Metal roof cost calculator: price per square foot by roof size (2026)
Standing-seam metal costs $8–$18 per sq ft installed in 2026 — $17,900–$40,200 for a 2,000 sq ft home. Cost table by roof size, the calculation, what moves the price, and the 30-year math vs asphalt.
A standing-seam metal roof costs $8–$18 per square foot installed in 2026 — about $17,900–$40,200 for a typical 2,000 sq ft home. That is roughly double asphalt up front, and often cheaper over 30 years. Here is how to calculate your own number and what moves it.
Metal roof cost by roof size
Figures assume a 6/12 pitch (surface = footprint × 1.118) and 24-gauge standing seam steel, installed.
| Home footprint | Roof surface | Low ($8/sq ft) | Mid ($13/sq ft) | High ($18/sq ft) |
|---|---|---|---|---|
| 1,500 sq ft | 1,677 sq ft | $13,400 | $21,800 | $30,200 |
| 2,000 sq ft | 2,236 sq ft | $17,900 | $29,100 | $40,200 |
| 2,500 sq ft | 2,795 sq ft | $22,400 | $36,300 | $50,300 |
| 3,000 sq ft | 3,354 sq ft | $26,800 | $43,600 | $60,400 |
How to calculate your metal roof cost
- Measure the footprint — or let a roof area calculator trace it from satellite.
- Multiply by your pitch factor (4/12 → 1.054, 6/12 → 1.118, 8/12 → 1.202). Steeper roofs have more roof.
- Add 10% waste for panels cut around valleys and penetrations.
- Multiply by the installed rate for your panel type and region.
- Add tear-off ($1.00–$2.00 per sq ft), flashing and trim package, and permits.
What moves the price
- Panel type. Exposed-fastener (corrugated, R-panel) runs $5–$9 per sq ft; standing seam $8–$18; stone-coated steel shingles $9–$14.
- Metal. Galvalume steel is the value pick. Aluminum adds 20–30% (coastal homes need it). Copper and zinc are $20–$40 per sq ft.
- Gauge. 24-gauge is the residential standard and handles 2-inch hail; 26- and 29-gauge are cheaper and dent.
- Complexity. Hips, valleys, dormers and skylights mean more cuts, more trim and more hours.
- Region. Labor is the swing: coastal metros run 20–35% over the national average; the rural Midwest and Southeast 15–25% under.
Metal vs asphalt: the 30-year math
On a 2,000 sq ft home, architectural asphalt costs about $12,900 installed and lasts 25–30 years. Metal costs about $29,100 and lasts 40–70 years. Over 30 years the asphalt route needs a second roof; the metal route does not, and typically saves 10–25% on summer cooling plus 5–25% on insurance in storm states. If you will own the home 20+ years, metal usually wins. If you will sell within 10, asphalt does. Full comparison: asphalt vs metal.
Frequently asked questions
How much does a metal roof cost per square foot in 2026?
$8–$18 installed for standing seam steel; $5–$9 for exposed-fastener panels; $20–$40 for copper or zinc.
Is a metal roof worth the cost?
Usually yes for a long-term home in a hail, hurricane, wildfire or hot-summer climate; usually no if you plan to sell within a decade, because resale recovers only 35–55% of the premium.
Can metal go over existing shingles?
Often yes where code allows one existing layer, saving the tear-off. Ask whether your roofer will still inspect and repair the decking first — that is the part that matters.
How long does a metal roof last?
40–70 years for steel standing seam; copper and zinc can exceed 80.
