Why Commerce Homes Are Different
Commerce is one of the most intensely industrialized incorporated cities in Southern California - its land use is dominated by warehouses, distribution centers, and light manufacturing rather than residential neighborhoods. That concentrated thermal load from dark industrial rooftops and impervious hardscape pushes ambient temperatures 20-40°F above neighboring cities, accelerating UV degradation and thermal cycling on flat membrane roofs. Fall Santa Ana wind events create negative pressure across unobstructed warehouse rooftops, testing seams and flashings that may already be heat-weakened. The limited residential stock - modest 1940s-1960s bungalows near Rosewood Park - carries original built-up tar-and-gravel or aging composition shingles well past their service life.
Roof Repair in Commerce
Flat roof patch work dominates our call volume in Commerce. The city’s sprawling single-story warehouses and light-manufacturing structures with low-slope roofs demand membrane expertise that residential contractors simply don’t carry. We patch TPO, EPDM, modified bitumen, and built-up gravel systems, matching the repair method to your roof’s age and condition. A typical flat roof patch in Commerce runs $450-$1,200 for spot repairs and $1,800-$2,800 for larger sectional work. Our Roof Repair crews carry the membrane stock and curb-flashing components needed for single-visit completion on standard jobs.
Leak Repair
Leak repair in Commerce requires reading the roof like a map. Water traveling across a warehouse deck can show up ten feet from the breach, and on older built-up gravel roofs, the source hides under layers of tar and aggregate. We trace leaks to their origin, whether it’s a failed TPO seam on a 1990s overlay or a pinhole in original four-ply felt. Most Commerce leak repairs are diagnosed and stopped same-day, with costs ranging from $180 for simple residential flash leaks to $850 for commercial membrane tracing and sealing.
Flashing Repair
Flashing repair protects the joints where your roof meets walls, curbs, and penetrations. In Commerce’s warehouse district, rooftop HVAC curbs are a chronic failure point - original sheet metal rusts through, and tar counter-flashing cracks under decades of thermal cycling. We fabricate and install proper galvanized or aluminum flashing, sealed with manufacturer-approved compounds. For residential bungalows near Bandini Boulevard or the 5 Freeway corridor, we replace deteriorated step flashing and valley metal, critical where original 1940s-1960s shingles have curled past saving. HVAC curb reflash work typically runs $380-$720.
Should I repair or replace my 1950s built-up gravel roof if it has multiple blisters?
Repair is viable if less than 25% of the field shows blistering and the underlying substrate is dry; replacement becomes the smarter spend when blisters cluster across more than a third of the roof or you have repeated leaks in multiple zones. We photograph the damage, probe for wet insulation, and give you a straight recommendation. Call (877) 367-1429 for an exact quote - estimates are free.
Roof Replacement & Installation in Commerce
Roof replacement in Commerce runs heavily toward commercial flat-roof membrane systems rather than residential shingles, with typical full replacements for industrial buildings ranging from $8,500 for smaller warehouse re-roofs to $45,000+ for large distribution centers. Our crews are on Commerce roofs year-round, and we usually inspect within 24 hours of your call. We’re the anti-storm-chaser: founded in 1984, we hire local crews and plan to be here in thirty years.
Full Roof Replacement
Commerce has a concentrated backlog of commercial re-roofing work packed into a single 6-square-mile city. A significant share of older industrial buildings date to the 1950s-1970s postwar manufacturing surge and still carry original four-ply built-up gravel roofing long past its rated lifespan. We strip these legacy systems, assess the structural deck for deterioration from years of ponding and leaks, and install modern membrane assemblies. Small warehouse TPO re-roofs run $8,500-$14,000; mid-size distribution centers with tapered insulation range $18,000-$32,000.
Flat Roofing
Flat roofing is the bread and butter of Commerce. We specify membranes and attachment methods rated for the city’s amplified heat-island conditions and fall Santa Ana wind events, paying particular attention to parapet wall flashing details that fail first under wind uplift. Our Roof Replacement & Installation work includes full manufacturer-warrantied systems from GAF and CertainTeed, installed to spec so the warranty actually transfers. Large industrial built-up tear-offs and membrane replacements typically run $35,000-$55,000+.
Can I replace my old built-up gravel roof with TPO on my Commerce warehouse?
Yes, and in most cases you should. TPO offers superior reflectivity, lighter weight, and longer warranty terms than aging four-ply built-up systems. We strip the old gravel roof, assess the structural deck, install proper insulation and tapered crickets for drainage, then fully adhere or mechanically attach the TPO membrane per wind-uplift requirements. Call (877) 367-1429 to schedule an inspection.
Specialty Roofing in Commerce
Specialty roofing in Commerce runs almost entirely to commercial flat-membrane systems, with typical TPO installations ranging $8.50-$14.00 per square foot and built-up roof recoveries running $6.00-$10.00 per square foot. Most warehouse and distribution center jobs in the 90101 ZIP code can be inspected within 24 hours. Dispatch and scheduling are coordinated from our Los Angeles office; crews serve Commerce locally with the membrane stock and curb-flashing components for single-visit completion.
TPO Roofing
TPO single-ply membrane is our most specified system for Commerce warehouse re-roofs. The white reflective surface fights the amplified heat load on industrial rooftops in this dense hardscape zone. A typical TPO installation on a 20,000-square-foot Commerce distribution center runs $170,000-$280,000, with most jobs completed in 5-10 business days depending on HVAC curb complexity. We recently re-roofed a 1962 distribution center on Randolph Street, stripping the original four-ply built-up gravel and installing a GAF TPO system with pre-engineered curb flashings.
