Roof Pitch

Steeper roofs have more surface area than their flat footprint. The pitch multiplier accounts for this extra material and labor difficulty.

Squares

In roofing, a "square" is a unit of area equal to 100 square feet. Most materials and labor are quoted per square.

Metal Types

Standing seam is premium and durable. Corrugated or screw-down panels are more affordable but require more maintenance over time.

What is a Roof Square?

In the roofing industry, a "square" is a standard unit of measurement equal to 100 square feet of roof area. All roofing materials and labor are quoted per square, making it the universal measurement for estimating costs.

Roof pitch (slope) is expressed as rise over run, such as 6/12, meaning the roof rises 6 inches for every 12 inches of horizontal distance. Steeper pitches require more material and labor due to the increased surface area and installation difficulty.

How to Estimate Metal Roof Cost

  1. Measure your roof's base area (flat footprint in square feet)
  2. Determine your roof pitch (typically 4/12 to 12/12)
  3. Get pricing from a local supplier per square (100 sq ft)
  4. Add waste factor for cuts, flashing, and trim (10-20% typical)
  5. Enter material and labor costs to calculate your total project cost

Example: Standing Seam Roof

Project: 2,500 sq ft home with 7/12 pitch, standing seam metal roofing

Pricing: $450/sq material, $350/sq labor, 15% waste factor

Result: 36.97 squares needed, ~$29,580 total cost

Frequently Asked Questions

How long does metal roofing last?

40-70 years with minimal maintenance. Much longer than asphalt shingles (15-20 years).

Does pitch really affect cost?

Yes. Steeper pitches require more material and labor. A 12/12 pitch costs ~41% more than flat.

What's included in waste factor?

Cuts, trim pieces, flashing, and installation losses. 10-15% is typical; 20%+ for complex roofs.

Is standing seam worth the cost?

Yes, for durability and aesthetics. It lasts longer and requires less maintenance than other metal options.

Can I install it myself?

Metal roofing installation is labor-intensive and requires roofing experience. Professional installation is recommended.

Are there cheaper metal options?

Corrugated or screw-down panels cost less but have shorter lifespans and require more maintenance.

Do metal roofs reduce energy costs?

Yes. Reflective metal roofs reduce cooling costs 20-30% in hot climates. Heating savings vary by region.

What warranties do they offer?

Most quality metal roofs come with 20-50 year warranties covering material defects and workmanship.
