Asphalt vs Metal vs Synthetic Shingles: What's Best for Minnesota Weather

Minnesota is one of the harder climates in the country to roof. A single year can bring hail in July, 70-mph straight-line winds, ice dams in February, and a freeze-thaw cycle that runs dozens of times each spring. Material choice matters more here than it does in a mild climate.

We install asphalt, metal, and synthetic roofing on homes across Minnetonka, Orono, and Hopkins. None of the three is universally best. Here's an honest look at how each handles our weather.

Asphalt shingles: the practical default

Architectural asphalt shingles are on the majority of houses in the west metro for good reason. They're cost-effective, widely stocked, quick to install, straightforward to repair, and they come in impact-resistant grades that matter in hail country.

Where asphalt wins

• Best cost-to-performance ratio of the three, by a wide margin.
• Damaged sections can be repaired without redoing the whole roof.
• Impact-resistant classes can reduce hail damage and sometimes affect insurance premiums.
• Colors and profiles that fit almost any neighborhood, including HOA-heavy areas.

Where asphalt gives ground

Asphalt has the shortest service life of the three, and it's the most sensitive to poor attic ventilation. A hot, under-vented attic will age shingles from the underside — which is why we treat ventilation as part of the roof, not an add-on.

Metal: long life and excellent snow behavior

Standing seam metal is a strong fit for Minnesota. Snow and ice slide off it rather than sitting on the eaves, which helps with ice dam pressure. Panels shed water fast, resist wind uplift well when detailed correctly, and last a long time.

What to know before you choose metal

• Higher upfront cost than asphalt, offset by service life.
• Sliding snow needs planning — snow guards over doors, walkways, and driveways are not optional.
• Hail can dent softer metals cosmetically without affecting performance.
• Installation quality is everything: panel movement, fastener choice, and flashing details decide whether the roof performs.

Metal also pairs well with modern and lake-adjacent architecture, which is why we see more of it on homes near Lake Minnetonka and in Shorewood than in older inland subdivisions.

Synthetic: the look of slate or shake, without the weight

Synthetic roofing — engineered polymer products made to mimic slate or cedar shake — is the newest of the three families. It's light, dimensionally stable through freeze-thaw cycles, and generally more impact-tolerant than the natural materials it imitates.

Best fits for synthetic

• Homes where a slate or cedar look matters but the structure can't carry real slate.
• Steep, highly visible roof planes where appearance drives the decision.
• Owners who want a long service life and are less price-sensitive than the average replacement.

The trade-offs are cost and product variation. Quality across brands is uneven, so the specific product and its installation instructions matter as much as the category.

How Minnesota weather should drive your decision

Hail

If your block has been hit more than once, impact resistance should weigh heavily. Impact-rated asphalt and synthetic products handle strikes well; metal may dent without leaking.

Ice dams

No material prevents ice dams on its own — they're caused by heat escaping into the attic. But metal's shedding behavior plus proper ice-and-water membrane at the eaves reduces how much damage a bad winter can do.

Wind

All three can perform in high wind when installed to spec. Failures we see are almost always nailing patterns, starter courses, and edge metal — not the shingle itself.

The honest answer for most homes

For most Minnetonka and Eden Prairie homes, a quality impact-resistant architectural asphalt roof with correct ventilation and eave protection is the best value available. Metal makes sense when you plan to stay decades or have a snow-shedding problem to solve. Synthetic makes sense when appearance is the priority.

We install all three, so we have no reason to push you toward one. What we care about is that the system underneath — underlayment, flashing, ventilation — is right for your house.
