Metal vs Asphalt Shingles: Which Is Right for Your LA Home?
Metal roofs last 40-70 years while asphalt lasts 15-30. Compare costs, energy savings, and performance for Los Angeles homes.
Los Angeles homeowners replacing a roof usually narrow it down to two choices: metal or asphalt shingles. Both work well in Southern California, but they perform differently in LA’s heat, handle Santa Ana winds differently, and come at very different price points.
Here’s how they compare on the things that actually matter for your home.
What Are Asphalt Shingles?
Asphalt shingles are the most common roofing material in the United States. They consist of a fiberglass mat coated in asphalt and covered with ceramic granules. The granules provide color and UV protection.
Types of Asphalt Shingles
- 3-tab shingles are flat, single-layer shingles. They cost less and last 15-20 years.
- Architectural (dimensional) shingles have a layered, textured look. They last 25-30 years and handle wind better.
- Impact-resistant shingles carry a Class 4 rating and resist hail and debris damage.
Most LA homes built after 1990 have architectural shingles. Older homes from the 1950s-1970s often still have 3-tab, especially in the San Fernando Valley.
Advantages of Asphalt Shingles
Lower upfront cost is the biggest draw. A full asphalt shingle roof on a typical 2,000 sq ft LA home runs $8,000-$14,000 installed. The material is widely available, and most roofing crews can install it quickly, often in 1-2 days.
Asphalt also comes in dozens of colors and styles. It blends with almost any home design, from ranch homes in Northridge to Craftsman bungalows in Pasadena.
Drawbacks of Asphalt Shingles
Heat is the enemy. LA’s long summers and intense UV exposure break down asphalt faster than in cooler climates. Granule loss accelerates, and shingles curl at the edges. A 30-year shingle in Oregon might only last 20-25 years in the San Fernando Valley.
Asphalt absorbs heat rather than reflecting it. Your attic temperature climbs higher, and your AC works harder. On a 100-degree Valley day, a dark asphalt roof can hit 170 degrees at the surface.
What Is Metal Roofing?
Metal roofing covers several materials: standing seam steel, aluminum panels, corrugated metal, and stone-coated metal tiles. Standing seam is the most popular choice for residential homes in LA.
Types of Metal Roofing
- Standing seam uses interlocking panels with raised seams. Clean, modern look. Best wind resistance.
- Corrugated metal has a wavy profile. Lower cost, common on ranch and agricultural-style homes.
- Stone-coated steel tiles mimic the look of clay or concrete tile. Good option for neighborhoods with strict HOA rules.
Advantages of Metal Roofing
A metal roof lasts 40-70 years depending on the material. Standing seam steel with a Kynar finish can go 50+ years with minimal maintenance.
Metal reflects solar radiation instead of absorbing it. A light-colored metal roof can reduce cooling costs by 10-25% compared to dark asphalt. In a city where AC runs six months a year, that adds up.
Metal handles Santa Ana winds well. Standing seam panels interlock and resist uplift at speeds of 120-140 mph. Asphalt shingles start lifting at 60-70 mph.
Fire resistance is another factor. Metal carries a Class A fire rating, the highest available. For homes near hillside fire zones in Malibu, Pacific Palisades, or Chatsworth, that matters.
Drawbacks of Metal Roofing
Cost. A standing seam metal roof on a 2,000 sq ft home runs $18,000-$30,000 installed. That is roughly double the price of architectural asphalt shingles.
Metal can also dent from falling branches or large hail. Aluminum dents more easily than steel. Repairs require matching the exact panel profile, which can be harder than swapping a few shingles.
Noise is a concern some homeowners raise. Rain on metal is louder than rain on asphalt. Proper underlayment and attic insulation reduce this, but it doesn’t disappear completely.
Head-to-Head: Metal vs Asphalt in Los Angeles
Here’s how the two compare on the factors that matter most in LA.
Cost
Asphalt wins on upfront price. $8,000-$14,000 vs $18,000-$30,000 for metal. But over a 50-year period, metal often costs less because you avoid a second replacement. One metal roof outlasts two asphalt roofs.
Lifespan
Metal lasts 40-70 years. Asphalt lasts 15-30 years, often closer to 20 in LA’s heat. If you plan to stay in your home long-term, metal’s lifespan is a real advantage.
Energy Efficiency
Metal reflects more heat. A cool-rated metal roof can keep your attic 20-30 degrees cooler than a standard asphalt roof. In Los Angeles, that translates to real savings on your energy bill, and it helps meet California’s Title 24 energy requirements.
Wind Resistance
Standing seam metal resists winds up to 140 mph. Architectural asphalt shingles are rated for 110-130 mph but can lose individual shingles in gusts above 70 mph. If you live in a canyon or hillside area where Santa Ana winds hit hardest, metal has an edge.
Fire Rating
Both can achieve Class A ratings. Metal is inherently Class A. Asphalt needs a fire-resistant underlayment system to qualify. In California’s WUI (Wildland-Urban Interface) zones, Class A is required regardless of material.
Maintenance
Asphalt needs more attention. You should inspect for granule loss, lifted shingles, and cracked sealant strips every 2-3 years. Metal needs less frequent maintenance but should still be checked for fastener corrosion and sealant failure at panel joints.
Which One Makes Sense for Your Home?
Your budget, timeline, and priorities determine the right answer.
Asphalt shingles make sense if you need a lower upfront cost, plan to sell the home within 10-15 years, or have a straightforward roof with easy access. They are also the better fit if your neighborhood has a traditional look and metal would stand out.
Metal roofing makes sense if you plan to stay in your home for 20+ years, want lower energy bills, live in a fire zone, or face consistent wind exposure. The higher upfront cost pays for itself over time through longevity and energy savings.
There is no wrong answer between these two. Both are solid choices for LA. The right pick depends on your situation, not on which material is “better.”
Frequently Asked Questions
How long does a metal roof last compared to asphalt shingles?
Metal roofs last 40-70 years. Asphalt shingles last 15-30 years, and in LA’s heat, that range skews toward the lower end. A single metal roof will typically outlast two full asphalt shingle installations.
Is a metal roof worth the extra cost in Los Angeles?
For homeowners staying long-term, yes. The energy savings alone (10-25% on cooling) offset some of the price difference. You also avoid a second roof replacement. Over 50 years, total cost of ownership is often lower with metal.
Do metal roofs make a lot of noise when it rains?
Modern metal roofs installed over solid decking and proper underlayment are not dramatically louder than asphalt. You may notice rain more, but with attic insulation, the difference inside the home is minimal.
Can I put a metal roof over existing asphalt shingles?
In some cases, yes. Light metal panels can be installed over one layer of asphalt shingles, which saves on tear-off costs. But it depends on the condition of the existing roof and local building code. A roof inspection will determine if an overlay is possible.
Are metal roofs good for fire protection in California?
Metal carries an inherent Class A fire rating. It won’t ignite from embers or radiant heat. For homes in or near California’s WUI zones, metal is one of the strongest choices for fire resistance, alongside clay and concrete tile.
Which material handles Santa Ana winds better?
Standing seam metal has the edge. Interlocking panels resist uplift at 120-140 mph. Asphalt shingles, even premium architectural ones, can lift or tear in gusts above 70 mph. Homes in canyon and hillside areas benefit from metal’s wind performance.
The Bottom Line
Metal and asphalt shingles both work well for Los Angeles homes. The decision comes down to your budget, how long you plan to stay, and what conditions your roof faces.
