Roofers in Commerce, CA
Roof inspection in Commerce starts with understanding what this city’s buildings actually face: shallow-pitch 1950s tract homes and flat-roofed warehouses packed between the 5 and 710 freeways, all under the same harsh LA Basin sun. We look for what Commerce roofs do wrong, which is plenty specific: ponding water on low-slope membranes, UV-baked shingle edges, and flashing that fails where homes share walls with commercial buildings. If your roof is leaking, losing granules, or simply draining poorly, call (877) 755-4274 and we’ll tell you exactly what your roof needs – and what it doesn’t.
Why Commerce Homes Are Different
Commerce isn’t a typical bedroom community. The city is a five-square-mile industrial hub tucked between railroad yards, warehousing corridors, and the 5/710 interchange, and its housing stock reflects that split personality. Post-World War II stucco tract homes from the 1950s and 60s sit on streets that back directly onto loading docks and freight lines. Many of those homes have low-slope or shallow-pitch roofs, which means they drain slowly and hold water long after a winter storm passes. The commercial side of Commerce is dominated by flat membrane roofing, hot-mop and modified bitumen, over warehouses and small manufacturing buildings.
The climate here works against every roof type. Commerce sits in the LA Basin, where summer temperatures regularly push past 90 degrees and the sun beats down without the coastal marine layer that cools cities to the west. That constant UV exposure dries out shingle surfaces and accelerates membrane cracking on flat roofs. Then Santa Ana winds arrive in the fall, peeling loose flashing and stripping granules from asphalt shingles before the winter rains test every seam. Roofs in Commerce don’t age gracefully; they age visibly and then they fail during the first sustained rain event.
One thing that defines roofing work in Commerce more than almost anywhere else: how close the buildings are. Many residential roofs sit within a few feet of a neighbor’s wall, and a huge number of commercial roofs tie into the building next door. Tie-in flashing has to be matched to a different roof system on a structure you don’t own. That’s not a job for a generalist. It takes a roofer who has worked both shingle and membrane systems in the same block.
Styles & brands we work with






Our Main Commerce Services
Homeowners in Commerce usually call us about two things: a leak that won’t stop, or a roof that’s reached the end of its life. Here’s how each plays out in this city.
Roof Repair in Commerce
Most repairs in Commerce involve low-slope drainage problems, degraded flashing around vents and parapet walls, or shingle damage from Santa Ana winds. Because so many homes in Commerce back up to industrial buildings, we also handle a lot of tie-in flashing work where residential roofs meet commercial walls. We inspect first, identify the exact point of failure, and repair only what’s failing. See how we approach Roof Repair in Commerce.

Roof Replacement in Commerce
When a Commerce roof has exhausted its service life, replacement is the honest call. That means tearing off old shingles or membrane, repairing the deck where needed, and installing a system matched to the building’s drainage pattern and sun exposure. For Commerce’s flat and shallow-pitch housing stock, material choice matters more here than in steeper-pitch cities. We walk every homeowner through the tradeoffs before any work begins.

Roof Inspection in Commerce
A Roof Inspection in Commerce does something no YouTube video can: it puts an experienced roofer on your roof to read what the LA Basin weather has done to it. Homes here were built in the 1950s and 60s, most with low-slope or shallow-pitch roofs that pool water and bake under summer UV. We inspect every roof as a system: covering, flashing, drainage, and the spots where Commerce’s close-packed construction creates conflict points. You get a clear diagnosis and an honest recommendation, whether that’s a $600 repair or a roof approaching replacement age.

What Commerce Customers Say
"Full replacement after the hail. They handled the insurance adjuster meeting, documented everything, and I did not have to argue with anybody. Crew was here three days and the yard was cleaner when they left than when they started."
— Marco Mendoza"He told me my roof had another five or six years in it and I should not replace it yet. He was standing there with a quote pad in his hand. That's why I'll call him when it's time."
— Karen Kim"Roof is solid and the price was competitive. The job ran a day over because of weather, which is nobody's fault, but I would have liked a call about it rather than noticing the crew hadn't shown up."
— Robert Fletcher
