Fast, Reliable Roof Repair Across Commerce
Roof repair in Commerce, CA usually costs between $350 and $1,400 for the most common residential fixes, with full underlayment and decking work on older 1950s-70s homes running higher. You can reach us at (866) 321-6172 for a free estimate, and we’ll send a crew that actually knows Commerce’s specific roof failures. The city splits into two roofing worlds: modest tract homes near the 5 and 710 interchange, and sprawling tilt-up warehouses along the rail corridor. Most residential calls start as a small leak. Then we open the decking and find what 60 years of dry-season cracking and winter rain have actually done.
We work in Commerce neighborhoods like the residential blocks around Bandini Boulevard and the streets fanning out from the Commerce Casino toward the Citadel Outlets. Our team has patched shingle roofs on 1950s ranch homes two blocks from the Santa Ana Freeway and replaced rotted decking on houses where freight train soot has been settling on shingles for decades. The Roof Repair work here is never cookie-cutter. We inspect first, then tell you what the roof actually needs.
Why Van Nuys Roofing Co Is Commerce’s Preferred Roof Repair Company
We don’t stock a single product line and push it on every house. That matters in Commerce because the residential roof stock is old, varied, and often built with materials you can’t just swap for whatever’s in the warehouse. Some homes have original wood shake remnants under later asphalt layers. Others have low-slope built-up roofs with gravel that’s long since washed into the gutters. Our crews are experienced with GAF, CertainTeed, and Tamko systems, among others, so when we repair a Commerce roof we match what’s actually there or tell you honestly why it’s time to move to a different product.
Rick Dominguez runs our crew with one rule: an inspection happens before any repair recommendation. In Commerce, that matters because the first leak you see is rarely the whole story. We’ve found valley rot, undersized drip edges, failed pipe boots, and decking that crumbles when you pull the shingles back. We document what we find, price the fix in writing, and you approve it before we start. No one likes surprises. We avoid them by looking before we quote.

Storm Damage Roof Repair in Commerce
Storm damage roof repair in Commerce often isn’t what homeowners expect. The city gets little actual hail and few high-wind events, but the first real December storm after a long dry season is when dozens of roofs start leaking at once. The sequence is predictable: summer UV bakes shingles and membranes, microscopic cracks open at flashings and seams, and then rain pushes through. By the time a homeowner sees a ceiling stain, water has usually been migrating under the roof surface for a week. Our storm damage calls in Commerce begin with a full inspection of flashings, scuppers, valleys, and penetrations, not just the stained area.
Winter Leak Response
Most Commerce storm damage we see is leak-driven, not wind-driven. Shingles near rail-adjacent blocks carry a layer of black soot that hides granule loss until a heavy rain reveals the bald spots. We prioritize wet-weather repairs on homes in Commerce’s residential pockets near the 710, where pooling at low-slope sections sends water sideways into walls instead of down. A typical storm-related flashing or vent boot repair runs $350 to $700. More involved valley or underlayment work lands between $800 and $1,400 depending on how much soaked decking has to come out.
Flat and Low-Slope Storm Failures
Commerce’s warehouse and industrial properties fail differently. TPO and modified-bitumen roofs develop ponding at clogged scuppers after rail soot and rubber dust block drainage. The first storm fills the pond, and the membrane, already brittle from heat, cracks at the seam. We repair these with heat-welded patches and correct the drainage so the next storm doesn’t repeat the failure. If you think a warehouse roof is “just a membrane issue,” call us. We’ll tell you whether it’s a $600 patch or a re-roof you should plan for. Call (866) 321-6172 and we’ll give you a straight answer.
Metal Roof Repair in Commerce
Metal roof repair in Commerce covers two very different buildings: the standing-seam and corrugated metal roofs on industrial and warehouse structures, and the occasional older residential metal roof or patio cover. On industrial buildings near the rail yards and along the industrial stretch east of the 5, we see a lot of fastener failure. Decades of thermal movement plus occasional train vibration loosen screws and neoprene washers, and the roof starts leaking at the fasteners before any metal panel actually fails. Resealing and replacing fasteners on a Commerce warehouse typically runs $500 to $1,800 depending on access and panel condition.
Residential Metal Repairs
On the residential side, Commerce homes occasionally have metal patio roofs or carport covers that leak at the flashing where metal meets the main shingle roof. These are usually simple fixes: new closure strips, resealed laps, or replaced transition flashing. Expect $400 to $900 for a typical patio roof repair in Commerce. We also see older galvanized valley metal that’s rusted through on 1950s and 60s homes. That’s a removal-and-replace job, and we price it before touching it.
Commercial Panel Replacement
When a metal panel itself is damaged or rusted through on a Commerce warehouse, we don’t slather it with sealant and call it fixed. We cut out the damaged section and install a matching profile panel with new fasteners and butyl tape at the laps. For buildings near the Citadel Outlets or along the rail spur, we also check drainage and debris loading before quoting, because a leaking metal roof in that area is usually leaking because the scuppers are blocked with freight dust and rubber particles. That’s a Commerce-specific problem we’ve seen more times than we can count.
Trusted Brands We Service in Commerce
We repair roofs built with GAF, CertainTeed, Tamko, Boral, IKO, Atlas, and Owens Corning products. Seven leading brands, one crew that knows them all. That matters for Commerce homeowners and industrial property managers because we don’t steer you toward the one product we happen to buy in bulk. If your roof has CertainTeed shingles, we match them. If your warehouse has a Boral tile roof transition, we know the profile. Manufacturer warranty eligibility is something we can discuss on any repair, and we’re happy to explain what your existing product’s warranty actually covers. In Commerce, where so many buildings mix materials from different decades, this multi-brand fluency means fewer wrong repairs.
Common Roof Repair Problems We See in Commerce Homes
- Failed original underlayment on 1950s-70s roofs: The felt underlayment installed on Commerce tract homes in the Kennedy and Nixon years is now powder in many spots. The first winter rain after a dry season finds those gaps, and a ceiling stain appears days later. We usually discover rotted decking beneath these old layers once shingles come off.
- Rotted valley decking and undersized drip edges: Older Commerce homes near the 5 often have 1×6 skip sheathing at the valleys. Debris from nearby truck traffic and wind-blown soot collects in the valleys, holds moisture, and rots the wood. We replace the decking and add ice and water shield before re-shingling, because the original drip edge is frequently too short to protect the fascia.
- Ponding on flat and low-slope sections: Homes in Commerce’s southern tracts and many industrial buildings have roofs with very little pitch. Scuppers and drains clog with rail dust and rubber ash, water ponds, and the membrane cracks in the heat. By the time a leak shows inside, the insulation board beneath the membrane is often soaked and needs replacement.
- Soot and rubber debris accumulation: Commerce’s freight-adjacent location means roofs collect black soot and fine rubber particles from truck and rail traffic. This debris masks shingle wear, accelerates granule loss, and clogs drainage. We see it on homes from Bandini Boulevard to the residential blocks east of the Commerce Casino.

