CertainTeed Construction in Sherman Oaks, CA | Mason Remodeling Co Woodland Hills
As a Sherman Oaks General Contractor and independent CertainTeed service provider, the short answer is this: we fix and replace CertainTeed siding, roofing, and underlayment with OEM parts where they matter, and we price the work in writing before anything begins. The thing that makes our CertainTeed work different here is that we’ve spent years learning how Valley heat and post-Northridge foundation shifts actually break these products. Cedar Impressions panels don’t fail the same way on a flat Sherman Oaks lot as they do on a hillside street near Mulholland Drive, and we plan repairs accordingly.

Why Sherman Oaks Residents Choose Us for CertainTeed Service
We’ve handled CertainTeed product lines for years, so we know the difference between a Cedar Impressions panel that can be re-secured and one that’s heat-warped beyond saving. That matters in Sherman Oaks, where the housing stock runs heavy on 1940s-1960s ranch homes and a growing number of stucco-box remodels-many tied to Bathroom Remodeling - Sherman Oaks projects on hillside and canyon-edge lots. When a homeowner calls about cracked Monogram siding or granule loss on Landmark shingles, we already know which failure pattern to look for before we arrive.
Isaac Pruett grew up in Los Angeles and trained at Los Angeles Trade-Technical College, then spent years working across the Valley, including long stretches near Warner Center. That means when we walk a Sherman Oaks roof or inspect a siding run, we’re looking at it the way a builder does, not the way a sales rep does. We’ll tell you what’s still sound, what needs repair, and what should be replaced. The price you get is written, and it doesn’t change once work starts.
Every technician who arrives at your Sherman Oaks home is background-checked, identity-verified, in a clean marked uniform, and carrying a photo ID badge. We send you their name and photo before the visit. That’s the Threshold Standard, and it’s how we’ve operated since 2004.

Common CertainTeed Construction Problems We Solve in Sherman Oaks
- Cedar Impressions polymer shake warping on west-facing gables. When Santa Ana winds push surface temperatures past 120°F, vinyl-and-polymer panels without proper expansion gaps buckle and pull away from the wall plane. Sherman Oaks’ hot, dry summers make this one of the most common siding failures we repair.
- DiamondDeck underlayment losing its slip-resistant coating. On steep hillside roofs, especially near Mulholland Drive, older DiamondDeck degrades and becomes slick. That’s a genuine fall hazard during winter re-roofs, and we flag it any time we walk a roof with that product installed.
- Landmark shingle granule loss on unvented 1940s ranch attics. The Valley heat cooks shingles from both sides when attic ventilation is poor. We regularly see Landmark roofs under 15 years old with heavy granule shedding and exposed fiberglass mat on original Sherman Oaks ranches.
- Monogram vinyl siding cracking at butt joints. On hillside and canyon-edge lots where post-Northridge foundation movement continues to shift wall planes, siding seams pop and panels crack. The 1994 Northridge earthquake epicenter was just a few miles from Sherman Oaks, and some homes still haven’t fully settled.
- Roof-to-wall transition leaks on mid-century additions. Sherman Oaks has a lot of 1950s and 1960s homes with second-story additions. Where stucco separates from the original roofline, underlayment tears and water gets in. We’ve fixed this exact failure pattern on multiple CertainTeed roofs in the neighborhood.
CertainTeed Service in Sherman Oaks: What Local Conditions Mean for Your Equipment
Here’s something a homeowner in Woodland Hills or Brentwood might not face the same way: Sherman Oaks sits inside a state-mapped liquefaction and earthquake-induced landslide zone. That’s not a footnote. The 1994 Northridge quake, with its epicenter a few miles away, fundamentally changed how buildings move here, and many mid-century homes still carry unretrofitted cripple walls and bolted-down deficiencies that inspectors flag constantly. When the ground shifts even a fraction of an inch, the load path changes. Walls move. Roof planes twist. And CertainTeed products, as well-made as they are, weren’t engineered to absorb that movement indefinitely.
So when we see popped Cedar Impressions seams or cracked tile underlayment on a Sherman Oaks hillside lot, we don’t just patch the surface. We check what’s underneath. On streets near Mulholland Drive, caisson and grade-beam foundations are common, and the local building department requires hillside grading and retaining wall permits that flatland projects never encounter. That means a simple siding repair on a hillside home may need more than a color-matched panel. It may need a foundation assessment first, because if the wall plane is still moving, new siding will fail the same way in two years. We’re the only CertainTeed service provider in the area that approaches these failures from the structure up, not the surface down.
CertainTeed Models & Products We Service in Sherman Oaks
We work across the CertainTeed lines most common on Sherman Oaks homes: Cedar Impressions polymer shake siding, Monogram vinyl siding, DiamondDeck synthetic underlayment, and Landmark asphalt shingles. When a repair needs color match and profile continuity, we source OEM CertainTeed parts. For Cedar Impressions and Monogram especially, aftermarket panels rarely match the original color after years of Valley sun, so we don’t bother trying. For flashing, fasteners, and underlayment, we use quality aftermarket material when it outperforms the stock spec. Our relationship with CertainTeed sales & service channels gives us access to the parts most supply houses in the San Fernando Valley don’t stock, which means faster turnaround for Sherman Oaks repairs.
If a product’s been discontinued or a repair would cost more than 60% of replacement, we’ll tell you straight and recommend full replacement. Patching a failing product is a short-term fix, and we’d rather give you a roof or siding run that lasts.

