Two materials own the Sonoma County re-roof market: architectural asphalt shingle and standing-seam metal. Tile, wood shake, and composite each have a niche, but the real choice for most homeowners is between those two.
Here's how they actually compare on the seven things that matter.
| Factor | Architectural Shingle | Standing-Seam Metal |
|---|---|---|
| Installed cost (2,000 sqft) | $14k–$22k | $32k–$48k |
| Realistic lifespan | 25–30 yrs | 50+ yrs |
| Fire rating (with proper assembly) | Class A | Class A |
| Wildfire ember resistance | Good | Excellent |
| Noise during rain | Quiet | Audible (mitigated by deck + underlayment) |
| Resale value bump | Neutral / mild positive | Strong positive in fire zones |
| Maintenance | Replace lifted/missing shingles | Re-seal penetrations every 10–15 yrs |
Cost: The Honest Math
Metal costs roughly 1.8× to 2.5× more upfront. Per year of expected life, though, the numbers tighten — a $40,000 metal roof at 50 years is $800/yr; an $18,000 shingle roof at 28 years is $643/yr. Close, but shingle still wins on pure cost-per-year.
Where metal pulls ahead is in the second roof you don't have to buy. If you're staying in the home long term, especially with rising tear-off costs, metal can be the better total value.
Wildfire: The Sonoma County Differentiator
After Tubbs (2017), Kincade (2019), and Glass (2020), this stopped being a theoretical conversation. Both materials can achieve a Class A fire rating when installed in a proper assembly, but they fail differently.
Metal panels don't ignite. Embers landing on standing-seam steel cool and slide off. Asphalt shingles with a fiberglass mat and gypsum-treated underlayment also resist ignition, but the granular surface can hold burning debris longer.
If your home is in a Cal Fire High or Very High Fire Hazard Severity Zone, metal is worth the premium. If you're in central Santa Rosa or downtown Petaluma, shingle is more than sufficient.
Noise: The Most Misunderstood Factor
The barn-roof rain-on-tin sound is real — for a barn. On a house with full plywood decking, synthetic underlayment, an attic, and insulation, a properly installed standing-seam roof is barely louder than shingle during rain. Most homeowners don't notice after the first storm.
Aesthetics: What Fits a Sonoma County Home
Metal looks right on contemporary, farmhouse, and ranch architecture — exactly what dominates west Healdsburg, Sebastopol, and rural Petaluma. On Victorian or traditional craftsman homes (a lot of central Santa Rosa, downtown Healdsburg), architectural shingle in a charcoal or weathered-wood blend almost always reads better.
Color matters more than you think
Cool-roof colors (light gray, sand, weathered copper) reduce attic temperatures by 10–20°F in our August heat. That's real money on AC bills, and California's Title 24 increasingly requires it on re-roofs in certain climate zones.
Resale: What Realtors Actually Tell Us
In fire-zone listings, a standing-seam metal roof is now a marketing bullet. Buyers ask about it before they ask about the kitchen. In urban Santa Rosa or Cotati, a new architectural shingle roof is what buyers expect — anything more is a nice-to-have, not a deal-maker.
The Short Answer
- Staying 15+ years and in a fire zone: metal.
- Staying 5–10 years, traditional architecture: architectural shingle.
- Tightest budget: 30-year architectural shingle from a major manufacturer.
- Trying to make a statement on a modern home: standing-seam metal in a cool color.
Either way, the install matters more than the material. We've torn off 8-year-old metal that was leaking because flashings were wrong, and we've torn off 35-year-old shingles that still had life because the original installer ventilated the attic correctly.

Frequently Asked Questions
Will metal roofing make my home hotter?
Opposite, actually. Light- to mid-tone metal roofs reflect 30–60% of solar heat versus dark shingles, dropping attic temperatures noticeably. We can show you Title 24 compliant cool-roof colors at the estimate.
Does metal void my homeowners insurance discount?
Most California insurers — including the FAIR Plan — offer the same or better discounts for Class A metal as for Class A shingle. A few even offer wildfire mitigation credits specifically for standing-seam metal in fire zones.
Can metal go over existing shingles?
We don't recommend it. The hidden moisture and unevenness shorten panel life and complicate warranties. Tear off, inspect the deck, and start clean.
