Fast, Reliable Roof Replacement Across Lennox
Roof replacement in Lennox typically costs between $9,500 and $18,000 for a standard single-story bungalow, with most jobs finishing in three to five working days once the tear-off begins. That’s the honest range we quote, and it’s built around the reality of Lennox homes: tight lots, shared driveways, and LA County inspection schedules that dictate when we can lay underlayment and close up. Our crews know the 90304 streets, the stucco bungalows off Inglewood Avenue, and the fourplex layouts near Lennox Park. We’re Barnwood Roofing, and we’ve handled enough tear-offs under the LAX flight path to tell you straight what your roof actually needs. Call (855) 382-1073 and we’ll come look before you spend anything you don’t have to.

Why Barnwood Roofing Is Lennox’s Preferred Roof Replacement Company
We work differently than the replacement-only crews that knock on doors after every Santa Ana event. Barnwood Roofing does inspections, repairs, and replacements under one roof, which means when we tell you a full replacement is warranted, it’s because we already looked for the cheaper fix first. That’s the whole point: inspection first, recommendation second. Ruben Calloway built this company around that order of operations. He’d rather show you a repair that buys five more years than sell you a roof you don’t need yet. Lennox homeowners deal with enough noise from overhead; your roofing contractor shouldn’t add to it.
We’re based in Fontana, but our crews are in Lennox regularly and know the unincorporated LA County permit flow, the County inspection windows, and the narrow side yards that make tear-off logistics tricky here specifically. We pull LA County permits and schedule inspections so you’re never waiting on a sign-off we could have lined up two days earlier. Seven brands, one honest recommendation. We source from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we’ll match product to your home’s exposure and your budget, not to whatever’s sitting in a warehouse.

Flat Roof Replacement in Lennox
Flat Roof Replacement in Lennox focuses on the low-slope and near-flat built-up tar-and-gravel roofs that cover a large share of the 1940s-1960s fourplexes and apartment buildings in 90304. Many of these structures still carry their second-generation built-up roof, and by now the gravel is patchy, the flashing at parapet walls has UV-cracked, and water is finding its way in at plumbing penetrations. A flat roof replacement here typically runs $11,000 to $20,000 depending on square footage and how much decking has to be re-sheathed once the old roof comes off.
Tear-Off on Tight Lennox Lots
Flat roof work on a cramped fourplex lot means every step has to be choreographed. We stage materials in a single lane of the shared driveway, put tear-off debris in a low-profile dumpster positioned so a neighbor can still get out, and coordinate with County inspection stages so the new membrane goes down when it’s supposed to, not when it’s convenient. You shouldn’t have to think about any of that. That’s our job.
Built-Up Roof vs. Modern Membrane
When a Lennox flat roof has reached the end of its service life, we usually replace the old tar-and-gravel with a modern multi-layer system: new decking where the old skip-sheathing has delaminated, a tapered underlayment to correct drainage, and a durable membrane. We’ll show you the numbers for different product tiers side by side, so you can decide what fits.
Roof Installation in Lennox
Roof Installation in Lennox usually means a complete tear-off and re-roof on a single-story stucco bungalow where the original shingles from the 1950s or early 60s have been baked by decades of sun and lifted by Santa Ana winds. These homes were built with shallow-pitch roofs, and many still have the original 1x skip-sheathing underneath. The honest answer we give most Lennox homeowners: the old roof can’t simply be overlaid. The decking has to be inspected, and more often than not, sections have to be replaced before new underlayment goes down. A full roof installation on a typical Lennox bungalow runs $9,500 to $16,000.
Skip-Sheathing and Decking Replacement
On a 1950s stucco bungalow off a shared drive near the Inglewood edge of 90304, our crew pulled a second-generation built-up tar-and-gravel roof and found the original skip-sheathing had been patched with plywood scraps that had delaminated at two valleys and a plumbing penetration. We stopped, photographed the soft decking, priced the re-sheath and flashing rebuild in writing, and got the homeowner’s approval before laying new underlayment, then set GAF architectural shingles with a full starter strip and ridge vent to close it out for the County inspection. That’s how we handle every Lennox job: open it up, show you what’s there, get your sign-off in writing, and never touch what you haven’t approved.
New Construction and Full Roof Replacement
We also handle new construction roof installation on the occasional infill lot or ADU project in Lennox. The same brand-agnostic approach applies: we’ll match shingle type and underlayment spec to what the County plan checker requires, and we’ll keep the whole thing moving through inspection without you chasing a phone.

