Metal Roofing in Los AngelesStanding Seam & Stone-Coated Steel
Metal costs more upfront than shingles. In Los Angeles it can also settle a fire-zone, roof-weight or permit question that tile and shingle can't, so the answer depends on your address as much as your budget.

The Two Metal Roofs LA Homes Get
Standing Seam
Vertical metal panels joined by raised, interlocking seams above the roof deck, so the fasteners are hidden. It comes in steel, aluminum and copper, and steel is the usual choice on LA houses. It suits simple roof planes and the flat-to-low-pitch rooflines common on mid-century and hillside modern homes, and it's also used on low-slope commercial buildings; see commercial roofing in Los Angeles for that side.
Stone-Coated Steel
Steel panels with a stone-chip surface, formed and colored to read as tile, shake or slate from the street. It's the metal option for a house where a tile profile matters, and it puts steel's fire rating on the roof without tile's weight on the framing. Check the product's data sheet for its weight and its Class A listing; both vary by manufacturer.
For how metal stacks up against tile, shingle and flat roofing across the region, see the guide to the best roofing materials for Southern California.
Metal in LA's Fire Zones: What "Class A" Covers
A roof in a Very High Fire Hazard Severity Zone has to carry a Class A covering; that's a condition printed on the LADBS Express Permit bulletin, and the underlying rules are in CBC Chapter 7A and CRC R337. The zone lines are moving. CAL FIRE issued recommended maps for the Los Angeles area on March 24, 2025, and the LAFD said it expected more parcels to be affected, with the City adopting the maps by ordinance after public hearings. A house that sat outside the zone on the old map may not on the new one, so check the address before you rule Class A out.
Metal panels are non-combustible and commonly Class A rated, but the rating applies to the tested assembly, not the sheet of steel. The listing names the panel, the underlayment, the deck and the installation method. Swap the underlayment or change the panel profile and you may be outside what was tested. The permits guide, how roofing permits work in Los Angeles, covers what the building department asks to see.
- The listing. Ask for the panel's Class A listing and confirm it covers your deck type.
- The underlayment, by name. If the listing specifies one, the quote should say so, not "underlayment".
- The permit path. In the City of LA it's usually an Express Permit; in Pasadena, Glendale, Burbank and other cities it's the local building department.

Weight and the LADBS Express Permit
The City of LA's Express Permit lets a reroof skip plan check when it's a Class A or B covering under 6 lb/sq ft over solid sheathing. Metal panels sit far under that line. New clay or concrete tile doesn't, and that gap decides which permit path a tile-to-metal swap takes. The same weight difference shows up on the roof: a 100 sq ft square of 24-gauge steel panel weighs roughly 100 to 116 lb, against roughly 900 to 1,200 lb for concrete tile.
Two limits. The bulletin covers the City of Los Angeles only, and it assumes solid sheathing under the panels. Stone-coated steel isn't in the table, so read its data sheet against the 6 lb line. Inspection is still required after tear-off.
| Covering | Approx. weight, lb/sq ft |
|---|---|
| 26-gauge steel panel | 0.75–0.91 |
| 24-gauge steel panel | 1.00–1.16 |
| Clay tile | 6–10 |
| Concrete tile | 9–12 |
| Express Permit limit | under 6 |

Near the Ocean: Aluminum, Galvalume and the 1,500-Foot Line
Salt air and marine moisture are generally understood to age metal flashing and fasteners faster near the coast, and metal panels are where manufacturers write that risk into the warranty. Steel warranties commonly exclude installations within roughly 1,500 feet of the shoreline, and Galvalume, the standard coated steel, is no exception. Aluminum is the material metal suppliers recommend for heavy salt exposure, and coastal-engineered steel products exist for owners who want steel anyway.
In LA that line matters for parts of Venice, Playa del Rey, Marina del Rey, Santa Monica, the beach cities and San Pedro. Inland neighborhoods such as the Valley, Pasadena and Glendale are well outside it. If the house is close, read the warranty's coastal clause before you pick the metal. Supplier guidance also calls for hot-dipped galvanized or stainless fasteners within several thousand feet of the coast, and prompt touch-up of scratches and cut edges.
Aluminum's installed range in the national figures below runs $12 to $18 per sq ft against $12 to $16 for steel, a modest gap on a house where the steel warranty may not apply.

Title 24: Whether the Color Has to Be Cool-Rated
The cool-roof rule for a steep-slope single-family reroof depends on the climate zone, and LA straddles three of them. Coastal LA is Climate Zone 6, where a steep-slope single-family reroof has no cool-roof requirement. South and East LA, Inglewood, Culver City and inland South Bay are Zone 8; the San Fernando Valley is Zone 9; mountain areas run into Zone 14. In those zones the roof covering has to meet an aged solar reflectance of 0.20, thermal emittance of 0.75 and SRI of 16, unless an exception applies (extra ceiling insulation, a radiant barrier and a few others).
Those numbers are low next to the 0.63 reflectance a low-slope roof needs, so on a steep roof the job is mostly picking a color whose CRRC-listed aged values clear the bar, not buying a special product. Confirm the parcel's zone with the CEC lookup, and see the Title 24 cool roof guide and the cool roofs page for rebates and coatings.
| Area | Zone | Steep-slope single-family reroof |
|---|---|---|
| Coastal LA | 6 | No cool-roof requirement |
| South/East LA, Inglewood, Culver City | 8 | 0.20 / 0.75 / 16 |
| San Fernando Valley | 9 | 0.20 / 0.75 / 16 |

