CertainTeed Roofing in Del Aire, CA | Van Nuys Roofing Co
CertainTeed roofing service in Del Aire covers repair, replacement, and inspection of Landmark, XT 25, Independence, and Flintlastic systems across the 90251 zip code. Del Aire sits close enough to the coast that salt fog and jet soot from LAX traffic eat certain roofing components years before the shingles themselves would normally wear out. We’re an independent CertainTeed service provider, not manufacturer-authorized, which means we’ll tell you straight whether a patch, a flashing fix, or a full re-roof actually makes sense. Call (866) 321-6172 for a free estimate.
Why Del Aire Residents Choose Us for CertainTeed Service
We work with seven major roofing brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – and that matters in a place like Del Aire. A shop that only pushes one shingle can’t tell you honestly whether CertainTeed is the right call for your particular roof. We can. Our crew has torn off and reinstalled enough CertainTeed roofs in this small unincorporated pocket to know which failure modes show up first under marine moisture and which products handle it.
Rick Dominguez runs our operation, and he grew up a few miles north off Sepulveda Boulevard. He learned roofing through the construction technology program at LA Valley College and spent close to two decades on San Fernando Valley rooftops before starting Van Nuys Roofing Co. His standard line: “If it doesn’t need replacing, I’m not going to tell you it does.” For more on our approach, see our CertainTeed sales & service page.

Common CertainTeed Roofing Problems We Solve in Del Aire
Here’s what we actually find when we walk CertainTeed roofs in Del Aire:
- Granule loss hidden by jet exhaust soot. Landmark and XT 25 shingles on homes under the LAX flight path collect fine soot that masks surface erosion. The shingles look dark and intact from the ground, but the asphalt mat underneath is already brittle. We see this on second-generation CertainTeed roofs throughout the 1940s and 1950s tract home sections.
- Corroded fasteners and flashing years before shingle failure. Salt-laden fog off El Segundo and Manhattan Beach eats galvanized nails and valley flashing fast. Leaks at penetrations and valleys are usually the first sign – not worn shingles.
- Ponding on low-slope sections. Many Del Aire homes have flat or low-pitch additions where architectural shingles were installed below the manufacturer’s 2:12 minimum. Marine moisture sits there, the mat rots, and the roof fails early.
- Ridge vent and vent boot rust-through. Damp salt air rusts steel ridge vents and rubber boots on CertainTeed roofs in eight to twelve years. Attic leaks stay silent until decking softens. We catch this during standalone inspections before it becomes a plywood replacement job.
- Valley flashing that fails before the shingles around it. Del Aire’s wet-morning climate keeps valley metal wet longer than the shingle field. On CertainTeed installs with stock galvanized flashing, the valleys fail first. We swap to aluminum flashing on every repair here.
CertainTeed Service in Del Aire: What Local Conditions Mean for Your Roof
Del Aire is unincorporated LA County, not part of Hawthorne or El Segundo. That distinction shapes every re-roof we do here. Permits and inspections run through LA County Building & Safety, and county inspectors specifically flag low-slope CertainTeed installs that fall below the 2:12 pitch limit. That matters a lot in a community built mostly in the 1940s through 1960s, where single-story tract homes often have flat or barely sloped rear additions. We’ve been called to properties where a previous roofer put architectural shingles on a 1.5:12 patio cover and the whole section rotted from trapped marine dampness. The county catches it. So do we – before we install anything. On a 1952 single-story tract home near the airport corridor, we tore off two layers of CertainTeed XT 25 shingles that looked fine from the curb but were paper-thin from soot-hidden granule loss and salt corrosion. The valley flashing had rusted through completely. We replaced it with aluminum, installed new CertainTeed Landmark architectural shingles on the main pitch, and used Flintlastic cap sheet on the low-slope rear addition. It passed LA County inspection on the first try.
CertainTeed Models & Products We Service in Del Aire
We handle the full CertainTeed residential line you’re likely to find on Del Aire tract homes. CertainTeed Landmark architectural shingles show up most often on re-roofs from the last two decades. XT 25 three-tab shingles are common on older original roofs. Independence GlassMatt shingles appear on some mid-century homes, and Flintlastic cap sheet is the standard for the low-slope sections that plague Del Aire additions. For repairs, we stock genuine CertainTeed accessories – shingles, starter strips, ridge caps, Flintlastic membranes – so color matching is straightforward. But we deliberately use quality aftermarket corrosion-resistant fasteners and aluminum flashing instead of OEM galvanized versions, because the galvanized parts fail fast in Del Aire’s salt fog. On a 25% plus granule loss roof or one with active ponding, we recommend replacement over patching. Layering new shingles over failed ones just traps moisture and guarantees the same problem returns. We also provide Del Aire service area coverage for inspections, repairs, and full replacements.

FAQs – CertainTeed Roofing in Del Aire
Yes, Del Aire is unincorporated LA County, so a full CertainTeed re-roof requires a permit through LA County Building & Safety, not Hawthorne or El Segundo. And yes, county inspectors will flag CertainTeed architectural shingles installed below the manufacturer’s 2:12 minimum pitch. If your low-slope section is below that threshold, we use Flintlastic cap sheet instead. Call (866) 321-6172 if you want us to check your roof’s pitch before you commit to anything.
Two ways. The salt fog accelerates corrosion of fasteners, flashing, and ridge vents, often causing leaks years before the shingles wear out. And the fine jet exhaust soot from LAX flight path homes settles on the shingle surface and hides granule loss, so roofs can look fine while the asphalt mat underneath is already degrading. In Del Aire, we see Landmark roofs that would normally last 25 – 30 years start showing problems in 18 – 22. Call (866) 321-6172 for a free inspection.
Usually, yes. Valley flashing is a targeted repair. We lift the surrounding shingles, remove the rusted galvanized metal, swap in aluminum flashing, and re-secure the shingles. It typically takes part of one day. If the shingles around the valley are too brittle to re-secure, you may be looking at a partial replacement, but we’ll show you photos before we recommend spending more. Call (866) 321-6172 to schedule a look.
For sections below 2:12 pitch, the correct product is Flintlastic cap sheet or another CertainTeed low-slope membrane system, not architectural shingles. Shingles on too-low pitch trap moisture and rot. Lots of Del Aire rear additions were originally built this way and failed early. We install Flintlastic on those sections and shingles on the steeper main roof. Call (866) 321-6172 if you want us to assess your slopes.
The marine layer here keeps moisture on roof surfaces much longer than inland, and the salt content in that fog corrodes steel components quickly. Factory ridge vents and rubber vent boots on CertainTeed roofs in Del Aire commonly fail in eight to twelve years. We replace them with corrosion-resistant alternatives. Call (866) 321-6172 to have yours checked.
