CertainTeed Construction in Westminster, CA | Sycamore Contractors
If you own a 1950s or 1960s ranch home in Westminster, there’s a good chance your CertainTeed roof is telling you something right now. Granule loss on the south-facing planes, seal strips letting go at the eaves, or a flat-roof addition that ponds water every winter. Sycamore Contractors installs and services CertainTeed roofing, siding, and interior finish systems across all three Westminster ZIP codes (92683, 92684, 92685), and we’re an independent General Contractor – Westminster, not a CertainTeed dealer or authorized warranty arm. What makes our work here different comes down to one thing: we know this city’s Little Saigon housing and commercial fabric well enough to spot what a generic CertainTeed crew from outside the area would miss. Call (877) 265-6284 for a free estimate on any CertainTeed scope.
Why Westminster Residents Choose Us for CertainTeed Service
Our crews work on CertainTeed systems in Westminster every week, and we also provide Garden Grove CertainTeed service. Landmark tear-offs on Bolsa-area ranch homes, Cedar Impressions siding updates, Presidio tile details on newer remodels. We treat the CertainTeed installation guides like a spec book, not a suggestion. Nate Calloway, our owner, grew up in Temecula and spent the better part of two decades swinging hammers and running crews across Southwest Riverside County before bringing that same standard to Westminster’s older housing stock. He’ll tell you the same thing he tells every homeowner: “Do it right the first time, or you’ll do it twice in the July heat.” That applies as much to a Landmark PRO re-deck off Bolsa Avenue as it does to a low-slope Flintlastic membrane on a restaurant strip center.
We’re an independent contractor. That means we’re not pushed to sell you a warranty upgrade or a manufacturer package you don’t need. We use CertainTeed-branded starter, hip, ridge, and underlayment where the assembly calls for it, and quality aftermarket flashing and fasteners where the spec allows. A $40 piece of edge metal is not where a roof should be economized, and we don’t.

Common CertainTeed Construction Problems We Solve in Westminster
- Granulating Landmark shingles on south- and west-facing roof planes. Original Landmark shingles installed on 1950s – 70s ranch homes throughout Westminster have taken decades of dry-season UV. The south slope and west slope will be bare in patches while the north slope still looks intact. That’s why we never quote a whole roof from the driveway. We walk every plane.
- Flat and low-pitch roofs ponding behind original ranch additions. Those 1960s family rooms and enclosed patios built onto the back of Westminster ranch homes often have nearly flat roofs. Winter rain pools, pushes Flintlastic or built-up seams apart, and wicks under the flashing. The leak often shows up as a stucco crack, not a ceiling stain. Homeowners chase the wrong thing for months.
- Santa Ana wind lift and creased shingles from four-nail installs. Original installs on older Westminster decks frequently used a four-nail pattern. After a strong Santa Ana event, shingles lift and crease. The creases hide under tabs that still look sealed. Next rain, you’ve got a slow leak you can’t find.
- Low-slope membrane failure on Bolsa Avenue strip centers around kitchen exhaust penetrations. Restaurant tenant improvements on Westminster’s commercial corridors were often retrofitted without re-detailing the curb. Grease-laden exhaust and hood penetrations rot the membrane from the inside out. We’ll dig into this more below because it’s the most expensive surprise most building owners in this city hit.
- Interior finish scope creep during multigenerational remodels. Westminster has a lot of homes being modified for extended families. Large commercial-style cooking vents, second kitchens, shrine rooms. Every new penetration through a CertainTeed roof assembly needs to be detailed in the same system, not caulked and left. We coordinate that as one scope, not two contractors guessing at each other’s work.
CertainTeed Service in Westminster: What Local Conditions Mean for Your Equipment
Little Saigon’s restaurant-dense Bolsa Avenue strip centers were largely built in the 1950s and 1960s without grease interceptor capacity or venting sized for serious cooking. That is a Westminster-specific condition, not a generic Orange County one. A CertainTeed low-slope re-roof on those buildings almost always becomes a combined scope. New Flintlastic membrane, re-flashed exhaust curbs, and hood and vent upgrades coordinated with the tenant. A roofing-only bid on one of these buildings will miss the actual problem. We’ve seen out-of-town contractors quote a straight re-roof, discover the rotted curb mid-job, and leave the owner with a change order for ten grand and a tenant who can’t open for a week. We bid it right the first time because we know the building stock along Bolsa Avenue and Westminster Boulevard before we climb the ladder.
On a mid-century ranch off Bolsa Avenue near the Little Saigon core, our crew tore off two layers of failing Landmark shingles down to the original 1×6 skip sheathing, re-decked to plywood for a proper nailing surface, and installed a new Landmark PRO assembly with high-wind nailing and ember-resistant vents. At the same property, the back addition’s low-slope roof was ponding after winter rains. We re-flashed the roof-to-wall transition with Flintlastic and added crickets to move water to the scupper. The homeowner now has one consistent CertainTeed system across both roof types instead of a patched-together mix. That’s the difference between reading a spec sheet and knowing what a Westminster ranch actually does in the rain.
CertainTeed Models & Products We Service in Westminster
We install and repair the full CertainTeed roofing line: Landmark and Landmark PRO architectural shingles, Presidential Shake and Presidential T/L heavier profiles, and Flintlastic SA modified bitumen for low-slope and flat roof conditions common on Westminster’s older commercial buildings and residential additions. We also handle Cedar Impressions siding and Presidio and Summit tile profiles for exterior finish work. Our repair approach is straightforward: CertainTeed-branded accessory components (starters, hip and ridge, underlayment matched to the assembly) where the warranty and inspection details call for them, and quality aftermarket flashing and fasteners where the spec allows. We service all models through our CertainTeed sales & service arm, and we tell Westminster homeowners honestly when a spot repair buys two more winters and when a tear-off is the only honest answer on a 40-year-old deck.

