Metal Roof vs Shingles — Which Is Better?
Metal roofs cost 2-3x more upfront ($10-$18/sq ft vs $4-$7 for shingles) but last 2-3x longer (40-70 years vs 20-30), reduce energy bills 10-25%, withstand 140 mph winds, and are fire-resistant. Choose metal if staying 10+ years. Choose shingles if selling soon, on a tight budget, or in an HOA that restricts metal.
Cost Breakdown
| Service | Low | High | Notes |
|---|---|---|---|
| Asphalt shingles (installed) | $8,000 | $14,000 | 2,000 sq ft roof |
| Metal standing seam | $20,000 | $36,000 | 2,000 sq ft roof |
| Metal corrugated | $10,000 | $20,000 | Budget metal option |
| Shingle lifespan | 20 | 30 | Years |
| Metal lifespan | 40 | 70 | Years |
| Energy savings (metal) | 10% | 25% | Annual cooling |
Metal Roof vs Asphalt Shingles
Head-to-Head Comparison
| Metal | Asphalt Shingles | |
| Cost (2,000 sq ft) | $20,000-$36,000 | $8,000-$14,000 |
| Lifespan | 40-70 years | 20-30 years |
| Wind resistance | 140 mph | 60-110 mph |
| Fire rating | Class A (non-combustible) | Class A-C |
| Energy savings | 10-25% | Minimal |
| Maintenance | Very low | Moderate |
| Resale value added | 1-6% | Standard |
| Noise (rain) | Slightly louder | Quiet |
| Hail resistance | Good-Excellent | Fair-Good |
Cost Per Year of Protection
The real comparison: metal costs $0.29-$0.51 per sq ft per year of protection. Shingles cost $0.16-$0.35 per sq ft per year. Metal is only slightly more expensive when measured by lifespan — and saves money on energy and maintenance.
When Metal Wins
- Last house — you never want to roof again
- Storm-prone areas (hurricanes, hail, wildfires)
- Hot climates — reflective metal reduces cooling costs significantly
- Steep or complex roofs — metal handles water shedding better
When Shingles Win
- Selling within 5-10 years — you won't recoup the full metal premium
- Tight budget — half the upfront cost
- HOA restrictions on metal roofing
- Aesthetic preference for traditional look
Related Questions
Are metal roofs noisy in the rain?
With proper underlayment and attic insulation, metal roofs are only slightly louder than shingles — barely noticeable inside the home. The noise difference is most apparent in buildings without insulation (barns, carports).
Do metal roofs rust?
Modern metal roofing (galvanized steel, aluminum, Galvalume) does not rust. Steel roofs have zinc or aluminum coatings that prevent corrosion. Aluminum and copper are naturally corrosion-resistant. Scratches should be touched up to maintain the coating.
Can you walk on a metal roof?
Yes, carefully. Walk on the flat areas near the supports (not the raised seams). Metal roofs are slippery when wet. Wear soft-soled shoes. For maintenance and repairs, most professionals use roof brackets and harnesses.
