Metal roof cost calculator: check a metal roof quote
Most metal roof calculators skip actual roof area. A 2,000 sq ft footprint at 6:12 pitch is 2,236 sq ft of roof (22.4 squares). Standing seam at $14 per square foot plus $1.50 tear-off: $34,658. Overwrite any rate.

How this is worked out
- The slope multipliers are geometry, not estimates. A pitch of rise:12 turns footprint into roof area by a factor of the square root of 1 plus (rise/12) squared. 6:12 gives 1.118, 12:12 gives 1.414. This is the single biggest reason online roof estimates come in low: they price the floor plan, not the roof.
- The per-square-foot rates are placeholders, and you should replace them. The panel-type figures are midpoints of typical 2026 US installed quotes for a straightforward re-roof. They vary widely by region, gauge, panel profile, roof complexity, height, and installer.
- They come from no official publication, so we label them typical quote figures, not sourced data. Enter your own number in the rate field and the calculator uses it instead.
- Tear-off defaults to one layer of asphalt shingles. Extra layers, cedar shake, tile, steep pitch and county dump fees all move it. Installing over an existing roof avoids the cost but is not always allowed by local code and can trap moisture, so ask your roofer and your building department.
- Waste allowance affects material ordered, not installed cost. Installed per-square-foot pricing normally already includes the roofer's waste; the order figure is there for anyone buying panel and hiring labor separately.
- Not included: structural repair to the deck, new underlayment upgrades, insulation, skylight replacement, gutters, snow guards, permits, or the cost of a roof that needs framing work. Ask for each of these as a named line on the quote.
- There is no federal tax credit for a metal roof in 2026. Roofing is not on the IRS list of qualifying property for the energy efficient home improvement credit. That credit covers only qualifying property placed in service before December 31, 2025 (irs.gov).
- If a quote includes one, ask for the statute. See our credit and insurance guide.

Roof pitch to real roof area, squares and installed cost
Last updated
The table roofing calculators usually skip. For a 2,000 sq ft footprint: the actual roof each pitch produces, the squares, and the panel to order at a 10% waste allowance. Costs use the default $15.50 per square foot installed ($14 standing seam plus $1.50 tear-off).
Roof area = footprint x slope multiplier, where the multiplier is the square root of 1 plus (rise/run) squared. That part is geometry and is exact. Squares = roof area / 100, the unit US roofers quote in. Order area adds a 10% waste allowance. The cost column multiplies roof area by $15.50 per square foot, the calculator's default of $14 standing seam installed plus $1.50 tear-off; those two rates are typical 2026 US quote figures, not sourced from any official publication, and both are user inputs on the calculator so you can substitute your own. Every row here is computed with the same expressions the calculator runs.
| Roof pitch | Slope multiplier | Roof area on a 2,000 sq ft footprint | Squares | Panel to order (10% waste) | Installed cost at $15.50/sq ft |
|---|---|---|---|---|---|
| 3:12 | 1.031 | 2,062 sq ft | 20.6 | 2,268 sq ft | $31,961 |
| 4:12 | 1.054 | 2,108 sq ft | 21.1 | 2,319 sq ft | $32,674 |
| 5:12 | 1.083 | 2,166 sq ft | 21.7 | 2,383 sq ft | $33,573 |
| 6:12 | 1.118 | 2,236 sq ft | 22.4 | 2,460 sq ft | $34,658 |
| 8:12 | 1.202 | 2,404 sq ft | 24.0 | 2,644 sq ft | $37,262 |
| 10:12 | 1.302 | 2,604 sq ft | 26.0 | 2,864 sq ft | $40,362 |
| 12:12 | 1.414 | 2,828 sq ft | 28.3 | 3,111 sq ft | $43,834 |
- Roof pitch changes what you pay for: the same 2,000 sq ft footprint is 2,062 sq ft of roof at 3:12 and 2,828 sq ft at 12:12, a 37% difference in area before anyone talks about price.
- A roofing square is 100 square feet, so a 2,000 sq ft footprint at a 6:12 pitch is 22.4 squares, not 20.
- Roofing is not on the IRS list of property qualifying for the energy efficient home improvement credit, and that credit only applies to qualifying property placed in service before December 31, 2025, so there is no federal metal roof tax credit for a 2026 installation.

