AfterFast, Reliable Roofing Across Commerce
Roof repair in Commerce is a different animal than it is twenty minutes west in Bell Gardens. Most of what we put roofs on in Commerce is tilt-up concrete, not wood framing. A warehouse roof here has to hold up under summer heat that regularly runs 10 to 15 degrees hotter than the coast, diesel particulate drifting off the I-5, and seismic code most of the buildings predate. We’ve been coming into Commerce for years to do exactly that work, and we answer the phone at (877) 610-1318. If your roof’s failing, call us. We’ll come look at it, write up a real scope, and tell you what it costs before you sign anything.
Why Barrett & Sons Construction Is Commerce’s Preferred Roofing Company
Tom Barrett started this company in 1998, and his name is on the truck, the contract, and the license. When a warehouse owner off Eastern Avenue or an operator out near the 90101 corridor calls, we show up on time, we pull permits, and we put every price change on paper before it happens. You want a roofing contractor in Commerce who won’t disappear after the deposit. We live close enough that walking away from a bad job would follow us to the hardware store. It hasn’t yet, and it won’t start here.
The work we do in Commerce runs deeper than tear-off and re-cover. The city’s industrial buildings, most of them built between the 1950s and 1970s, were put up before LA County tightened seismic anchorage rules for rooftop equipment. That means a lot of the roofs we touch also need HVAC curbs rebuilt, gas lines re-braced, and ledger connections brought up to current CBC standards before the inspector signs off. Most roofing outfits won’t mention that until mid-job. We write it into the scope from day one.
You can look up our license before we ever set foot on your roof. We’d tell you to. Tom publishes his name and license number because the last contractor most Commerce property owners hired told them permits were optional. That’s not how we work, and it never will be.
Our Roofing Services in Commerce
Roofing in Commerce breaks down into the work we do most often out here. Here’s what that looks like.
Roof Repair
Most Commerce roof repair calls start with a leak, but they usually end with us finding something bigger underneath. Thermal expansion cracks at roof-to-wall transitions on flat industrial roofs are common here because the city sits at the eastern edge of the LA Basin, away from the marine layer that keeps coastal cities cooler. We repair the leak, but we also address what caused it, so you’re not calling us again in six months.
Roof Replacement & Installation
Roof replacement in Commerce isn’t just swapping panels. On a 1960s tilt-up, the roof deck has likely seen decades of expansion and contraction, and the original fasteners may be undersized and corroded. We spec hot-dip galvanized hardware and seismic-certified curbs so the new roof doesn’t inherit the old one’s problems. A typical replacement here runs $8,000 to $20,000 depending on deck condition and equipment count.
Metal Roofing
Standing-seam metal is the right roof for Commerce’s industrial stock, but only if it’s fastened correctly. We see galvanic corrosion at panel-to-panel seams where untreated steel fasteners were driven into aluminum panels. Add diesel particulate from I-5 truck traffic and the metal breaks down faster than it should. We use coastal-spec fasteners and sealed seams, and we explain why that matters before you compare bids.
Tile Roofing
Tile is less common on Commerce’s commercial buildings, but the residential pocket near the city’s small housing enclave has some mid-century homes with clay and concrete tile. Those roofs run hot, and the underlayment breaks down from long exposure to basin heat. We repair and replace tile on homes throughout Commerce, including the modest single-family streets that sit tucked behind the industrial corridors.

Trusted Brands We Service in Commerce
We carry premium materials and work on what’s already up there, too. On Commerce roofs we regularly service GAF and CertainTeed systems, and for window and door work on the small residential stock in town we install Simonton, Ply Gem, and PGT frames. When you need parts, we keep common fasteners, sealants, and curb components in local stock so we’re not waiting on a supplier run to finish your repair. You’re running a business or living in a home, not funding our logistics delay.
Common Roofing Problems We See in Commerce Homes
- Galvanic corrosion at panel seams. Untreated steel fasteners against aluminum standing-seam panels create a battery effect, and Commerce’s diesel-heavy air accelerates it. Seams open up, water gets in, and the roof fails from the inside out. We replace fasteners with hot-dip galvanized or stainless and reseal every seam we touch.
- Thermal expansion tears at roof-to-wall transitions. Commerce routinely sits 10 to 15 degrees hotter than coastal cities in summer. Large flat industrial roofs expand and contract in those swings, which tears the transition flashing. We install expansion-compatible details that flex instead of split.
- Failed rooftop HVAC curbs and unbraced mechanical units. Pre-CBC anchorage on older tilt-ups means rooftop units can shift under seismic load, which cracks the deck and pulls the curb loose. Before we re-roof, we assess the anchorage and bring it up to code, sometimes through a written change order if the scope changes.
- Unpermitted mezzanines tied into roof ledgers. We find these on tenant improvements all over Commerce. Built years ago without permits, the connections to the roof structure are often undersized. You can’t get a clean occupancy permit until they’re fixed, so we fold the remediation into the roofing scope.

FAQs - Roofing in Commerce
Yes, in most cases. Like-for-like panel swaps on industrial tilt-ups in Commerce still trigger permit requirements when the deck, curbs, or anchorage are involved, and they almost always are once we open up the roof. The City of Commerce building department and LA County review roofing work on commercial buildings for seismic and structural compliance. We pull every permit ourselves and never tell a customer that one is optional. Call (877) 610-1318 if you want us to check your specific building.
The short answer is heat plus diesel particulates. Commerce runs hotter in summer and sits under heavy I-5 truck traffic. That combination attacks the fasteners and sealants at panel seams, especially when someone used untreated steel fasteners against aluminum panels. Bell Gardens gets less of both, so the same roof lasts longer there. In Commerce, we spec hot-dip galvanized or stainless fasteners and marine-grade sealant at every seam. If your roof is failing at the seams, call us for an exact diagnosis and a written quote.
Expect roughly 10 to 20 percent more upfront for coastal-spec fasteners, seals, and curb detailing on a Commerce metal roof. On a $15,000 to $40,000 metal roof installation, that’s a meaningful difference, but the inland-spec quote looks cheap until the seams open in five to eight years and you’re paying for a second repair. We show both options in writing and let you choose. Call (877) 610-1318 for a line-item comparison.
We stop, document it, and write a change order before we touch it. In Commerce, unpermitted mezzanines tied into roof ledgers on older tilt-ups are common, and the connections are often undersized for current CBC seismic standards. You can’t just roof over it and hope the inspector misses it. We bring the ledger connections up to code, then proceed with the roof. The price change comes to you in writing before any work happens. No surprises at the end.
Yes, and we already do it for our Commerce projects. LA County air-quality regulations can restrict certain construction activity on high-pollution days, particularly along the I-5 corridor where diesel traffic is heavy. We monitor AQMD alerts and phase work on affected days, shifting to interior or shaded tasks where possible, then resume when restrictions lift. It can add a day or two to the schedule, but it keeps your project compliant. Call (877) 610-1318 and we’ll map out a realistic schedule for your building.
