How Much Does It Cost to Replace a Roof on a 1500 Square Foot House

Short answer

• There is no single price for replacing a roof on a 1,500 square foot house, and any guide that gives you one number without explaining material, roof size, pitch, location, and labor is leaving out the parts that decide your bill. The honest answer is a range, with clear reasons why your quote may sit at the low end, in the middle, or well above it. For planning, This Old House puts a complete replacement for a typical 1,500 square foot house at about $9,313 on average, within a range of $7,158 to $23,706, depending on floors, location, and material. Angi data, reported by NerdWallet in a guide updated September 16, 2025, points the same way: about $9,500 on average across house sizes, at roughly $4 to $11 per square foot of roof for typical materials. HomeGuide, accessed November 3, 2026, reports a national average of $10,800 for an asphalt shingle roof and an average range of $5,700 to $16,000. Every figure here is a US national range estimate from a named published source, with the source date stated. None of them is a quote for your house. Prices vary by material, measured roof area, pitch, complexity, tear off, region, permits, and deck condition, and only a local contractor who has measured your roof can price your job. Use the ranges to compare materials, to understand what a quote should include, and to spot a quote that looks unusually low or high for the work described. This article is general information only. It is not a quote, a bid, or advice about your specific roof.

Why a 1,500 Square Foot House Does Not Have a 1,500 Square Foot Roof

The first misunderstanding to clear up is measurement. The 1,500 square feet in the question usually refers to living space, not roof surface area. A roof is pitched, so its surface is larger than the footprint it covers, and it usually extends past the walls at the eaves. Roofers measure and price in squares, where one square equals 100 square feet of roof surface.

This Old House explains the effect with two houses that have the same living area. Using a standard 6/12 pitch, meaning the roof rises 6 inches for every 12 inches of horizontal run, and one foot eave overhangs, a single story 1,500 square foot house needs roughly 1,874 square feet of roofing material, or about 19 squares. A two story house with the same 1,500 square feet of living space stacks that space over a smaller footprint, so it needs only about 973 square feet of roofing material, or about 10 squares. That difference alone moves the total by thousands of dollars before material or labor quality is even considered. If you are comparing house forms while you plan, our guide to different types of houses explains how footprint and stories change the shell of the home, and the roof follows the footprint.

Pitch changes the math further. Roof area is the footprint multiplied by a pitch factor:

• 4/12 pitch: multiply the footprint by about 1.05.
• 6/12 pitch: multiply by about 1.12.
• 8/12 pitch: multiply by about 1.20.
• 10/12 pitch: multiply by about 1.30.
• 12/12 pitch: multiply by about 1.41.

So a 1,500 square foot footprint at a gentle 4/12 pitch has roughly 1,580 square feet of sloped surface before overhangs, while the same footprint at a steep 12/12 pitch has roughly 2,120 square feet. Add eaves, waste, and extra material for valleys, hips, and dormers, and roughly 17 to 22 squares, or 1,700 to 2,200 square feet, is a common planning range for a single story house of this size. Two houses with the same floor area can therefore receive very different quotes because they do not have the same roof. Always ask a contractor to state the measured roof area in squares on the quote itself, so you can compare quotes on the same basis.

What the Published Estimates Say for This House Size

Published sources differ, and the difference is itself useful information, because each source counts a slightly different job.

This Old House, in its guide to replacing a roof on a 1,500 square foot house accessed November 3, 2026, reports an average of about $9,313 and a range of $7,158 to $23,706. Its method matters: it works out roof area from home size, stories, and a 6/12 pitch with one foot eaves, converts that area to squares, and prices the squares using RSMeans data from Gordian, a construction pricing database used by contractors. By stories, it reports a single story house at about $10,882 on average, within $8,364 to $27,701, and a two story house at about $5,650 on average, within $4,343 to $14,383, because the two story roof is so much smaller.

Angi data tells a consistent story. NerdWallet, updated September 16, 2025 and citing Angi, reports an average of about $9,500, a typical total range of about $5,800 to $46,000 across all sizes and materials, and a typical installed rate of about $4 to $11 per square foot. HomeGuide reports a national average of $10,800 and an average range of $5,700 to $16,000, and breaks a typical square into about $100 to $300 for removal, $100 to $250 for materials, and $200 to $350 for labor, or $400 to $900 per square in total.