Common questions
How much does metal roofing cost?
Our index reads 14 US roofers' own price pages. Installed metal roofing starts at $6 to $12 per square foot (median start $7.50, read 12 October 2026); tops run $12 to $35. This metal roof estimate calculator turns footprint and pitch into roof area and squares, times your rate. Use your quote's rate for a genuine estimate.(Metal Roof Installed Price Index, 14 US roofers' own price pages, read 12 October 2026)
How do I calculate metal roof cost per square foot?
Divide the quoted total by the measured roof area, not by your house size. Roof area is your footprint multiplied by the slope multiplier for your pitch: 1.054 at 4:12, 1.118 at 6:12, 1.414 at 12:12. If the quote is per square, divide by 100 to get per square foot.
How much does a standing seam metal roof cost per square foot?
Four roofers in our price index price standing seam on their own pages. They start at $10 to $12 per square foot installed, with tops at $16 to $35 (read 12 October 2026). The calculator's $14 starting figure sits inside all four ranges, plus tear-off per square foot of roof. Enter your quotes' rate above for your total.(Metal Roof Installed Price Index, 14 US roofers' own price pages, read 12 October 2026)
How do I get a metal roof estimate?
A metal roof estimate starts with the roof, not the house. Footprint times your pitch's slope multiplier gives roof area; divide by 100 for squares. Multiply area by an installed rate and add any tear-off. This metal roof cost estimator runs each step. Ask roofers giving metal roofing estimates for the measured area they priced.
How do I check a metal roof quote?
Divide the quoted total by the roof area the roofer measured, then remove any tear-off. That is the installed rate per square foot to compare. Our 14 US roofers start at $6 to $12: median $7.50, middle half $7.00 to $10.25 (read 12 October 2026). Well above their tops? Ask about gauge, coating, tear-off layers and bundling.(Metal Roof Installed Price Index, 14 US roofers' own price pages, read 12 October 2026)
Is this a standing seam cost calculator too?
Yes. Choose standing seam and the calculator starts at $14 per square foot installed. Our index's four standing seam roofers publish $10 to $35, $10 to $20, $12 to $20 and $12 to $16 per square foot (read 12 October 2026). Type your own standing seam quote's rate over it.(Metal Roof Installed Price Index, 14 US roofers' own price pages, read 12 October 2026)
Does it work as a steel roof calculator for corrugated panels?
Yes. The exposed-fastener corrugated or ribbed steel option starts at $7 per square foot installed. Western States Metal Roofing publishes $7.00 to $13.00 per square foot for corrugated roofing installed. Simmitri publishes about $7 to $12 per square foot all-in for exposed fastener systems (read 12 October 2026).(Metal Roof Installed Price Index, 14 US roofers' own price pages, read 12 October 2026)
Can I use it as a metal roof material cost calculator?
For the quantity, yes. As a metal roof material calculator it gives the panel area to order, waste included, which is what a supplier prices. It carries no material-only price, because there is no published one to cite. Multiply that order area by your supplier's panel price. The installed totals above already include the roofer's material.
Is this a tin roof calculator?
In the sense most people mean, yes: 'tin roof' is the everyday name for a metal roof. The Metal Roofing Alliance lists steel as the most common metal roofing material today, with aluminum, copper and zinc beside it and no tin. Choose the corrugated or ribbed steel panel for a tin roof.(Metal Roofing Alliance, metal roofing materials)
How many squares is a 2,000 square foot house?
More than 20. At a 6:12 pitch the roof surface over a 2,000 sq ft footprint is 2,236 sq ft, which is 22.4 squares. At 12:12 it is 2,828 sq ft, or 28.3 squares. Pitch is the difference, and it is pure geometry.
Is there a tax credit for a metal roof?
Not federally, for a 2026 installation. Roofing is not on the IRS list of qualifying property for the energy efficient home improvement credit. That credit applies only to qualifying property placed in service before December 31, 2025. State and utility programs are separate and change often, so check your own utility.
Do metal roofs get an insurance discount?
Where the product carries a UL 2218 impact classification and your carrier offers credits for it. Texas publishes a qualifying products list and says a Class 4 covering earns the highest premium credit, while each insurer sets the amount. Get the product's class in writing and tell your carrier.
Where does this metal roof price calculator get its default prices?
They are midpoints of typical 2026 US installed quotes, labelled as starting figures rather than sourced data, because no official body publishes metal roofing prices. Every rate is an input, so this metal roofing cost calculator is at its most useful when you overwrite them with the numbers on your own quotes.
