CertainTeed Roofing in Westminster, CA | Windmill Roof Repair
We provide independent CertainTeed roofing service across Westminster, CA, from shingle replacement and leak repair to full tear-offs, with CertainTeed repair in Huntington Beach also available nearby. What makes our CertainTeed work here different is simple: we know how these shingles actually behave on the 1950s-70s tract homes and Bolsa Ave commercial roofs that define this city. We’re not a CertainTeed dealer, and we’re not tied to any single manufacturer. If you’re dealing with a failing CertainTeed roof in Westminster, call (866) 850-2496 for a straight assessment.
Ruben Ochoa, our owner, grew up in Pico Rivera and learned roofing through the construction technology program at East Los Angeles College. He’s spent more than two decades on roofs across southeast LA County, the San Gabriel Valley, and Garden Grove CertainTeed service areas. His approach hasn’t changed: tell the homeowner what actually needs fixing and what can wait. That’s how we handle every CertainTeed roof we inspect in Westminster.
Why Westminster Residents Choose Us for CertainTeed Service
Most roofing companies in Westminster either push one brand or treat every shingle the same. We don’t do either. We work with seven leading shingle brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – so when we recommend a CertainTeed repair or replacement, it’s because the roof genuinely calls for it. Not because a distributor offered us a better margin this quarter.
That matters in Westminster, where the housing stock is heavy with 1950s-60s ranch homes that have been re-roofed two or three times over. We’ve torn off more layered CertainTeed XT 25 and Landmark roofs off Brookhurst and Bolsa than we can count. When a Westminster homeowner calls us about a leak, we can usually tell them what’s under the top layer before we even climb the ladder.
We carry CertainTeed OEM accessories – Ridge Vent, Shadow Ridge hip and ridge caps – and we match shingle lines exactly when the product is still available. For discontinued lines, we source quality aftermarket shingles that meet or exceed the original spec. You get a real answer about whether a repair will hold or whether it’s time for a tear-off. That’s the whole job.
As an independent contractor, we’re not authorized by CertainTeed. We’re honest about that. It means our recommendations aren’t shaped by a manufacturer agreement. It also means we’ll tell you when a different brand fits your Westminster roof better. Seven brands, one crew.

Common CertainTeed Roofing Problems We Solve in Westminster
- Algae streaking and mildew on Landmark shingles. The coastal marine layer that sits over Westminster in spring and early summer keeps north-facing slopes damp well into the afternoon. Landmark shingles without copper-infused granules develop dark streaks that homeowners often mistake for roof failure. It’s usually cosmetic, but we’ll confirm what’s happening and clean or treat it properly.
- Wind-lifted tabs on aged XT 25 3-tab roofs. Santa Ana wind events in the fall hit low-pitch gable ends hard. On XT 25 roofs that are 20-plus years old, the adhesive strip has often dried out, and a strong Santa Ana will peel tabs right off. We see this concentrated in the older tracts west of Beach Blvd and north of the 405.
- Premature granule loss and blistering on Presidential shingles. Presidential is a heavy architectural shingle, but it needs ventilation. Many Westminster homes got a DIY re-roof where the homeowner laid new shingles over old ones and never upgraded the attic ventilation. The heat that builds up under those layered roofs bakes the shingle from below. Granule loss follows within a few years.
- Flashing failures at flat additions and patio covers. This is the Westminster signature problem. Unpermitted flat patio covers and room additions were bolted onto tract homes decades ago, and the transition flashings were almost always done wrong. Water gets in at the transition and travels, showing up as a leak that looks like a shingle failure. It’s not. It’s the flashing.
- Layered tear-off complications on three-deep roofs. A significant number of Westminster homes have three layers of asphalt shingles piled on. That’s a lot of dead weight on a 1960s roof deck. When we’re called for a replacement, the estimate is driven by tear-off weight, deck condition, and transition work – not just the cost of the new shingles.
CertainTeed Service in Westminster: What Local Conditions Mean for Your Equipment
On the Bolsa Ave corridor and the older tracts off Brookhurst, we routinely find three-layer asphalt roofs with unpermitted flat additions and patio covers bolted onto the rear of the house. That combination changes everything about a CertainTeed re-roof estimate. Tear-off weight alone can run two to three times higher than a single-layer removal, and the deck underneath is often a patchwork of rotted sheathing that previous owners just shingled over. The transition flashings – where the flat patio roof meets the pitched shingle roof – are where the real leaks live.
For a Westminster homeowner with CertainTeed shingles, this means your roof estimate isn’t just about shingle cost per square. It’s about what’s under the shingles and what’s bolted onto the house. We recently re-roofed a 1962 ranch off Brookhurst near Bolsa where the original CertainTeed XT 25 shingles had been layered over twice, and an unpermitted flat patio cover had pulled away from the house, tearing the step flashing. After tearing off three layers and replacing the rotted decking, we installed CertainTeed Landmark in a charcoal blend and rebuilt the transition with new flashing and a modified-bitumen base. The homeowner said it was the first time in years the patio didn’t leak during a morning drizzle. That’s what we mean when we say Westminster roof work is about transitions, not just shingles.
A roof doesn’t have to be complicated – it just has to keep the water out. But in Westminster, the water has been getting in for decades through bad transitions and tired decking. Fixing that properly is the job.
Our CertainTeed sales & service experience across this area means we know what to expect when we tear into these roofs. If you’re in the 92683, 92684, or 92685 ZIP codes, this is what we see, and we plan for it before we start the tear-off.
CertainTeed Models & Products We Service in Westminster
We service the full range of CertainTeed residential shingle lines that were installed on Westminster homes over the past 40 years. That includes Landmark, Presidential Shake, Carriage House, and the older XT 25 3-tab that shows up constantly on original 1950s-60s tract roofs. We also handle the accessories: Ridge Vent, Shadow Ridge hip and ridge caps, and CertainTeed underlayments.
When we repair a CertainTeed roof, we use OEM accessories wherever the product line is still active. For discontinued lines like the original XT 25, we source quality aftermarket shingles that match the color and weight profile as closely as possible. We’ll show you the match before we install it. That’s standard practice for us – you see it before you sign anything. Our local parts relationships across the Westminster area mean we can get most CertainTeed material turned around quickly without waiting on a regional distributor to ship from out of state.

