Shingle Roofers in Los Angeles, CA
Shingle roofers in Los Angeles, CA install and repair asphalt composition shingles, the most common roof covering on the county's postwar tract homes. The two grades are 3-tab and architectural, and the difference shows up in price and in years of life. A roofer measures the roof, shows both grades if they fit the budget and writes one figure.

What shingle roofers install: 3-tab and architectural
3-tab shingles are the thinner, flatter, cheaper grade, rated at about 20 years by InterNACHI. Architectural shingles are thicker and layered, rated at about 30 years [thisoldhouse.com, updated 2026-04-07]. Brands such as GAF, Owens Corning and CertainTeed make both, and the estimate names the product line so the homeowner can read its warranty.
Shingle repair or a new shingle roof
Missing, curled or cracked shingles on a younger roof are a repair. A roof with widespread curling, bare spots or granule loss is a replacement. The roof replacement page covers the full tear-off, and roof repair covers the small jobs.
What shingles cost
HomeAdvisor's 2024 page puts installed asphalt shingles at $4 to $12 a square foot and a typical roof at $6,119 to $13,804. The written estimate gives the figure for the actual roof, and the roof replacement cost guide explains the drivers.
Shingles and Los Angeles heat
Constant sun dries out the asphalt and loosens the granules that protect it, and a Los Angeles shingle roof can wear faster on the south and west slopes. A residential replacement over half the roof area in the city calls for a Cool Roof Rating Council rated covering [LADBS bulletin IB P/GI 2020-003], so the product choice is partly set by the permit.
Shingle roofers questions, answered
What is the best shingle for a Los Angeles roof?
Architectural shingles last longer than 3-tab, and a cool-roof-rated product is needed for large residential replacements in the city. The estimate lists the options that fit the house.
How long do asphalt shingles last?
About 20 years for 3-tab and about 30 for architectural, per InterNACHI, with sun exposure shortening both.
Can a few shingles be replaced without a new roof?
Yes, on a roof with life left. The roofer matches the shingle as closely as the age of the roof allows.
