Replacing a roof on a 1,500 square foot house costs roughly $6,300 to $23,700 in 2026, with most homeowners choosing asphalt shingles paying about $7,000 to $9,600 for a full tear-off and replacement. The national average across all materials lands near $9,313, according to This Old House’s 2026 roofing survey. Your final number depends far more on material and roof shape than on the 1,500 figure itself, because the roof is not 1,500 square feet.
That last point trips up most estimates. A house with 1,500 square feet of living space almost never has 1,500 square feet of roof. Get the roof area right first, then apply a material price. The sections below do both.
How much does a 1,500 sq ft house roof cost by material?
For a 1,500 square foot house, expect roughly $6,300 for basic asphalt on the low end and above $23,000 for slate or clay tile on the high end. The table below shows installed cost by material, based on a typical roof area of about 1,800 square feet (18 squares) for a single-story home of this size. Prices include tear-off, underlayment, and labor.
| Material | Installed cost (~1,500 sq ft house) | Per sq ft of roof | Typical lifespan |
|---|---|---|---|
| 3-tab asphalt shingles | $4,400 – $5,400 | $2.45 – $3.00 | 15 – 20 years |
| Architectural asphalt shingles | $5,700 – $9,600 | $3.15 – $5.00 | 25 – 30 years |
| Impact-resistant shingles | $6,750 – $7,740 | $3.75 – $4.30 | 25 – 30 years |
| Standing seam metal | $12,600 – $21,600 | $7.00 – $12.00 | 40 – 70 years |
| Wood shake | $14,000 – $18,000 | $8.00 – $10.00 | 25 – 30 years |
| Clay or concrete tile | $18,000 – $24,000 | $10.00 – $13.00 | 50+ years |
| Slate | $21,000 – $24,000 | $12.00 – $14.00 | 75 – 100+ years |
Per-square-foot ranges for shingles and metal come from SquareDash’s 2026 pricing data; the material totals track This Old House’s 2026 averages, which put asphalt near $7,158, metal near $14,050, wood near $17,455, clay near $23,588, and slate near $23,706 for a house of this size. Ranges are wide because “1,500 sq ft house” covers many roof shapes. For a deeper material comparison, see our roof lifespan by material report.
Why your roof is bigger than 1,500 square feet
A 1,500 square foot house usually has a roof measuring 1,600 to 2,000 square feet, so pricing off the living-area figure understates the job by 100 to 500 square feet. Two things inflate roof area: the slope, which stretches the surface beyond the flat footprint, and the eave overhangs, which typically extend 12 to 24 inches past the exterior walls. Dormers and valleys add more.
Roofers convert footprint to roof area with a pitch multiplier. A steeper roof has more surface for the same footprint. The table shows how the multiplier changes the roof area, and therefore the number of squares you pay for, on a 1,500 square foot single-story footprint.
| Roof pitch | Pitch multiplier | Approx. roof area | Roofing squares |
|---|---|---|---|
| Low (3/12) | 1.03 | ~1,600 sq ft | 16 |
| Moderate (6/12) | 1.12 | ~1,750 sq ft | 17.5 |
| Steep (9/12) | 1.25 | ~1,900 sq ft | 19 |
| Very steep (12/12) | 1.42 | ~2,100 sq ft | 21 |
Roofing Brief calculation: footprint of ~1,500 sq ft including a typical overhang, multiplied by standard pitch factors. One roofing square equals 100 square feet. Because a steep roof can add five or more squares over a low-slope roof, the same house can differ by $1,500 or more in asphalt cost from pitch alone. Homes with a smaller footprint follow the same math; see how the numbers shift on a 1,000 sq ft roof.
Single-story vs two-story: the roof footprint difference
A two-story 1,500 square foot house is cheaper to roof than a single-story one because the same living area sits under a smaller roof. This Old House’s 2026 data shows a single-story 1,500 sq ft home averages about $10,882 over roughly 1,874 roof square feet, while a two-story home of the same living area averages about $5,650 over roughly 973 roof square feet.
The reason is simple: stacking the living space cuts the roof footprint roughly in half. If you are comparing quotes, confirm whether the contractor priced the roof by measured area or estimated from the listing’s square footage, because the two can diverge by thousands of dollars.
What is included in the price
A full roof replacement price bundles labor, materials, tear-off, and disposal into one number, and labor usually leads the cost. In This Old House’s 2026 survey, respondents named labor (65%) and materials (64%) as the top cost drivers, well ahead of hidden damage (about 24%) and permits (about 14%). A standard 1,500 sq ft house replacement generally covers:
- Tear-off and disposal of the existing roof, typically one to two layers.
- Underlayment, drip edge, and ice-and-water shield in valleys and eaves.
