How much does a metal roof cost in San Diego?

In 2026, 24-gauge standing-seam metal runs $18–$26 per sq ft installed, aluminum for coastal homes $22–$30, and exposed-fastener steel panel $10–$15. A typical 2,200 sq ft San Diego home lands between $40,000 and $66,000 including tear-off and permit.

How long does a metal roof last in San Diego?

Standing-seam 24-gauge steel lasts 40–60 years inland, aluminum 50+ years on the coast, and copper or zinc up to 100 years. Exposed-fastener panels realistically last 15 years because the neoprene washers dry out and start leaking.

Is metal roofing good for coastal San Diego salt air?

Yes, if the alloy and coating are right. Within about a mile of the ocean specify aluminum or Galvalume AZ-55 with a full-strength Kynar 500 PVDF finish and 304/316 stainless fasteners. Standard galvanized steel and zinc-plated screws corrode within a few years.

Can I put a metal roof over my existing shingle roof?

Often yes. Metal weighs only 1–1.5 lbs per sq ft, so no framing reinforcement is needed. We still recommend a full tear-off so the decking can be inspected and high-temp synthetic underlayment installed correctly.

Does a metal roof qualify for California cool-roof credit?

Lighter Kynar 500 finishes meet the solar-reflectance and thermal-emittance values California's Title 24 cool-roof provisions look for. We document SRI values on every metal roofing proposal so compliance paperwork is handled.

Can solar panels be installed on a metal roof?

Yes — standing seam is the best solar substrate available. S-5! clamps attach directly to the panel ribs with zero roof penetrations, so there are no new holes and no leak risk from the racking.

Metal Roof San Diego: Cost, Types & 2026 Buyer Guide

A metal roof is the longest-lasting roof most San Diego homes will ever wear. Installed correctly, a 24-gauge standing-seam system outlives two or three asphalt shingle roofs, carries a Class-A fire rating for wildfire-exposed canyons, and reflects enough heat to cut attic temperatures by 20–30°F in an Inland Valley summer. Installed incorrectly — wrong alloy near the coast, exposed fasteners, no high-temp underlayment — it can fail in under a decade. This guide covers what actually matters when you buy a metal roof in San Diego County.

Metal roof types available in San Diego

Standing seam (concealed fastener): the premium residential choice. 1.5"–2" vertical ribs, no screws penetrating the panel face, 40–60 year service life. What we install on the majority of San Diego homes.
Exposed-fastener corrugated / R-panel: the budget option. Fine for barns, ADUs, and inland outbuildings; the neoprene washers dry out in 12–15 years and become the leak path.
Metal shingle and stone-coated steel: shake or tile profiles for HOA neighborhoods where a modern ribbed panel won't get approved.
Aluminum standing seam: the correct call within roughly a mile of saltwater — La Jolla, Pacific Beach, Del Mar, Coronado, Oceanside.
Copper and zinc: heirloom metal for estate homes, 100-year lifespan, natural patina.

2026 metal roof cost in San Diego

Exposed-fastener steel panel: $10–$15 per sq ft installed.
24-gauge Galvalume standing seam: $18–$26 per sq ft installed.
Aluminum standing seam (coastal): $22–$30 per sq ft.
Stone-coated steel tile/shake profile: $16–$24 per sq ft.
Copper or zinc: $30–$55 per sq ft.
Typical 2,200 sq ft San Diego home: $40,000–$66,000 for a warrantied standing-seam system, including tear-off, decking repairs, and permit.

Structural cost is usually lower than tile: metal weighs 1–1.5 lbs per sq ft versus 9–11 for concrete tile, so no framing reinforcement is required when converting from shingle.

Why metal makes sense in San Diego specifically

Wildfire. Homes in Poway, Ramona, Alpine, Rancho Santa Fe, and Escondido's eastern canyons sit in CAL FIRE hazard zones. A metal panel over a fire-rated underlayment is a Class-A assembly with no combustible surface for embers to ignite.

Title 24 and cool-roof credit. Kynar 500 finishes in lighter colors hit the solar-reflectance and thermal-emittance values California's cool-roof provisions look for, and SDG&E-area energy programs periodically offer reflective-roof incentives. We document SRI values on every metal proposal so the compliance paperwork is done for you.

Salt air. Coastal San Diego eats cheap metal. Specify Galvalume AZ-55 or aluminum with a full-strength 70% PVDF (Kynar 500 / Hylar 5000) finish and 304/316 stainless fasteners — never zinc-plated screws, never "Kynar-blend" SMP paint.

How long does a metal roof last here?

Realistic San Diego service life: 15 years for exposed-fastener steel, 40–60 years for 24-gauge standing seam, 50+ for aluminum on the coast, 100 years for copper. The limiting factor is almost never the metal — it's the underlayment and flashing. Insist on high-temp synthetic underlayment (Sharkskin Ultra SW or equivalent) and soldered or stainless flashing at valleys, walls, and penetrations.

Metal roofing myths San Diego homeowners still hear

"They're loud in the rain." Over solid decking and underlayment, a standing-seam roof is quieter than tile.
"They attract lightning." Metal is not more likely to be struck, and it's non-combustible if it is.
"They dent." 24-gauge steel shrugs off San Diego hail; thin 29-gauge panels are what dent.
"They void solar." The opposite — S-5! clamps mount to standing-seam ribs with zero roof penetrations, the cleanest solar attachment there is.

Recent standing-seam metal roofs we installed in San Diego

Every photo below is our own crew's work — panels, skylight curbs, seam clamps, and fascia metal fabricated and installed by California First Roofing.

Finished 24-gauge standing seam field — straight, evenly spaced seams from eave to ridge with concealed clips and no exposed fasteners.

Skylight set on a raised curb with custom-bent pan and head flashing tucked under the panels — the detail that stops leaks at penetrations.

Three skylights sequenced down the slope, each with its own diverter so water is carried around the curb instead of dammed above it.

Framed and cricketed skylight opening prepped before the glass drops in — new lumber, waterproofed curb, and panel-height flashing.

Seam-level close-up: machine-formed ribs with hemmed edges and factory Kynar/PVDF finish rated for 40 years of color retention.

Curb wrapped in color-matched metal before the unit is set, so the transition sheds water even mid-installation.

Standing seam carried from roof onto the wall as cladding — a modern-architecture detail we fabricate and install in-house.

Solar mounted with S-5!-style seam clamps: zero roof penetrations, so the 50-year metal warranty stays intact.

Curved (radius-formed) standing seam over a barrel roof on an ocean-view home — panels roll-formed on site to follow the arc, paired with a white single-ply flat section for the low-slope wing.
