CertainTeed Construction in Westminster, CA | Workshop Contractors
We provide independent CertainTeed installation, repair, and replacement across Westminster, CA’s 92683, 92684, and 92685 ZIP codes, plus Midway City CertainTeed service just to the south. The one thing that makes our CertainTeed work here different is that we know these roofs and siding systems have to hold up against two things at once: Santa Ana winds that rip ridge caps off hips and gables, and a termite zone that eats fascia boards from the inside out. If you’ve got a CertainTeed roof or siding problem in Westminster, call us at (844) 384-3361, and we’ll tell you straight whether it’s a repair or a replacement.
Why Westminster Residents Choose Us for CertainTeed Service
Most of the CertainTeed roofs we work on in Westminster are Landmark architectural shingles sitting on 1950s-to-1970s stucco tract homes with shallow pitches and original skip-sheathing underneath. That combination fails in specific ways here, and we’ve seen enough of them to know what’s worth patching and what has to come off. Noel Figueroa, our owner and general contractor, grew up around tradesmen in Ontario’s Vineyard neighborhood and learned framing fundamentals at Chaffey College before spending decades on job sites across Southern California. He taught this crew the same principle he learned from his grandfather, who built the family’s house in Pomona with his own hands: build it right the first time. The second time costs twice as much and nobody’s happy about it.
We’re a full-scope general contractor, not a specialty roofer who disappears the minute the shingles are nailed down. When we re-roof a Westminster home with CertainTeed Landmark, we can also handle the fascia repair, the attic ventilation upgrade, the dry-rot replacement behind the siding, and the permit paperwork with Westminster’s own building department. One contract, one crew, one point of accountability for the whole exterior. For an independent provider that works with CertainTeed sales & service across Southern California, we carry genuine CertainTeed underlayments, starters, ridge caps, and hip-and-ridge pieces on most Westminster jobs, because those are the parts where the profile match actually matters.

Common CertainTeed Construction Problems We Solve in Westminster
- Granule loss and premature cupping on Landmark shingles. Westminster’s dry summers bake asphalt shingles on shallow-pitch tract roofs that never got the attic ventilation CertainTeed specifies. By year 12 or 15, we see shingles that look 25 years old. The fix is usually not another patch job. It’s re-roofing with proper intake and exhaust ventilation, and matching the CertainTeed Landmark profile the homeowner originally chose.
- Blow-off and ridge-cap loss during Santa Ana events. When re-roofs went over original skip-sheathing and the installer nailed high or ignored CertainTeed’s nail pattern, the shingles hold fine in mild weather. Then a 50-mile-per-hour Santa Ana hits and the ridge caps at gable ends peel like a zipper. We re-secure or replace the affected runs, but we always check the rest of the roof for the same nailing error before we call it done.
- Dry-rot under CertainTeed siding and fascia on older stucco homes. Westminster sits in a heavy subterranean termite zone. Garage conversion walls and siding terminations that shove CertainTeed siding tight against original framing trap moisture, and termites do the rest. We open up the affected area, replace the damaged framing, and re-detail the siding termination so water sheds instead of soaking in.
- Leaks at pipe boots, valleys, and wall-flashing tie-ins over piecemeal additions. Westminster’s tight lots have decades of added-on wings, converted garages, and enclosed patios. When a CertainTeed roof gets patched onto one of those additions without re-detailing the flashing to manufacturer spec, the valley or wall tie-in leaks within a season or two. We re-flash the intersection properly, and we pull the records before we bid.
- Failing CertainTeed XT25 or XTG roofs on original 1960s homes. These older fiberglass shingles were good roofs when installed, but after 25-plus years on a Westminster home, they’ve usually got granule loss at the eaves, brittle tabs, and rot at the rakes. We’ll replace them with Landmark architectural shingles, upgrade the ventilation, and replace any decking that’s gone soft.
CertainTeed Service in Westminster: What Local Conditions Mean for Your Equipment
Here’s something a generic CertainTeed page won’t tell you: Westminster runs its own building department with local plan check. That matters more than most homeowners realize. Because the city’s lots are small and homes have been added onto piecemeal since the Eisenhower administration, plan check routinely flags unpermitted prior work when you pull a permit for a re-roof. We’ve seen it happen repeatedly in 92683, where a garage got converted to an ADU in 1998 and nobody ever filed the paperwork. You call for a roof permit, and suddenly the city wants the addition brought to current code before the roof goes on. That’s why we do a records and pre-inspection check before bidding any CertainTeed re-roof over a converted garage or added-on wing in Westminster. It protects you from surprise change orders, and it tells us what we’re actually roofing over before we tear anything off. We’re a general contractor who manages the whole thing, not a roofing sub who calls plan check “your problem.”
CertainTeed Models & Products We Service in Westminster
We install and repair the full CertainTeed residential and light-commercial lines you find on Westminster homes. That includes CertainTeed Landmark and Landmark Pro architectural shingles, CertainTeed XT25 and XTG fiberglass shingles on older tract re-roofs, CertainTeed Monogram and Cedar Impressions siding for garage conversions and ADU exteriors, and CertainTeed Suspended Ceiling grid systems used in those converted interiors. For parts, our rule is simple: we use genuine CertainTeed shingles, underlayments, starters, and ridge caps wherever the warranty and profile match matters. For flashing, pipe boots, and some valley hardware, we use quality aftermarket pieces that outlast the OEM parts in Westminster’s coastal-inland sun. We’ll show you the difference and tell you why before we install anything.

