CertainTeed Roofing in Westminster, CA | Weston Roof Repair
We provide independent CertainTeed roofing service across Westminster, from leak repairs on 1950s tract homes to full underlayment retrofits under clay tile roofs in Little Saigon. The thing that sets our CertainTeed work apart here is simple: we know how these materials age in Westminster’s marine layer, and we fix what’s actually failing, not what’s convenient to sell. That means real repairs when a repair is all you need. Call (833) 589-6925 to schedule an inspection.
Westminster’s housing stock runs heavy on mid-century tracts, and a lot of those roofs were originally built with CertainTeed materials that are now 40 to 60 years old. We work on them every week. From Landmark shingles on single-story ranchers off Westminster Boulevard to CertainTeed sales & service support on older tile installs, our crew handles the full range. We’re not affiliated with CertainTeed and we’re not a franchise. We’re an independent roofing company that happens to know this brand inside and out because Westminster keeps giving us opportunities to prove it.
Why Westminster Residents Choose Us for CertainTeed Service
Alan Pruett started Weston Roof Repair after years of watching homeowners get pushed into full replacements when a targeted fix would’ve solved the problem for another decade. That repair-first mindset shapes how we approach every CertainTeed roof we touch in Westminster. We’ll inspect it first. If a repair fixes it, that’s what we’ll tell you.
Our experience with CertainTeed materials comes from working them in coastal Orange County conditions that most inland roofers never deal with. Morning marine layer, north-facing moss growth, Santa Ana wind bursts that lift shingle tabs and shear nails. We see those failure modes constantly across Westminster service area neighborhoods, and we’ve learned which CertainTeed products handle them well and which ones need attention after 15 or 20 years. We work with CertainTeed among six other leading manufacturers, so our recommendations are based on what your roof needs, not what we happen to stock or what a supplier incentivizes this quarter. From a single damaged shingle to a full tear-off, the same team handles it start to finish.

Common CertainTeed Roofing Problems We Solve in Westminster
- Marine-layer granule loss and curling on Landmark shingles. Westminster sits about five miles from the coast, and that morning marine layer hangs over north-facing roof slopes far longer than it does inland. Landmark shingles on those slopes lose granules and start curling at the edges well before southern-facing sections show wear. We catch it early when we can, before the fiberglass mat is exposed and water gets into the decking.
- Santa Ana wind damage on Presidential Shake TL. Fall winds through Westminster can hit 40 to 60 mph on exposed hillside routes. Presidential Shake TL shingles are thick, but older installs with failing sealant strips get lifted, cracked, or completely torn off. We usually find sheared nails along the windward edges of roofs that face the Santa Ana corridor.
- Disintegrated tile underlayment under Little Saigon clay tile roofs. Homes along Bolsa Avenue and surrounding Little Saigon streets often have heavy clay tile roofs installed decades ago with CertainTeed underlayment that was never meant to last 50 years. Those membranes dry out, crack, and channel water into the house during winter rains. The tile looks fine from the curb, but the waterproofing underneath is gone.
- Blistered XT 25 shingles on 1950s-60s tract homes. The original CertainTeed XT 25 three-tab shingles on many older Westminster tracts have been through 60 summers of thermal cycling. Poor attic ventilation makes it worse. We regularly replace blistered and bald sections on these homes, often before the homeowner realizes the roof is actively degrading.
- Flashing failures around carport and flat-roof transitions. A lot of Westminster homes have carports or flat-roof additions tied into the main roof. The transition flashing where a CertainTeed sloped roof meets a flat section is a classic leak point, especially after decades of expansion and contraction in our temperature swings.
CertainTeed Service in Westminster: What Local Conditions Mean for Your Roof
If you live in the Little Saigon area along Bolsa Avenue, your clay tile roof is beautiful, heavy, and probably leaking from the underlayment rather than the tile itself. That’s the Westminster-specific insight most roofing pages miss. Many of these tile installs from the 1970s and 80s were set over thin organic felt or early CertainTeed membranes that have since dried into brittle fragments. The tiles themselves can last another 50 years, but the waterproofing beneath them is already gone. When winter rains arrive, water bypasses the cracked underlayment and finds the decking. Homeowners in these neighborhoods understandably want to keep their clay tiles – they’re part of the home’s character, and replacement costs are substantial. So the fix is a retrofit: we carefully lift the tiles, slide new CertainTeed tile underlayment underneath, and set everything back in place. It’s slow, detail-heavy work, and most crews won’t touch it because one wrong move cracks a tile that’s hard to match. We’ve done enough of these on Westminster homes to do it without a full tear-off, and that saves homeowners thousands while keeping the roof they actually want.
CertainTeed Models & Products We Service in Westminster
We service the CertainTeed product lines most common across Westminster’s housing stock, along with CertainTeed in Stanton and surrounding areas. Landmark Series architectural shingles show up on thousands of mid-century ranchers and newer builds alike. Presidential Shake TL covers a lot of the heavier, style-conscious homes. XT 25 three-tab shingles still sit on original 1950s and 60s tract roofs. Centennial Cedar shakes appear on some of the custom homes and remodels in the area.
On the parts side, we use CertainTeed OEM shingles, underlayments, and accessories whenever they’re available, which keeps warranty coverage intact where it matters. But we also stock aftermarket components that meet or exceed OEM specs for situations where a fast Westminster turnaround, or CertainTeed service in Fountain Valley, beats waiting on a manufacturer backorder. Our honest stance: repair CertainTeed roofs when the damage is localized and the decking underneath is sound. Recommend full replacement when failure is widespread or the roof has pushed past 20 years.

