CertainTeed Roof Replacement & Installation in Los Angeles: What to Know First
We provide independent CertainTeed roof replacement and installation in Los Angeles, with most full replacements completed in three to five days and repair calls typically handled same-day or next-day. Our pricing is upfront - the number on the estimate is the number on the invoice. We are not affiliated with or authorized by CertainTeed; we are an independent CertainTeed service provider that has worked on these systems across Los Angeles since 1984. This page is for homeowners who already have CertainTeed roofing and need honest guidance on whether to repair or replace, what it will cost, and who will stand behind the work. Call (844) 563-1816 - a live person answers, 24 hours a day.
How CertainTeed Products Fail - and How We Fix Them
- CertainTeed Landmark shingles - granular loss and premature bald spots. In Los Angeles, the combination of intense UV exposure and Santa Ana wind events accelerates granule shedding on Landmark architectural shingles, especially on south-facing slopes. We see this regularly in neighborhoods like Eagle Rock and Highland Park where roofs take a beating from the sun. Our fix: full tear-off to inspect the underlayment, then replacement with a heavier-weight shingle or upgraded ridge venting to reduce attic heat that cooks the new shingles from below.
- CertainTeed Presidential Shake - cracked tabs from thermal cycling. The thick, luxury-grade profile of Presidential Shake holds heat longer than standard laminates, and in the San Fernando Valley that daily expansion and contraction stress-crack the tabs after fifteen to twenty years. We replace these with fresh Presidential Shake only when the homeowner wants the exact look; otherwise we often recommend a lighter-profile alternative that handles our temperature swings better.
- CertainTeed XT 25 three-tab - blow-off and wind uplift. This economy line was common on tract homes built across the San Gabriel Valley in the 1990s and early 2000s. The sealant strip degrades faster in our dry heat, and once the Santa Anas hit, tabs lift and tear. We do not reinstall XT 25 on any full replacement; we upgrade to a laminate shingle with a stronger adhesive and proper six-nail fastening in wind zones.
- CertainTeed Flintlastic flat roofing - seam separation and ponding. On low-slope additions and ADUs common in older Los Angeles neighborhoods, Flintlastic SA self-adhered membranes can develop seam gaps where installation shortcuts left voids. Our fix: complete removal, proper slope correction with tapered insulation if needed, and reinstallation with full roller pressure and detail work at penetrations that most crews rush through.
- CertainTeed Cedar Impressions - color fading and moisture intrusion at butt joints. The polymer siding-shingle hybrid looks sharp when new, but in shaded, damp pockets of the Hollywood Hills and coastal-adjacent areas, moisture wicks behind panels at the joint overlaps. We replace compromised sections, add proper kick-out flashing, and never caulk over the problem - that just traps water.

Why Los Angeles Homeowners Call Ridgeline Roofing Co. for CertainTeed Work
We have been on Los Angeles roofs since 1984. Pete Navarro started this company because he was tired of watching homeowners get talked into work they did not need. Our 90-Day Done Right Promise means if it is not right, we make it right - no forms to mail, no phone tag. A live person answers every call, 24/7, including the night the wind tears off your ridge cap. Our technicians are background-checked, uniformed, and trained on CertainTeed’s specific fastening patterns and ventilation requirements. And because we also install GAF, Owens Corning, and four other manufacturer lines, we can recommend a different product when CertainTeed is not the best fit for your situation - no brand loyalty that puts our interests ahead of yours.
FAQs
No - provided the replacement is done with CertainTeed materials and follows their installation guidelines. As an independent CertainTeed service provider, we document our work with photos and product serial numbers so any future warranty claim has the paperwork it needs. Call (844) 563-1816 and we will walk you through what your existing warranty covers.
Most residential replacements take three to five days, weather permitting. In Los Angeles, rain delays are rare but Santa Ana wind events can pause work for safety. We protect your home with tarps at the end of each day and never leave a roof open overnight. Call (844) 563-1816 to check current scheduling.
If your CertainTeed roof is under fifteen years old and the damage is isolated, repair usually makes sense. Past twenty years, or if you are seeing multiple failure points across different slopes, replacement is typically the better use of your money - patchwork on an aging system often costs more over five years than doing it once, done right. We will give you an honest assessment either way; call (844) 563-1816 for a free inspection.
CertainTeed discontinues colors periodically, and UV fading means a new shingle will never match a fifteen-year-old roof exactly. We keep sample boards on the truck and will show you the closest current match before you commit. On partial repairs, we often recommend replacing an entire slope for a cleaner appearance. Call (844) 563-1816 to see your options.
Yes. A live person answers our phones 24 hours a day, seven days a week, including holidays and storm nights. For active leaks, we dispatch a technician to tarp and stabilize, then schedule permanent repair. Call (844) 563-1816 - we will be there when we say.
A roof doesn’t lie - it just waits until the rain to tell you the truth. We have learned that over four decades of working on Los Angeles homes, and it is why we do not cut corners on flashing, underlayment, or the details that keep water out. If your CertainTeed roof is showing its age, call (844) 563-1816. We will give you a straight answer, a fair price, and a job done right - or we will make it right.
