Metal Roof Calculator
Estimate panels, fasteners, weight and cost for six metal roofing styles and four materials.
Roof Summary

Cost Estimate
Calculation Assumptions
Metal roofs are quoted by the square (100 sq ft) but sold either as full panel lengths (standing seam, corrugated) or boxes/bundles (stone-coated, shingles, tiles, slate). Each style keeps its own coverage width or box coverage. Fastening method only changes labor and fastener hardware, not the base material price.
What This Metal Roof Calculator Does
This tool estimates the roof surface area, panel or box counts, fasteners, weight, and total cost for six common metal roof styles — standing seam, corrugated, stone-coated steel, metal shingles, metal tiles, and metal slate — using four materials: steel (galvalume), aluminum, zinc, and copper.
Metal roof cost varies widely because two things change the price per square foot before labor is even added: the material you choose, and the profile you install. Corrugated steel panels are the most economical, while standing seam, tile, and slate profiles cost more per square foot for the same metal.

How Much Does a Metal Roof Cost?
A typical installed metal roof runs roughly $4 to $30 per square foot, depending on the metal and style. The main cost drivers are:
- Material — the metal itself is the biggest factor. Galvalume steel is the most affordable; aluminum, zinc, and copper cost progressively more.
- Style / profile — corrugated is the cheapest profile, standing seam the premium panel system, and tile and slate profiles add labor and hardware.
- Pitch and area — a steeper roof means more surface area for the same footprint, plus extra framing and safety work.
- Labor and region — local labor rates, weather, and roof complexity move the installed price more than the material price alone.
- Trim and details — flashing, ridge caps, valleys, eaves, gable trim, fasteners, and underlayment add up and are included in most quotes.
| Material | Typical installed cost (per sq ft) | This calculator's material default (per sq ft) |
|---|---|---|
| Steel (galvalume) | $4 – $9 | $3.50 – $6.05 |
| Aluminum | $7 – $13 | $5.50 – $9.50 |
| Zinc | $12 – $18 | $9.50 – $16.42 |
| Copper | $18 – $30 | $14.50 – $25.06 |
Installed ranges are general national estimates and vary by region, pitch, and contractor. The calculator's defaults are material-only prices: it applies each material's base cost, multiplies it by the selected style factor (1.00 for corrugated up to 1.60 for metal tiles) and a fastening factor, then adds fasteners, waste, and any price you enter.
Metal Roof Cost FAQ
How much does it cost to install a metal roof?
For a typical home, installed metal roofing usually lands between $4 and $30 per square foot, or about $400 to $3,000 per square (100 sq ft), before tear-off of an existing roof. The total depends mainly on the metal chosen (steel is cheapest, copper most expensive), the profile (corrugated under standing seam under tile and slate styles), roof pitch, and local labor rates.
Is metal roofing more expensive than asphalt shingles?
Yes, upfront. A metal roof typically costs two to three times more than architectural asphalt shingles on the same house. Over its full life the gap narrows: asphalt shingles last 20 to 30 years while a galvalume steel roof commonly lasts 40 to 60 years, so the cost per year can be comparable, especially on steep roofs where re-roofing labor is expensive.
What affects metal roof installation cost the most?
The material and the profile drive most of the difference, followed by labor. Choosing copper instead of steel, or standing seam instead of corrugated, changes the price per square foot more than any other single decision. After that, roof pitch, dormers, valleys, and local labor rates add the most — a steep, complex roof can increase cost by 30% to 50% over a simple low-pitch roof.
Which metal roofing material is cheapest?
Galvalume steel is the least expensive metal roofing material, and corrugated is the least expensive profile. In this calculator, corrugated steel defaults to about $3.50 per square foot of material before fasteners and waste. Aluminum costs more but weighs less and resists coastal corrosion; zinc and copper are premium materials with much higher prices.
How long does a metal roof last relative to its cost?
Galvalume steel typically lasts 40 to 60 years, aluminum and zinc 50 to 80 years, and copper can exceed 100 years. Because the most expensive materials last longest, the cost per year of service is often similar across metals. Installation quality — fastener choice, flashing, and proper seams — matters as much as the metal itself for reaching that lifespan.
