CertainTeed Roofing in Sherman Oaks, CA | Barnwood Roofing
We provide independent CertainTeed roofing service across Sherman Oaks, from roof inspections to targeted repairs and full replacements. The one thing that makes our CertainTeed work here different is simple: we know how these shingles behave after 15 years of San Fernando Valley sun, and we’ll tell you whether a repair will hold or a replacement makes more sense. Call (855) 382-1073 for a straight answer.
Why Sherman Oaks Residents Choose Us for CertainTeed Service
Most roofing companies can put a new roof on. Fewer can walk up to a 1980s tract home in Sherman Oaks, look at the south-facing slope, and tell you exactly what’s happening to those CertainTeed Landmark shingles before they even climb a ladder. That’s what we do. We also provide Roof Repair – Sherman Oaks homeowners can count on. Ruben Calloway, our owner, learned the trade through Chaffey College’s construction technology program and has spent years working roofs across the San Fernando Valley and the Inland Empire. He built Barnwood Roofing on a simple rule: inspect first, recommend second. We’re an independent CertainTeed service provider, not a manufacturer affiliate. That means we source across seven major brands including GAF, Owens Corning, IKO, Atlas, Tamko, and Boral alongside CertainTeed, so the product we recommend fits your home and budget, not our inventory.

Common CertainTeed Roofing Problems We Solve in Sherman Oaks
- Heat-driven granule loss on Landmark shingles. South- and west-facing slopes in Sherman Oaks absorb relentless afternoon sun, and CertainTeed Landmark shingles can lose their ceramic granules within 10 to 15 years. You’ll see bare patches and granules collecting in gutters. We call it what it is: normal aging accelerated by 100°F+ summers.
- Curled and cracked tabs from UV exposure. Asphalt shingles don’t just age, they bake. On flat-land ranch homes in the 91403 and 91423 ZIP codes, we routinely find tabs that have curled so badly they break off in the next wind event. Replacement of individual tabs works as a short-term fix, but whole-cluster curling usually means the roof is near the end.
- Santa Ana wind uplift on ridge caps and edges. Hillside streets south of Ventura Boulevard get hammered by fall wind events. CertainTeed ridge caps and edge shingles with weakened sealant lift and tear, leaving roofs exposed. We repair the damaged section and check the rest of the ridge line for adhesive failure.
- UV-degraded underlayment under Symphony tile. Here’s a Sherman Oaks classic: the tile on a 1970s hillside custom home looks fine from the neighbor’s deck, but water is getting through. The CertainTeed Symphony tile itself is intact; the underlayment underneath has been baking for 40 years and finally cracked. Tile doesn’t leak, underlayment does.
- Sudden failure of older three-tab organic shingles. Those original CertainTeed three-tab shingles on 1970s-80s tract homes have been sun-brittle for years. The rare heavy winter storm is when they fail: wind-driven rain pries up shingles that are too brittle to flex, and suddenly there’s water in the living room. We see this every winter across Sherman Oaks.
CertainTeed Service in Sherman Oaks: What Local Conditions Mean for Your Roof
Here’s something we’ve learned working the hillside streets south of Ventura Boulevard: roofs in this part of Sherman Oaks are often only visible from below or from a neighbor’s deck. You can’t see your own roof from the street, so curling shingles, missing tabs, and bare spots go unnoticed until water finds a way in. And because the 1970s-80s tract homes were built in clusters, entire blocks tend to need CertainTeed shingle replacement within a few years of each other. We recently completed our Roof Replacement in Sherman Oaks on a two-story home in the hills off Beverly Glen Terrace. The south-facing slope had severe granule loss and curled tabs from decades of unrelenting sun. We replaced the original underlayment, which had become brittle, and upgraded the chimney flashing. The homeowner had no idea anything was wrong until a stain appeared on the ceiling, and by then two neighbors were already asking us when their roofs were due. That’s the pattern in Sherman Oaks, and it’s why we tell homeowners: if your neighbors are getting roofs replaced, have yours inspected now. That’s what we offer as a standalone service, by the way. A roof inspection doesn’t come with a sales pitch attached. Ruben puts it plainly: tell me what the roof actually needs, then we’ll talk about what it costs.
CertainTeed Models & Products We Service in Sherman Oaks
We work on the CertainTeed product lines most common across Sherman Oaks. That includes Landmark architectural shingles, the heavy Presidential Shake line, the Symphony tile system, and the Presidio tile system. For repairs, we use genuine CertainTeed replacement shingles and accessories whenever available, because that keeps your warranty valid and the color match clean. When a line is discontinued or a color is no longer produced, we source high-quality aftermarket equivalents that meet or exceed OEM specifications. We’ll always tell you which route we’re taking and why. Sherman Oaks homes with flat or low-slope sections still need flat roof patches and flashing repairs, and those are core services for us, not afterthoughts. The right material for your roof, not just what we stock. For more on our CertainTeed depth across the area, see our CertainTeed sales & service page.

