Asphalt wins the first quote. Metal often wins the forty-year math.
Up-front cost (2026, 2,000 sq ft roof, Twin Cities)
| System | Installed |
|---|---|
| 3-tab asphalt | $9,000–$14,000 |
| Architectural asphalt | $12,000–$20,000 |
| Impact-resistant (Class 4) asphalt | $16,000–$26,000 |
| Exposed-fastener metal panel | $18,000–$30,000 |
| Standing seam metal | $28,000–$55,000 |
Expected service life in Minnesota
| System | Realistic life here |
|---|---|
| 3-tab | 12–18 yrs |
| Architectural | 18–28 yrs |
| Class 4 impact | 22–30 yrs |
| Exposed fastener metal | 25–35 yrs (fasteners need service) |
| Standing seam | 40–60 yrs |
Freeze-thaw, hail, and heavy ice loading are why a "30-year shingle" often lasts 20 here.
The 40-year math
Over 40 years you buy architectural asphalt roughly twice while standing seam is a single purchase — and metal ends the period with remaining life while asphalt does not.
Where metal genuinely wins
- Snow shedding, which reduces ice-dam formation (add snow guards over doorways).
- Hail — metal dents but rarely fails; asphalt loses granules and then fails.
- Insurance — many carriers discount impact-resistant roofing. Ask your agent for the specific credit.
- Fire and wind resistance.
Where asphalt genuinely wins
- Complex roofs with many valleys and dormers, where metal labor climbs fast.
- Short holding periods — under seven years you will not recover the premium.
- Repairability — any roofer can patch asphalt.
- Neighborhood fit and HOA rules.
The honest recommendation
- Staying 15+ years, simple roof lines, ice dam history → standing seam metal.
- Staying under 10 years, or complex roof → architectural or Class 4 asphalt.
- Hail-prone area with an insurance discount → Class 4 asphalt is often the best cost-adjusted choice.
Do not forget ventilation
Neither material performs without balanced intake and exhaust ventilation. A metal roof over a poorly vented attic still gets ice dams.
We will quote your roof in both materials on the same deck, ventilation, and ice-and-water spec.

Frequently asked questions
Is a metal roof worth it in Minnesota?
If you are staying 15 or more years, have simple roof lines, or fight ice dams, standing seam metal usually justifies the premium through 40 to 60 year service life and snow shedding.
How much more does a metal roof cost than asphalt?
Standing seam typically runs two to three times architectural asphalt, roughly $28,000 to $55,000 versus $12,000 to $20,000 on a 2,000 square foot Twin Cities roof.
Does a metal roof prevent ice dams?
It reduces them by shedding snow, but ice dams are caused by attic heat loss, so air sealing, insulation, and balanced ventilation are still required.