Which LA Houses Suit Metal
| House type | Fit | Why |
|---|---|---|
| Mid-century modern and hillside modern (Silver Lake, Hollywood Hills) | Good | Simple planes and shallow pitches suit standing seam. On steep lots with truck-free access, panels are far lighter to carry up than tile: about 100 lb per square against roughly 900 to 1,200 lb. |
| Post-war ranch and tract houses | Case by case | Straightforward roofs, so the real question is price against architectural shingle and whether you'll stay. |
| Spanish and Mediterranean tile houses, not in an HPOZ | Stone-coated steel | A tile profile keeps the street look at metal's weight. |
| Houses in a Historic Preservation Overlay Zone (HPOZ) | Needs review | Changing the roofing material is a design-review question, not a formality. |
Silver Lake is a useful example: it has a large concentration of architect-designed mid-century homes and, unlike Angelino Heights or Miracle Mile, no City HPOZ, so there's no overlay roof review there. Inside an HPOZ it's different. The City says most exterior changes need written approval from Planning, and the Miracle Mile plan treats in-kind replacement (asphalt shingle for asphalt shingle, clay tile for clay tile) as routine work while asking that any other roofing be substantially similar in appearance, scale, texture and color. A standing seam roof on a Spanish Revival house is unlikely to read as similar. Each HPOZ has its own plan, so ask the HPOZ planner before you price anything.

What Metal Costs, Next to LA Shingle and Tile
No LA-specific metal range is published, so the standing seam figures are national. Prices are per square foot of roof area, not floor area: a 1,600 sq ft floor plan at a 6/12 pitch is about 1,800 sq ft of roof. Labor runs 40 to 60% of a standing seam job, and steel is the economical metal; copper costs several times as much.
| Roof | Per sq ft installed | 2,000 sq ft of roof |
|---|---|---|
| Standing seam, residential (national range) | $10–$20 | $20,000–$40,000 |
| Asphalt shingle (LA) | $6.50–$15.20 | $13,000–$30,400 |
| Clay or concrete tile (LA) | $12–$25 | $24,000–$50,000 |

By metal, the national figures are about $12 to $16 for steel, $12 to $18 for aluminum and $20 to $40 for copper. The bottom of the metal range overlaps the middle of the shingle range, and the whole range overlaps the tile range. That makes metal-versus-tile the closer contest, and metal-versus-shingle the wider gap, widest against basic 3-tab.
Deck condition, skylights, vents and chimneys, pitch and access all move the price. Lifespan changes the per-year math; the arithmetic is in how long does a roof last in LA.
When Metal Is Worth It in LA, and When It Isn't
Metal is worth the money in three LA situations: a house in a fire zone that you'll keep well past a shingle roof's 20 to 45 years; a tile roof whose underlayment is done and where re-laying heavy tile costs more than a lighter metal covering; and a modern or hillside house where standing seam suits the design. Outside those, shingle usually wins on price.
- Flat-lot house outside any fire zone. An architectural shingle roof does the job for meaningfully less, and the Valley and much of the Westside fall here.
- Short ownership. Metal's advantage is decades of avoided replacements. If you'll sell in a few years, you won't collect it.
- Inside an HPOZ, on a tile or Spanish Revival house. Plan on design review, and don't assume metal gets approved. Ask the HPOZ planner first.
- Within 1,500 feet of the ocean on steel. The warranty may not cover you. Price aluminum or a coastal-rated steel instead, and factor in the premium.
- Complicated roofs. Valleys, dormers and penetrations add labor, a bigger share of a metal job than of a shingle job.
- Fire zone on a tight budget. A Class A-listed shingle or tile assembly can meet the same requirement for less, if weight isn't a constraint.

Metal Roof Repair & Maintenance
Most metal roof problems trace back to a handful of spots: fasteners backing out on exposed-fastener panels, sealant failing at penetrations and flashing, and seams that were rolled or crimped incorrectly during the original install. Repairs on standing seam should be done by a crew experienced with that seam profile, since a poor repair can undo the watertight advantage the system is supposed to provide. To have a leak diagnosed on any roof type, including metal, see roof repair in Los Angeles.
Metal Roofing FAQs
Are metal roofs allowed in California, including in fire zones?
Yes. Nothing in California bars metal, and in a fire zone it is one of the ways to meet the Class A requirement. The catch is paperwork: the Class A listing belongs to a tested assembly, so the quote should name the panel, the underlayment and the deck, with a listing number you can look up. Outside the City of Los Angeles, the local city or LA County Public Works issues the permit, not LADBS.
What is a standing seam roof, and is it better than other metal?
Standing seam panels lock together along raised seams, so the fasteners are hidden. Exposed-fastener panels are screwed through the face, and those screws and their washers are the usual thing to back out or leak. Standing seam costs more for that reason. Stone-coated steel is a different product: formed steel panels with a stone-chip surface that mimic tile or shake, which is the option to look at on a house where the roof line has to keep a tile profile.
How long does a metal roof last in LA?
Industry consensus puts steel at 40 to 60 years and aluminum at 50 to 80, against 20 to 45 for asphalt shingles; those are consensus figures, not code. The panel is rarely what ends the roof's life. Sealant at penetrations, flashing and seam details fail first, and on a house within about 1,500 feet of the ocean the finish warranty may not apply at all.
What's the biggest problem with a metal roof?
Workmanship you can't see from the ground. A watertight standing seam roof depends on seam profile, expansion allowance and how each penetration is flashed, and a poor repair can undo it. That is why a metal quote should be compared line by line, not on price alone, and why a leak on a metal roof should go to a crew that works with that seam profile.