Built-Up Roofing Recovery
Built-up roofing - the tar-and-gravel systems covering so many of Commerce’s 1950s-1970s industrial buildings - is a specialty we’ve maintained as other contractors abandoned it. Recovery with a new modified bitumen cap sheet runs $6.00-$8.50 per square foot if the substrate is sound. Full tear-off and replacement hits $8.00-$12.00 per square foot when probing reveals saturated insulation or rusted metal decking. Our Specialty Roofing crews probe these decks carefully - what looks recoverable can hide serious damage.
Why do flat roofs on Commerce warehouses fail more often than in neighboring cities?
Commerce’s exceptional density of dark industrial rooftops and impervious hardscape creates a heat island effect that accelerates UV degradation and thermal cycling beyond what residential-zone membranes endure. Fall Santa Ana wind events add uplift stress on large, unobstructed warehouse decks. The combination means Commerce flat roofs work harder and age faster. Call (877) 367-1429 for an inspection - estimates are free.
Gutters & Accessories in Commerce
Gutter installation and repair in Commerce typically runs $1,200-$3,800 for most residential jobs, with same-week scheduling available. Our crews know the difference between a quick fix on a standard system and the custom fabrication required for Commerce’s limited but aging housing stock, where original 1940s-1960s fascia and gutter systems often need tailored solutions.
Gutter Installation
New gutter installation in Commerce demands more than measuring and hanging. Original fascia and gutter systems on postwar bungalows are often incompatible with modern seamless profiles due to non-standard slope and bracket spacing. We fabricate seamless aluminum gutters on-site to match your existing roofline. A typical residential installation runs $1,800-$3,200, including removal of the old system, fascia inspection, and proper pitch calculation.
Gutter Repair
Repair work is where we spend much of our time in Commerce. Separated seams, sagging channels from failed spikes, and rotted fascia behind leaking corners are standard on systems that have baked through forty LA Basin summers. We replaced a failing legacy galvanized system on a 1950s bungalow on Indiana Street, fabricating custom seamless aluminum gutters with offset downspout adapters to match unusual bracket spacing. Most repairs run $250-$850. Our Gutters & Accessories team handles both residential seamless gutters and commercial box gutters, scuppers, and downspout systems.
Is gutter work in Commerce more expensive than in neighboring cities?
Commerce gutter work often runs higher than standard residential pricing in Maywood or Bell due to custom fabrication for non-standard legacy systems. A typical seamless gutter job in Commerce is $1,800-$3,200 versus $1,500-$2,800 in more standardized housing markets. The difference pays for proper fitting rather than forcing incompatible modern parts onto old fascia. Call (877) 367-1429 for a free estimate specific to your home.
Emergency & Storm Damage in Commerce
When Santa Ana winds tear at your roof in Commerce, you need a crew that understands what fails here and why. Emergency tarping and storm damage repair typically runs $400-$1,800 for membrane stabilization, with our team usually on-site within 60-90 minutes of your call. We answer live around the clock - no voicemail, no callback windows, no leaving a homeowner or facility manager stranded.
Wind Damage
Wind damage in Commerce is almost exclusively a flat-roof problem. Santa Ana events generate negative pressure across expansive warehouse rooftops, lifting membrane seams and peeling perimeter flashings. We arrive with mechanical fastening equipment, seam reinforcers, and GAF EverGuard products specified for high-uplift zones. Emergency stabilization runs $800-$2,500; full seam recovery on a large roof can reach $4,000-$8,000.
Emergency Tarp
When a membrane blow-off exposes insulation and decking, emergency tarping buys time. In Commerce, this means large-format reinforced poly sheeting secured with perimeter ballast or mechanical fastening - not the blue residential tarps you’ll see in surrounding cities. We stock 10-foot and 20-foot rolls rated for high wind. Emergency tarp deployment runs $400-$1,200 for a standard commercial section, including same-day installation. Our Emergency & Storm Damage crews can schedule permanent repair within 48-72 hours.
Can you provide emergency tarping during active Santa Ana winds?
We deploy emergency tarping during Santa Ana events when conditions allow safe access - typically when sustained winds drop below 35 mph and lift equipment can operate. Our reinforced poly sheeting is rated for high wind and secured with perimeter ballast or mechanical fastening appropriate for the roof substrate. For a standard 20,000-square-foot distribution center section, emergency tarp runs $400-$1,200 with same-day installation when dispatched during business hours. Call (877) 367-1429 - a live person answers 24/7.

FAQs About Roofing in Commerce
Commercial roof replacements in Commerce require a building permit from the City of Commerce Community Development Department, with submittal of manufacturer specifications, insulation R-value calculations, and wind-uplift documentation.

What Commerce Customers Say
"Went up in the attic first with a flashlight before going on the roof, which no other estimator bothered to do. Found the stain and worked backward from there."
- Beatriz Morales"Added a ridge vent and cleared the blocked soffit vents. The attic temperature dropped noticeably and the upstairs is livable in summer now."
- Simone Grant"Three cracked tiles and one that had slipped. Matched the tile, no color mismatch, half a day of work."
- Darius Prince
