Metal Roof vs. Asphalt Shingles
The honest comparison for mountain country — lifespan, cost, snow, fire, and resale, and the times each one actually makes sense.
Same roof, two very
different decades.
| Factor | Metal Roof | Asphalt Shingles |
|---|---|---|
| Lifespan (Inland NW) | 50–70 years | 15–20 years |
| Upfront cost | Higher | Lower |
| Cost over 50 years | One roof | 3–4 roofs |
| Snow shed | Sheds in controlled sheets | Grips & accumulates |
| Fire rating | Class A (non-combustible) | Varies; can ignite from embers |
| Wind resistance | Up to 140+ mph | Tabs lift & tear |
| Energy (summer) | Reflects heat, ~25% cooling savings | Absorbs heat |
| Maintenance | Virtually none | Ongoing; granule loss |
| Warranty | 30–50 yr material | Prorated, shorter |
| Resale ROI | 85–95% | Lower, expected |
| Recyclable | 100% recyclable, 25–95% recycled | Landfill (11M tons/yr US) |
Figures reflect typical Inland Northwest performance; individual products and installations vary. Metal advantages assume a properly installed system.
At 15–20 years per asphalt roof, most owners re-roof 3–4 times in the span of a single metal roof. Once you add tear-off, disruption, and rising material costs each cycle, one standing seam roof usually costs less than the shingles it replaces. Run your own numbers with our cost guide.
Is a metal roof really worth it over asphalt shingles?
In the Inland Northwest, usually yes. Asphalt lasts 15–20 years and gets replaced 3–4 times over a typical ownership window, while one metal roof lasts 50–70 years. Add the snow, fire, and insurance advantages and metal typically wins on lifetime value — see our cost guide for the numbers.
How much more does metal cost than shingles upfront?
Roughly 2–3× the upfront cost of a basic asphalt roof, depending on the metal system. Exposed-fastener panels narrow that gap considerably; standing seam is the premium end. The gap closes fast once you count re-roofs.
Which is better for heavy snow?
Metal, clearly. Its smooth surface sheds snow in controlled sheets before loads become dangerous, protecting your structure and gutters. Asphalt's rough surface grips snow and lets it build up. We add snow guards where controlled release matters.
Is metal better for wildfire areas?
Yes. Metal carries a Class A fire rating and is non-combustible — it won't ignite from wind-blown embers the way asphalt or wood shake can. Many carriers offer premium discounts for Class A roofs in wildfire zones. See our snow load & fire rating page.
When does asphalt still make sense?
When upfront budget is the hard constraint and you don't expect to own the home long. For a barn or short-term hold, asphalt or exposed-fastener metal can be the practical call. We'll tell you honestly which fits your situation.
Is a metal roof noisy in rain?
No — a modern metal roof installed over solid decking and underlayment is no louder than shingles. The “tin roof in the rain” myth comes from bare panels over open framing on old barns.
