Asphalt Shingle (Architectural / Designer)
The LA value default — $8-$15/sf installed, 25-30 year warranty, Class A fire rating, widest installer network.
Strengths
- Lowest installed cost — half of metal, two-thirds of tile
- Class A fire rated — WUI compliant for LA hillside zones
- Widest installer network in LA — fastest scheduling
- Wide range of colors and architectural patterns
Weaknesses
- Shortest lifespan of the three — 25-30 years
- Heat absorption — typical dark shingle adds $200-$400/year to AC bill in LA summers
- Hail/wind damage requires individual repair (not common in LA but happens)
- Granule loss over time — degrades curb appeal at year 15-20
Asphalt's hidden cost is the cooling penalty. A dark-color architectural shingle absorbs ~80% of solar heat vs. ~30% for cool-roof colors. LADWP offers $0.20-$0.30/sf rebates for cool-roof rated shingles (LRV ≥0.20). Always spec cool-roof rated colors — same cost, $200-$400/year less on AC bills.
Best for: Mid-market LA renovation, rental properties, and any home where the homeowner plans 15-20 year hold and wants the most-installed material on LA streets.