Trusted Brands We Service in Lennox
We install and service roofs from seven manufacturers, including GAF, CertainTeed, and Owens Corning. That breadth matters in Lennox because it means we recommend a product based on your home’s wind exposure, roof pitch, and budget, not because we have an exclusive deal with one factory. We keep a steady flow of common shingle colors and accessories stocked for quick turnaround on 90304 jobs, and we can order full manufacturer systems with the warranty registered in your name. The right material for your roof, not just what we stock.
Common Roof Replacement Problems We See in Lennox Homes
- Delaminated skip-sheathing under old built-up roofs. Most 1940s-1960s Lennox bungalows were framed with 1x skip-sheathing, and by the time the second-generation tar-and-gravel roof fails, that sheathing has rotted at valleys and plumbing penetrations. You can’t overlay it; you have to cut it out and re-sheath to pass County inspection.
- Santa Ana uplift at edge details on shallow-pitch roofs. Lennox roofs have just enough slope to shed rain but not enough to fight wind. Drip edge and starter strip that were never nailed to spec get lifted at ridge caps and rakes during Santa Ana events, and the damage compounds over the years.
- UV-cracked flashing at stucco parapet walls. The low-slung, party-wall-close rooflines common in Lennox put flashing directly against sun-baked stucco. Once that flashing cracks, winter rain finds the gap. County inspectors flag it the moment the tear-off is open, so it has to be addressed, not hidden.
- Shared driveway access for tear-off debris. A dumpster that blocks a neighbor’s car is the fastest way to turn a roof job into a dispute. We schedule debris removal around the narrow side yards and shared drives that define Lennox lots, and we keep the work area tight so life on the street doesn’t stop.

AfterPricing for Roof Replacement in Lennox, CA
A typical asphalt shingle roof replacement on a Lennox bungalow runs $9,500 to $18,000, and a flat roof replacement on a fourplex runs $11,000 to $20,000. The real driver on these older homes is what’s under the old roof: if the skip-sheathing has delaminated and needs full re-sheathing, that’s additional decking material and labor, generally $2,500 to $5,000 depending on square footage. Architectural shingles from GAF or CertainTeed run higher than basic three-tab, and a manufacturer-backed warranty adds cost but transfers if you sell. We write allowances into the contract for hidden decking and framing so the number you approve is the number we work to, and any surprise gets priced and approved in writing first. Call (855) 382-1073 for a free, written estimate.

FAQs About Roof Replacement in Lennox
LA County handles the permit. Lennox is unincorporated, so there’s no city building department to walk into. The permit runs through LA County Public Works building inspection, and final sign-off depends on County inspectors seeing the decking and underlayment at their scheduled stages. We pull the permit, schedule the inspections, and make sure the job is ready for every visit. If you want to know what a Lennox roof replacement will require on your specific home, call (855) 382-1073 and we’ll walk you through it.
Because the deck underneath is usually the problem. Most Lennox bungalows were framed with skip-sheathing, and by the time the old built-up roof fails, that sheathing has delaminated at valleys and penetrations. Laying new roofing over a rotted deck is how you get a warranty rejection and a County inspector red-tag. The honest path is a full tear-off, deck inspection, and re-sheath where needed. We’ll show you photos of what’s under there and price the fix in writing before any new material goes down. Call (855) 382-1073 to schedule that look.
We stage materials in a single lane of the shared driveway and position the debris dumpster so your neighbor can still get their car in and out. Our Lennox crews have worked enough of these lots to plan around the tight side yards and party-wall-close rooflines, and we’ll clear access with neighbors before the tear-off starts. It’s a small thing, but it keeps a roof job from turning into a block fight. Call (855) 382-1073 and we’ll talk through what your lot needs.
One square is 100 square feet of roof surface, and it’s the unit every roofer uses to price tear-off, decking, underlayment, and shingles. You should care because Lennox bungalows are small enough that a 1,200-square-foot home might have 14 to 16 squares, and every square of rotted decking you replace adds real cost. We’ll show you the square count and the per-square price on your estimate so you can check the math yourself. Call (855) 382-1073 for a written quote with the squares laid out.
Not in a direct mechanical sense. The bigger factors are UV exposure and Santa Ana wind, both of which operate regardless of what’s flying overhead. But the flight path does shape the job: crews deal with noise and vibration during tear-off, and no-drone or no-crane-window logistics apply when we’re staging materials. We schedule around it and keep the work moving. If you’re under the approach path and your roof is failing, call (855) 382-1073 for a free assessment.