- Shingles or panels, plus starter strip and ridge cap.
- Flashing around chimneys, vents, and skylights.
- Ridge vents or other ventilation.
- Permits, cleanup, and magnetic nail sweep.
Items that can raise the number beyond the base quote include replacing rotted decking, adding a second layer of ice-and-water membrane in cold climates, or steep-slope and multi-story labor surcharges. Ask for these as line items so you can compare bids fairly.
What drives the cost up or down
Beyond material and roof size, four factors move a 1,500 sq ft house roof price the most: pitch, complexity, region, and access. Each can shift a quote by several thousand dollars, so a single “average” rarely matches your house.
- Pitch and complexity. Steep roofs and cut-up designs with many hips, valleys, and dormers take longer and waste more material, often 15 to 20 squares ordered to cover 16 to 18 installed.
- Region and labor rates. This Old House’s 2026 regional averages run from about $9,167 in the West to $9,621 in the Northeast, a modest spread nationally but wider in high-cost metros.
- Tear-off layers. Removing two existing layers instead of one adds disposal time and dump fees.
- Material tier. Moving from a builder-grade to a designer shingle line can add roughly $1,900 to $3,800 on a house this size.
Homeowners weighing a premium upgrade often compare shingle tiers directly; our guide on architectural vs luxury shingles breaks down where the extra money goes.
Is a metal roof worth it on a 1,500 sq ft house?
A standing seam metal roof on a 1,500 sq ft house runs about $12,600 to $21,600, roughly double to triple an architectural asphalt roof, but it lasts 40 to 70 years versus 25 to 30 for shingles. Over a 50-year horizon, a homeowner may replace asphalt twice while metal is installed once, which can narrow or reverse the cost gap depending on how long you stay.
Whether the premium pays off depends on climate, resale plans, and local labor rates. In hail-prone or wildfire regions, the durability and Class A fire rating can also affect insurance.

How to estimate your own 1,500 sq ft roof cost
You can ballpark your roof cost in three steps before any contractor visits, using your footprint, your pitch, and a per-square-foot rate. This gives you a number to check bids against, not a final quote.
- Find your roof area. Take the footprint (close to your living area for a single story), add for overhangs, and multiply by the pitch factor from the table above. A 1,500 sq ft single-story home at 6/12 lands near 1,750 sq ft.
- Pick a per-sq-ft rate. Use $2.45 to $5.00 for asphalt or $7.00 to $12.00 for standing seam metal from the material table.
- Multiply and add 10%. Roof area times rate, then add roughly 10% for waste, flashing, and permits.
Example: 1,750 sq ft times $3.50 (mid architectural) equals about $6,125, plus 10% equals roughly $6,700. Always get at least three written quotes, because measured area and local pricing will refine this estimate.
Frequently asked questions
How much does it cost to replace a roof on a 1,500 square foot house? In 2026, expect about $6,300 to $9,600 for asphalt shingles and up to $23,700 for slate or clay tile, with a national average near $9,313. Most homeowners choosing architectural asphalt pay in the $5,700 to $9,600 range once tear-off, underlayment, flashing, and labor are included.
How many squares of shingles do I need for a 1,500 sq ft house? A single-story 1,500 sq ft house usually needs about 16 to 21 roofing squares, since the roof measures 1,600 to 2,100 sq ft after pitch and overhangs. One square covers 100 sq ft. Contractors typically order 15 to 20% extra for waste, hips, valleys, and starter and ridge courses.
Is the roof bigger than the house’s square footage? Yes. A 1,500 sq ft house almost always has a larger roof, typically 1,600 to 2,000 sq ft, because slope stretches the surface beyond the flat footprint and eaves overhang the walls by 12 to 24 inches. Pricing off living-area square footage understates the job, so measure the roof area instead.
How much is a metal roof on a 1,500 sq ft house? A standing seam metal roof on a 1,500 sq ft house costs roughly $12,600 to $21,600 installed, or about $7 to $12 per square foot of roof. That is two to three times an architectural asphalt roof, but metal lasts 40 to 70 years, which can lower lifetime cost for owners who stay long term.
Does a two-story 1,500 sq ft house cost less to roof than a single-story? Usually yes. A two-story 1,500 sq ft home averages about $5,650 versus about $10,882 for a single-story one, because stacking the living space roughly halves the roof footprint. The tradeoff is higher labor rates for working at greater height, though the smaller area still wins on total cost.
How long does it take to replace a 1,500 sq ft roof? Most asphalt shingle replacements on a house this size finish in one to three days, depending on crew size, pitch, and weather. Tear-off of a single layer, dry-in, and reroofing often complete in a day or two, while steep or complex roofs and tile or slate installs can take longer.
