Roofing Contractor in Commerce, CA

Who permits a Commerce roof, and where Los Angeles County fits

Commerce is an incorporated city in southeast Los Angeles County. Building permits run through the City of Commerce, not LADBS, so check any quote written for a Los Angeles address against the city's process. Any roofing contract should say which party applies and which party calls for inspection.

State rules still apply here. California stops a re-roof from going over two existing applications, and a replacement past the half-roof mark generally calls for a cool-rated product. Low-slope and steep-slope roofs follow different requirements, and the California Energy Commission's zone lookup tells you which apply to your address.

Rail-era warehouse roofs between the Santa Ana and Long Beach freeways

Commerce grew around the Santa Fe main line, which came through in 1887. Factories followed, then the warehouses that dominate the map today. Those buildings have large flat or low-slope roofs, often with interior drains, scuppers, skylights and rooftop equipment.

Large roofs fail in small places. A cracked curb flashing, a clogged drain or a worn walk path near equipment can start a leak that shows up at a distant ceiling.

We start any commercial assessment with the drains, then the seams, then every penetration. Our commercial roofing and flat roofing pages explain the systems we quote, and the right fix on a big roof is often a section, not the whole building.

Bandini, Rosewood and Laguna: Commerce's residential roots

Before the 1960 incorporation, residents of the communities of Bandini, Rosewood and Laguna worked with industry leaders to promote the area, and the name Commerce came out of that effort. The homes that sit among the industry today are mostly small and postwar. Census ACS puts the median build year at 1957, with 55% owner-occupied.

Those roofs have often been re-covered once or twice. A house a block from a warehouse wall sees heat, dust and runoff, and a worn shingle roof shows it early.

The Citadel, the rail yard and the Commerce Casino: big buildings under one city

Commerce's landmarks are large, and so are their roofs. The Citadel Outlets stands on the site of a former tire factory, a major rail yard lies within the city limits, and the Commerce Casino card club funds many city services. The city covers 6.5 square miles at about 141 feet above sea level, so buildings spread out wide and flat.

Alongside them are 3,524 housing units, and 52.7% of occupied units were rented in 2020. On a rental house or a multi-tenant commercial building, the person who calls us is rarely the person who signs, so we write the scope so an owner or property manager can approve it from photos. Montebello Unified serves most of the city, with Los Angeles Unified covering small portions.

Roof visits in Commerce from Van Nuys

Allow roughly 45 minutes, though the 5 and the 710 can stretch that, by our estimate. For a commercial building, we ask about roof access, equipment owners and tenant hours before scheduling.

We photograph and measure, then explain what is minor and what is not. On rooftop equipment, we also check whether foot traffic is wearing a path into the membrane.