AfterCertainTeed Service Pricing in Westminster
What you’ll pay depends on whether we’re repairing isolated wind or flashing damage or replacing an entire roof that’s reached the end of its service life. Here’s what we see across Westminster’s 1950s-70s tract stock:
| Scope | Typical Range in Westminster |

| Tile Roof Repair | $600 – $2,500 |
| Garage Conversion (including CertainTeed siding and interior grid) | $30,000 – $80,000 |
The spread exists because some 1960s Westminster homes have a single layer over skip-sheathing and good decking, while others have three layers, rotted rakes, and a plan check flag on a prior addition. Our free estimate includes the records check, an on-site inspection, and a written line-item quote so you know exactly what you’re paying for. Call (844) 384-3361 to schedule yours.

FAQs – CertainTeed Construction in Westminster
Yes, we can, and this happens all the time in Westminster’s 92683 ZIP. The process requires us to contact Westminster’s building department, do a records pull, and likely bring the unpermitted addition into plan check before the roof permit is issued. We manage that conversation for you, which is one reason homeowners choose a general contractor over a roofer for this kind of project. Call (844) 384-3361 and we’ll walk you through what your specific situation will require.
Almost always, it’s a ventilation problem. Westminster’s dry summers plus a shallow-pitch 1960s tract roof without upgraded attic ventilation bakes the asphalt and accelerates granule loss and cupping far faster than the shingle’s rated life. We address the full system: ventilation, underlayment, and the right CertainTeed profile for the pitch. For an exact diagnosis on your roof, call (844) 384-3361.
We open up the affected area, remove the damaged framing and sheathing, treat the surrounding wood, and replace it with code-compliant lumber. Then we re-detail the CertainTeed siding termination so water sheds away from the structure. Because Westminster sits in a heavy subterranean termite zone, we check the full fascia run and all siding terminations whenever we open a wall, not just the visible damage. Call (844) 384-3361 for a free inspection.
Generally yes, a properly installed standing-seam or metal roof resists wind uplift better than an architectural shingle, especially at hips and gables where Santa Ana winds concentrate. That said, a correctly fastened CertainTeed Landmark roof with manufacturer-spec nail patterns and upgraded ridge caps handles Westminster’s wind events fine. We install both in Westminster and offer CertainTeed in Stanton as well, and we’ll give you a straight comparison for your roof’s pitch and exposure.
It depends on what the leak is doing to the decking underneath. If the valley flashing failed because a prior addition was patched on without re-detailing, and the deck and framing are still solid, a targeted re-flash is the honest repair. If moisture has been running into the deck for a season or two and the wood is compromised, patching just buys you a year. We’ll open it up and show you what we find before we recommend anything. Call (844) 384-3361 and we’ll take a look.