AfterCertainTeed Service Pricing in Sherman Oaks
What drives CertainTeed service pricing in Sherman Oaks is scope. A small repair, like replacing a few wind-damaged shingles or patching a flat section, lands in the low three figures. A full slope replacement on a 1,800-square-foot ranch home will run several thousand dollars, depending on the CertainTeed product line you choose. Tile systems like Presidio or Symphony cost more than Landmark, both for materials and labor. The free estimate we give you includes a written line-item breakdown, so you’ll see exactly where the money goes before any work starts. We pull permits, pass inspections, and stand behind our workmanship. Want an exact number? Call (855) 382-1073 for a free estimate.

FAQs – CertainTeed Roofing in Sherman Oaks
Sherman Oaks heat accelerates shingle aging dramatically. A CertainTeed Landmark shingle in Sherman Oaks will lose granules and curl far sooner than the same shingle would in a cooler coastal city. The 100°F+ summers and intense UV exposure bake the asphalt, breaking down the chemical bonds that keep the shingle flexible and adherent. Where a coastal Landmark roof might reach 20 years, a south-facing Sherman Oaks roof can show significant decline in 10 to 15. Call (855) 382-1073 if you’re seeing granules in your gutters; we’ll tell you honestly where your roof stands.
Because the tile is not the problem. Symmetry tile is dense concrete, it sheds water well. What fails on Sherman Oaks hillside homes is the underlayment beneath it. Forty years of heat degrades the felt or synthetic underlayment until it cracks, and water finds the crack every time. The tile looks perfect, the roof leaks. We see this pattern constantly on 1970s-80s custom homes in the foothills. We can replace the tile, inspect and replace the underlayment, and restore weather resistance without replacing the whole tile field. Call (855) 382-1073 for an inspection, especially before the next winter storm.
In most cases, repair is enough. A Santa Ana wind event typically damages a specific area: the ridge line, the edges, or the eaves where uplift pressure is highest. If the shingles that lifted and tore were still in good condition before the wind, a targeted repair with genuine CertainTeed shingles restores the roof’s integrity and appearance. If the roof was already sun-brittle and curling across the whole slope, repair would be a band-aid on a bigger problem, and we’ll tell you that directly. Inspection first, recommendation second. Call (855) 382-1073 and we’ll assess the actual damage.
CertainTeed’s Landmark and Presidential Shake lines both carry a Class A fire rating, the highest available for asphalt shingles. In the Sherman Oaks hills, where wildfire risk is a real factor, we recommend sticking with Class A-rated product, which is standard across CertainTeed’s architectural and premium lines. If you’re in a very high fire-severity zone, we can also discuss Class A-rated tile systems like Presidio or Symphony with proper underlayment. Call (855) 382-1073 and we’ll walk the roof with you and match the product to your fire zone and budget.
Look for three things: curling at the corners, bare spots where granules are gone, and shingles you can break with light pressure. If any two of those are present across a significant portion of the roof, replacement is the right call. Those original organic three-tab shingles are now 40 years old, and in Sherman Oaks they’ve been baking in Valley heat the entire time. When the next heavy winter storm hits, brittleness turns into failure. We can inspect the whole roof and give you an honest read. Call (855) 382-1073 for a free estimate and a no-pressure inspection.
