Why Los Angeles Homeowners Choose CertainTeed Construction
Elmstead Remodeling provides Certainteed service in Los Angeles as an independent construction company – roof replacement, roof repair, emergency storm response, and AirRenew drywall installation – with a written price before any work starts and a 365-Day Done Right Promise on every completed project. We work on Landmark, Presidential, and Symphony shingle systems plus AirRenew drywall, and we know how each one behaves under Los Angeles sun, Santa Ana wind, and coastal moisture. We are not authorized, sponsored, or endorsed by CertainTeed. We are an independent remodeling company that has spent years learning their products from the roof deck up. Call (949) 850-9896 for a free estimate.
What separates our CertainTeed work in Los Angeles is specificity. We name the exact shingle series, the exact failure mode, and the exact repair path before we pick up a tool. That matters in a city where LADBS permit queues stretch months and the difference between a $700 repair and a $14,000 replacement often comes down to whether someone actually walked the roof or just guessed from the curb.
Why Trust Elmstead Remodeling for Your CertainTeed Construction?
Graham Stein, our owner, learned framing and finish work at Los Angeles Trade-Technical College on South Grand Avenue, where instructors expected you to read a set of plans before you touched a tool. He has been working on Los Angeles homes for going on two decades, and the habit that stuck is the one his father modeled on weekends: fix things carefully, not quickly. That is the standard our CertainTeed crews work to.
Every technician who touches a CertainTeed roof for us has walked dozens of them across Los Angeles – from Sherman Oaks to Silver Lake to the hills above Studio City – and handled Certainteed repair in Glendale and surrounding neighborhoods – and can tell you the difference between normal granule settlement and the kind of granule loss that signals a shingle is aging out. We source genuine CertainTeed materials through authorized distributors so warranty coverage stays intact where it applies. For older or discontinued lines, we use aftermarket shingles and accessories that meet or exceed the same ASTM performance standards, and we tell you which path we are taking before we start. The written scope is the promise – if it is not on the paper, we have not agreed to it yet.
We also run a live-person phone line 24/7. When a Santa Ana wind event tears shingles off at 2 a.m., you get a person, not a voicemail.

Common CertainTeed Construction Problems We Fix in Los Angeles
- Granule loss on Landmark series shingles. Los Angeles UV exposure is brutal. On south-facing slopes we routinely see Landmark roofs losing protective granules after 12 to 15 years, which exposes the asphalt mat underneath and accelerates aging. The roof still sheds water, but it is absorbing more heat and aging faster than it should. Repair means replacing affected shingles before the underlying mat cracks.
- Cracking and splitting on Presidential series luxury shingles. Presidential shingles are thick and heavy, which makes them great in wind but vulnerable to thermal cycling. Los Angeles swings from 45-degree nights to 100-degree afternoons, and that repeated expansion and contraction can crack the shingle at the nail line. We see this most on poorly ventilated attics in the Valley, where heat builds up under the deck and bakes the shingles from below.
- Adhesive strip failure on Symphony solar-reflective shingles during Santa Ana winds. Symphony shingles carry a reflective granule coating that reduces heat absorption, but the self-sealing adhesive strip can lose its bond after repeated high-heat cycles. When Santa Ana winds hit with 60-mph gusts, shingles with weakened adhesive lift and tear. We see this in canyons and on ridgelines where wind gets funneled, and the fix is resealing or replacing shingles before the next wind event.
- Moisture damage behind AirRenew drywall in poorly ventilated bathrooms. AirRenew is designed to absorb formaldehyde and resist moisture, but it is not a substitute for proper ventilation. In Los Angeles bathrooms without exhaust fans or with undersized fans, steam penetrates the drywall and causes softening and mold behind the surface. We replace the damaged board, fix the ventilation issue, and re-install AirRenew or a moisture-rated alternative depending on the room.