AfterCertainTeed Service Pricing in Westminster
Roof work in Westminster follows the same market ranges we use across our Southern California service area, including our CertainTeed repair in Huntington Beach. What drives the number: deck condition (skip sheathing vs. plywood), roof pitch, number of layers being torn off, and whether low-slope sections need Flintlastic instead of shingles. Add a kitchen remodel and the scope changes, which is exactly why we quote line items, not lump sums. Here’s what you can expect.
| Scope | Typical Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Tile Roof Repair | $600 – $2,500 |
| Full Kitchen Remodeling | $14,000 – $45,000 |
| Small Kitchen Remodel | $9,000 – $20,000 |
| Cabinet Installation | $4,000 – $13,000 |
A free estimate means exactly that. We come out, walk the roof or the room, and hand you a written line-item quote with no change orders on scope we’ve already agreed to. Call (877) 265-6284 to set one up.

FAQs – CertainTeed Construction in Westminster
In most cases, no. Code allows a second layer in some conditions, but on Westminster’s aging decks the structural deck is usually the problem, not the shingles. Original 1×6 skip sheathing never gave the nails a consistent bed. We nearly always recommend tear-off and re-deck to plywood before a new Landmark or Landmark PRO goes down. Call (877) 265-6284 and we’ll tell you what your specific deck can handle, free.
Because the roof failure on those older Little Saigon strip centers is rarely just the membrane. Grease-laden kitchen exhaust penetrations and undersized hood curbs rot the roof-to-wall flashing from the inside. A proper fix means Flintlastic SA membrane, re-flashed curbs, and venting corrections done with the tenant, not around them. Call (877) 265-6284 for a combined roof and exhaust-detail estimate before you commit to a single-scope quote.
Westminster sits in a wildland-urban interface zone under California fire codes, and Santa Ana wind events push embers across roof assemblies. We install ember-resistant vents and follow CertainTeed’s high-wind nailing patterns on every Westminster roof, regardless of the specific zone designation. That is a code minimum in our book, not an upsell.
The roof-to-wall flashing and any penetration curb. Ponding water from winter rains finds the seams, and on Bolsa Avenue buildings the kitchen exhaust penetrations are the first thing to go. If you’re seeing a stucco crack or water staining at the parapet, the membrane at the curb is likely already compromised. Call (877) 265-6284 and we’ll pinpoint it before it becomes a tenant disruption.
It absolutely does. Every new roof penetration, from the big cooking vent to the second kitchen’s exhaust, needs to be detailed through the CertainTeed assembly with matching underlayment and flashing. We coordinate the roofing and kitchen remodeling as one scope so the penetrations go in once and get flashed correctly the first time. Call (877) 265-6284 for a combined estimate.
