AfterFast, Reliable Roofing Across Commerce
Roofing in Commerce works differently than it does in Bell Gardens or Montebello. Most of this city is tilt-up concrete, standing-seam metal, and warehouses built between the 1950s and 1980s. A residential roofer who spends all day on shingle homes will not recognize what fails on an industrial roof here. We do. Barrett & Sons Construction has been called out to Commerce warehouses and the small residential enclave off Bandini Boulevard enough times to know the failure patterns before we climb the ladder. If you need a leak diagnosed, a roof replaced, or a pre-1990 building brought up to current seismic code, call Tom’s team at (877) 610-1318.
Why Barrett & Sons Construction Is Commerce’s Preferred Roofing Company
We are the owner-operated alternative to the big outfits. Tom Barrett founded this company in 1998, and his sons run crews. When you call about a roof in Commerce, you get a live person who knows the difference between a warehouse reroof and a house re-shingle, because we have done both here. Our name is on the truck. Our license number is published and verifiable, and so is our address. Ask around, or look us up yourself before you sign anything.
Commerce customers do not call us because we are the cheapest. They call because the previous contractor quoted one price and showed up with another. Every scope change on our jobs arrives as a written change order before a single fastener moves. Every eligible job gets permits pulled and inspections signed. And every job, residential or industrial, carries our 90-Day Done Right Promise in writing: if it is not right, Tom comes back and makes it right. One call.
We also answer the phone 24 hours a day. Not a call center. A person. When a storm blows a panel loose on a warehouse off Eastern Avenue at midnight, someone picks up.
Our Roofing Services in Commerce
For a city built on logistics and distribution, the Roofing work that matters most is industrial. We handle residential roofs too, in the small pocket of homes near Commerce Casino and the 90101 ZIP code, but the bulk of what we do here is commercial and industrial roof replacement, repair, and code compliance. These are the four services Commerce calls us about most.
Roof Repair
Roof repair in Commerce typically runs $400 to $1,800, depending on what has failed. On the industrial side, we most often repair panel laps that have loosened from thermal cycling. Commerce sits inland, away from the coastal marine layer, and summer temperatures run noticeably hotter than in Maywood or Bell. That expansion and contraction loosens standard carbon-steel fasteners on standing-seam metal roofs until water finds a seam. We replace with stainless, re-seal the lap, and the leak stops for good.
Roof Replacement & Installation
A full roof replacement in Commerce runs $8,000 to $20,000 for residential and small commercial, and higher for large industrial buildings depending on square footage and code upgrades. Before we pull the permit, we inspect parapet connections and rooftop equipment anchorage. Many Commerce tilt-up buildings predate current CBC seismic requirements. If the parapet is under-anchored or the rooftop HVAC is sitting on undersized bolts, that gets fixed as part of the reroof, in writing, before we start. The inspector works for you, not for us, and we want him satisfied.
Metal Roofing
Metal roof installation in Commerce runs $15,000 to $40,000, and most of what we install is standing-seam on industrial buildings. This is the right roof for this city’s heat and diesel exhaust, but only if the hardware is right. Cheap coated steel fasteners corrode here faster than inland-expectation would suggest, because diesel particulate from the I-5 and the surrounding truck arterials settles on rooftops and mixes with acid rain. We specify hot-dip galvanized clips and stainless screws, and the roof lasts decades instead of failing at the seams in year eight.
Tile Roofing
Tile roof repair in Commerce runs $600 to $2,500. Tile is rare here, but the residential enclave near the 90101 ZIP has some mid-century homes with clay and barrel tile. Those roofs are aging, and the underlayment is usually the problem, not the tile itself. We lift, replace the paper, reset the tile, and repoint the ridges. The tile gets reused when it is sound.

Trusted Brands We Service in Commerce
We install and service roofing systems from GAF and CertainTeed, and we keep common fasteners, sealants, and flashing stock on hand for Commerce jobs so a repair does not stall waiting on a parts order. For window and door work tied to roof and parapet retrofits, we work with Simonton and Ply Gem. No mystery materials off the back of a van. Everything we install is a brand you can look up.
