If you're putting a new roof on your Maine home, the choice usually comes down to two options: asphalt shingles or metal. Both work in Maine. They just work differently, and one is probably a better fit for your situation than the other.
Here's a straight comparison from our crew at Best Maine Construction, who's installed plenty of both.
Lifespan: How Long Each Lasts in Maine
This is the biggest practical difference between the two.
01Asphalt Shingles
Asphalt shingle roofs in Maine usually last 20 to 30 years. Architectural shingles, which are thicker and heavier, tend to last on the longer end of that range. Three-tab shingles are cheaper but wear out faster, especially with Maine's freeze thaw cycles.
02Metal Roofing
Metal roofs commonly last 40 to 50 years or more in Maine. Standing seam systems can run even longer with minimal maintenance. The metal itself doesn't crack, curl, or lose granules the way asphalt does.
Cost: Up Front vs Long Term
Metal costs more up front. Asphalt is more affordable to install. But the math gets more interesting when you look at the long term.
- If you replace an asphalt roof every 25 years, you'll likely replace it twice in the lifetime of one metal roof.
- Metal often pays back for homeowners who plan to stay in the home long term.
- Asphalt usually makes more sense for short-term ownership or tighter budgets.
How Each Handles Maine Winter
Snow, ice, and freeze thaw cycles are tough on every roof. Each material handles them differently.
01Snow Shedding
Metal sheds snow faster and more cleanly than asphalt. That's a real benefit in Maine, where heavy snow loads can stress a roof structure. Just be aware that sliding snow can damage gutters or anything below the eaves, so planning matters.
02Ice Dams
Metal helps with ice dams because the slick surface doesn't hold snow long. Asphalt doesn't prevent ice dams. With either material, the real fix is attic insulation and ventilation, but metal does have an edge.
03Freeze Thaw Stress
Asphalt shingles get brittle in extreme cold and can crack with repeated freeze thaw cycles. Metal flexes more naturally and doesn't suffer the same wear.
Looks and Curb Appeal
Both look good. They just look different.
- Asphalt shingles offer a traditional look that fits most Maine homes.
- Architectural shingles add dimension and a higher-end appearance.
- Metal roofing comes in standing seam, ribbed, and shingle profiles, and in many colors.
- Some buyers prefer asphalt; others find metal more striking. It's a personal call.
Other Things to Consider
A few practical factors that come up often.
01Noise
People worry that metal roofs are loud in rain. With proper underlayment and attic insulation, the difference is small. You probably won't notice it from inside the house.
02Energy Efficiency
Light-colored metal reflects sun and can cut cooling costs in summer. In Maine, that benefit is modest, but it's there.
03Resale Value
A new roof of either type boosts resale value. Metal sometimes commands a small premium because buyers know they won't need to replace it.
