Fast, Reliable Roof Repair Across Lennox
Roof repair in Lennox usually comes down to one of two things: a low-slope roof that’s been baked by the LA Basin sun until the membrane cracked, or a storm that found every weak seam on a 1950s fourplex. Most Lennox residents reach us through a landlord or property manager who’s chasing a leak, and they want the opening priced before the work starts. Our crews know the tight lot lines along 104th Street, the dense rental blocks north of Lennox Boulevard, and the particular way airport soot settles on every roof in ZIP 90304. Call (866) 974-2271 and we’ll get your roof assessed, quoted, and on the schedule.
Why Koreatown Roofing Is Lennox’s Preferred Roof Repair Company
We’re a roofing-only contractor. That distinction matters in Lennox, where most of the housing stock is mid-century stucco over wood frame, and a generalist who’s never opened an original sheathing deck can misprice the job badly. Our crews work on flat roofs, low-slope roofs, metal roofs, and the occasional shingle gable over a converted garage. We don’t hand your roof to a rotating subcontractor. The crew that inspects your Lennox property is the crew that repairs it.
Lennox is unlike any city around it. Hawthorne and Inglewood have city building departments. Lennox doesn’t. Everything permit-related runs through LA County Building & Safety, and the inspectors there look at roofs differently. They ask questions about ventilation, sheathing condition, and valley protection that neighboring jurisdictions might not raise. That’s not a headache for us. It’s a local reality we plan for, and it’s why landlords in Lennox call us back when the next fourplex needs work.
Manny Cordero leads the company with a simple standard: every quote is written for the roof we’ll actually find when we open it, not the roof the landlord hopes is there. That honesty has kept our schedule full across Lennox, from the apartment blocks near Hawthorne Boulevard to the older rentals south toward El Segundo.
Styles & brands we work with






Storm Damage Roof Repair in Lennox
Storm Damage Roof Repair in Lennox typically means water got in during one of the winter storms that sweep across the basin and drop heavy rain on roofs that haven’t seen moisture in months. On shingle roofs, wind tears loose shingles and exposes underlayment. On flat and low-slope roofs, the real damage is usually ponding water that sat for 48 hours over a cracked seam and migrated under the membrane. By the time a tenant reports a ceiling stain, the roof has been leaking for weeks.
For Lennox, we price storm repairs by the actual area opened, not a flat guess. Minor shingle replacement runs $380 to $750 for a typical Lennox bungalow roof edge. A larger low-slope patch with new membrane, sealant around penetrations, and fasteners runs $850 to $1,600. When water has traveled, the tear-off area grows and the quote is revised in writing before we remove more material. That’s how a storm repair stays honest.
Low-Slope Ponding Repairs
Ponding water on a Lennox flat roof is rarely a drainage pitch problem. It’s usually a sag in the substrate from years of sun-softened membrane over original 1950s construction. We find the low spot, open it, and inspect the decking beneath before quoting the fix.
Wind and Debris Damage
Strong winds off the LAX flight path carry grit and debris that scours roof surfaces over time. Shingles that survived the heat often fail at the edges after a wind event. We replace loose shingles, reseal flashing, and document everything for insurance when Lennox landlords need it.
Metal Roof Repair in Lennox
Metal Roof Repair in Lennox is less common than membrane work, but it shows up on the small wave of retrofitted rental units and the occasional owner-occupied home that invested in a standing-seam panel system. The failure mode here isn’t the metal itself. It’s the fasteners and sealant at the panel seams. Heat expansion and contraction in the LA Basin sun works fasteners loose over a decade, and once a grommet fails, water tracks along the seam and drips inside far from the actual entry point.
We repair metal roofs on Lennox properties by locating the exact seam or penetration failure, resealing with manufacturer-appropriate sealant, replacing failed fasteners, and checking every lap joint in the field. Panel replacement for localized hail or impact damage runs $400 to $900 per damaged panel. A full seam reseal on a small Lennox duplex roof runs $1,200 to $2,200 depending on roof height and access. We don’t stage on a neighbor’s roof. Tight Lennox lots mean our crews often work from the rear alley or the street, and that access constraint is built into the quote.
Seam and Fastener Reseal
Most Lennox metal roof leaks are fixable without panel replacement. We clean the seam, reapply the correct sealant, and torque or replace fasteners. It’s detail work that takes a half day on a typical duplex.
Flashing and Boot Replacement
Metal roofs around Lennox still use rubber vent boots and pipe collars that dry out like anything else. We replace boots, reseal pipe penetrations, and reflash the base with material matched to the existing roof. It’s often the cheapest thing on the estimate and the most common actual leak source.
Trusted Brands We Service in Lennox
Your roof, your material choice. We work with the brands you already trust, including GAF, CertainTeed, and Owens Corning, which means a Lennox landlord isn’t stuck with whatever single brand a contractor happens to have in the yard. We stock local parts for Lennox customers, from GAF underlayment and drip edge to CertainTeed shingle bundles and Owens Corning ridge products, so a standard repair doesn’t wait on a distributor run across the county. If your roof carries a specific manufacturer’s shingle or membrane, we match it. If you’re deciding between brands for a larger repair, Manny will walk you through the performance and price differences without pushing one line because it’s convenient for us.

