Fast, Reliable Roof Replacement Across Lennox
Roof replacement in Lennox, CA typically runs $11,000 to $24,000 for a full tear-off on a single-story stucco home, and most jobs take 3 to 6 working days once permits clear. That’s the honest range for this corner of LA County, where short, low-slope roofs and packed lot lines shape the job more than most homeowners expect. We know Lennox because we work here: the fourplexes off 104th Street, the duplexes behind Lennox Park, the aging diagonal sheathing under shingles that haven’t been touched since the 1960s. Call (866) 974-2271 and we’ll come measure a roof in Lennox, free.
Why Koreatown Roofing Is Lennox’s Preferred Roof Replacement Company
Most roofing contractors treat Lennox as a drive-through on the way to a bigger job in Torrance or Culver City. We don’t. Our crews work 90304 regularly, and we know what a Lennox roof looks like from the underside: original 1×6 board sheathing, shallow attic cavities with almost no ventilation, and membrane edges that have been sealant-patched so many times the original fasteners are hidden under three layers of old patchwork.
We’re roofing specialists, not generalists. Roof replacement is one of only three services we perform, alongside roof inspection and roof repair. That focus means when we scope a replacement in Lennox, we’re looking at the full lifecycle of the roof, not just the shingle layer. Manny Cordero leads our crews, and he’s walked enough Lennox fourplexes to know that what’s under the roof matters as much as what goes on top. Our reputation in neighborhoods like this comes from doing the job right the first time, on schedule, without surprise change orders.
Styles & brands we work with
New Roof Installation in Lennox
New roof installation in Lennox usually means one of two things: a full tear-off and re-roof on an existing 1940s-to-1960s home, or a roof going on new construction, which in Lennox mostly means an ADU or a small infill unit where the lot was split decades ago. A full new roof installation on a Lennox bungalow runs $12,000 to $22,000, depending on square count and how much decking has to be replaced once we open it up. On new construction, the price starts closer to $9,000 for a simple single-story accessory structure and climbs from there.
Here’s the thing about new roof installation in Lennox: the permit goes through LA County Building & Safety, not a city hall. There is no Lennox city planning counter. The county reviews structural, fire, and drainage compliance, and the process takes as long as it takes. We handle the permit package and inspection coordination as part of the job, so you’re not driving plans to Alhambra or wherever the county’s reviewer happens to be that week.
What Gets Replaced Under a New Roof
On most Lennox homes we open up, the old roof is 2 to 3 layers deep. The shingle you see from the street is only the top layer; beneath it sits the original 1960s felt, maybe an old built-up membrane, and whatever the last homeowner’s handyman nailed over it. New roof installation means stripping all of it to bare sheathing, inspecting every board, and replacing any pieces that have rotted along the eaves or around unflashed pipe penetrations.
We also correct what the original builder skipped: drip edge at the eave and rake, proper valley metal, and step flashing where the roof meets stucco walls. On Lennox’s low-slope and shallow-pitch stock, we often add peel-and-stick membrane at the eaves and in valleys before the new shingles go on, because the real failure point on these roofs is the transition, not the field.
Why We Scope the Decking Before We Quote
On a Lennox roof, the decking is the variable that changes a bid the most. Original diagonal board sheathing from the 1940s and 1950s is often dry and cracked along the nail lines, and any old leak that ponded for a season leaves soft spots that no shingle can fix. We walk the roof and check it from inside the attic before giving you a written price, so the number you see includes what we expect to find, not what we hope you won’t ask about later.
Reroofing in Lennox
Reroofing in Lennox is the more common path: stripping the existing shingle or membrane system and installing a new roof over the existing structure, without changing the roofline. For Lennox’s dense rental stock, reroofing is landlord-driven, and it’s usually triggered by a failed low-slope membrane, active leaks into a unit below, or a buyer’s inspection report. A typical Lennox reroof runs $11,000 to $18,000 on a single-story bungalow or duplex, and $18,000 to $26,000 on a fourplex, depending on the square count and the condition of the decking underneath.
Reroofing here almost always touches more than the shingles. The original decking on most of these homes is 1x boards, not plywood. When we tear off and find cracked boards or rotted sections around old vents, those boards get replaced. That’s decking work, and it’s priced per sheet or per board foot in our quote. If the roof is low-slope, we’re not re-shingling it at all; we’re installing a membrane system that’s built to shed water on a shallow pitch, typically with tapered insulation to fix ponding areas.
