Metal roofing is growing fast in California — driven by wildfire risk in VHFHSZ communities, the appeal of Class A fire performance, solar compatibility, and long lifespan. Post-2017 Wine Country fires, 2018 Camp Fire, and 2025 LA fires have all accelerated metal roofing adoption in rebuilds.
Metal roofing costs in California:
- Standing seam steel: $22,000–$48,000 for a typical CA home
- Standing seam aluminum (coastal salt air areas): $26,000–$55,000+
- Metal shingles (Class A, aesthetically compatible): $20,000–$42,000
- Corrugated/exposed fastener metal: $16,000–$35,000
Why CA homeowners choose metal:
- Class A fire rating — required in VHFHSZ; metal is inherently Class A with no additional treatment needed
- Wildfire ember resistance — standing seam metal has no gaps for ember intrusion, a primary cause of home ignition
- 50–70+ year lifespan — vs. 20–25 years for composition shingle in CA's UV-intense climate
- Solar compatible — standing seam allows clamp-on solar mounting without roof penetrations; ideal for solar-ready roofing
- Title 24 cool roof compliant — light-colored metal panels have very high solar reflectance values
- Insurance benefits — some CA insurers offer discounts for Class A materials in VHFHSZ
