Metal roofing in San Diego. Built to last 50 years.
Metal roofs are gaining share in San Diego for three reasons: Class A fire rating (important in wildfire zones), 50-year lifespan, and modern profiles that don't look like the old corrugated barn roofs. Standing seam is the premium option; stone-coated steel mimics tile or shingle look.
What's included in this service?
- Standing seam metal (the premium option, clean modern look)
- Stone-coated steel (tile-profile and shingle-profile, lighter than real tile)
- Corrugated metal (budget option, utilitarian look)
- Salt-rated aluminum and stainless finishes for coastal homes within 2 miles of ocean
- Class A fire-rated assemblies for wildfire zones
- Concealed vs. exposed fastener systems
- Proper thermal expansion detailing (critical for long-term watertightness)
- Snow retention hardware for mountain homes
When do you need this service?
- Home is in a wildfire zone requiring Class A fire-rated roofing
- Existing tile is too heavy and structure cannot support a lift-and-relay
- Modern or mid-century architecture where standing seam matches the look
- Long-term-ownership homes where 50-year lifespan ROI works
- Barn, shop, or detached structure where metal is the right fit
- Coastal home where salt corrosion has destroyed previous shingle roofs
Metal roofing in San Diego: where it pays off and where it doesn't
Standing seam vs. stone-coated steel: two different products, same category
Most San Diego homeowners assume 'metal roof' means one thing. It actually splits into two very different categories. Standing seam is interlocking vertical panels with raised seams running roof-deck to ridge, no exposed fasteners, modern clean look, $22,000 to $38,000 installed for a typical 2,000 sq ft home. It's the premium choice for modern, mid-century, or contemporary architecture. Stone-coated steel is steel panels stamped to mimic tile, shake, or shingle profiles, then coated with stone granules for color and texture. It runs $18,000 to $28,000, weighs about a third of real tile, and lets homeowners get a tile look on a structure that can't support tile weight. Both deliver 40 to 50 year lifespan and Class A fire rating. The choice usually comes down to architecture and budget.

Coastal salt resistance: rank the metals from best to worst
If your home is within 2 miles of the Pacific (Coronado, Imperial Beach, Ocean Beach, Point Loma, La Jolla, Pacific Beach, Mission Beach, Del Mar, Solana Beach, Cardiff, Encinitas, Carlsbad, Oceanside), metal selection matters more than for any other vertical. Standard galvanized steel (G-90 zinc coating) starts visible corrosion within 8 to 12 years of coastal salt exposure. Galvalume (zinc-aluminum coating) lasts 20 to 30 years coastal. Aluminum is naturally corrosion-resistant, never rusts, 40 to 50+ year coastal life, the practical premium choice for most coastal homes. Stainless steel is the ultimate choice (50+ years coastal, no degradation) but the cost premium is meaningful. Copper for accent metals (flashing, gutters) is also salt-bulletproof. See will salt damage a metal roof in San Diego for the full ranking. Any roofer quoting plain galvanized for a coastal install is setting you up for a corroded roof in a decade.
Title 24 cool-roof requirements and SDG&E rebates
California's Title 24 building code requires cool-roof performance on most residential roof replacements in San Diego County (Climate Zones 7 and 10). For low-slope roofs, the requirement is 3-year aged solar reflectance of at least 0.55. For steep-slope (most homes), the requirement is 0.20 aged reflectance for prescriptive compliance, with alternative compliance paths for darker roofs. Metal roofs in lighter colors usually hit cool-roof spec out of the box; metal in dark colors needs specific cool-roof pigments to comply. A good roofer should confirm Title 24 compliance in writing on the quote and pull the Energy Title 24 form (CF-1R) for permit submittal. SDG&E also runs periodic cool-roof rebate programs, usually $0.20 to $0.50 per square foot for qualifying installs. See cool-roof rebates from SDG&E and cool-roof Title 24 in San Diego for current program details.