AfterCertainTeed Service Pricing in Westminster
CertainTeed roof work in Westminster is priced around a few specific factors. A targeted shingle repair on a Landmark roof might run a few hundred dollars depending on the number of tabs and access. A full tear-off and re-roof with Landmark or Presidential on a typical 1,400-square-foot Westminster ranch is a bigger number, driven by the tear-off weight. If you’ve got two or three layers and an unpermitted flat addition, that number climbs. It should – the labor to tear off three layers and rebuild transitions is real.
Every estimate we give in Westminster is free and includes a written line-item breakdown. You’ll see the shingle cost, the tear-off cost, the decking replacement allowance, and the flashing work as separate items. No change orders when we find bad decking – we allow for it up front based on what we already know about your neighborhood’s housing stock. Call (866) 850-2496 to schedule your free estimate.

FAQs – CertainTeed Roofing in Westminster
It’s almost always algae, especially on north-facing slopes in Westminster where the morning marine layer keeps shingles damp until midday. Landmark shingles without copper-infused granules are prone to this in our coastal-inland climate. It’s cosmetic in most cases and doesn’t affect waterproofing. We can clean and treat it, and if you’re re-roofing, we’ll point you toward CertainTeed lines with algae-resistant granules. Call (866) 850-2496 if you want us to take a look.
Yes. We replace wind-lifted or missing Presidential tabs regularly in Westminster after fall Santa Ana events. The key is matching the color and the profile correctly, and we stock the common blends locally so we’re not waiting on a special order. The repair cost depends on how many tabs are affected and where they are on the roof. Call (866) 850-2496 for a free estimate – we’ll give you the exact number before any work starts.
Yes, and this is one of the most common jobs we do in Westminster. The transition between a flat patio cover and a pitched shingle roof is where most leaks originate, and most of those transitions were built without proper step flashing. We rebuild the transition with correct flashing and a modified-bitumen base on the flat section. Whether the patio cover itself needs a permit depends on the scope, and we’ll talk you through that honestly. Call (866) 850-2496 to have us assess the transition.
You can’t always tell from the ground, but if your Westminster home is from the 1950s or 60s and the roof has been re-roofed twice, you likely have three layers. We confirm by lifting a shingle at the eave and looking at the cross-section. Most Westminster homes with three layers are past the point where another overlay makes sense – the weight is too high and the deck usually needs attention. We’ll show you what we find before you sign anything. Estimates are free at (866) 850-2496.
We install CertainTeed Landmark and Presidential shingles that carry the manufacturer’s warranty, and we follow CertainTeed’s installation specs so the warranty holds up if you ever need to file a claim. As an independent contractor, we can’t process warranty claims on CertainTeed’s behalf, but we’ll give you the documentation you need and help you through the process. Call (866) 850-2496 if you want a warranty-eligible CertainTeed quote for your Westminster home.
