CertainTeed Roofing in Lennox, CA | Koreatown Roofing
We provide independent CertainTeed roofing service across Lennox, CA (ZIP 90304), just minutes from CertainTeed service in El Segundo. If you own a rental fourplex or a post-war bungalow here and the roof is showing its age, we handle everything from leak repair to full tear-off. The thing that makes our CertainTeed work different in Lennox is simple: we actually understand how LAX soot and the unincorporated county permit path shape what your roof needs. Call us at (866) 974-2271 for a straight answer.
Why Lennox Residents Choose Us for CertainTeed Service
We’re a roofing-only contractor, not a generalist juggling three trades. That means when a Lennox landlord calls about a CertainTeed Landmark roof that’s losing granules, we know exactly what we’re looking at before we climb the ladder. Manny Cordero, our owner, learned the trade through the building trades program at Los Angeles Trade-Technical College, where instructors drilled material specs and installation sequencing into him long before he ever touched a customer’s house. He’s been working roofs in this part of LA County for over two decades, and he still explains things the way he’d want them explained to him: straight, no upsell, no mystery. We’re also independent. We’re not a CertainTeed-authorized dealer with a quota to hit, and we’re not pushing one brand because it’s convenient. We carry materials from seven manufacturers including GAF, Owens Corning, IKO, Atlas, Tamko, and Boral. That means when we recommend CertainTeed for a Lennox roof, it’s because the product actually fits the job. If another material fits better, we’ll tell you that too. Your roof, your material choice.
We handle CertainTeed sales & service with the same approach we use on every job: inspect first, explain clearly, price honestly. In Lennox, where most roofs are low-slope or shallow-pitch and the housing stock is dense post-war construction, that matters more than in neighborhoods with newer single-family homes. You don’t need a sales pitch. You need someone who knows the difference between a shingle that can be repaired and a deck that’s quietly rotting underneath.

Common CertainTeed Roofing Problems We Solve in Lennox
Here’s what we see most often on CertainTeed roofs in this specific corner of LA County:
- Landmark granule loss and edge curling on shallow-pitch bungalows. Lennox gets intense UV exposure, and the airborne soot from LAX and the nearby freeways settles on roof surfaces and accelerates shingle aging. We regularly see Landmark shingles on these older stucco bungalows losing granules faster than you’d expect, with curling at the edges where the pitch is too shallow for standard shingle drainage.
- Flintlastic SA membrane cracks at seams and ponding areas. Flat and low-slope roofs throughout Lennox fail by membrane cracking and dried-out sealant, not freeze damage. The thermal cycling between hot basin days and cool nights stresses self-adhered modified bitumen at the seams, and ponding water finds every weak point. We patch these properly, but we also check whether the ponding itself is a drainage problem that will just re-crack the patch in a year.
- Presidential SolarReflective algae streaking and adhesive breakdown. These shingles are built for heat reflection, but Lennox’s minimal attic ventilation in 1940s and 1950s construction means heat gets trapped under the deck. We see adhesive degradation and algae streaking on Presidential roofs where the attic never got proper ventilation and nobody ever addressed it.
- Highland Slate hiding soft decking and nail pops. Highland Slate is a heavier shingle, and Lennox homes built in the 1940s through 1960s often still have original sheathing underneath. When we pull old shingles, we find soft spots and nail pops where the deck has deteriorated over 60-plus years. The shingle looked fine from the ground. The deck underneath didn’t.
- Leaks at vent boots and valleys on fourplex roofs. Lennox’s rental fourplexes are tightly packed, and many roofs were originally installed with minimal flashing detail. Years of thermal expansion plus dried-out sealant around vent boots and valleys means active leaks that tenants notice before landlords do. We fix the source, not just the ceiling stain.
CertainTeed Service in Lennox: What Local Conditions Mean for Your Roof
Here’s something a roofer from Burbank or Torrance won’t tell you about Lennox: every CertainTeed roof permit here goes through LA County Building & Safety, not a city hall. Lennox is unincorporated, which sounds like a bureaucratic footnote until you’re the one waiting on a permit while winter rain is in the forecast. We’ve done enough work here—and on nearby CertainTeed service in Del Aire—to know how the county handles roofing permits, what triggers an inspection, and how to sequence the job so you’re not left with an open roof longer than necessary.
Add in the tight lot lines and the fact that many Lennox fourplexes share property lines with neighboring buildings, and the real constraint on a roof replacement here is often access, not material. We routinely stage materials over shared property lines, coordinate with adjacent property owners, and plan the tear-off so debris doesn’t end up in someone else’s courtyard. On a fourplex near 104th Street and Firmona Avenue, we found a Landmark shingle roof with severe granule loss and active leaks at the vent boots and valley. After pulling the old shingles, we replaced soft decking, installed new CertainTeed Flintlastic SA on the low-slope section, and finished with matching Landmark shingles. The landlord had a watertight roof before the winter rains hit. That’s the kind of job that makes you plan the access before you order the materials.
CertainTeed Models & Products We Service in Lennox
We service the CertainTeed lines that actually show up on Lennox roofs: Landmark Series architectural shingles, Presidential SolarReflective, Highland Slate, and Flintlastic SA self-adhered modified bitumen for low-slope and flat sections. We use genuine CertainTeed accessories and matching shingles whenever they’re available, because color match and wind rating consistency matter on a repair. But we’re also practical about it. For low-slope repairs in Lennox, we sometimes recommend a quality aftermarket membrane when it offers better long-term performance under ponding water and LAX soot than the original CertainTeed product. We stock common CertainTeed shingle colors locally to keep Lennox turns quick, and we’ll never hold up a leak repair waiting on a specialty order without telling you the timeline first.