The cost premium math: when metal actually pays back
Metal costs 40% to 80% more than architectural shingle at install. The payback math turns on three variables: how long you own the home (metal's 40 to 50 year life beats shingle's 20 to 25 year life, a single shingle replacement during your ownership erases the upfront premium), insurance discounts in California fire zones (some carriers offer 5% to 15% premium reductions for Class A metal, meaningful in WUI zones like Ramona, Alpine, Julian, Valley Center, Jamul), and coastal salt exposure (if your shingle roof failed in 12 years from salt damage, metal's aluminum or stainless option is the only thing that breaks the cycle). For homeowners planning to stay 15+ years, in a fire zone, or within 2 miles of the coast, metal is usually the cheaper long-term answer. For a flip or a 5-year-ownership plan, shingle wins on upfront cost. See are metal roofs cheaper than shingles in San Diego for the full lifetime cost comparison.
What to look for in a metal roofing installer
Metal roofing is less forgiving than shingle. Thermal expansion (a 40-foot panel can grow 3/8 inch on a hot day vs. cold morning), concealed vs. exposed fastener detailing, panel clip selection, and seam crimping all have to be right or the roof leaks. Many shingle roofers will quote a metal job; far fewer have installed enough to do it well. When connecting with a roofer for a metal install, ask: how many standing seam (or stone-coated) installs in the past 12 months? What's the manufacturer's installer certification (Englert, McElroy, Decra, ATAS, Boral)? What clip and fastener system, and what's the thermal expansion allowance? How are end-laps and side-laps detailed at hips and valleys? Every metal roofer in our San Diego network is vetted for manufacturer certification and recent install volume.
What do homeowners ask about Metal Roofing?
Does metal roofing cost more than shingle?
Yes, typically 40–80% more than architectural shingle. But the lifespan is 2x, the fire rating is better, and insurance discounts in fire zones can be meaningful. Lifetime cost often favors metal for owners staying in the home 20+ years.
Is metal roofing loud when it rains?
No, not in a residential install. Metal roofing installs over decking and underlayment, the metal panel itself is only the waterproof layer, not the acoustic surface. Rain on a properly installed metal roof sounds about like rain on a shingle roof from inside the house. The 'metal roof is loud' myth comes from open-frame barn installs.
Will a metal roof attract lightning?
No. Metal roofs are not more likely to be struck by lightning than any other roof. If struck, metal is safer, it disperses the charge and is non-combustible. Shingle and wood-shake roofs are more likely to ignite from a lightning strike than metal is to attract one.
What about coastal salt corrosion?
Standard galvanized steel metal roofs corrode within 10 years near the coast. For homes within 2 miles of the ocean, we specify aluminum (naturally corrosion-resistant) or stainless steel. The upcharge is meaningful but the lifespan recovers.
Can I put solar on a metal roof?
Yes, and metal + solar is a great combination. Standing seam metal roofs take solar mounts via non-penetrating clamps, no holes, no warranty voids. The roof and solar can be matched for the same 25–50 year lifespan.

Our 1990s Spanish tile roof was leaking in three spots. Called Top Pro and they had a tile specialist out the next morning. Instead of pushing a full tear-off, the roofer they matched us with did a lift-and-relay with new underlayment and salvaged 90% of the original tiles. Crew was meticulous. Passed inspection on the first visit.
Was about to pull the trigger on a full tear-off and reroof but wanted one more opinion. Top Pro connected me with a local roofer the same day. He was the only one who actually pulled up into the attic to check for rot before quoting. Found damage the others missed. Fair price. Crew was on time every day. Saved me from picking the wrong bid.
Live three blocks from the ocean. Salt killed our old shingle roof in 12 years. Top Pro matched us with a roofer who actually does coastal metal installs. He put down stone-coated steel with stainless fasteners and coordinated the HOA design review paperwork himself. Clean lines, clean job site. No shopping around required.