What drives the cost: roof size and pitch, number of roof-to-wall transitions, whether we’re removing failed DiamondDeck versus going over it, and whether the project needs hillside grading or retaining wall permits. A hillside roof near Mulholland with multiple additions will run higher than a simple single-story ranch on a flat Sherman Oaks lot.

FAQs – CertainTeed Construction in Sherman Oaks
In most cases, yes. We source OEM Cedar Impressions panels from CertainTeed’s current color line, and for discontinued profiles we work with suppliers who carry remaining inventory. After 50 years of Valley sun, the original color has faded, so a fresh panel won’t match perfectly. We can either tint-blend to approximate or recommend replacing the full wall face if you want a seamless look. Call (831) 290-6866 for an exact quote.
Landmark shingles hold up reasonably well in Sherman Oaks, but attic ventilation matters more than shingle brand. On unvented 1940s ranch attics, we’ve seen Landmark roofs lose granules in under 15 years. If you’re replacing a roof here, we’ll insist on proper intake and exhaust ventilation as part of the job. Landmark Pro or a heavier Architectural shingle is what we typically recommend for Sherman Oaks’ heat profile.
Most DiamondDeck failures we see in Sherman Oaks come from one of two causes: UV exposure where flashing gaps let sunlight hit the underlayment, or movement at roof-to-wall transitions where post-Northridge settling pulls the membrane apart. If your roof has a stucco-addition interface that’s shifted, the underlayment fails at that seam first. We inspect the whole transition and fix the structural cause, not just the tear.
No roof product, CertainTeed or otherwise, is earthquake-proof, and a repair won’t anchor a home that has unretrofitted cripple walls. What we do is make sure the roof and siding systems have enough movement tolerance at transitions and expansion joints to handle the settling Sherman Oaks experiences between major quakes. If your foundation hasn’t been retrofitted, we’ll tell you that too, because it directly affects how long any roof or siding repair will last. Call (831) 290-6866 and we’ll walk your roof with you.
In many cases, yes. Sherman Oaks hillside lots, especially near Mulholland Drive, fall under L.A. Department of Building and Safety hillside grading and retaining wall regulations that flatland homes don’t face. If your siding repair is tied to a foundation or drainage issue, you may need additional permits. We pull permits and handle inspections for every job that requires them, and the cost is included in your written estimate. Call (831) 290-6866 and we’ll tell you exactly what your hillside project needs.

We were called to a 1958 ranch on Valley Vista Boulevard after the owner saw water staining below a second-story addition. The Landmark shingles on the original roof were shedding granules, and DiamondDeck underlayment had torn at the roof-to-wall transition where the addition’s stucco had separated. We stripped the failing section, installed CertainTeed WinterGuard ice-and-water shield at the transition, and re-shingled with matching Landmark Pro. No more leaks, and no full roof needed for another five years.
That’s the kind of repair we do every week in Sherman Oaks. Isaac’s approach hasn’t changed: “Tell me what you need done. I’ll tell you what it takes and what it costs. Then we get to work.”
