Why Lennox Residents Choose Us for CertainTeed Service
Rick Dominguez grew up off Sepulveda Boulevard, a few blocks from the old Van Nuys Municipal Airport, and spent two decades on rooftops across the San Fernando Valley before starting Van Nuys Roofing Co. He learned the trade through the construction technology program at Los Angeles Valley College over in Valley Glen, and he’s known for flat roof work and for being straight with people about what actually needs fixing versus what can wait another season. That’s the mindset our crews bring to every Roof Repair in Lennox and CertainTeed job.
We work with seven major roofing brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – which means we don’t push one manufacturer because it’s easier for us. For Lennox homeowners weighing repair against replacement on a mid-century stucco bungalow or a small duplex, that’s a real difference compared to CertainTeed in Hawthorne. We know CertainTeed’s install specs, warranty paperwork, and failure patterns, and we’ll tell you plainly when a roof has life left and when it’s done. If it doesn’t need replacing, we’re not going to tell you it does.
As an independent contractor, not a manufacturer-affiliated dealer, we’re not bound to one product line. Your roof, your material choice. We handle CertainTeed sales & service the same way for a steep-slope duplex as for a low-slope flat roof – with the right components and honest advice.

Common CertainTeed Roofing Problems We Solve in Lennox
CertainTeed products are solid, but Lennox has a specific set of conditions that stress them in predictable ways. Here’s what we see most often on the ground:
- Wind uplift at the perimeter and ridge on Landmark architectural shingles. Santa Ana gusts off the South Bay hit Lennox hard, and where the original drip edge or starter course was never upgraded, we find shingles lifted or torn right at the eave line. The March and October wind events are the usual culprits.
- Granule loss and sun-baked aging on XT 25 three-tab roofs. The older 1940s-60s stucco bungalows in Lennox often still carry their original three-tab, now 20+ years past its service life. The south-facing slopes cook under coastal UV, and the granules end up in the gutters. That roof is generally a replace, not a repair.
- Adhesive strip failure on Presidential Shake installs. Those thick luxury shingles are heavy, and on older narrow-lot framing the sheathing flexes just enough that the self-seal strips let go at the rakes and valleys. Wind-driven rain follows. We see this on high-end Lennox remodels where the shake was added years after the original framing.
- Marine-moisture wear and seam lifting on low-slope DiamondDeck and Flintlastic membranes. Salt-laden air off the coast accelerates membrane aging on the small duplexes and low apartment buildings throughout Lennox. Blistering near drains, ponding water, and seam lift are the telltale signs.
- Failed vent boots and flashing on otherwise healthy CertainTeed roofs. Not every leak is a roof failure. We fix a lot of isolated vent boots, pipe collars, and valley flashing issues on roofs that still have five to ten years left.
CertainTeed Service in Lennox: What Local Conditions Mean for Your Equipment
Most Lennox roofs sit on narrow lots under the LAX flight path, and that changes CertainTeed work here in ways a homeowner in El Segundo or someone seeking Inglewood CertainTeed service might not think about. Our crews time tear-off and dumpster placement around overhead traffic and jet noise – a 1950s stucco bungalow on a 5,000-square-foot lot doesn’t have room for a 20-yard dumpster in the driveway, so we stage it in the alley or on the street with the city’s blessing. Tight alley access and a complete lack of street parking on some blocks mean we sequence material deliveries differently than we would on a roomier South Bay lot. And because the houses are packed close together, we tarp and magnet-sweep every day so your neighbor’s patio doesn’t end up with a layer of roofing nails.
On a compact 1950s stucco bungalow off the dense blocks near 90304, we pulled a sun-baked Landmark architectural roof that had lost granules across the south-facing slope and was lifting at the rake from Santa Ana gusts. Once the tear-off exposed soft original sheathing, we repaired the deck, replaced the starter and drip edge, and re-roofed in Landmark with new ridge caps – timed so our dumpster and crew wouldn’t block the alley under the flight path. That’s how every Lennox job gets planned.
CertainTeed Models & Products We Service in Lennox
We work on the full range of CertainTeed roofing product lines common in Lennox:
- Landmark architectural shingles – the most common roof on Lennox bungalows and duplexes. We install the full system: starter, shingles, ridge caps, and accessories.
- XT 25 / XT 30 three-tab shingles – mostly tear-offs on original 1940s-60s roofs, but we will match and repair isolated damage where the roof still has life.
- Presidential Shake luxury shingles – steep-slope replacements and repairs where the adhesive strips have failed or UV has degraded the surface.
- DiamondDeck cap sheet and Flintlastic low-slope membranes – flat and low-slope work on the many small duplexes and apartment buildings in Lennox.
We use genuine CertainTeed shingles, starter, ridge caps, and accessory components where the product line calls for them. Where OEM isn’t required – underlayment, drip edge, flashing – we use quality matching materials, never an off-brand substitution hidden behind a CertainTeed label. The parts are on the roof for 20 to 30 years. They either match or they don’t.

