🦉 Metal vs. Asphalt: Lifetime Cost Calculator
Compare what each roof really costs per year over its life in Minnesota.
Assumes today’s installed pricing, single-layer tear-off, and typical Minnesota lifespans (hail & freeze-thaw shorten asphalt life here). 50-year totals assume asphalt is replaced at end of life at the same price — inflation would widen the gap further. Insurance, warranties, and resale value aren’t included.
Compare Options With a Free Estimate →The Edina contemporary build had a 30-year ownership horizon and a head-scratcher question. Two reroof quotes: $42,000 in premium asphalt or $94,000 in 24-gauge standing seam metal. The asphalt was less than half the price upfront. The metal was supposed to last twice as long.
The lifecycle math actually favored metal — but only because the homeowner planned to stay 30 years. Below is the honest 30-year cost comparison.

TL;DR
Bottom line: Over 30 years, premium Class 4 asphalt costs $42K install + $48K second install at year 28 + $5K maintenance = $95K. Standing seam metal costs $90K install + $0 replacement + $15K periodic maintenance = $105K. Asphalt slightly wins on 30-year math; metal wins on 50+ year horizons. For 15-year ownership horizons, asphalt wins clearly. For multi-generational ownership, metal wins clearly.
30-year cost comparison
| Item | Premium Class 4 Asphalt | 24-gauge Standing Seam Metal |
|---|---|---|
| Initial install | $42,000 | $90,000 |
| Year 28 replacement | $48,000 | $0 (still in service) |
| 30-year maintenance | $5,000 | $15,000 |
| 30-year total | $95,000 | $105,000 |
50-year math flips the answer
Asphalt: $42K + $48K (year 28) + $58K (year 56 in inflated dollars) + $10K maintenance = $158K. Metal: $90K + $20K maintenance = $110K. Standing seam metal wins by $48K over 50 years.

The decision
Metal wins if: 30+ year ownership horizon, modern or contemporary architecture, value low-maintenance for decades.
Asphalt wins if: 15-year ownership horizon, traditional architecture, prefer lower upfront cost.
