Roof Replacement Cost

Enter your roof size and pitch to get a 2026 replacement estimate with the full material and labor breakdown. Every number is itemised, so you can check the math before you talk to a contractor.

Most homeowners pay $10,206 to $15,987 to replace an asphalt shingle roof on a 1,700 sq ft house in 2026, or about $6.00 to $9.40 per square foot of floor area, including tear-off. Roof area, pitch and the number of existing layers drive most of the difference.

Asphalt shingle roof cost

Asphalt covers about four out of five American roofs, so it is the default this calculator prices. What changes the number most is not the shingle you pick, it is how much of the old roof has to come off first.

Scope of work Per square Per sq ft of roof 1,700 sq ft home
New shingles over a bare deck New construction or an addition. No old roof to remove. $348 – $542 $3.48 – $5.42 $6,608 – $10,304
Shingle replacement, deck reused Shingles and underlayment come off, the deck stays. $425 – $671 $4.25 – $6.71 $8,082 – $12,746
Full replacement including tear-off What most people mean by a new roof. Disposal included. $537 – $841 $5.37 – $8.41 $10,206 – $15,987

Watch the unit. The columns above are per square and per square foot of roof surface, which is what a roofer quotes. A 1,700 sq ft house at a 6/12 pitch carries about 1,901 sq ft of roof, or 19.0 squares. Quotes given per square foot of floor area look cheaper for the same job, so check which one you are reading before comparing two bids.

Need the material order rather than the price? The roof shingle calculator converts the same roof into bundles, starter strip and ridge cap.

Ready for real quotes?

The number above is a planning figure built from national material prices and BLS wage data. It cannot see your deck, your access or your local disposal fees. Only a roofer standing on your property can, and three of those quotes is what turns this estimate into a decision.

1. Call

Give your ZIP code, the work you need and rough roof size. The estimate you just ran is enough detail.

2. Get matched

You are put in touch with licensed roofing contractors who work in your area and take that kind of job.

3. Compare

Hold each written quote against the itemised breakdown above. A bid that is far off should be explainable line by line.

How this calculator works

Every roofing estimate is the same two things added together: how much material the roof needs, and how many crew hours it takes to install. This calculator does both explicitly.

1. Footprint becomes true roof area

A sloped roof covers more surface than the ground beneath it. We multiply your footprint by the pitch multiplier, 1.118 at 6/12 and 1.414 at 12/12, to get the area a roofer actually has to cover. That area divided by 100 gives roofing squares, the unit the trade buys and bids in.

Where the 6/12 pitch multiplier comes from A right triangle. The horizontal side is the run, 12 units. The vertical side is the rise, 6 units. The sloping side is the rafter, which is the actual roof surface. By Pythagoras the rafter is the square root of 12 squared plus 6 squared, so every square foot of floor area carries 1.118 square feet of roof. Run: 12 Rise: 6 Rafter 26.6° Ridge Eave
A 6/12 pitch rises 6 inches for every 12 inches of run, which is 26.6 degrees. The rafter is 1.118 times the length of the run, so a 1,700 sq ft footprint at this pitch carries about 1,901 sq ft of roof. That multiplier is why roof area and floor area are never the same number.

2. Squares become a material take-off

Each material carries its own per-square quantities: three bundles of asphalt shingles per square, underlayment rolls, drip edge by the perimeter foot, ridge cap, fasteners and flashing. A waste factor is applied on top: 12% for a straightforward asphalt roof, 18% for slate and cedar where cuts waste more.

One roofing square, and the 3 bundles that cover it A square grid ten cells wide and ten cells tall, each cell one square foot, making 100 square feet in total. That is one roofing square. Beside it are 3 stacked bundles of asphalt shingles, which is what it takes to cover that area. 10 ft 10 ft 1 square 100 sq ft 3 bundles
A roofing square is 100 square feet of roof surface, not one square foot. Roofers order and price in squares, and standard asphalt shingles run 3 bundles to the square. Converting early is what keeps the material order and the labor bid talking about the same roof.

3. Crew hours become labor cost

Labor is hours-per-square multiplied by a billed crew rate. A full tear-off and replacement runs about 3 man-hours per square. The billed rate starts at a $78/hour national figure, which reflects a $27.95 median roofer wage plus roofing's unusually heavy burden, since workers' compensation class 5551 is the most expensive classification in the trades, plus overhead and profit. Choosing a state re-prices that labor against BLS wage data for your area.

4. Permits and disposal

Roof replacement is permitted work almost everywhere. We add the national permit band of $150 to $500 when a permit is normally required, and skip it for repairs that usually are not.

Frequently asked questions

How much does a new roof cost in 2026?

A typical asphalt shingle roof replacement runs about $6.00 to $9.40 per square foot of floor area including tear-off, or roughly $10,206 to $15,987 on a 1,700 square foot home. The three inputs that move the number most are roof area, pitch, and whether the old roof has to come off first.

How much does an asphalt shingle roof cost per square?

Between $348 and $841 installed, depending on how much of the old roof comes off. New shingles over a bare deck run $348 to $542 per square, while a full replacement with tear-off and disposal runs $537 to $841. A square is 100 square feet of roof surface, so a 1,700 square foot house at 6/12 is about 19.0 squares.

Is it cheaper to shingle over an old roof than to tear it off?

Up front, yes. Laying new shingles without a tear-off costs $6,608 to $10,304 on a 1,700 square foot home against $10,206 to $15,987 for a full replacement, because you skip the labor and the disposal. The catch is that most codes cap a roof at two layers, the second layer runs hotter and ages faster, and nobody inspects the deck for rot on the way. It is a way to buy years, not a way to buy a roof.

How is roof replacement cost calculated?

Cost is material quantity plus crew hours. We take your footprint, stretch it by the pitch multiplier to get true roof area, convert to roofing squares, apply per-square material quantities and a waste factor, then add labor hours at a regional crew rate. Permit fees are added where a permit is normally required.

Why is my roof area bigger than my house footprint?

A sloped roof is longer than the ground it covers. A 6/12 pitch multiplies footprint by 1.118, and a 12/12 pitch by 1.414. So a 1,700 square foot footprint at 6/12 is about 1,900 square feet of actual roof, roughly 19 roofing squares.

What is a roofing square?

A roofing square is 100 square feet of roof surface. Roofers price and order in squares, and one square takes three bundles of asphalt shingles. Converting to squares early is how estimates stay consistent between the material order and the labor bid.

Does a steeper roof cost more to replace?

Yes, twice over. A steeper pitch increases the actual surface area you are covering, and it slows the crew down because they need staging and fall protection. Most contractors add a steep-slope charge of $0.50 to $2.00 per square foot above an 8/12 pitch.

Do I need a permit to replace a roof?

In most U.S. jurisdictions, yes. Roof replacement is regulated work because it affects the building envelope and structure. Permit fees average about $224 nationally and commonly land between $150 and $500. Repairs below a certain value are usually exempt.

How accurate is this calculator?

It is a planning figure, not a quote. Material prices come from published 2026 retail pricing and labor from U.S. Bureau of Labor Statistics wage data adjusted for burden and overhead. It cannot see your deck condition, access constraints, or local disposal fees, which is why every result is shown as a range.
