Metal Roof vs Shingles in Los Angeles
A metal roof vs shingles choice in Los Angeles, CA comes down to a higher price now against a longer life later. Metal usually costs more to install and lasts two to three times as long as asphalt shingles, per the cost comparisons that Bob Vila, EcoWatch and Angi publish. The figures below carry their sources, and the right choice also depends on how long the owner expects to stay.
Cost per square foot
Angi's Los Angeles page puts standing seam metal at about $7 to $30 a square foot. HomeAdvisor's 2024 page puts asphalt shingles at $4 to $12 installed. One metal supplier's worked example prices standing seam at $8 to $14 a square foot against $5 to $7 for asphalt, but a supplier has a reason to favor metal, so treat it as a rough guide only.
Lifespan
InterNACHI's figures give architectural shingles about 30 years and metal 40 to 80 [thisoldhouse.com, updated 2026-04-07]. A house that outlives its first shingle roof pays for two shingle roofs against one metal roof. An owner planning to sell within a few years may not recover the higher price.
Fire rating and cool roof rules
Both metal and Class A shingles can meet the Class A requirement in mapped Very High Fire Hazard Severity Zones, and a residential replacement over half the roof area in the City of Los Angeles needs a Cool Roof Rating Council rated product either way [LA County Public Works notes; LADBS bulletin IB P/GI 2020-003]. The product choice is about the listed assembly, not the metal-versus-shingle label.
Which fits which house
Shingle suits a modest budget and a simple roof. Metal suits a long stay, a modern design or a steep roof where repairs are hard. Tile suits Spanish and Mediterranean houses and is covered on its own page. A roofer measuring the roof can price all three in one visit.