One further benchmark explains why some quotes look much higher. The Remodeling Cost vs Value report for 2025, published by the Journal of Light Construction and Zonda, prices one fully specified job: tear off to bare sheathing, then 30 squares, or 3,000 square feet, of fiberglass asphalt shingles with new underlayment, drip edge, flashing, and work at two skylights. That job averaged $31,871 nationally, or about $1,062 per square, and added an estimated $21,501 in resale value, or about 67.5 percent of its cost. The same report priced a 30 square standing seam metal roof at $51,865, recouping about 50.1 percent. That benchmark roof is far larger than most 1,500 square foot houses need, so do not apply its total to your house. Use it instead to see why a quote with full tear off, new flashing everywhere, and skylight work costs more per square than a simple reshingle quote.

Treat all of these as planning ranges, not as quotes. Your actual price will be set by a local contractor who has measured your roof, checked its condition, and priced your material and labor market.

Cost by Material, Worked for a 1,500 Square Foot House

Material choice usually moves the price more than any other single factor. The clearest way to see it is to apply published installed rates to one fixed roof size. The worked examples below use the single story roof area from This Old House, about 1,874 square feet, and the installed per square foot ranges published by HomeGuide, accessed November 3, 2026. They are arithmetic examples to compare materials on the same roof, not quotes, and they assume a straightforward roof of average complexity.

• Three tab asphalt shingles: $3 to $5 per square foot installed in HomeGuide, which works out to about $5,622 to $9,370 on a 1,874 square foot roof. HomeGuide gives a typical lifespan of 15 to 20 years for three tab shingles. This is usually the lowest upfront cost option, with the shortest service life.
• Architectural or dimensional asphalt shingles: $4 to $6 per square foot installed, or about $7,496 to $11,244 on the same roof, with a HomeGuide lifespan of 20 to 30 years. The thicker, layered profile is the most common upgrade from three tab and is the basis for the This Old House figure of $7,158 for asphalt on a 1,500 square foot home, which blends one and two story houses.
• Metal roofing: $5 to $16 per square foot installed across metal types, or about $9,370 to $29,984 on the same roof. Standing seam metal sits at $9 to $16 per square foot in HomeGuide, or about $16,866 to $29,984 here, while simpler metal panels sit lower. HomeGuide gives metal a lifespan of 30 to more than 80 years depending on type. This Old House puts metal for this house size at $14,050, inside that worked range. If you choose metal, basic care still matters over decades, and our guide to how to get rust off metal covers the surface corrosion side of metal care around the home.
• Wood shakes and shingles: $7 to $15 per square foot installed, or about $13,118 to $28,110 on the same roof, with a HomeGuide lifespan of 25 to 30 years. This Old House puts wood at $17,455 for this house size. Wood needs more maintenance than asphalt or metal, and some fire prone areas restrict it under local codes, so check your code first.
• Clay and concrete tile: $7 to $25 per square foot installed, or about $13,118 to $46,850 on the same roof, with a HomeGuide lifespan of 30 to more than 100 years. This Old House puts clay at $23,588 for this house size. Tile is heavy, so a house framed for asphalt may need structural assessment, and sometimes reinforcement, before tile is approved, at extra cost.
• Slate: $10 to $30 per square foot installed, or about $18,740 to $56,220 on the same roof, with a HomeGuide lifespan of 50 to more than 200 years for natural slate. This Old House puts slate at $23,706 for this house size, near the low end of the worked range. Slate needs specialist installers and, like tile, may need structural work because of its weight.
• Flat and low slope systems, such as TPO, EPDM rubber, and modified bitumen: $3 to $11 per square foot installed in HomeGuide for flat roofs overall. These systems belong on low slope sections, such as a porch or addition roof, rather than on a main pitched roof.

Use these figures to compare materials in relative terms: asphalt is generally the lowest upfront cost, metal sits in the middle to high range with long life, and tile and slate sit at the premium end. Because a roof is also the most visible part of the house from the street, material color and profile are worth weighing alongside price, as our overview of the outside design of a house explains. Do not use any figure here as a budget without local quotes.

Labor, Tear Off, and the Line Items People Forget

A roof replacement is not just shingles. NerdWallet, citing Angi, notes that labor accounts for more than half of a typical total, with the remainder covering materials, and that roofers generally charge around $40 to $90 per hour per worker. HomeGuide puts installation labor for shingles and flat roofs at about $1.50 to $3.00 per square foot, rising to $4 to $17 per square foot for premium materials such as tile and slate. In the 2026 This Old House Roofing Survey of 1,000 recent roof buyers, labor and materials were the factors most often cited as top contributors to the final price.

