Fast, Reliable Roof Repair Across Commerce
Roof repair in Commerce, CA typically runs $350 – $900 for common fixes like shingle replacement, flashing repair, and leak sealing, while flat commercial roof patches usually land between $600 – $1,400 depending on membrane type and damage extent. We’re in Commerce weekly, and we know the difference between a heat-aged shingle failure on a 1950s tract home and a ponding problem on a flat warehouse off the 5. If you’ve spotted a water stain, missing shingles, or a drain that’s not draining, call us at (866) 650-8319 and we’ll give you a straight read on what’s actually going on.
Our Roof Repair team works from first inspection through final patch, and we don’t hand you off to a sales rep when what you need is a repair, not a replacement.
Why Gable Roof Repair Is Commerce’s Preferred Roof Repair Company
Commerce is a city where the roofing work splits hard between light-industrial flat roofs and mid-century tract homes, and most companies are only really set up for one or the other. We handle both. Our crews work on TPO and modified-bitumen warehouse roofs in the morning and patch oxidized shingles on a 1960s stucco home near Bandini Blvd in the afternoon. That range matters here because the city’s building stock demands it.
Homeowners in Commerce regularly tell us the same thing: they called two or three roofers who pushed a full replacement before anyone had even climbed a ladder. We don’t work that way. Neil Drummond built Gable Roof Repair on a repair-first philosophy, which means our default recommendation is the smallest fix that actually solves the problem. Inspection first, recommendation second. When a repair makes sense, we say so. When a replacement is genuinely warranted, we’ll show you why with photos and measurements. We’re brand-agnostic, we carry material knowledge across seven major shingle manufacturers, and we don’t have a quota to hit on replacements this month.
Response time to Commerce from our Orange County base runs one to two business days for non-emergency work. Leaks and active water intrusion get priority scheduling. You’ll reach a person who can talk about your roof’s actual condition, not a call center script.
Styles & brands we work with
Commercial Roof Repair in Commerce
Commercial Roof Repair in Commerce is a different animal than residential work because of what this city’s economy runs on: rail yards, trucking, warehouses, and light manufacturing. Most commercial roofs here are flat or very low-slope membranes, typically TPO, EPDM, or modified bitumen, and they fail differently than shingle roofs. Heat and UV break down the membrane over time, but the bigger Commerce-specific factor is what lands on the roof from the constant truck and rail traffic along the 5 and 710 corridors. Diesel soot and grit settle on flat roofs, wash toward drains and scuppers during the rare winter rains, and clog them. Water backs up, ponds, and then works its way under flashing and seams. A flat roof that holds water for 48 hours is a leak waiting to happen.
Commercial roof repair in Commerce typically runs $600 – $1,400 for a membrane patch with proper seam work and flashing reseal. Larger damage, drain replacement, or insulation repairs push the number higher. We quote fixed prices with line items, and we pull permits when the scope requires them.
Flat Roof Drainage and Ponding Checks
Before we patch anything on a Commerce flat roof, we clear the drains and scuppers and check where water actually sits. If the roof is ponding in the middle of a field rather than draining, a patch alone won’t last. We’ll tell you that plainly, and we’ll quote the patch and the drainage correction as separate line items so you decide what gets done now.
Membrane Repairs for Warehouses and Shops
TPO and mod-bit membranes can often be heat-welded or torched back to watertight without a full re-roof. We match the existing membrane type rather than slapping on an incompatible patch, because incompatible patches fail at the seam. If the roof is Boral, IKO, or another approved system, we follow that manufacturer’s repair details so the warranty stays intact.
Roof Leak Repair in Commerce
Roof Leak Repair in Commerce usually starts with a stain on a ceiling or a damp spot near a wall, and on the older tract homes that dominate the residential streets, the actual leak source is rarely directly above the stain. Water travels along rafters, follows the slope, and drips at the lowest point. We trace the leak to its origin, because patching the ceiling does nothing for the roof.
Residential leak repair in Commerce typically runs $350 – $700 for a source repair like flashing around a vent pipe, a valley repair, or a small shingle section replacement. If the decking under the shingles is rotted, that’s an additional cost we show you before we cut anything.
Valley and Flashing Leak Repair
Valleys are the most common leak point we find on Commerce’s 1950s through 1970s tract homes. These roofs were built with shallow pitch and aging valley metal that corrodes and separates. We repair valleys with new flashing or install ice and water shield underlayment in the valley, which solves the leak at its source instead of caulking over it.
Vent Boot and Pipe Jack Repair
Vent boots crack from the same heat aging that wrecks Commerce shingles. A cracked boot lets water run right down the pipe and into the attic. Replacing a vent boot and pipe jack is usually a $250 – $450 fix, and it’s one of the highest-value repairs we do because it stops attic moisture before it rots insulation and decking.