Hidden Damage Handling on Commerce Roofs
The biggest reason a Commerce roof repair quote moves from $700 to $2,000 is what’s under the shingles. On a 1962 tract home near the Citadel Outlets, a homeowner called us after a ceiling stain appeared following the first December rain. We pulled the architectural shingles and found the original 1×6 skip sheathing rotted through at the valleys and the drip edge undersized. We replaced the decking, added ice and water shield in the valleys, and installed new starter strip and ridge vent before re-shingling. The homeowner approved the added decking cost in writing before we nailed a single square. That’s how we work in Commerce: inspection first, visible documentation, written approval.
This matters because Commerce’s mix of 1950s-70s tract homes and tilt-up warehouses means roof repair often starts as a leak call but turns into opening up original decking and discovering 60-year-old underlayment and substandard flashing details. It’s a problem you don’t see as often in newer-built cities like Downey or Paramount. When we give you a roof repair quote, we include allowances for what we expect to find based on the home’s age and architectural style. If the surprise is bigger, you see it before we fix it.

FAQs About Roof Repair in Commerce
We inspect first and write allowances into the contract for what we expect to find on a roof of your home’s age. Before any repair begins, we open a small area of decking to assess what’s beneath. If we find outdated wiring runs, undersized framing, or rotted decking, we document it, price the correction in writing, and you approve it before we proceed. Nothing gets nailed down without your sign-off. Call (866) 321-6172 to schedule an inspection, and you’ll know exactly what your roof holds before spending a dollar on repairs.
The most common storm damage in Commerce is leak-through at valleys and flashings where dry-season cracks open up. The long inland heat bakes shingles and membranes, microscopic seams split, and the first real December rain pushes through. We also see scuppers clogged with rail soot and rubber dust causing ponding on flat sections. A typical storm repair costs $350 to $1,400, and we’ll confirm the full scope before we start. Call (866) 321-6172 for an exact quote.
Yes. We repair standing-seam and corrugated metal roofs on warehouses and industrial buildings throughout Commerce, including those near the rail yards and the Citadel Outlets. Fastener failure, rusted panels, and flashing problems at parapets and curbs are the most common issues we see. Typical metal roof repairs on Commerce industrial buildings run $500 to $1,800. We’ll inspect, document what’s failed, and give you a written price. Call (866) 321-6172 to set up an assessment.
Ask for the inspection report. A legitimate repair-versus-replace recommendation should include photos, moisture readings, and the condition of the decking and underlayment. We provide all three. In Commerce, many older roofs do need replacement, but some contractors default to replacement because it’s a bigger ticket. If a quote says “full replacement” without opening the roof and showing you the evidence, get a second opinion. Our inspection-first approach gives you the documentation to make that call yourself. Call (866) 321-6172 for an honest assessment.
