Fast, Reliable Roof Repair Across Commerce
Roof repair in Commerce, CA usually runs $350 – $1,400 for a focused fix like a flashing replacement or leak patch, and most single-issue repairs are done in one day. The catch is that this city’s older housing stock hides rot and outdated waterproofing behind small stains, so the repair quote often moves once we open the roof and see what’s actually underneath. We are Sunridge Roof Repair, a roofing-only company led by Ruben Ochoa, and we inspect before we recommend, so you will know exactly what you are paying for and why. Call (833) 589-5180 any time to schedule a free estimate for Roof Repair in the 90101.
We work in Commerce regularly, from the stucco tract homes west of the industrial core to the flat-roof warehouses near the 5/710 interchange. The roof assemblies here split sharply: low-slope and near-flat residential work dominates over steep shingle work, and the adjacent industrial buildings have their own failure patterns. That is exactly the kind of local knowledge that keeps a Commerce estimate honest.
Why Sunridge Roof Repair Is Commerce’s Preferred Roof Repair Company
Homeowners in Commerce call us after seeing a ceiling stain or hearing a drip in the garage, and they usually want one thing first: an honest read on whether the roof can be repaired or needs replacement. We give that read without a sales push. Our crews are roofing only. No siding, no gutters, no windows to upsell. That focus means every crew member knows low-slope flashing, flat-roof seams, and the peculiar way 1950s stucco homes fail at wall transitions.
Ruben Ochoa built Sunridge around the diagnostic step most contractors skip. A roof inspection is a standalone service with us, not a hook to sell a new roof. When Commerce homeowners call about a leak near the porch or garage tie-in, we trace the water path before touching the shingles. That approach earns repeat calls and referrals, and it is why homeowners in Commerce book our crews for both emergency patches and full replacements.

Storm Damage Roof Repair in Commerce
Storm Damage Roof Repair in Commerce deals with what the winter rain season leaves behind: lifted shingles, torn flashing, and ponding that pushed water under the membrane on low-slope roofs. A typical storm-related repair in Commerce runs $420 – $1,200 depending on whether we are re-sealing a seam, replacing a section of decking, or re-flashing a wall transition. If the damage is localized to one slope or one penetration, we can usually get it done the same afternoon. We match your existing material when possible and always quote the repair line item by line item.
What We Look For After a Storm
We check the roof field first, but on Commerce’s 1950s-60s stucco homes the weak point is almost always the wall-to-roof transition. The original cut-back flashing dries out and cracks over decades, and the first real storm pushes water behind the stucco. We also inspect drains and scuppers on near-flat roofs, because ponding against a wall line can rot the decking long before the ceiling stains.
Storm Damage on Low-Slope Roofs
Low-slope and near-flat roofs in Commerce take storm damage differently than steep shingle roofs. Where a pitched roof sheds water, a low-slope roof holds it, so failed seams and cracked flashing become immediate leaks. We inspect every penetration, seam, and drain point after a storm, not just the spot where the water showed up inside.
Metal Roof Repair in Commerce
Metal Roof Repair in Commerce usually involves re-sealing fasteners and panel seams on the standing-seam or metal-panel roofs found on some mid-century additions and porch covers. A fastener re-torque and seam re-seal typically costs $300 – $750. If the metal is corroded through at the eave or a panel needs section replacement, the repair can run $850 – $1,400 depending on the gauge and finish. Commerce’s dry heat and low rain mean most metal failures here are from UV-expansion cycling rather than rust, but the occasional corroded fastener line near the 710 corridor still shows up.
Seam and Fastener Re-Sealing
Metal expands and contracts hard in the inland Los Angeles Basin heat, and over time that movement backs out fasteners and opens seams at ridge caps and wall transitions. We re-torque the fastener field and apply a compatible sealant at every seam and penetration. This is a same-day job on most single-story Commerce homes.
Section Replacement and Matching
When a metal roof panel is too far gone for a patch, we cut back to the nearest lap joint and replace the full panel or a clean section. We source through our established supply chain across GAF, CertainTeed, Owens Corning, IKO, and Atlas, so matching a metal roof or replacing metal components on a porch cover is handled without ordering delays.
Trusted Brands We Service in Commerce
We are not tied to one manufacturer. Sunridge Roof Repair is brand-agnostic and works with seven major roofing product lines, including CertainTeed, Owens Corning, IKO, and Atlas, plus premium and value tiers across GAF, Tamko, and Boral. When we repair a Commerce roof, we pull materials that match what is already up there or upgrade only where it actually makes a difference. For most Commerce homeowners, that means matching an existing architectural shingle or selecting a membrane that plays well with the original felt and flashing rather than pushing a full re-cover. We keep local parts availability in mind and will tell you honestly if a repair is the right call or if replacement genuinely costs you less over the next ten years.
Common Roof Repair Problems We See in Commerce Homes
The roofs in Commerce fail in predictable ways, mostly because of age and the city’s particular heat patterns. Here is what we see most.
- Dried-out cut-back flashing at wall transitions. The 1950s-60s stucco tract houses west of the industrial core used tar-paper flashing at low-slope porch and garage tie-ins. That material dries, cracks, and lets water wick behind the stucco, rotting the fascia before any interior stain shows.
- Split modified bitumen seams on near-flat roofs. Summer heat cycling opens seams on aging flat and low-slope assemblies, and a small split becomes a wide-open path to the decking by December. We see this constantly on original or second-covering roofs in the 90101.
- Ponding at scuppers and failed drains. When the adjacent flat-roof structure holds water at the wall line, it pushes under the underlayment and softens the decking. The homeowner only sees a ceiling stain long after the deck is damaged.
- Rotted fascia behind the drip edge. Our crews find soft 1×6 fascia on older Commerce homes where water wicked behind the drip edge for years. A repair that starts as a shingle replacement often includes fascia replacement once we open the wall.

