When it’s time to replace your roof, one of the biggest decisions you’ll face is whether to go with a metal roof or asphalt shingles. Each roofing material offers distinct advantages and potential drawbacks. The choice you make will influence not only your home’s curb appeal, but also its energy efficiency, durability, and even resale value.
In this comprehensive guide, we’ll break down all the essential differences—cost, lifespan, maintenance, environmental impact, and more—to help you make an informed decision that aligns with your budget, design preferences, and long-term goals.
What Are Asphalt Shingles?
Asphalt shingles are by far the most popular roofing material in the U.S., covering about 70% of residential roofs. Their popularity is driven by their affordability, ease of installation, and classic appearance. Typically made from a fiberglass mat coated with asphalt and ceramic granules, these shingles come in a wide variety of colors and textures.
Types of Asphalt Shingles
- 3-Tab Shingles
Flat, uniform in appearance, and the most budget-friendly option. However, they offer minimal durability and are best suited for temperate climates. - Architectural Shingles
Also known as dimensional or laminate shingles, these offer a layered, high-end look and enhanced durability—ideal for homes that need a little extra flair. - Luxury Shingles
Designed to replicate the appearance of natural slate or cedar shakes. These are more expensive but provide superior weather resistance and aesthetics.
What Is Metal Roofing?
Metal roofing is increasingly popular among homeowners for its contemporary design, exceptional longevity, and energy-saving benefits. Common materials include galvanized steel, aluminum, copper, and zinc, and they come in a variety of formats:
- Standing Seam Panels – Vertical panels with raised seams and hidden fasteners for a sleek, modern finish.
- Metal Shingles – Mimic the appearance of tile, slate, or wood while providing the performance benefits of metal.
What once was a go-to material for barns and industrial buildings is now a premium choice for homes of all styles, from modern to rustic. With so many metal roofing benefits, it should be a top choice for your replacement.
Cost Comparison
Initial Installation Costs
- Asphalt Shingles: $4–$8 per square foot
A 2,000-square-foot roof may cost between $8,000 and $16,000 installed. - Metal Roofing: $8–$16 per square foot
The same roof size might range from $16,000 to $32,000 installed.
While the initial cost of a metal roof is higher, it often pays for itself over time due to reduced maintenance, increased lifespan, and potential energy savings. Metal roofs typically last 40–70+ years, while asphalt lasts 20–30 years so it is important to consider how long you will be in your home.
Another cost consideration is insurance. Metal roofing may qualify for reduced premiums due to superior resistance to fire, hail, and high winds. With inflation rates rising in recent years, it is also worth considering how expensive a new roof replacement will be in a few decades.
Durability and Lifespan
Seattle’s moist, rainy climate and occasional snow make durability a top priority. Considering how long your roof will last is an important decision for anyone considering a new roof.
Asphalt Shingles
- Lifespan: 20–30 years
- Vulnerable To:
- High winds
- Hail
- Moss and algae growth
- UV rays and moisture damage
Frequent rain in the Pacific Northwest can lead to premature deterioration, especially if moss builds up.
Metal Roofing
- Lifespan: 40–70+ years
- Advantages:
- Withstands winds over 140 mph
- Resists moss, mildew, and insects
- Impervious to rot and moisture
- Performs well in coastal and mountainous environments
For Seattle-area homes, metal roofing provides superior durability—especially important for long-term homeowners who want to avoid future replacements.
Energy Efficiency
Metal Roofing
- Reflects solar radiant heat, cutting cooling costs by up to 40%.
- Beneficial even in milder Seattle summers to reduce attic heat buildup.
Asphalt Shingles
- Absorb more heat, especially dark-colored versions.
- Can contribute to increased attic temperatures during sunny weather.
Environmental Impact
Asphalt Shingles
- Made from petroleum-based materials.
- Contribute around 12 million tons of waste to U.S. landfills annually.
- Limited recyclability and shorter lifespan = more waste over time.
Metal Roofing
- Contains 25–95% recycled material.
- 100% recyclable at the end of its life.
- Fewer replacements = less landfill waste.
Environmentally conscious homeowners will appreciate the sustainability and low carbon footprint of metal roofs, especially in a region like Seattle where green building is valued.
Aesthetics and Home Design
Asphalt Shingles
- Wide range of colors, textures, and styles.
- Blend well with traditional Northwest architecture.
- Easy to match if you’re replacing part of your roof or following HOA guidelines.
Metal Roofing
- Offers a sleek, high-end aesthetic.
- Available in finishes that mimic slate, tile, or shake.
- Pairs well with:
- Modern farmhouses
- Contemporary homes
- Cabin-style properties
Metal roofs are a design-forward option, perfect for homeowners looking to boost curb appeal and stand out in a crowded real estate market.
Sound and Comfort
A common myth is that metal roofs are noisy during rainstorms—a concern in Seattle’s rainy climate.
The truth: Modern metal roofs are installed with solid decking and insulation, making them just as quiet as asphalt shingles. Some even perform better acoustically when paired with underlayment materials designed for sound dampening.
Maintenance and Repairs
Asphalt Shingles
- Require routine inspections for:
- Missing or cracked shingles
- Moss/algae buildup
- Moisture intrusion
- Repairs are generally affordable, but roofs often need full replacement around the 20–25-year mark.
Metal Roofing
- Virtually maintenance-free.
- Occasional inspection for fastener tightening or sealant issues.
- Less prone to damage = lower long-term maintenance costs.
For Seattle homeowners, where wet conditions accelerate shingle wear, a low-maintenance option like metal can be a huge relief.
Warranties and Return on Investment (ROI)
Warranties
- Asphalt Shingles: 20–30 years, often prorated after 10–15 years.
- Metal Roofing: 40–50+ years, many offer non-prorated, transferable warranties.
Return on Investment
- Asphalt: 60–65%
- Metal: 85–95%
Metal roofing is considered a premium upgrade, which can attract buyers and command a higher sale price—especially in Seattle, where sustainability and long-term value are important to homebuyers.
Local Considerations for Seattle-Area Homeowners
When choosing a roof in the Pacific Northwest, it’s important to factor in:
- Moss and algae resistance: Metal roofs are naturally resistant, while asphalt requires routine treatments.
- Rain management: Both systems work well when paired with proper gutters, but metal roofs shed water more efficiently.
- Energy codes: Washington State has some of the most progressive energy codes. Metal roofs often help meet energy-efficiency goals more easily.
- HOA or neighborhood aesthetic requirements: In historic districts or uniform neighborhoods, asphalt shingles may blend in better—but metal options can mimic traditional looks if needed.
Metal or Asphalt Roof – Which One Should You Choose?
Both asphalt shingles and metal roofing offer solid performance. The right choice depends on your budget, aesthetic preferences, and plans for homeownership. Ask yourself:
- How long do you plan to stay in your home?
- Short-term: Asphalt may be the budget-friendly pick.
- Long-term: Metal offers better value over time.
- Do you live in a harsh climate?
- Metal handles high winds, snow, and hail far better.
- Are you energy-conscious or eco-minded?
- Metal roofs reflect more heat and produce less landfill waste.
- Do you want a roof that adds resale value?
- Metal has a higher ROI and modern appeal.