Trusted Brands We Service in Commerce
We work with your roof’s brand, not ours. Since Commerce’s housing stock spans multiple decades and the commercial roofs use various membrane systems, we’re certified across seven major shingle manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Commerce homeowners, we most often match IKO and Atlas shingles on the older tract homes, and Tamko or Boral for homeowners who want a specific performance tier. We carry or can source matching materials quickly, so a repair blends with the existing roof rather than looking like a scar. Seven brands, one standard of installation. If your roof has a warranty that’s still active, we’ll check the manufacturer’s repair guidelines before touching anything.

AfterCommon Roof Repair Problems We See in Commerce Homes
- Oxidized shingles on 1950s – 70s tract homes. Commerce doesn’t get heavy storms, but it gets months of direct inland sun that bakes asphalt shingles until they’re brittle. We regularly find granule loss and cracking that exposes the underlayment and lets water through during even light rain.
- Clogged flat-roof drains and scuppers from diesel soot. The constant truck and rail traffic along the 5/710 corridor deposits a greasy grit layer that water carries into drains. Once a drain clogs, water ponds, and a small seam leak becomes a structural problem over time.
- Rodent and heat damage in attics. Commerce’s older homes have attics that get extremely hot, and the venting wasn’t designed for current conditions. We find rodent-chewed wiring and damaged insulation when we open roofs and decking near the rail-adjacent streets.
- Undersized framing and rotten decking discovered mid-repair. When we open a roof on a 1960s Commerce home, we sometimes find decking that’s been slowly failing under heat cycling. We won’t just nail new shingles over it; we’ll show you what we found and price the decking replacement before moving forward.
Pricing for Roof Repair in Commerce, CA
Most roof repairs in Commerce land between $350 and $900 for residential shingle work and $600 to $1,400 for flat commercial membrane repairs. Shingle replacement on a small section runs $350 – $550, flashing and valley repairs run $400 – $700, and a full vent boot replacement is typically $250 – $450. The biggest cost variable on Commerce’s older homes is what we find under the shingles: rotted decking, rodent damage, or outdated wiring that code requires us to address once the roof is open. We handle that with transparent allowances written into the contract, and any surprise is priced and approved in writing before we touch it. Call (866) 650-8319 for a free estimate with line-item pricing.

FAQs About Roof Repair in Commerce
In most cases we see in Commerce, the leak keeps coming back because the real problem is drainage, not the membrane. Diesel soot and grit from truck and rail traffic along the 5 and 710 clog the drains and scuppers, water ponds, and each new pond finds the next weak seam. A patch over a ponding area fails. We clear the drainage first, identify where water actually sits, and only then patch the membrane, so the repair holds. Call (866) 650-8319 if you’re tired of re-patching the same spot.
Expect us to open the affected area and tell you exactly what’s under the shingles before we quote anything beyond the original scope. On a recent low-slope roof near Washington Blvd and Atlantic Ave in Commerce, we found a leak near a valley, and under the decking we discovered rodent-chewed wiring running through the attic and undersized framing that had sagged. We replaced the decking, upgraded the underlayment, installed new flashing, and brought the wiring to code. Every additional item was priced and approved in writing before we touched it. That’s how we handle every Commerce repair.
When a repair in Commerce is large enough to require a permit, the permit itself adds a few hundred dollars, but the bigger cost variable is what the inspection triggers. On older Commerce homes, opening a roof can expose outdated wiring or undersized framing that current code requires us to correct before we close the roof back up. We handle this by writing allowances into the contract up front and getting written approval for any code-mandated work before we do it. You’ll never get a surprise invoice from us.
Yes. We handle shingle and low-slope residential roofs on the 1950s – 70s tract homes and TPO, EPDM, and modified-bitumen flat roofs on Commerce’s warehouses and machine shops. That dual capability matters in this city because many properties are mixed-use or have residential and commercial structures on the same lot. One company, one inspection, one conversation. Call (866) 650-8319 and we’ll schedule a time to look at both.
Heat aging is the number one killer of rooftops in Commerce, not storms. We address it by replacing oxidized shingles with materials rated for inland sun exposure, checking attic ventilation while we’re on the roof, and recommending reflective coatings or lighter membrane options for flat commercial roofs that sit under full sun with no shade. The fix isn’t just replacing what’s worn out; it’s making sure the new material can take the same heat without failing in five years.
If you’ve got a leak, missing shingles, or a flat roof that keeps ponding in Commerce, call us at (866) 650-8319 to schedule a free inspection and estimate. We’ll tell you what’s wrong, what it costs to fix, and whether you actually need a repair or something more. That’s the job.
