Why Los Angeles Homeowners Choose CertainTeed Construction
Penhallow Remodeling Los Angeles provides independent CertainTeed construction service across Los Angeles, and we work on their roofing and siding systems every week. What sets our CertainTeed work apart is field-level knowledge of how Landmark™ shingles, Presidential Shake™, Symmetry™ Slate, and Cedar Impressions® behave after a decade of Los Angeles sun, Santa Ana winds, and marine layer moisture. We are not affiliated with or authorized by CertainTeed, and we won’t pretend otherwise. We’re an independent service provider whose crews know these products from tearing them off, repairing them, and reinstalling them across neighborhoods from Woodland Hills to Sherman Oaks. If you need CertainTeed service in Los Angeles, call (213) 277-6578 for a free estimate.
Why Trust Penhallow Remodeling Los Angeles for Your CertainTeed Construction?
Our crews open up CertainTeed roofs and siding in Los Angeles regularly, and that repetition matters. We know how Landmark shingles lose their seal strip on south-facing slopes after years of intense UV exposure. We know what Presidential Shake tabs do when a Santa Ana wind event hits a roof where someone drove nails too shallow. Trevor Nash, our owner, grew up in the Crenshaw district and studied construction technology at Los Angeles Trade-Technical College before spending nearly two decades on residential and light commercial jobs across the Basin. That background means he won’t guess. He’ll tell you what’s failing, why, and what it costs to fix before we touch anything. And every job we take gets a written price before work starts, a real arrival window, and our 365-Day Done Right Promise in writing. That’s the Kingswell standard we’ve followed since 2004. It’s not a phrase we put on a brochure. It’s how we run every CertainTeed repair and replacement we do in Los Angeles.
We also use CertainTeed’s specified accessories when the job calls for them, WinterGuard® at the eaves and DiamondDeck® underlayment where the system needs its original water-shedding performance. We don’t substitute generic materials where the manufacturer’s design relied on specific products. That’s not loyalty. It’s just how you keep a roof system performing the way it was tested.

Common CertainTeed Construction Problems We Fix in Los Angeles
CertainTeed makes solid products, but Los Angeles has a way of finding the weak points. Here are the five failure modes we see most often:
- Granule loss and curling on Landmark™ architectural shingles. After 15 to 18 years of direct Los Angeles sun, especially in high-UV neighborhoods like Woodland Hills, the asphalt starts breaking down. Granules wash into gutters. Shingle edges curl. The roof still sheds water, but it’s nearing the end. We inspect first and tell you honestly how much life is left before recommending replacement.
- Cracked or blown-off Presidential Shake™ tabs during Santa Ana wind events. Luxury shingles are heavy and thick, but they’re only as good as the fastening pattern. When the original installer drove nails too shallow or missed the nail line, the tabs lift. A good Santa Ana gust tears them off. We find this on 10- to 20-year-old Presidential Shake roofs all over the foothills.
- Hidden rot behind Cedar Impressions® polymer siding near the coast. This one surprises homeowners. The siding itself won’t rot, but moisture wicks behind it at butt joints in marine layer zones like Playa del Rey or Mar Vista, and the OSB sheathing behind it rots silently. By the time anyone sees a soft spot, the damage is several feet wide.
- Symmetry™ Slate tiles slid out of alignment on steep slopes. We see this on hillside homes in Silver Lake and Echo Park, where the roof pitch is aggressive. Original installers under-drove the nails, and over time the tiles creep. It looks catastrophic, but it’s often a localized fix rather than a full slope replacement.
- Failed seal strips on Landmark shingles leading to wind-driven rain leaks. The seal strip is the adhesive line that bonds each shingle to the one below it. After years of heat cycling, it fails. Shingles lift, wind pushes rain underneath, and the leak starts at the underlayment. This is one of the most common silent failures we find in Los Angeles.
CertainTeed Parts & Our Repair-vs-Replace Approach
We use CertainTeed’s specified parts wherever the system’s intended performance depends on them. That means WinterGuard® membrane at eaves and valleys, DiamondDeck® underlayment where the original design called for it, and color-matched Landmark or Presidential stock for repairs. We won’t push a full roof replacement when a localized fix, done cleanly and to code, solves the problem. A 6-foot section of failed Landmark shingles doesn’t require tearing off a 2,400-square-foot roof. But we’ll also tell you plainly when a repair is just buying time on a roof that’s already 18 years old and losing granules across every slope. The decision is yours. The job is ours to do right either way. Call (213) 277-6578 and we’ll inspect it and give you a written number for both options.