AfterPricing for Roof Repair in Commerce, CA
What you pay for roof repair in Commerce depends more on what we find when we open the assembly than on the size of the visible stain. A simple flashing re-seal runs $350 – $600. Leak repairs that require decking replacement, new ice and water shield, and re-flashing at a wall transition typically land between $850 – $1,400. Full low-slope porch re-covers with new membrane and edge metal start around $1,800 – $3,200. We write allowances into every contract for rot and outdated framing, so when we open your Commerce roof and find damaged wood or failed waterproofing, you get a written change order with the exact added cost before we do that work. No one approves surprise line items on a handshake. Call (833) 589-5180 for a free, itemized estimate.
The wildcard in every older Commerce home is what the original builders left you. Cut-back flashing, 15-pound felt, and nailed drip edge all reach end of life around the same decade, so a focused leak repair frequently reveals a bigger repair once the material is exposed. We price that day one, not after we are already on the hook.

FAQs About Roof Repair in Commerce
Because the original cut-back flashing on those 1950s-60s Commerce tract homes was never designed to last 60 years. When it dries out and cracks, water gets behind the stucco and rots the fascia and sometimes the top of the wall framing before you see a stain. The visible leak is the last symptom, not the first. We open the wall transition, assess what is still sound, and quote the repair before we build anything back. Call (833) 589-5180 to have us trace the actual water path, not just patch the shingles.
We write a rot allowance into the contract before work starts. Once we open the roof and expose the decking, fascia, and framing, we show you what we found and get written approval before any replacement work begins. We do not start a repair with an open-ended bill. On a 1950s stucco home off Saybrook Avenue, we found the original 15-pound felt disintegrated and the fascia soft where water had been wicking behind the drip edge. That job became a fascia replacement plus new ice and water shield at the wall transition, and the homeowner approved the added scope on paper before we proceeded.
Yes, most structural roof work in Commerce requires a building permit, and repairs that expose decking or framing often trigger code compliance checks for the original assembly. Commerce follows Los Angeles County building code, so opening a low-slope porch and finding outdated framing can require bringing the exposed section up to current nailing and drainage standards. We handle the permit paperwork for you and make sure the repair passes inspection, which is one more reason a Commerce-specific contractor beats a generalist who has never pulled a permit in this city.
Your residential low-slope roof and the flat roofs on Commerce’s rail-served warehouses near the 5/710 interchange share membranes but fail differently. Residential low-slope roofs leak first at wall transitions and porch tie-ins. Industrial flat roofs fail at seams, scuppers, and drain points after years of heat cycling. We work on both, but for your home, we are focused on the cut-back flashing, garage tie-ins, and UV-degraded seams that define Commerce’s 1950s-60s housing stock. The repair is the same principle: inspect, trace, quote, and fix what is actually damaged.
Yes. We source from seven major manufacturers including CertainTeed, Owens Corning, IKO, and Atlas, and we match the specific architectural shingle color and profile on your roof or confirm a close equivalent in writing before we start. On the Saybrook job, we re-covered the repaired section with matching architectural shingles after laying GAF StormGuard at the wall transition, so the patch disappears into the existing roof. Call (833) 589-5180 and we will give you a free estimate with the exact material match listed on the quote.