AfterCommon Roof Repair Problems We See in Lennox Homes
- Membrane cracking on flat and low-slope roofs. Intense UV and long dry spells bake the surface until it splits, usually around pipe penetrations or roof drains. Once water gets under the membrane, it travels before it shows up on a ceiling.
- Hidden decking rot under original sheathing. On a 1950s fourplex near 104th Street and Firmona Avenue, we opened a shallow-pitch roof and found the original sheathing delaminating under failed underlayment, with no ice and water shield in the valleys. The landlord got photos, a written price, and an approved change order before we replaced the decking.
- Dried-out sealant around vents and flashings. The sun beats down on every roof penetration in ZIP 90304 and the sealant shrinks. We replace boots and reseal the base, which stops the leak before it moves inside the wall.
- Ventilation and sheathing corrections triggered by LA County inspection. When a repair opens the roof, an LA County Building & Safety inspector may flag missing ridge vent or soffit ventilation. We plan for that contingency in the quote instead of treating it as a surprise.
Pricing for Roof Repair in Lennox, CA
Roof repair in Lennox runs from a few hundred dollars to several thousand depending on what’s actually under the surface. A simple vent boot replacement is $150 to $300. Shingle replacement around a leaky valley runs $450 to $900. Low-slope membrane patches run $850 to $1,600. Full decking replacement on an opened section of a 1940s fourplex can add $1,800 to $4,000, and that’s the number that changes most Lennox quotes once our inspection finds what the roof has been hiding. We write quotes with allowances for exactly this, and every change is priced and approved in writing before we touch extra material. Call (866) 974-2271 to schedule a free estimate.

FAQs About Roof Repair in Lennox
Yes, most roof repair work in unincorporated Lennox requires a permit through LA County Building & Safety rather than a city hall, and that permit often triggers code corrections when the repair opens the roof. The inspector may require sheathing upgrades, ventilation improvements, or valley protection that wasn’t present on the original 1940s or 1950s construction. That’s not a surprise we fear. It’s a line item we estimate for. Call (866) 974-2271 for an exact quote on your building.
We document it, price it, and get written landlord approval before replacing anything beyond the original scope. The original sheathing on Lennox fourplexes was never protected by ice and water shield, and decades of sun and occasional storm water leave it delaminated more often than not. Our quotes include a decking allowance so the first number you see already anticipates the most likely hidden condition.
Yes. Tight Lennox lot lines and shared property lines mean roofers can’t always set up where the material is. Our crews access metal roofs from the street, the rear alley, or the roof edge where the parapet allows. We factor access into the estimate so you aren’t hit with a field change when the crew arrives and realizes the neighbor’s roof is off-limits.
Flat and low-slope roofs in Lennox fail by membrane cracking, ponding, and dried-out sealant rather than the wind and freeze damage you see on shingle roofs in other climates. The sun bakes the surface for months at a time, airport soot from LAX settles into every seam, and when a winter storm finally dumps rain, the water finds every dried-out penetration at once. Shingle roofs shed water, but a membrane roof has to hold it back, and that’s a different game.
You compare them by the allowances and the assumptions. A low bid that prices only visible damage will climb once the decking is exposed, and in Lennox, the decking is almost always part of the story. Ask each contractor what their quote assumes about sheathing condition, whether the LA County ventilation correction is included, and how they handle a change order when the roof is worse than expected. Then compare the real numbers, not the headline.
