💰 Cost Breakdown
| Item | Low | Average | High |
|---|---|---|---|
| Galvanized Steel Corrugated Panels (26-gauge) Standard galvanized steel with zinc coating. Most economical option. Best for simple roof profiles with long, straight runs. 40–50 year expected life. | $4 | $6 | $8 |
| Galvalume Corrugated Panels (26-gauge) Steel coated with aluminum-zinc alloy. Better corrosion resistance than galvanized, especially in coastal and humid climates. 50–60 year expected life. | $5 | $7 | $10 |
| Pre-Painted Corrugated Panels Factory-applied Kynar/PVDF finish in 20+ color options. Costs more upfront but eliminates repainting for 30+ years. Best for visible residential applications. | $6 | $8 | $12 |
| Corrugated Aluminum Panels Lightweight, rust-proof option for coastal environments. Dents more easily than steel but never corrodes. Good for structures where weight is a concern. | $7 | $9 | $13 |
| Old Roof Tear-Off and Disposal Removing existing asphalt shingles before metal installation. Required if the existing roof has two layers or the decking needs inspection/repair. | $1 | $2 | $3 |
| Full Installation — 2,000 sq ft Roof Complete corrugated metal roof installation including panels, underlayment, trim, flashing, fasteners, ridge caps, and labor. Excludes tear-off. | $10,000 | $15,000 | $22,000 |

📊 Factors That Impact Cost
Metal Type and Gauge
High Impact26-gauge galvanized is the budget baseline. Moving to Galvalume adds 15–20%. Dropping to heavier 24-gauge steel adds 20–30% but increases dent resistance and lifespan. Aluminum costs 30–50% more than steel.
Roof Pitch and Complexity
High ImpactCorrugated panels excel on simple gable roofs with long, straight runs. Each hip, valley, or dormer adds trim work and cutting waste. A complex roofline can add 25–40% to labor costs compared to a simple gable.
Fastener System
Medium ImpactExposed-fastener corrugated panels are standard and cheapest. Concealed-fastener corrugated systems cost 20–30% more but eliminate the most common leak point — rubber washer degradation around exposed screws.
Underlayment Choice
Medium ImpactSynthetic underlayment ($0.50–$0.75/sq ft) is standard. Peel-and-stick ice-and-water shield at eaves and valleys adds $1.50–$2.50/sq ft for those areas. In snow country, code often requires it.
Existing Roof Condition
Medium ImpactMetal can sometimes be installed over one layer of asphalt shingles using furring strips, saving $1–$3/sq ft in tear-off. If decking is rotted, replacement runs $2–$4/sq ft for new OSB or plywood.
Labor Market
Medium ImpactMetal roofing labor runs $3–$6/sq ft depending on your market. Rural areas with fewer metal roofing specialists may charge more per square foot despite lower general cost of living.
💡 Money-Saving Tips
Install over existing shingles with furring strips
If local code allows and you have only one shingle layer, installing corrugated panels over 1×4 furring strips eliminates tear-off labor and dump fees. The air gap also improves ventilation beneath the metal.
Choose galvanized over Galvalume for inland, dry climates
Standard galvanized steel performs nearly as well as Galvalume in dry, non-coastal regions. The 15–20% upcharge for Galvalume pays off in humid or salt-air environments, but not in Denver or Phoenix.
Schedule installation in winter months
Metal roofing contractors are busiest April through October. Winter scheduling (where climate allows) can net 10–15% discounts on labor. Metal panels install fine in cold weather — unlike shingles, they don't need heat to seal.
Minimize color choices per project
Ordering all panels in a single color reduces waste and may qualify for bulk pricing from the panel manufacturer. Custom or low-volume colors can add $0.50–$1.00/sq ft.
✨ When to Splurge
Upgrade to concealed-fastener panels
Exposed screws are the #1 maintenance point on corrugated roofs — rubber washers degrade in 15–20 years, requiring re-screwing of the entire roof. Concealed-fastener panels eliminate this issue entirely.
Add ridge ventilation
Metal roofs run hotter in summer than asphalt. A proper ridge vent system reduces attic temperatures by 20–30°F, lowering cooling costs and extending underlayment life.
Invest in factory-applied PVDF finish
A Kynar/PVDF coating maintains color for 30–40 years vs. 10–15 for standard acrylic paint. On a roof that lasts 50+ years, avoiding one repainting cycle ($3,000–$6,000) makes the upfront premium pay for itself.