AfterCertainTeed Service Pricing in Westminster
Midway City CertainTeed service and Westminster pricing both vary by the scope of the job. Targeted shingle replacement on a Landmark roof typically runs between $350 and $900 depending on how many squares are compromised and whether we’re matching an active product line. Tile underlayment retrofits in Little Saigon generally land between $4,000 and $11,000 based on roof size, slope, and tile condition during lifting. Full roof replacement with CertainTeed Landmark shingles on an average Westminster tract home runs $14,000 to $26,000, with Presidential Shake TL running higher due to material and labor intensity.
Every estimate we give starts with an inspection. We walk the roof, document what we find, and write a line-item quote so you know exactly what you’re paying for before any work begins. Call (833) 589-6925 to schedule your free estimate.

FAQs – CertainTeed Roofing in Westminster
Yes. We retrofit underlayment by lifting sections of tile, sliding new CertainTeed membrane underneath, and resetting the tiles in place. This works on most Westminster tile roofs where the tile itself is still in solid shape. The process takes longer than a full tear-off and costs more per square foot, but it preserves the tiles you already own and avoids disposal fees. Call (833) 589-6925 to have us assess whether your tile roof qualifies for a retrofit rather than a full replacement.
Mostly, yes. The marine layer sits on north-facing slopes longer than any other part of the roof, and persistent moisture accelerates granule loss and curling even on architectural shingles like Landmark. Add in moss growth that traps water against the shingle surface, and you get premature deterioration that southern slopes never see. If the decking underneath is dry and the damage is concentrated, we repair the affected sections. If it’s spread across the entire slope, we’ll tell you replacement is the better call. Estimates are free at (833) 589-6925.
Presidential Shake TL shingles handle wind better than three-tab products, but no shingle survives a direct Santa Ana hit if the sealant strips have aged out. We see failures mostly on exposed hillside homes and the windward edges of roofs along open corridors. The shingles themselves often look fine, but the nails shear and sealant strips break. We inspect the whole roof after a Santa Ana event, not just the area where you noticed a missing shingle. Call (833) 589-6925 for a wind-damage inspection.
We use CertainTeed OEM shingles, underlayments, and accessories whenever they’re available for the repair you need. That keeps manufacturer warranty coverage intact on new materials. For situations where lead times would leave your Westminster roof exposed, we stock aftermarket components that meet or exceed OEM specs. We’ll never install a part that voids your warranty without telling you first. If you’re unsure what your CertainTeed warranty covers, call (833) 589-6925 and we’ll walk through it with you.
Start with a diagnosis, not a patch. A leak under tile usually means the underlayment has failed somewhere, and finding the actual entry point takes an experienced eye. Patching the visible spot without addressing the degraded membrane underneath just moves the leak to a new location. Call (833) 589-6925 to schedule a leak inspection, and we’ll trace the water path back to the real source before quoting you a fix.