Our CertainTeed Service Process – Step by Step
Every CertainTeed job in Los Angeles follows the same sequence, and it’s not complicated:
- 1
Diagnosis. We inspect the roof or siding, identify the specific failure, and document it. For Landmark shingles, we check seal strip condition, granule retention, and nail pattern. For Cedar Impressions siding, we probe for hidden moisture behind butt joints before anything gets opened up.
- 2
Written quote. You receive a written price before any work starts. Not a range, not a verbal ballpark. The number on day one is the number on the invoice.
- 3
Repair or install. We use CertainTeed-specified materials, match color and profile, follow manufacturer fastening schedules, and pull a clean, uniform crew. A while back, our tech climbed a 1960s ranch in Sherman Oaks. The owner had a leak after a winter storm. We found the Landmark field shingles had lost their seal strip on the south-facing slope, letting wind-driven rain reach the underlayment. We removed the affected courses, replaced the deteriorated WinterGuard® at the eave, and reinstalled new Landmark shingles with six nails per tab. The leak hasn’t returned through two wet seasons.
- 4
Test and verify. We water-test the repair where practical, check every edge and seal, and walk you through what was done.
- 5
Warranty in writing. Every job gets our 365-Day Done Right Promise. If it fails inside the guarantee period, we come back and fix it at no charge. No service call, no re-inspection fee.

AfterCertainTeed Products We Service & Install in Los Angeles
Our crews handle the CertainTeed lines most common in Santa Monica Certainteed service and Los Angeles: Landmark™ architectural shingles, Presidential Shake™ luxury shingles, Symmetry™ Slate roofing, and Cedar Impressions® polymer siding. We also work on CertainTeed flashing components, ridge caps, and the underlayment systems these roofs were designed around. We keep common Landmark color stock and standard accessory materials accessible locally so repairs don’t stall waiting on a truck from out of state. When a job calls for a specific color or line we don’t have on hand, we source it through our supplier network and keep you informed of the lead time in writing before we start.
We Also Service These Brands
CertainTeed is a big part of what we do, but it’s not the only thing. We’re a full-service General Contractor services company in Los Angeles, and we work with KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, Kohler and Moen fixtures, James Hardie siding, and more. That matters because a roof leak often means water ended up somewhere else, in a ceiling, behind a cabinet, or under flooring. We can handle the whole path of the damage, not just the first layer.
FAQs – CertainTeed Construction Service in Los Angeles
Yes, we can usually match the color closely, and in most cases the patch is not obvious. CertainTeed Landmark colors are widely available in the Los Angeles supply chain. The caveat is weathering: a roof that’s 10 years old has faded from UV exposure. New shingles in the same color will look slightly different for the first season or two. On lower slopes or less visible roof sections, this rarely matters. On a prominent front slope, we’ll talk through whether a localized repair or a full slope replacement is the smarter call before you spend a dollar. Call (213) 277-6578 for an inspection and an honest answer.
Yes. Pre-2014 Presidential Shake installations are actually a large share of our CertainTeed repair work in Los Angeles. The older fastener recommendation allowed fewer nails per tab, and on steep or wind-exposed slopes, those tabs lift. We inspect the existing fastening pattern first, then replace damaged tabs using the current six-nail schedule, which holds far better during Santa Ana wind events. We won’t tell you the entire roof needs to come off unless the decking or underlayment has failed. If it’s just tabs, we fix tabs.
In most cases, yes. Symmetry Slate tiles that slide out of alignment are usually a fastening problem, not a product failure. We lift the affected tiles, reset them on the proper nail line, and re-secure them to manufacturer spec. If the underlayment below is intact and the tiles themselves aren’t cracked or broken, a localized repair is all it takes. On steep silver Lake or Echo Park hillside lots, we’ll also check that the original underlayment hasn’t torn under the loosened tiles, because that’s where water finds its way in.
Yes. Cedar Impressions polymer siding is tough, but pests get behind it the same way they get behind any siding. When that happens, we remove the affected panels, inspect the OSB sheathing and framing behind them, and repair whatever the termites or rodents damaged before reinstalling the siding, sometimes with new pieces where the old ones were chewed or warped. If the damage runs deep, we’ll tell you what the framing repair costs before we start. Nothing about that phase should surprise you.
Yes, and we do this in Los Angeles more often than people think. Ember fall from a nearby fire can damage shingles without leaving an obvious hole. We’ll tarp the affected section to stop any water intrusion, then inspect the full roof for ember damage, lifted tabs, and failed seal strips. A live person answers our phone 24/7, so you won’t get a voicemail maze at 9 p.m. on a red flag day. Call (213) 277-6578 and we’ll get a crew on the schedule. Roof repair and emergency storm damage work typically runs $470 to $2,125 in Los Angeles depending on the extent.