AfterCertainTeed Service Pricing in Lennox
Roof repair pricing in Lennox follows the same pattern as the rest of LA County, but the local housing stock tilts the numbers. A simple leak repair or shingle replacement on a Landmark roof typically runs $350 to $850 depending on access and the extent of the damage. A Flintlastic SA patch on a flat or low-slope section tends to land between $600 and $1,400, especially when we’re addressing a ponding area or a seam that’s opened up. A full tear-off and re-roof on a Lennox fourplex with new decking where needed usually runs $12,000 to $22,000, with the spread driven mostly by deck condition and roof pitch. We give line-item written estimates, and our pricing doesn’t change mid-job once we’ve agreed on the scope. The free estimate includes a roof inspection, photos of what we find, and a straight recommendation on whether you need a repair or a replacement. Call (866) 974-2271 and Manny or one of our crew leads will walk you through it.

FAQs – CertainTeed Roofing in Lennox
Yes, you need a permit, but it goes through LA County Building & Safety because Lennox is unincorporated. That’s a different office and a different process than going through the City of Hawthorne or Inglewood. We handle the county permit paperwork, schedule the inspection, and make sure the job passes on the first visit. If you’re only doing a patch or a few shingles, a permit typically isn’t required, but we’ll tell you upfront either way. Call (866) 974-2271 if you want us to check your specific project.
Most Lennox bungalows with a shallow pitch do better with a self-adhered modified bitumen product like Flintlastic SA on slopes below 2:12, rather than forcing Landmark shingles where drainage is marginal. Landmark shingles work well on slopes above 3:12, but on those older shallow-pitch Lennox roofs, the shingle can’t drain properly and you accelerate granule loss and edge curling. We’ll measure the slope, look at the deck, and recommend the product that actually fits the roof geometry, not just the one you’ve heard of. For an exact recommendation on your roof, call (866) 974-2271 – estimates are free.
LAX flight paths and the 405/105 traffic put fine soot and particulate matter onto Lennox roofs, and that soot traps moisture and heat against the shingle surface. Over time, it accelerates granule loss and makes algae streaking more visible, especially on Presidential SolarReflective shingles. The effect is worse on Lennox fourplexes where roofs rarely get cleaned and attic ventilation was never added. We factor that into every inspection here, because a roof that looks 10 years old in Lennox may actually be 15 or 20 years old with soot-accelerated wear.
Yes, in many cases a Flintlastic SA low-slope roof in Lennox can be patched at the seams and ponding areas rather than replaced, as long as the underlying insulation and deck are still dry and sound. We use heat-welded or self-adhered patches depending on the membrane condition, and we’ll tell you honestly if the membrane is too far gone to patch. The deciding factor is usually whether water has already gotten into the insulation or the deck. If it has, a patch is just a bandage. Call (866) 974-2271 and we’ll inspect it before recommending anything.
Get a tarp on the leaking area from a roofer who can access it safely, then call us at (866) 974-2271. In Lennox, post-storm leaks on CertainTeed roofs are usually at vent boots, valleys, or low-slope membrane seams that opened up after heavy rain. We’ll trace the leak to the source, not just the stain, and we’ll give you a repair quote that addresses the actual failure point. If the deck is wet, we’ll tell you what that means for the repair scope before we touch anything.
