How to use the metal roof cost calculator
Four quick steps turn your house size, pitch and panel choice into roof area, material and labor cost, a total price, cost per square foot and a side-by-side comparison with asphalt — with a slope check, a roof plan, by-type and by-pitch tables, charts and a downloadable report.
Enter the roof size
Give the house length, width and overhang — or drop in a known roof area from a quote.
Set pitch & style
Enter the roof pitch and choose a gable or hip roof; the slope factor and labor markup follow.
Pick the metal system
Choose exposed fastener, standing seam or metal shingles, the metal and gauge, and the rates.
Read results & save a PDF
Get material, labor and total cost, per-sq-ft price, lifespan and the asphalt comparison.
How metal roof cost is calculated
The cost starts from the roof area, then layers on panels, underlayment, trim, labor (marked up on steep roofs), tear-off and extras. Here is the exact math the calculator runs.
Worked example — 50 × 30 ft house, 12″ overhang, 6/12 pitch, gable, standing-seam steel, 1 tear-off layer
Roof area: 1,664 sq ft × 1.12 ≈ 1,860 sq ft (18.6 squares) · pitch factor 1.0
Materials: panels + underlay + trim ≈ $15,300 · Labor: 1,860 × $6.25 ≈ $11,600
Tear-off: 18.6 sq × $150 ≈ $2,800 · Total ≈ $29,800
≈ $30,000 installed — about $16 per square foot, or roughly $1,600 per square, for a standing-seam steel roof that should last 40–70 years (about $540 a year).
Metal roof cost reference charts
Handy lookups for how the panel system, metal and roof pitch change the installed price, lifespan and cost per year.
| Roof type | Installed / sq ft | Est. total | Lifespan | Cost / year |
|---|---|---|---|---|
| Asphalt (architectural) | $4.50–$7.00 | ~$10,700 | 20–30 yr | ~$430 |
| Exposed-fastener steel | ~$8.48 | ~$15,800 | 30–45 yr | ~$420 |
| Metal shingles (steel) | ~$13.18 | ~$24,500 | 40–60 yr | ~$490 |
| Standing seam (steel) | ~$16.00 | ~$29,800 | 40–70 yr | ~$540 |
| Standing seam (aluminum) | ~$18.62 | ~$34,600 | 40–70 yr | ~$630 |
| Standing seam (copper) | ~$39.46 | ~$73,400 | 60–100 yr | ~$920 |
Metal costs more up front than asphalt, but over its much longer life the cost per year narrows sharply — exposed-fastener steel can even beat asphalt per year. Figures are mid-range national ballparks; use local quotes.
| Pitch | Labor factor | Roof area | Est. total | Per sq ft | Slope |
|---|---|---|---|---|---|
| 3/12 | 1.00 | 1,715 sq ft | ~$27,500 | ~$16.02 | OK |
| 4/12 | 1.00 | 1,754 sq ft | ~$28,100 | ~$16.01 | OK |
| 6/12 | 1.00 | 1,860 sq ft | ~$29,800 | ~$16.00 | OK |
| 8/12 | 1.15 | 2,000 sq ft | ~$33,800 | ~$16.91 | OK |
| 10/12 | 1.30 | 2,166 sq ft | ~$38,600 | ~$17.83 | OK |
| 12/12 | 1.30 | 2,353 sq ft | ~$41,900 | ~$17.81 | OK |
Steeper roofs cost more two ways: more area for the same footprint, and a labor markup above 7/12 for roof jacks and harnesses. Standing seam clears every pitch here; exposed-fastener panels need 3/12 or more.
| System | Look | Best for |
|---|---|---|
| Exposed fastener | Corrugated / R-panel ribs | Barns, sheds, budget builds |
| Standing seam | Raised seams, hidden clips | Premium homes, low slopes |
| Metal shingles | Shingle, shake or tile look | Curb appeal, HOA areas |
Exposed-fastener screws go through the panel face (cheapest); standing seam hides its fasteners (premium, no face penetrations); metal shingles mimic traditional roofing.

Metal roof cost calculator FAQ
Quick answers about metal roof pricing, systems, pitch, lifespan and whether it’s worth it.
Installed metal roofs typically run about $8 to $16 per square foot for steel, and more for aluminum or copper. A standing-seam steel roof on a 50 × 30 ft house (about 1,860 sq ft) works out to roughly $30,000 installed, or about $16 per square foot, including tear-off, underlayment and trim.
Exposed-fastener steel on the same roof is closer to $16,000.
A metal roof costs more up front — often two to three times an asphalt roof — but lasts far longer. Architectural shingles run about $4.50 to $7 per square foot installed and last 20 to 30 years, while steel metal roofs last 40 to 70 years.
Spread over its life, a metal roof’s cost per year can be competitive, and it adds resale value.
Exposed-fastener steel panels (corrugated or R-panel) are the cheapest metal roof, often around $8 per square foot installed.
Standing seam is the premium residential option at roughly $14 to $18 per square foot, and copper is the most expensive by far.
Exposed-fastener panels are screwed through the face of the panel — cheaper and common on barns and budget homes, but the rubber washers need attention over time.
Standing seam hides its fasteners under raised seams with concealed clips, so there are no face penetrations; it costs more but is the premium, longest-lasting look for houses.
Yes, in two ways. A steeper roof has more surface area for the same footprint, and above about 7/12 crews need roof jacks and harnesses, so labor is marked up (about 15% from 7/12 to 9/12 and 30% above that).
Standing seam also works on very low slopes down to a quarter-in-12, where lapped panels can’t go.
Steel and aluminum metal roofs typically last 40 to 70 years, metal shingles 40 to 60, and copper 60 to 100 years or more.
That’s roughly double the life of an asphalt-shingle roof, which is one of the main reasons people choose metal.
Some codes allow metal over a single layer of shingles, which saves on tear-off, but most contractors recommend a full tear-off so they can inspect and repair the decking and install underlayment properly.
Removal runs about $100 to $200 per roofing square per layer.
In snowy climates, yes. Snow sheds off a metal roof in sudden sheets, so snow guards along the eaves hold it back over doors, walkways and decks.
They’re usually spaced about one every 2 ft of eave at roughly $15 each.
Planning estimate only — get local quotes. Prices are typical national ballpark figures in US dollars and vary widely by region, contractor, steel prices, roof complexity and access — replace the material and labor rates with your own quotes. Roof area = footprint × √(1 + (pitch÷12)²), and 1 roofing square = 100 sq ft. Labor is marked up on steep roofs, and lifespan and cost-per-year figures are typical ranges. Minimum slopes follow common building-code rules (exposed-fastener panels and metal shingles 3/12, standing seam ¼:12); always follow the panel maker’s instructions and your local code.
