CertainTeed Roof Repair in Los Angeles: What to Know First
We provide independent CertainTeed roof repair in Los Angeles, and most calls are handled same-day or next-day with a crew that knows these shingles by sight. A typical repair runs $280-$750 depending on what’s failing, and we quote the full price before we start - the number on the estimate is the number on the invoice. This page is for homeowners in neighborhoods from Sherman Oaks to Silver Lake who know they’ve got CertainTeed on their roof and want it fixed by people who understand the product, not a crew that’s guessing. Call (844) 563-1816 and a live person will pick up, 24 hours a day.
How CertainTeed Products Fail - and How We Fix Them
- Landmark Solaris shingle cracking in the San Fernando Valley heat. These reflective shingles hold up well, but after 12-15 years the polymer-modified asphalt can develop thermal fatigue cracks along the exposure line, especially on west-facing pitches that bake from noon on. We remove the damaged courses, match the Solaris color lot from our supplier in Vernon when possible, and replace with full-tab shingles rather than face-sealing, which voids any remaining warranty coverage.
- Landmark Pro blow-offs in Santa Ana wind events. The laminated layers separate at the sealant strip when installation was done in cold weather or the shingles never got proper solar sealing time. We see this in the hills above Glendale and Pasadena after the first big Santa Ana. Our fix: strip the affected area, inspect for nail pattern compliance, and re-install with six-nail placement and hand-sealing in the field until ambient temperatures allow natural thermal adhesion.
- XT 25 three-tab granule loss on flat-pitch additions. This economy line was common on 1980s and 1990s ranch homes in the Valley, often installed on carports and patio covers with minimal slope. The mineral surfacing washes out prematurely when water ponds, exposing the asphalt core to UV. We don’t try to spot-patch these - the substrate is usually compromised. We strip to deck, install proper underlayment, and re-cover with a low-slope appropriate material, typically a self-adhering modified bitumen or a transition to CertainTeed’s Flintlastic if the homeowner wants brand consistency.
- Flintlastic SA system seam separation on commercial-flat conversions. Los Angeles has thousands of converted duplexes and small apartment buildings with these self-adhering modified bitumen membranes. The seams fail where foot traffic, HVAC service, or satellite dish installation stressed the lap joints. We cut back to sound adhesion, prep with Flintlastic primer, and re-weld with a compatible SBS-modified bitumen - never a generic tarp patch that’ll hold water and rot the deck.
- Ridge vent and accessory failures on Landmark TL installations. The triple-laminate weight puts more load on ridge caps and vents than standard shingles, and we’ve found the factory ridge vents sometimes separate at the nail flange after 8-10 years. We replace with CertainTeed’s Ridge Vent 3 or a quality aftermarket equivalent rated for the heavier shingle profile, and we always run a bead of sealant under the leading edge - it’s a five-minute step that prevents callbacks.
Our CertainTeed Roof Repair Process
- 1
Call and schedule. A live person answers, day or night. We ask what you’re seeing, when it started, and whether you know your shingle type. If you don’t, that’s fine - we’ll figure it out on the roof.
- 2
Photo-documented inspection. Our technician walks every square foot, photographs the failure, identifies the CertainTeed line and approximate age, and checks for secondary damage. You get the photos. No scary speech in the driveway.
- 3
Parts decision. We source OEM CertainTeed when the color lot is available and the warranty still matters. For discontinued lines or when lead time stretches past what’s reasonable, we use quality aftermarket equivalents that match the performance spec - and we tell you which we’re using and why.
- 4
The repair. We work to CertainTeed’s published installation guidelines, not a shortcut that saves us an hour. Flashing gets step-sealed. Nails hit the right zone. Underlayment laps properly.
- 5
Water test and cleanup. We run a hose on the repair when access and water pressure allow, or we schedule a return check after the next rain. Then we magnet-nail-sweep the perimeter and haul everything off.
- 6
The 90-Day Done Right Promise. Written, no paperwork runaround. If it’s not right, we come back and make it right.
What CertainTeed Roof Repair Costs in Los Angeles
These are real ranges from jobs we’ve done in Los Angeles County this past year:
| Repair Type | Typical Range |
|---|---|
| Shingle replacement (up to 3 squares, accessible pitch) | $280-$450 |
| Valley repair with new flashing | $550-$850 |
| Leak source repair (vent boot, pipe collar, small flashing) | $220-$380 |
| Flintlastic flat patch (up to 100 sq ft) | $650-$1,100 |
| Ridge vent replacement with cap shingles | $400-$650 |
What moves the price: roof pitch (steeper costs more for safety and time), access (a two-story in the Hollywood Hills takes longer than a single-story in Northridge), and how far the damage has spread before you called. We don’t know your exact number until we see it. Call (844) 563-1816 for a free estimate - no obligation, no pressure, and we’ll be there when we say.
Why Los Angeles Homeowners Call Ridgeline Roofing Co. for CertainTeed Work
We’ve been on Los Angeles roofs since 1984. Pete Navarro started this company because he’d watched too many homeowners get talked into work they didn’t need or left with a repair that failed before the next season. We’re not a storm-chasing outfit - we hire local crews, train apprentices into journeymen, and plan to be here in thirty years.
Our technicians know CertainTeed’s product lines because they’ve handled thousands of repairs across the San Fernando Valley, the Eastside, and the Westside. We’re also authorized installers of GAF, Owens Corning, and four other major brands, so when a CertainTeed line is discontinued or a color lot is exhausted, we can recommend a genuine equivalent without pushing you toward a full replacement you don’t need.
The 90-Day Done Right Promise means what it says. If it’s not right, we make it right - no forms to file, no arguments about whether the leak was “in the scope.” And a live person answers the phone at midnight on a Saturday when the Santa Anas are tearing through and your ridge cap just peeled back. That’s not a feature. It’s just how we work.
FAQs
No, if the repair is done by a qualified contractor following CertainTeed’s installation guidelines and using compatible materials. The warranty covers manufacturing defects, not installation errors - so the key is proper technique and documentation. We photograph our work and note the materials used, which protects your coverage if you ever need to file a claim. Call (844) 563-1816 if you want us to review your warranty status before we start.
Sometimes, but not always. CertainTeed has discontinued lines like the Presidential Shake TL original profile and some older Horizon variations. When OEM isn’t available, we source quality aftermarket shingles that match the thickness, exposure, and wind rating - or we discuss a targeted replacement zone that blends with your existing roof. We never leave you with a mismatched patch that announces itself from the street.
If the damage is isolated to one area, the shingles are less than 20 years old, and the underlayment is sound, repair is usually the right call. We recommend replacement when we’re seeing widespread granule loss, multiple leak points, or deck rot that indicates system failure. We’ll tell you straight which it is - we don’t profit from selling you a roof you don’t need. Our $89 Seasonal Tune-Up is a good way to catch this early.
Same day for most calls placed before 2 PM, next day for later calls or during major storm events. We keep CertainTeed-compatible materials in stock at our warehouse, so most repairs are completed in a single visit. If you’re catching water in a bucket right now, call (844) 563-1816 - a live person will answer and get you scheduled.
Yes, regularly. Flintlastic SA and FR systems are common on Los Angeles commercial-flat conversions and low-slope residential additions. The repair techniques differ from shingle work - heat-welding, proper priming, and seam detailing are critical. Our crews are trained on modified bitumen systems, and we carry the compatible primers and cap sheets to do it right without a return trip.
