent roof minus your deductible, usually in two checks: an initial payment at actual cash value, then a "recoverable depreciation" check after you prove the work was completed. An actual cash value (ACV) policy pays only the depreciated worth of the old roof. A 15-year-old shingle roof with a 25-year expected life might be 60% depreciated, leaving you with 40% of replacement cost minus deductible. Some insurers have quietly moved older roofs onto ACV schedules at renewal; read your declarations page before you need it.
Practical sequence: photograph the damage immediately, including date-stamped close-ups and wide shots. Get a reputable local roofer's inspection report before or alongside the adjuster's visit. File promptly, since most policies set a claim window of one year or less from the date of loss. And be wary of storm-chasing canvassers offering to "waive your deductible"; deductible waiving is insurance fraud in most states and a felony in several.
How to read a roofing bid, and the upsells to question
A trustworthy bid itemizes: tear-off (with number of layers), decking allowance and per-sheet rate, underlayment type by brand, ice and water shield coverage, drip edge, flashing scope (new versus reused, stated explicitly), shingle brand and line, ridge vent, disposal, permit, and both warranties. One-line bids that say "install new roof: $14,800" tell you nothing and leave every dispute in the contractor's favor.
Common upsells worth scrutiny: upgraded "Class 4" impact-resistant shingles are genuinely worth it in hail states (many insurers discount premiums 5–20% for them) and rarely worth it elsewhere. Full gutter replacement bundled into a roof job is sometimes sensible, sometimes padding; gutters in good shape can be protected and reused. "Complete attic ventilation overhauls" deserve a second opinion, though genuine ventilation defects do need fixing. Skylight replacement during a re-roof, on the other hand, is an upsell you should usually accept: a 15-year-old skylight reinstalled into a new roof is the most likely future leak point, and replacing it later costs far more than the $300–$800 incremental cost now.
Two warranties, and only one of them covers the likely failure
Every roof comes with a material warranty from the manufacturer, commonly marketed as "limited lifetime" for architectural shingles. Read the fine print: full coverage typically lasts only the first 10–15 years, then prorates steeply, and it covers defective shingles, not defective installation. Manufacturing defects are rare. Installation errors are not.
That's why the workmanship warranty from your contractor matters more. Typical coverage runs 2–10 years; better contractors offer 10–25. It's only as good as the company behind it, so a 25-year promise from a two-year-old business means little. Some manufacturers offer enhanced system warranties (covering workmanship for 25–50 years) when a certified contractor installs the full branded system; these add $500–$1,500 and can be worthwhile if you intend to stay in the home, partly because they survive even if the installer goes out of business.
Permits and timing
Re-roof permits run $250–$1,500 depending on the city, and some jurisdictions require engineering documentation for wind or snow loads. The permit should be pulled by the contractor under their license, never by you as an "owner-builder" to save them a step, since the permit holder carries responsibility for code compliance.
Seasonally, late spring through early fall is peak roofing season, with the best crews booked 4–8 weeks out. Late fall pricing often softens 5–10% as contractors fill their remaining calendar. Winter installs are possible in much of the country and sometimes discounted further, but asphalt shingles need a stretch of weather above roughly 40°F to thermally seal, so a January install in Minnesota carries real risk of wind damage before sealing occurs. In the South, winter is arguably the best time to buy.
Always verify with a local contractor