Labor covers more than laying the new surface. A full replacement normally includes tear off and disposal, deck inspection, new underlayment and, where climate requires it, ice and water shield at eaves and valleys, flashing around chimneys, vents, and skylights, ridge caps, and ventilation. HomeGuide prices tear off at $1 to $5 per square foot: about $1 to $3 for shingles or metal, and $2 to $5 or more for heavy slate or tile. Two layers take longer to remove than one, so ask how many layers your roof has and how the quote prices them.

The costs that surprise people are usually the smaller lines:

• Permits: HomeGuide lists permits at $100 to $500 depending on location. NerdWallet likewise advises anticipating up to $500 where a permit is required.
• Decking repair: HomeGuide prices decking replacement at $2 to $5 per square foot installed. Rotten decking is often only visible after tear off, so no honest quote can fix this line in advance. Agree the rate before work starts.
• Underlayment: HomeGuide lists underlayment materials at about $0.10 to $0.80 per square foot, typically included in an estimate. Confirm whether felt or synthetic is specified, and where ice and water shield will be fitted.
• Ventilation: HomeGuide lists roof vent installation at $200 to $700. A replacement is the cheapest moment to correct poor attic ventilation, which affects shingle life and attic moisture.
• Flashing and gutters: flashing is usually included in an estimate, but confirm it in writing. Gutter replacement, if you add it, is listed by HomeGuide at $12 to $25 per linear foot, normally as a separate line.
• Inspection: a standalone roof inspection is listed by HomeGuide at $100 to $400, worthwhile before you commit to replacement rather than repair.

Ask for each item to be listed separately in a quote, so you can see what is included and what is an allowance that may change once the old roof is off. A low total that excludes tear off, flashing, or ventilation is not cheaper than a higher total that includes them. It is a different job.

How Pitch, Complexity, and Condition Move the Price

Complexity adds cost in predictable ways, on top of the area effect explained earlier. Steep pitches need more safety equipment and slower work. NerdWallet, citing Angi, notes that a steeply sloped roof can add an additional $1,000 to $3,000 to a replacement, and HomeGuide notes that pitches over 6/12 require extra safety precautions and more labor. Height does similar work: a two story house has a smaller roof, but working at greater height can command higher labor rates, which is one reason the two story saving in the This Old House figures is smaller than the area difference alone would suggest.

Each break in the roof surface adds flashing and hand work. Valleys, dormers, skylights, chimneys, and vent pipes each need careful detailing, and each is a common leak point if rushed. A simple gable roof is the cheapest shape to replace per square foot. A cut up hip roof with several valleys, two chimneys, and skylights prices higher per square foot in the same material and town.

Condition is the third mover. Multiple layers, rotted decking, damaged trusses, and long term leaks all add work that a surface only estimate misses. This Old House notes that deck repairs are a common unexpected cost once the old roof is removed, and that truss or rafter repairs may also be needed, especially after long term leakage. Build a contingency into your budget and get the deck repair rate agreed in writing before tear off day.

How Region Changes the Same Roof

Location moves the price through labor rates, material availability, climate demands, and building codes. This Old House reports these average totals for a 1,500 square foot house by region: Northeast $9,621, Midwest $9,598, South $9,427, and West $9,167. That spread looks modest because it averages whole regions. City level differences are larger: the 2025 Cost vs Value report priced the same specified 30 square asphalt job differently from city to city, and high cost metropolitan labor markets sit well above national averages.

Climate also changes the specification, not just the rate. Coastal and hurricane prone regions may require wind resistant materials and reinforced installation. Colder regions may require ice and water shield and detailing that resists ice dams. Wildfire prone areas may restrict wood roofing. Urban areas often show higher labor rates than rural areas in the same state. That is why a national average should never be treated as your price: use national ranges to plan and compare materials, and local quotes to budget.

A replacement is also the natural moment to think about what sits under the roof. Ventilation and underlayment affect how the house holds heat and moisture. Our guide to how to design energy efficient homes explains how the roof and attic fit into whole house energy performance, worth reading before you sign a specification you will live under for decades.

Repair or Full Replacement

Also ask whether repair, rather than full replacement, is sensible. If damage is isolated, such as a small leak at one flashing or a limited area of storm damage on an otherwise sound young roof, a targeted repair may cost far less and be the right job. If the roof is near the end of its expected life, has widespread curling, cracking, or missing shingles, or has deck damage, repeated repairs can become a costly delay that still ends in replacement.

