Choosing between a metal roof and an asphalt shingle roof is one of the most common questions Maine homeowners ask when planning a roof replacement.
Both roofing systems perform well when properly installed, but they offer different advantages depending on your home’s design, budget, long-term plans, and exposure to Maine’s winter weather. Understanding how each material responds to snow, ice, wind, and changing temperatures can help you make an informed decision.

| Ice Dam Resistance | Very Good* | Good* |
| Wind Resistance | Excellent | Very Good |
| Maintenance | Low | Moderate |
| Initial Investment | Higher | Lower |
| Appearance | Modern and traditional styles available | Traditional residential appearance |
How Snow Affects Each Roofing System
Heavy snowfall is a reality across Maine, making snow performance an important consideration.
Asphalt Shingle Roofs
Architectural shingles provide excellent protection during Maine winters and are designed to withstand normal snow loads when installed correctly. Because shingles have a textured surface, snow tends to remain on the roof longer. While this is not necessarily a problem, accumulated snow may require removal after particularly heavy storms or when recommended by a roofing professional.
Metal Roofs
Standing seam metal roofing has a smooth surface that allows snow to slide off more easily as temperatures fluctuate. This natural snow shedding can reduce prolonged snow accumulation and minimize the amount of manual snow removal required on many homes. For homeowners in areas that receive significant snowfall, this is often one of metal roofing’s greatest advantages.
Which Roofing Material Handles Ice Dams Better?
Ice dams develop when heat escaping from the home melts rooftop snow. As the water reaches the colder roof edge, it refreezes and gradually creates a ridge of ice that can trap additional melting water.
Both roofing systems can experience ice dams if the underlying conditions exist. However, metal roofing often sheds snow more readily than asphalt shingles, which may reduce opportunities for prolonged snow buildup that contributes to ice dam formation. It’s important to remember that roofing material alone does not eliminate ice dams. Proper attic insulation, air sealing, and ventilation remain the most effective ways to reduce their occurrence.
Snow Guards for Metal Roofs
Because snow slides more easily from metal roofs, snow guards are often recommended to help control snow release over:
- Entryways
- Walkways
- Decks
- Driveways
- Landscaping
- Utility equipment
Snow guards allow snow to release more gradually while helping protect people and property below.
Durability in Maine’s Climate
Both roofing materials are designed to withstand Maine’s weather, but they age differently over time.
Metal Roofing
Standing seam metal roofing performs exceptionally well against:
- Heavy snow
- Ice
- Wind
- Moisture
- Freeze-thaw cycles
Routine inspections and occasional maintenance help ensure long-term performance.
Architectural Asphalt Shingles
Modern architectural shingles are engineered for excellent weather resistance and remain one of the most popular roofing choices throughout Maine. High-quality shingles installed according to manufacturer specifications provide dependable protection for decades.
Which Roof Costs More?
Metal roofing typically requires a larger initial investment than asphalt shingles. However, because metal roofs often last significantly longer, some homeowners view them as a long-term investment, particularly if they plan to remain in their home for many years.
Architectural shingles remain an excellent value for homeowners seeking durable protection with a lower upfront cost. A professional estimate can help compare both options based on your home’s size, roof complexity, and long-term goals.
Choosing the Right Roof for Your Home
A metal roof may be a good choice if you:
- Plan to stay in your home for many years.
- Prefer a low-maintenance roofing system.
- Want exceptional longevity.
- Live in an area that regularly experiences heavy snowfall.
Architectural asphalt shingles may be the better fit if you:
- Prefer a more traditional residential appearance.
- Want a lower initial investment.
- Need a roofing solution that performs well while fitting your budget.
Both roofing systems can provide decades of reliable protection when installed by an experienced roofing contractor.
Which Roofing Material Is Best Along Maine’s Coast?
Homes near Maine’s coastline face additional exposure to wind, moisture, and salt air. Both standing seam metal roofing and high-quality architectural shingles can perform well in coastal environments when appropriate materials and installation methods are used. Selecting corrosion-resistant materials and following manufacturer installation requirements are especially important for coastal properties.

Frequently Asked Questions
Is a metal roof worth it in Maine?
Many homeowners choose metal roofing because of its exceptional longevity, durability, and ability to shed snow more readily than traditional roofing materials. Whether it’s the right investment depends on your budget and how long you plan to own your home.
Do metal roofs prevent ice dams?
Metal roofing may help reduce snow accumulation, but it does not eliminate the underlying causes of ice dams. Proper attic insulation, ventilation, and air sealing remain essential.
Are metal roofs noisy during rain or snow?
Not typically. Modern residential metal roofing is installed over solid roof decking with underlayment, which significantly reduces sound transmission.
Can a metal roof be installed over existing shingles?
In some cases, it may be possible. However, removing the existing roofing allows the roof deck to be inspected for damage before the new roofing system is installed. Your roofing contractor can recommend the best approach for your home.
Which roof lasts longer in Maine?
Standing seam metal roofs generally have the longest expected lifespan, often lasting 40 years or more. Architectural asphalt shingles typically provide reliable performance for 25 to 35 years when properly installed and maintained.
