To calculate metal roofing cost, you need to measure your roof size in square feet, pick your metal material type, and multiply the cost per square foot by your total roof area. Metal roofing is one of the most durable roof options available, lasting 40 to 80 years. The total price depends on the material you choose, your roof size, and labor costs. Most homeowners pay between $5,000 and $15,000 for a metal roof replacement. According to RubyHome, metal roofing installation costs range from $10.00 to $17.05 per square foot for standing seam metal panels. Understanding these numbers helps you budget for your roof project.

What Size Is Your Roof?

Start by finding your roof size in square feet. The average U.S. roof size is 2,647 square feet, according to the National Association of Home Builders. You can measure your roof from the ground using a ladder, or ask a contractor to help you get an exact measurement.

Roof size is often called “squares” in the roofing industry. One square equals 100 square feet. So a 1,700 square foot roof is 17 squares. If you have a 2,000 square foot roof, that is 20 squares.

Which Metal Material Costs the Most?

Metal roofing comes in many types, and each one costs different amounts per square foot. Here are the main types and their prices.

Metal TypeCost Per Sq. Ft.
Corrugated Metal$5.50, $11.50
Standing Seam Metal Panels$10.00, $17.05
Steel Shingles$8.00, $12.65
Copper Tiles$21.00, $39.70

Copper is the most expensive metal option. Standing seam panels are popular for homes and businesses because they last so long and look clean.

How Do You Do the Math?

The calculation is simple: Roof Size × Cost Per Sq. Ft. = Total Cost. For example, a 2,000 square foot roof with standing seam metal at $13 per square foot would cost $26,000. Add labor costs on top of material costs.

According to RubyHome, total roof installation costs range from $4 to $40 per square foot, depending on your material and location. For a 1,700 square foot roof, you might pay $6,800 to $68,000 total. Labor usually adds $3 to $10 per square foot to your material cost.

What Else Affects Your Final Price?

Many things change your metal roofing cost. Your roof pitch, or steepness, affects how long installation takes. Steeper roofs cost more because workers need safety gear and more time.

Metal roofing lasts 40 to 80 years, according to industry data. This long life makes metal a good value over time. Only 10% of U.S. homes use metal roofing today, but more homeowners choose it each year because it saves energy and handles storms well.