- Ridge cap and flashing failures on all CertainTeed shingle lines. The shingles themselves are often fine; the ridge caps and flashing are what fail first. Los Angeles sun degrades the sealant at ridge caps, and thermal movement breaks the bond between flashing and shingle. Water follows the gap. We inspect these points first on any CertainTeed roof, because they fail years before the field shingles do.
CertainTeed Parts & Our Repair-vs-Replace Approach
We source genuine CertainTeed shingles and accessories through authorized distributors whenever the line is still in production and warranty coverage matters. A Landmark PRO shingle installed today matches the color and performance profile of the original Landmark line, which is important when we are repairing a 15-year-old roof in Sherman Oaks and the homeowner wants it to look like one roof, not a patch job.
For discontinued CertainTeed lines, we use high-quality aftermarket shingles that meet or exceed ASTM standards. We tell you which we are using and why. The repair-vs-replace call is made honestly: we recommend full replacement when repairs would compromise roof integrity or when repair costs exceed 30% of a new roof. Below that threshold, we repair. The homeowner always gets the numbers in writing before any work starts. Call (949) 850-9896 for a written repair-versus-replace assessment.
Our CertainTeed Service Process – Step by Step
- 1
Diagnosis. We walk the roof, not just the driveway. We check granule condition, adhesive strip integrity, ridge caps, flashing, and ventilation. For AirRenew drywall, we check for softness, staining, and moisture behind the surface. The diagnosis is written down with photos and specific measurements.
- 2
Written scope and price. Before any work starts, you get a written scope naming the exact CertainTeed products, quantities, and cost. No estimates that grow after the crew arrives. The written scope is the promise.
- 3
Repair or install. We use genuine CertainTeed materials where warranty compliance matters, and we protect the home the way we protect every home: drop cloths on floors, shoe covers at the door, quiet tools during family rest hours, and pet-safe product choices where there is a choice.
- 4
Test and clean. We run water tests on repaired flashing and seams where practical, check the roof for loose fasteners and leftover debris, and photograph the clean-up before the crew leaves. That photo is included on every job as proof the home was left right.
- 5
Warranty and follow-up. Every CertainTeed project is covered by our 365-Day Done Right Promise. If something is not done right after the job is complete, we make it right. Manufacturer warranties on CertainTeed materials remain in place where applicable.

FAQs – CertainTeed Construction Service in Los Angeles
If granule loss is limited to a few shingles or one slope, repair is usually the right call, typically $470 to $2,125 in Los Angeles depending on the number of shingles and access. If granules are missing across most of the roof, shingles are curling, or the roof is over 20 years old, replacement may be the better investment at $9,440 to $23,600. Call (949) 850-9896 for a written assessment and exact numbers.
Yes. For Landmark and Presidential roofs still in production, we source the exact color from authorized distributors. For older or discontinued colors, we match as closely as possible with an aftermarket equivalent and tell you before we install anything. The goal is a repair that looks like one roof, not an obvious patch.
The most common failure we see is adhesive strip breakdown from repeated high-heat cycles, which lets Santa Ana winds lift the shingle. The reflective coating itself holds up, but the seal underneath weakens. We reseal or replace affected shingles and check the entire slope, because once one shingle lifts, the next wind event will take more.
Yes. We respond to wind and rain damage across Los Angeles, including Certainteed in Anaheim, and our phones are answered by a live person 24/7. We tarp, patch, and secure the roof to stop water entry, then provide a written scope for permanent repair. Call (949) 850-9896 and a person will pick up.
AirRenew absorbs formaldehyde and handles moisture better than standard drywall, which matters in Los Angeles bathrooms that get daily steam. But it needs working ventilation to perform. We install AirRenew where ventilation is adequate, and we fix the ventilation first where it is not. Bathroom vanity installation near AirRenew walls typically ranges from $945 to $3,540 if you are already in the room.
No. We are an independent remodeling company. We source genuine CertainTeed materials through authorized distributors and follow CertainTeed installation guidelines, but we are not authorized, sponsored, or endorsed by CertainTeed. What you get from us is hands-on experience with their products across Los Angeles and a written price before any work starts.
