Metal Roof vs. Asphalt Shingles

A metal roof lasts a lifetime — Interlock aluminum is engineered to never re-roof — versus roughly 15-20 years for asphalt shingles. Metal costs more upfront but eliminates repeat replacements, sheds snow, resists wind and fire, and is recyclable. Over a metal roof's life, asphalt is typically replaced two to four times.

The honest comparison isn't the day-one price — it's the cost and performance over the time you own your home.

The lifetime-cost math

Because asphalt is replaced every 15-20 years, a homeowner staying long-term pays for multiple roofs — plus tear-off and disposal each time. A single Interlock aluminum roof removes that cycle and the recurring disruption.

FAQs

Common questions

Is a metal roof worth it compared to asphalt?

For homeowners staying long-term it usually is — one lifetime roof instead of two to four asphalt replacements, plus better snow shedding, wind and fire resistance, and resale value.

Are metal roofs noisy in the rain?

No. Over solid decking and underlayment, a properly installed metal roof is no louder than asphalt; the "tin roof" myth comes from bare barns without decking.
