Metal Roof vs Asphalt Shingles: Which Is Better for Your Home?
Introduction
The comparison between a metal roof vs asphalt shingles has changed in recent years as both materials have improved. Asphalt shingles have become more durable and weather-resistant, while metal roofing has become more accessible and slightly more affordable for residential homes.
However, when evaluating cost, performance, and long-term value, asphalt shingles remain the best roofing option for the majority of homeowners.
This guide provides an updated comparison of metal roofing and asphalt shingles, based on the decades of collective experience of the S&S Exteriors team, to help homeowners make the right decision based on climate, budget, and long-term ROI.
Metal Roof vs Asphalt Shingles: Complete Comparison
Cost Differences
One of the biggest differences in the metal roof vs asphalt shingles debate is cost. In general:
Metal roofs cost 2–3x more than asphalt shingle roofs
Asphalt shingles remain the most cost-effective roofing system for residential homes
However, roofing decisions should be based on how many years of protection a roof offers, not only upfront price. A properly installed architectural asphalt shingle roof with quality underlayment, ventilation, and certified installation can last 50+ years, and in many cases performs similarly to metal roofing in moderate climates.
For the majority of homeowners, asphalt shingles provide:
Lower upfront investment
Strong durability in moderate climates
Easier and cheaper repairs
Better overall return on investment
Metal roofing only becomes more competitive in specific high-stress environments.
Ideal Climates
Asphalt shingles perform best in:
Moderate climates
Low to moderate wind regions (GAF offers modern, high wind resistance shingles)
Areas without extreme snow loads or heat (Modern ventilation and ice barrier will protect an asphalt shingle roof from these issues)
Metal roofing performs best in:
High-wind zones
Heavy snow and ice regions
Severe storm environments
In most of the Portland Metro area, including Sandy and Gresham, Oregon, asphalt shingles are the superior choice due to the mild, wet, and balanced climate conditions.
Maintenance
Both roofing systems require relatively low maintenance when properly installed. Modern architectural asphalt shingles now include:
Algae-resistant granules
Zinc or copper-infused protection
10–15+ years of resistance to organic growth
Metal roofs are also low maintenance but may require:
Periodic inspection after hail or debris impact
Protective coating maintenance in some cases
Rust prevention attention in damaged areas
Overall Asphalt shingles are better for maintenance because they are simpler and more predictable long-term.
Aesthetic Options
Metal roofs offer a clean, modern, and industrial aesthetic with:
Standing seam panels
Corrugated profiles
Limited but sleek color options
However, asphalt shingles provide far greater design versatility, including:
Wide color selection
Dimensional textures
Shadow lines and depth variation
Premium designer shingles like GAF Grand Sequoia
For most homes, asphalt shingles provide a more natural, traditional, and visually flexible appearance.
Durability & Warranties
While metal roofing is often marketed as more durable, real-world performance tells a more nuanced story.
High-quality asphalt shingles from manufacturers like GAF offer:
50-year warranties
Wind resistance protection
Algae resistance coverage
System-based warranty protection (when installed by certified contractors)
Important note:
Only a small percentage of roofing contractors are manufacturer-certified, and installation quality has a major impact on roof lifespan. This is why it is important to hire a certified roofer, like S&S Exteriors, to install your asphalt roof. Otherwise, the vast advantages of an asphalt roof may disappear.
In moderate climates, a properly installed asphalt shingle system can perform similarly to metal roofing over its service life.
Real-World Roofing Examples
In one case, a homeowner with a metal roof experienced corrosion and storm-related damage that required emergency repair. After evaluation, they replaced the system with a high-quality asphalt shingle roof installed by S&S Exteriors, which provided a more cost-effective and practical long-term solution for their home and climate.
In another case, a homeowner selected a metal roof primarily for aesthetic reasons and curb appeal. While asphalt shingles would have provided sufficient performance, they prioritized design preference over cost efficiency.
Conclusion: Asphalt Shingles Are the Best Roofing Choice for Most Homes
When comparing metal roof vs asphalt shingles, the data is clear:
Asphalt shingles are more affordable
Asphalt shingles provide better ROI in most climates
Asphalt shingles offer strong durability when properly installed
Asphalt shingles provide more design flexibility
Asphalt shingles are easier and cheaper to maintain and repair
Metal roofing can be a good option in specific extreme climates or for homeowners prioritizing a modern architectural aesthetic. However, for the vast majority of homes, especially in regions like Portland, OR, Sandy, and Gresham, asphalt shingles remain the most practical, cost-effective, and high-value roofing system.