AfterCertainTeed Service Pricing in Lennox
CertainTeed roof replacement in Lennox typically runs from $8,500 to $22,000 depending on roof size, pitch, tear-off complexity, and the product line – Landmark architectural is the mid-range standard, Presidential Shake runs higher, and low-slope Flintlastic work on a duplex can range from $9,000 to $18,000. Isolated repairs like a wind-lifted shingle or a failed vent boot usually land between $350 and $850. What drives the cost in Lennox specifically is access: tight alleys, parking constraints, dumpster staging, and flight-path scheduling all factor into how we plan a job.
Our free estimates include a written line-item quote, an honest assessment of what’s actually wrong, and a recommendation on repair versus replace. If the roof has life left, we’ll say so. If it’s done, we’ll tell you that too. Call (866) 321-6172 to schedule yours – no pressure, just numbers.

FAQs – CertainTeed Roofing in Lennox
Bubbling near the drain is almost always a replace, not a repair. Marine air in Lennox accelerates seam lift and blistering on low-slope DiamondDeck and Flintlastic membranes, and by the time you see blisters, the membrane has usually lost its bond in enough spots that patching would be throwing money at a losing roof. We’ll do a core cut and check the underlayment before we give you a recommendation, but expect the answer to be replacement. Call (866) 321-6172 for a free membrane assessment – we’ll tell you honestly what the roof needs.
Landmark architectural shingles are the right fit for most gently pitched Lennox bungalows – they’re rated for the pitch, they handle Santa Ana wind better than three-tab, and they carry a solid warranty. If the pitch is below 2:12, you need a low-slope system like Flintlastic instead. We’ll check the framing and sheathing before recommending a product, because some of these 1940s structures weren’t built for heavier lines like Presidential Shake.
It’s likely, and we factor that possibility into the quote. Most Lennox homes date from the 1940s to 1960s, and the original sheathing is often soft or delaminated after 60 to 80 years of marine air and occasional roof leaks. We won’t know for sure until the tear-off. What we do is quote the roof and list sheathing repair as a per-sheet cost so there are no surprises – the quote stays transparent even when the deck needs work.
We plan around the access, not through it. On a tight Lennox lot, that means staging the dumpster in the alley or on the street with a permit, timing tear-off and material delivery around the heaviest overhead traffic, and keeping a clean tarped site every day so nails don’t end up in the neighbor’s yard. We’ve done enough Lennox tear-offs to know which blocks have alley access and which don’t – it’s part of the estimate.
Most Lennox CertainTeed replacements land between $8,500 and $22,000, with the typical mid-century bungalow in Landmark falling in the $11,000 to $16,000 range. Low-slope membrane replacements on duplexes run $9,000 to $18,000. The exact number depends on your roof’s size, pitch, deck condition, and access. Call (866) 321-6172 for a line-item quote – it’s free, and it’s the only way to get a real number for your specific roof.