What fails on Commerce roofs is not the panel. It is the hardware. So we use what actually survives this city’s specific conditions: hot-dip galvanized clips, 300-series stainless screws, and marine-grade sealant at every lap. The cheap spec works in a drier, cleaner climate. Not here.
Common Roofing Problems We See in Commerce Homes
- Loose standing-seam laps from thermal cycling. Commerce runs hotter than the beach cities in summer, and the panels on a metal roof expand noticeably. Standard carbon-steel fasteners back out over time, the laps open, and rain finds the gap. Stainless screws and proper clip spacing stop it.
- Corroded parapet caps and edge flashing. Years of diesel exhaust from truck traffic on the I-5 and the surrounding arterials settles on roof edges, mixes with rainwater, and eats standard galvanized flashing. Water then gets into the tilt-up wall panels and rusts the embedded steel. We see this on nearly every pre-1990 building.
- Undersized or corroded rooftop HVAC anchors. On many older Commerce warehouses, the rooftop units are held down with wedge bolts that were undersized even when new and have since corroded. Current CBC seismic anchorage requires better. If we find this during a reroof, we epoxy-set new anchors and add a properly sized curb before the inspector arrives.
- Unpermitted mezzanines discovered during a roof job. This one surprises homeowners and building owners. When we strip an old roof on a Commerce tilt-up, we sometimes find a mezzanine or storage platform that was added years ago without permits and is now undersized for current load-bearing standards. It has to be brought up to code before the new roof and occupancy permit can finalize. That is a written change order, not a surprise invoice.
Pricing for Roofing in Commerce, CA
Here is what roof work actually costs in Commerce right now, based on what we have quoted and completed in this city, not a national average.
| Service | Commerce Price Range |
|---|---|
| Roof Replacement | $8,000 - $20,000 |
| Metal Roof Installation | $15,000 - $40,000 |
| Roof Repair | $400 - $1,800 |
The gap between a cheap coated-steel standing-seam roof and the one we specify is real, and it shows up in the hardware, not the panel. An inland-spec metal roof with carbon-steel fasteners might save a few thousand dollars up front. In Commerce, within a decade, the fasteners rust, the laps open, the leaks start, and the repair bill erases the savings. The coastal-spec roof with stainless and hot-dip galvanized costs more on day one and is still dry on year twenty.

FAQs - Roofing in Commerce
Yes. Any roof replacement on a commercial or industrial building in Commerce requires a permit, and the inspection will check more than the panels. The inspector will verify parapet anchorage, rooftop equipment seismic fastening, and edge flashing details against current CBC standards. If the building is pre-1990 and the anchors are undersized, the permit process forces those corrections. We pull permits on every eligible job, and we prefer it that way. The permit inspector works for you, not for us. Call (877) 610-1318 if you want to know what your specific building will require.
Because standard coated steel fasteners fail in Commerce’s specific air. Diesel particulate from truck traffic on the I-5 and surrounding arterials settles on rooftops, mixes with acid rain, and corrodes standard hardware faster than the same roof would corrode in a cleaner city. Stainless screws and hot-dip galvanized clips cost more and last decades. We put the reason in writing, but if you want the cheaper spec, we will install it; we will also tell you what it will look like in ten years. Call for a line-item quote.
We stop that portion of the work and issue a written change order with a specific price before anything else moves. An allowance that is not on paper is a surprise waiting for a date. If the mezzanine or equipment anchor must be corrected to pass inspection, that work gets scoped, priced, and signed before we proceed. No surprise invoices at the end. Call (877) 610-1318 and Tom will walk you through how change orders work on your building type.
On days when the South Coast Air Quality Management District restricts construction activity due to high pollution, roof work on large industrial buildings in Commerce must be rescheduled or scaled back. We track AQMD notices and plan roof tear-offs and adhesive application around the worst days. It can add a day or two to a big reroof schedule. We build that into the project plan before we start, not as an excuse after we have fallen behind.
For most Commerce warehouses, yes. The math favors metal because of the city’s heat. A built-up asphalt roof absorbs more heat and ages faster in Commerce’s inland summer temperatures, while a standing-seam metal roof reflects more heat and expands and contracts predictably when the hardware is right. The upfront number is higher, but the replacement cycle is longer, and the cooling load inside the building drops. For a warehouse that runs hot already, that difference is noticeable in the first full summer.