A general planning guide is to consider replacement seriously when a repair would cost roughly a third or more of a new roof, or when remaining life is short. That is a guide for framing the conversation, not a rule for your roof. Age helps too: This Old House notes that an asphalt shingle roof approaching 20 years old is likely nearing the end of its useful life regardless of appearance, while a younger metal or tile roof with local damage is usually a repair candidate instead. A professional inspection is the reliable way to decide.

How to Get a Reliable Local Quote

A reliable quote process looks like this:

1. Ask at least three local, licensed, and insured contractors to measure the roof itself, not only the house footprint.
2. Ask for the roof surface area in squares, the material by brand and line, the underlayment type, and the flashing, ventilation, tear off, disposal, and permit terms, each stated in writing.
3. Ask how deck repair is priced, and whether there is a cap or a per sheet or per square foot rate that applies after tear off.
4. Ask for warranty terms separately for material and workmanship, including who honors each one and for how long.
5. Ask whether the quote includes gutters, skylights, chimney flashing, and ventilation, or whether those are separate lines.
6. Clarify what replacement means in the quote: full tear off to the deck, or a roof over, meaning a new layer over the existing roof. A roof over saves removal cost but adds weight, can shorten the new roof life, and is not permitted everywhere. HomeGuide notes that most cities limit roofs to a maximum of two layers.
7. Compare quotes line by line, not only by total, because a lower total may exclude work that another quote includes.
8. Check references, license status, and insurance, and read the contract, including payment schedule and cleanup terms, before paying a deposit.

Timing can help at the margin. Late spring through early fall generally offers the best installation conditions, since moderate temperatures allow asphalt shingles to seal properly, while peak season demand can raise prices and waiting times. This Old House advises prioritizing proper installation conditions over small savings, because poor weather installation can lead to early failure and warranty problems.

Frequently Asked Questions

How much should a 1,500 sq ft roof cost

For planning, This Old House reports about $9,313 on average for a 1,500 square foot house, within $7,158 to $23,706, and HomeGuide reports a national average of $10,800 with an average range of $5,700 to $16,000 for asphalt. Angi data reported by NerdWallet puts a 1,500 square foot roof area at about $6,000 to $16,500 at typical rates. Your local quote is the only figure that applies to your roof.

How much does it cost to reroof a 1,500 square foot house

Reroofing usually means the same full replacement work described here: tear off, deck check, underlayment, flashing, and new roofing at the prices above. If a contractor uses reroofing to mean laying a second layer over an existing roof, that is a different job, with different code, weight, and warranty implications, and it is not permitted in all areas. Clarify which meaning each quote uses.

Does a 1,500 square foot house need 1,500 square feet of roofing

Usually no. Because of pitch and overhangs, roof surface area is usually larger than living area on a single story house. This Old House works out about 1,874 square feet of roofing for a single story 1,500 square foot house at a 6/12 pitch, and about 973 square feet for a two story house of the same living area. Ask for the measured roof area in squares.

How many squares is a 1,500 square foot house roof

One square is 100 square feet of roof surface. On the This Old House worked basis, a single story 1,500 square foot house needs about 19 squares, and a two story house needs about 10 squares. Steeper pitch, larger overhangs, and a more complex shape raise the count, which is why quotes should state squares explicitly.

How long does a 1,500 square foot roof replacement take

A straightforward tear off and replacement on a house of this size commonly takes about 2 to 4 days of on site work with a full crew. That is a general planning range, not a schedule promise. Weather, steep pitch, complex detailing, premium materials such as tile or slate, and deck repairs found after tear off can all extend it.

Why do quotes for the same house vary so much

Because quotes often describe different jobs. One may include full tear off, new flashing, ventilation, and permits, while another excludes some of those lines or assumes a roof over. Material brand and line, deck repair rates, warranty length, and crew labor rates also differ. Compare line by line on the same measured squares before comparing totals.

Does a new roof add value to the house

It can add resale value, but usually less than it costs. The 2025 Cost vs Value report estimated that its specified asphalt shingle replacement, at $31,871 for a large 30 square roof, added about $21,501 at resale, or about 67.5 percent of cost, while its metal roof added about 50.1 percent. Those percentages describe that report’s specified jobs, not a promise for any individual house or sale.
