Material Comparison
Asphalt vs. Metal Roofs in Oregon — A Head-to-Head.
Quick Answer
Standing-seam metal performs better in Oregon's wet climate — longer lifespan, better moss resistance, superior water shedding. A shingle-based system (architectural asphalt or composite) remains the better value if you want lower up-front cost and a 20–30 year roof. For flat or low-slope sections, neither applies — see our materials guide for plastic-based membranes (TPO, PVC, EPDM).
Quick summary table
| Factor | Shingle-Based (Asphalt) | Standing-Seam Metal |
|---|---|---|
| Lifespan in PNW | 20–30 years | 40+ years |
| Moss / algae resistance | Fair (good with AR granules) | Excellent |
| Water shedding | Good | Excellent |
| Maintenance | Low–moderate | Very low |
| Rain noise | Quiet | Quiet (properly installed) |
| Resale impact | Neutral | Often a positive |
| Recyclability at end of life | Partial | Fully recyclable |
| Installer availability in Eugene/Springfield | Wide | More limited (we install both) |
Cost
A shingle-based roof wins on up-front cost — typically 50–65% less than standing-seam metal on a comparable home. But cost-per-year tells a different story: a 30-year shingle-based roof and a 60-year metal roof end up at roughly the same annual cost — and the metal option avoids the one-time cost and disruption of a second installation in your lifetime.
Lifespan in PNW conditions
Architectural asphalt with algae-resistant granules, proper ventilation, and proper maintenance can last 20–30 years in the Willamette Valley. Standing-seam metal regularly gets 40+ years. Both depend on installation quality — a poorly flashed metal roof can fail in 10 years, and a well-installed asphalt roof can hit the high end of its range.
Noise & aesthetics
Noise: a common worry about metal is rain noise. On a properly installed residential standing-seam roof (with solid decking and underlayment), the difference vs. shingles is negligible. The "tin roof in the rain" sound comes from open-frame barn construction, not modern residential installs.
Looks: highly personal. Shingle-based systems are the visual default for most Eugene/Springfield homes. Standing-seam metal pairs especially well with modern, farmhouse, and rural-residential homes. Both come in a wide range of colors and profiles.
Resale value
Recent industry data (drawing on Remodeling Magazine's annual Cost vs. Value Report) suggests metal roofs recover 60–95% of their cost at resale, depending on the home and market. Shingle-based roofs are neutral at resale — they're expected, not a selling feature, unless they're new. In the Eugene/Springfield market, a recent metal roof is often a real selling point on modern, farmhouse, and higher-end homes.
Which is right for you?
Pick a shingle-based system if…
- You want the most cost-effective new roof — architectural asphalt is the everyday choice; composite is the premium variant.
- Your home style is traditional, ranch, Craftsman, or mid-century.
- You're planning to sell within the next 10–15 years.
- You're comfortable with re-roofing in 20–30 years.
Pick standing-seam metal if…
- You're planning to stay in the home long-term (or pass it down).
- Your home is modern, farmhouse, or rural-residential.
- You want the lowest-maintenance roof available.
- You value resale strength and recyclability.
FAQs
Can a metal roof be installed over my existing asphalt?
In some cases yes — but we generally recommend a full tear-off. Going over existing shingles complicates flashing, traps moisture, and shortens the new roof's effective lifespan.
Do metal roofs attract lightning?
No — this is a myth. Metal roofs don't increase lightning risk, and if a strike does happen, metal is less flammable than asphalt or wood.
How long does metal roof installation take vs. asphalt?
A standing-seam metal install typically takes 2–5 days on a single-family home, compared to 1–3 days for a shingle-based roof. The difference is in the precision of panel layout, custom flashing, and seam crimping.
Do you install both?
Yes. Storm Roofing installs shingle-based systems (architectural asphalt and composite) and standing-seam metal across Eugene, Springfield, and the surrounding Willamette Valley. Request a free estimate and we'll walk through which is right for your home.
