Asphalt vs. Metal Roofing in the Mountain West

The Mountain West's hail, wind, snow, and altitude UV punish roofs harder than almost anywhere. How the two most popular materials actually hold up here — and what each really costs over time.

The Mountain West stress test

A roof across the region faces four compounding threats: hail (the big one), windstorms that gust past 60 mph, heavy wet mountain snows, and UV exposure roughly 25 percent stronger than at sea level. Materials that perform identically in a catalog diverge quickly under that load — so national comparisons mislead here.

Asphalt shingles: the value default

Asphalt remains the most common choice across Mountain West metros for good reason: the lowest installed cost, every roofer knows it, and repairs are simple and cheap. The high-country catch is lifespan. A '30-year' architectural shingle in the region realistically delivers 15 to 20 years — altitude UV embrittles the asphalt and each hail season takes granules with it. If you choose asphalt here, choose Class 4 impact-rated shingles: they resist bruising dramatically better, and many regional insurers discount premiums enough to repay the upgrade within several years.

Metal roofing: the endurance play

Standing-seam steel costs roughly two to three times asphalt installed, and stone-coated steel sits between. What that buys in the Mountain West: a 40-to-60-year service life, hail resistance that usually means cosmetic dents rather than functional failure, wind ratings far beyond regional gusts, and snow that sheds rather than accumulates (plan for snow guards above doorways). Metal also reflects summer heat, trimming cooling costs in increasingly hot high-desert summers.

The honest downsides of metal

• Cosmetic denting. Large hail can dimple metal panels. The roof still works, but some policies exclude cosmetic metal damage — read that endorsement before buying.
• Fewer qualified installers. Standing-seam is a specialty; a bad metal install leaks at every panel. Vet experience specifically.
• Repair complexity. Replacing one damaged panel is more involved than swapping shingles.

The math that decides it

Asphalt wins if you will sell within ten years or budget is the binding constraint — buyers reward a new roof regardless of material. Metal wins if this is your long-term home: one metal roof can outlast two to three asphalt roofs, and across the Mountain West the avoided tear-offs, claims, and deductibles compound. Either way, install quality and proper ice-and-water shield detailing at eaves and valleys matter more than brand — the region's freeze-thaw cycles find every shortcut.
