CertainTeed Roofing in Lomita, CA | Van Nuys Roofing Co
We provide independent CertainTeed roofing service across Lomita and nearby areas like CertainTeed in Torrance, from tear-offs to targeted repairs. The thing that makes our CertainTeed work here different is simple: we know how Landmark and Presidential systems behave under the marine layer that sits over 90717 most mornings. If your CertainTeed roof looks fine but you smell damp in the attic, call (866) 321-6172 before it becomes a decking job nobody budgeted for.
Why Lomita Residents Choose Us for CertainTeed Service
CertainTeed makes good roofing products. But a shingle is only as good as the deck under it and the flashing around it. That’s where Lomita gets tricky. We’ve pulled enough CertainTeed fields off 1950s tract houses here to know that the shingles usually aren’t the problem. The problem is what the salty onshore air and morning damp have done underneath them.
Rick Dominguez grew up off Sepulveda Boulevard and spent two decades on roofs across the South Bay before starting Van Nuys Roofing Co. His rule is the same one he learned doing construction tech at L.A. Valley College: “If it doesn’t need replacing, I’m not going to tell you it does.” That’s why we sell CertainTeed sales & service the way we do. We probe the deck before we quote shingles. We replace what’s actually failing. And we never ask you to pay for a full re-roof when a re-flash and two new sheets of plywood fixes it.
We’re the crew that knows seven major roofing brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – not because it looks good on a flyer, but because Lomita’s housing stock throws a different roofing problem at you on every block. Fluent in seven means your recommendation comes from the roof’s condition, not from whatever brand we happen to stock.

Common CertainTeed Roofing Problems We Solve in Lomita
- Rusted-out fasteners under intact-looking Landmark shingles. Lomita’s salt-laden onshore breezes eat standard galvanized nails and vent boots. We regularly find rusted-through fasteners under CertainTeed shingles that still look like they have ten years left.
- Soft, delaminating original 1950s wood sheathing. The marine layer keeps morning moisture pressed against old deck boards along the Palos Verdes-adjacent tracts. Shingles look fine. The deck under them is mush. This is our most common Lomita discovery.
- Flashing and valley failure on shallow-pitch roofs near Lomita Boulevard. Older stucco tract homes with low-slope roof sections often got steep-slope Landmark laid where a low-slope-approved membrane should have gone. Water ponds, seams fail, and leaks follow.
- Ceiling stains that don’t match any visible shingle damage. When the roof’s moisture problem is underneath – not on top – the first sign is usually a brown ring on the living room ceiling. By then, the decking has been rotting for a while.
- Underlayment failure preceding shingle granule loss. Lomita gets less harsh UV than inland L.A., so CertainTeed shingles here age slowly on the surface. The underlayment beneath them doesn’t. Owners are often surprised when we tell them the roof is done while the shingles still look decent.
CertainTeed Service in Lomita: What Local Conditions Mean for Your Equipment
Here’s the Lomita-specific fact that shapes every CertainTeed job we do here. The older tracts off Lomita Boulevard were sheathed in original 1950s wood that the marine layer keeps damp most mornings. So on nearly every CertainTeed tear-off in this part of 90717, we budget for partial redecking that the intact-looking shingle field gave no hint of. You can’t see it from the street. You can’t see it from the attic. You only find it when the shingles come off and you can push a screwdriver through what used to be plywood.
That’s the reality of CertainTeed service in Lomita that no generic roofing page tells you. Areas like CertainTeed in West Carson get sun-baked brittle shingles. We get invisible deck rot under shingles that look fine. Our estimating treats every Lomita tear-off as a possible redecking job until the deck is exposed and probed. It’s the only honest way to quote this neighborhood.
CertainTeed Models & Products We Service in Lomita
We work on the CertainTeed product lines that show up most often on Lomita roofs. Landmark architectural shingles on the steeper gable sections. Presidential Shake and Presidential TL on higher-end homes where the owner wanted the premium look. And Flintlastic SA modified-bitumen membrane on the low-slope and flat sections that are so common on the shallow-pitch tract houses in this area. We also handle CertainTeed XT25 and RoofRunner underlayment, plus SwiftFlash flashing accessories.
Our parts approach is this: when a CertainTeed roof gets repaired, it gets genuine CertainTeed components. Landmark shingles, Flintlastic membrane, matching underlayment, matching SwiftFlash. Mixing brands in one roof assembly is where callbacks come from, and we don’t want the callback. We keep the common Landmark colors and Flintlastic materials stocked for fast Lomita turnaround, so a repair doesn’t turn into a three-week parts wait.

AfterCertainTeed Service Pricing in Lomita
CertainTeed roofing work in Lomita varies widely depending on what we find when the deck is exposed. A targeted flashing and vent-boot repair usually runs $350 to $800. A larger repair with partial redecking and new underlayment: $2,500 to $6,000. A full CertainTeed Landmark tear-off and re-roof on a typical 1950s Lomita tract house, including the partial redecking we plan for here, typically lands between $14,000 and $22,000.
What drives the difference is deck condition. Lomita’s marine layer means we often replace sheathing that looks fine until it’s probed. A free estimate from us includes getting on the roof and checking what’s actually there. Call (866) 321-6172 to schedule yours. No charge, and you’ll know what the job really needs.

FAQs – CertainTeed Roofing in Lomita
Because in Lomita, the shingles are rarely the part that fails first. The salty onshore air and morning marine layer corrode fasteners and rot the original 1950s wood sheathing under shingles that still look intact. The roof’s failing from underneath. Call (866) 321-6172 and we’ll inspect the deck, not just the shingles.
Lomita’s persistent marine layer keeps damp, salt-laden air against your roof’s metal components every morning. Standard galvanized nails and vent boots corrode faster than the CertainTeed shingles above them wear out. That’s why we replace fasteners and flashing with corrosion-resistant materials when we re-roof in 90717.
On most original 1950s tract houses in Lomita, yes, at least partially. The original wood sheathing has been absorbing marine-layer moisture for sixty-plus years. We won’t know the full extent until the old shingles come off, but we plan for it in every quote. Call (866) 321-6172 for a deck assessment.
We install Flintlastic SA modified-bitumen membrane on low-slope and flat sections, and Landmark architectural shingles on properly pitched slopes. Putting steep-slope shingles on a low-slope Lomita roof is how you get ponding water and seam leaks. We match the product to the pitch, every time.
No. We’re an independent roofing contractor with extensive CertainTeed experience, not a manufacturer-authorized or sponsored installer. That independence means our recommendations aren’t steered by a manufacturer relationship. Your roof gets what it needs, not what we’re incentivized to sell. Estimates are free at (866) 321-6172.