When a Roof Is Past Repair
Some Lennox homeowners ask us to patch a roof that’s been patched four times already, and we’ll tell you when that’s money down a hole. If the membrane is cracked through in multiple places, the sealant around penetrations has dried and split, and the decking has soft spots, a reroof costs less than three more years of chasing leaks. We’ll show you photos from our inspection, not a sales pitch.
What Gets Installed on a Lennox Reroof
On shallow-pitch and low-slope sections, we install a self-adhered or hot-mopped membrane system rather than shingles, because shingles don’t shed water on a pitch below about 3:12. On the steeper gable ends of the same roof, we’ll install architectural shingles from a brand you already know: GAF, CertainTeed, Owens Corning, IKO, among others. Your roof, your material choice. We don’t steer you to one brand because it’s the only one in our warehouse; we work with seven manufacturers and pick what fits the roof and the budget.
Trusted Brands We Service in Lennox
We work with the brands you already trust: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That’s a broader manufacturer roster than you’ll find from most single-truck roofing companies in LA County. What does it mean for a Lennox homeowner? It means we recommend a shingle or membrane because it fits your roof’s pitch, your budget, and your building’s design, not because we have a supplier contract that dictates what we sell. We keep common profiles and colors for these brands stocked for Lennox jobs, and if a specific color has a longer lead time, we tell you that before the quote, not after you sign.

AfterCommon Roof Replacement Problems We See in Lennox Homes
- Ponding on low-slope membranes. Lennox’s flat and low-slope roofs hold water after storms, and that standing water eats through dried-out sealant faster than any winter freeze ever could. By the time the tenant on the top unit sees a ceiling stain, the membrane has been cracked out for months.
- Soot and grit from LAX and the freeways. Airborne particulate from the airport approach path and the 405 settles into shallow-pitch roof fields and wears granules off shingles faster than you’d see in the Valley. We see original 1960s shingles down to bare mat in Lennox more often than in any neighboring city.
- Rotted decking under old patches. The original diagonal board sheathing on these 1940s-to-1960s homes soaks up leak water for years before anyone notices. When we tear off, we routinely find boards that look fine from the attic but crumble at the nail line once the old roof comes off.
- Staging nightmares on tight lot lines. Fourplexes on 104th Street and nearby blocks sit shoulder to shoulder with maybe two feet of side yard on each side. If the roof is two stories up and the only access is over a neighbor’s roof, the job has to be planned around that, not figured out on day one.

FAQs About Roof Replacement in Lennox
Through the county. Lennox is unincorporated, so roof replacement permits run through LA County Building & Safety, not a city hall. There is no Lennox municipal building department. We pull the permit, schedule the inspections, and handle the paperwork as part of every replacement we do here.
Because the homes were built between the 1940s and 1960s with 1x board sheathing, and decades of small leaks, poor attic ventilation, and ponding water on the low-slope sections have rotted the boards before the shingles wore out. We inspect the decking from the attic and the roof surface before we quote, so decking replacement is in the price up front, not added later as a surprise.
We plan access before the tear-off starts. On a Lennox fourplex, the dumpster often has to go in a shared driveway, and our roof access may run over a neighbor’s roofline. We knock on that neighbor’s door, explain the job, and get written access permission before we set a ladder. That’s not something a crew figures out the morning of. Call (866) 974-2271 and we’ll walk the site and scope staging before you sign anything.
On pitches below about 3:12, which covers much of Lennox’s rental stock, shingles don’t shed water reliably, so we install a membrane system: self-adhered or hot-mopped, often with tapered insulation to fix ponding. On the steeper gable ends of the same building, architectural shingles from GAF, CertainTeed, Owens Corning, or IKO work well. The right system depends on the actual pitch, not the seller’s preference.
Look at the line items, not the bottom number. Ask whether the price includes county permit fees, dumpster and haul-off, decking replacement, new drip edge, and valley metal. Ask whether the membrane system on the low-slope section is actually spec’d, or just described as “roofing” with a note to figure it out later. And ask whether the company pulls the permit or makes you pull it. We include every one of those line items in writing. Call (866) 974-2271 for a free estimate that you can compare line by line against any other bid.
