Asphalt shingles vs. metal roof: cost, lifespan, ROI compared
Side-by-side comparison of asphalt shingles vs metal roofing for homeowners. Cost per square foot, 30-year ROI, energy savings, insurance discounts, resale value.
The choice comes down to three questions: how long will you stay in this house, what does your insurance company pay for, and how much do you care about a 30-year vs 60-year roof? Let's break it down.
The headline numbers
| Architectural asphalt shingle | Standing-seam metal | |
|---|---|---|
| Cost (2,300 sqft installed) | $13,000–$18,000 | $22,000–$32,000 |
| Lifespan | 25–30 years | 40–70 years |
| Cost per year of life | $520–$720 | $315–$800 |
| Install time | 1–2 days | 3–5 days |
| Wind rating | 110–130 mph | 140–160 mph |
| Energy savings vs asphalt | — | 10–25% on AC bills |
| Insurance discount | — | 5–25% in storm markets |
| Resale ROI (national avg) | 61% | 48–61% |
When asphalt wins
Choose architectural asphalt if any of these apply:
- You'll move in <15 years. You won't recover the metal premium. The roof outlives you in this house.
- Tight budget. Asphalt is roughly 60% of the metal price. The savings can fund a kitchen remodel.
- HOA restrictions. Many HOAs in older neighborhoods require asphalt shingle for visual consistency.
- Mild climate, no hail. The lifespan gap matters less when there's no extreme weather to test it.
- You want it done fast. 1–2 days vs 3–5. Less time exposed if rain's in the forecast.
When metal wins
Choose standing-seam metal if any of these apply:
- You'll stay 20+ years. The cost-per-year-of-life math swings hard in metal's favor at 30+ year ownership.
- You live in a hail / hurricane / wildfire zone. Insurance discounts of 15–25% can pay back the upfront premium in 6–8 years.
- Your AC bills are over $250/mo in summer. A reflective metal roof can shave 15–25% off cooling costs. In Phoenix or Houston that's real money.
- You want minimal maintenance. No granule loss, no missing tabs after a windstorm, no algae stains.
- You want a contemporary aesthetic. Standing-seam reads as “modern farmhouse” — and that's currently boosting resale by 4–8% in design-forward markets.
The 30-year ownership math
Imagine a 2,300 sqft roof. Asphalt route: install at year 0 ($15,500), reroof at year 28 ($21,000 in 2054 dollars). Total spend in 30 years: $36,500.
Metal route: install at year 0 ($27,000). Still going strong at year 30. Total spend: $27,000. Plus ~$200/year in AC savings = $6,000 saved. Plus insurance discount ~$300/year = $9,000 saved.
Net 30-year savings on metal: roughly $24,500 if you stay the full 30 years.
The myths to ignore
- “Metal roofs are loud in the rain.” Modern metal roofs go over solid decking + underlayment. They're quieter than asphalt, not louder.
- “Metal attracts lightning.” No. Lightning targets the tallest object regardless of material. Metal actually safely conducts a strike to ground without igniting.
- “Metal dents easily.” 24-gauge steel (the spec for residential standing-seam) handles up to 2" hail. Aluminum dents more easily — that's the version most complaints come from.
- “Metal makes the house hot.” Opposite. Modern metal roofs have reflective coatings (“cool roof” rated) that bounce solar heat — they reduce attic temp by 10–25°F.
The quick decision matrix
- Staying <15 years + tight budget → architectural asphalt
- Staying 25+ years + hail/storm zone → metal
- Staying 25+ years + hot southern climate → metal
- Forever home + budget allows → metal
- Selling within 5 years → asphalt (don't over-invest)
