CertainTeed Roofing in Westminster, CA | Van Nuys Roofing Co
We provide independent CertainTeed roofing service across Westminster, from inspections and shingle matching to full replacements. What sets our CertainTeed work here apart is that we know how these shingles actually age on Westminster’s shallow-pitch 1960s tract roofs, where salt air and UV hit differently than they do ten miles inland. Call (866) 321-6172 for a straight answer about your roof.
Van Nuys Roofing Co is not a CertainTeed dealer and we don’t carry manufacturer authorization. We’re an independent roofer who works with seven major brands, including CertainTeed, which means our recommendations come from what’s on your roof, not from a supplier contract. For CertainTeed sales & service guidance, we apply the same standard: inspect first, recommend second.
Why Westminster Residents Choose Us for CertainTeed Service
Most roofing crews in Westminster know one brand and push it. We know seven, and CertainTeed is one of the ones we see most often on the 1950s through 1970s tract homes that make up so much of this city. That matters when a homeowner off Bolsa Avenue asks whether their failing slope can be repaired or needs a full re-roof. We can answer from experience, not from a catalog.
Rick Dominguez, our owner, grew up off Sepulveda Boulevard in Van Nuys and learned the trade through the construction technology program at Los Angeles Valley College. He’s spent the better part of two decades on rooftops across Southern California, and he’s known for flat roof work and for being straight with people. His rule is simple: “If it doesn’t need replacing, I’m not going to tell you it does.” That’s the approach we bring to every CertainTeed roof we touch in Westminster.
We also coordinate bilingually. Westminster’s Vietnamese-American community is a huge part of this city, and plenty of our customers prefer discussing a roof in Vietnamese with a crew member who can explain underlayment, scupper rebuilds, and warranty paperwork clearly. It’s not a service we advertise. It’s just how we work here.

Common CertainTeed Roofing Problems We Solve in Westminster
- Granule loss and surface cracking on south-facing slopes. Westminster gets more than its share of direct sun, and the marine air off the coast carries salt that eats at the asphalt binder in CertainTeed Landmark and XT shingles. We see granule-bare patches and fine surface cracks on south-facing roof planes years before the warranty would suggest they should appear. Repair means matching the profile and color lot wherever the run is still serviceable.
- Brittle, curling three-tab shingles on original 1970s tract roofs. The original CertainTeed three-tab installs across Westminster’s tract housing are now 50 years old. Tab edges curl, fasteners back out, and underlayment gets exposed. When we find whole planes in that condition, chasing individual shingles is a waste of the homeowner’s money. We say so.
- Seam failures on low-slope Flintlastic sections east of Beach Boulevard. The blocks east of Beach have a pattern we know well: shallow-pitch roofs with minimal insulation and undersized scuppers. Water pools after winter rain, sits on the membrane laps, and eventually finds a seam. The leak shows up at the fascia, not where the seam failed. That’s a diagnostic detail that keeps us from tearing off the wrong section.
- Rusted drip edge and vent boots from salt-laden coastal air. CertainTeed shingles can outlive the metal around them in Westminster. Galvanized fasteners, drip edge, and vent boots corrode in the salt air, and the roof starts failing at the edges while the shingle field still looks fine. We replace the corroded metal and re-secure the perimeter before addressing shingles.
- Fascia staining from underbuilt scuppers on 1960s flat sections. This is the classic Westminster flat roof problem. The scuppers were undersized from the start, so the first real rain after a dry spell sends water pooling against the fascia board. The board rots, the stain spreads, and the homeowner thinks the roof membrane failed. Often the membrane is fine; the drainage is the problem. We rebuild the scupper detail and then assess the membrane honestly.
CertainTeed Service in Westminster: What Local Conditions Mean for Your Equipment
Westminster’s 1960s flat and low-slope tract roofs were built with minimal insulation and undersized scuppers. That’s not a generalization; it’s a construction pattern we see over and over in the blocks east of Beach Boulevard. The first significant rain after a dry spell sends water pooling against the fascia, because the roof doesn’t have enough positive drainage to clear it. For a homeowner with a CertainTeed system on one of these roofs, the failure they notice is usually fascia staining or a drip line along the outer wall, not an obvious roof breach.
What this means for CertainTeed owners specifically: the shingle or membrane might not be the problem at all. The drainage is. When we’re called to a leaking low-slope roof in Westminster, we check the scuppers and the slope before we assume the CertainTeed product failed. Sometimes we rebuild the scupper and the leak stops. Sometimes the membrane has seam failure from years of ponding, and then it’s a Flat Roof Patch with Flintlastic SA self-adhered modified bitumen, which is the right product for low-slope sections. Either way, we start with why the water is sitting there, because patching a membrane without fixing the drainage just moves the leak to the next seam.
CertainTeed Models & Products We Service in Westminster
We handle the CertainTeed product lines that actually appear on Westminster roofs. That includes Landmark architectural shingles, XT 25 and XT 30 three-tab shingles, Presidential Shake luxury shingles, and Flintlastic SA self-adhered modified bitumen for low-slope work. When we repair a run that’s still serviceable, we use genuine OEM-profile CertainTeed shingles so the color lot and profile match the existing roof. That matters on visible slopes, where a mismatched repair announces itself from the street.
For flat sections, we stock Flintlastic SA locally because it’s the product that handles Westminster’s low-slope drainage conditions. We keep common Landmark color profiles available for fast turnaround on shingle replacement and flashing repair, but unusual color lots may take a few days to source. A free estimate will tell you what’s available immediately.

AfterCertainTeed Service Pricing in Westminster
CertainTeed shingle replacement in Westminster typically runs $15 to $30 per square foot depending on the product line, slope, and how much of the existing system needs rebuilding. Flat roof patches with Flintlastic SA start around $12 per square foot but climb if the scupper detail and edge metal need reworking. Flashing repair is usually the most affordable repair we quote, because the problem is often isolated to one penetration or one wall junction.
Your estimate includes a roof inspection, a written line-item quote, and a straight answer about whether a repair makes sense or the roof is past 20 years and needs full replacement. We don’t charge for pressure and we don’t pad the quote with work you don’t need. Call (866) 321-6172 for exact pricing on your CertainTeed roof.

FAQs – CertainTeed Roofing in Westminster
Yes, if the remaining run is still serviceable, we match the color lot and profile with OEM-compatible CertainTeed shingles so the repair blends on the visible slope. When the aging is widespread across multiple planes, we’ll tell you that replacement is the smarter spend. Call (866) 321-6172 to have us assess which situation you’re in.
Because the shallow-pitch sections on Westminster’s 1960s tract homes don’t drain fast enough, so water ponds and sits on membrane seams until it finds a way through. The leak often appears at the fascia, not where the water entered. We rebuild the drainage or patch the seam depending on what we find on the roof itself.
It does. The marine air attacks the asphalt binder in the shingles and corrodes the galvanized fasteners and drip edge, so Westminster roofs often fail at the edges and fasteners while the shingle field still looks acceptable. We inspect the metal as part of every CertainTeed service call here.
Flintlastic SA self-adhered modified bitumen is the standard product for low-slope sections, because it handles ponding and irregular surfaces better than shingles on shallow pitches. We check the scuppers and slope before recommending any patch, because on many Westminster flats the drainage is the real problem.
If we’re replacing a full slope with Landmark architectural shingles, the profile will look slightly different from the original three-tab, but that’s usually an improvement in both appearance and performance. If we’re repairing a small section, we match the existing profile and color lot as closely as OEM stock allows. Either way, we show you samples before work starts. Call (866) 321-6172 for a free estimate and we’ll walk you through the options.
