CertainTeed Roofing in Sherman Oaks, CA | Van Nuys Roofing Co
We provide independent CertainTeed roofing service across Sherman Oaks, CA, working on Landmark architectural shingles, XT three-tab, Presidential Shake, and Flintlastic low-slope systems. For homeowners needing Roof Repair – Sherman Oaks, we diagnose heat and sun damage that generic contractors often miss. What makes our CertainTeed work different here comes down to one simple fact: Sherman Oaks roofs fail from heat and sun, not rain and ice. If you’ve got a CertainTeed roof showing wear, call (866) 321-6172 and we’ll tell you what’s actually going on up there.
We’re Van Nuys Roofing Co, and we’ve spent the better part of two decades on rooftops across the San Fernando Valley. Rick Dominguez started this company after years of watching contractors push whatever brand paid the best rebate that month. We don’t work that way. As an independent contractor, we quote CertainTeed on its merits and nothing else. No factory authorization. No brand loyalty that blinds us to what your roof actually needs. CertainTeed sales & service is one part of what we do, and we know the product line well enough to know exactly where it shines in Sherman Oaks and where it needs a little help from the sun it lives under.

Why Sherman Oaks Residents Choose Us for CertainTeed Service
We’ve stripped and re-roofed hundreds of CertainTeed installations across the San Fernando Valley. Landmark shingles on ranch homes. Flintlastic cap sheets on boulevard apartment flat roofs. Presidential Shake on custom hillside properties. We know how these products actually age under Valley sun because we’ve watched it happen, year after year, roof after roof.
Rick Dominguez grew up off Sepulveda Boulevard, a few blocks from the old Van Nuys Municipal Airport. He learned the trade through the construction technology program at Los Angeles Valley College over in Valley Glen, then spent years on rooftops before starting this operation. His dad was a finish carpenter, so working with his hands was never a question. Roofing stuck. That’s the perspective we bring to every Sherman Oaks service area job, whether it’s a small patch or a full tear-off.
Our approach is simple: we inspect first, recommend second. If it doesn’t need replacing, we’re not going to tell you it does. Sherman Oaks homeowners call us because they want a straight answer about their CertainTeed roof, not a sales pitch dressed up as a roof inspection.

Common CertainTeed Roofing Problems We Solve in Sherman Oaks
- Brittle, cracked Landmark shingles on west-facing slopes. Sherman Oaks homes take brutal afternoon sun, and certain Landmark shingle tabs on south- and west-facing planes go brittle and crack from year-round UV and 90°F+ heat cycling long before any granule loss suggests replacement. The roof can look fine from the street while the ridge-side tabs are ready to snap.
- Dried-out Flintlastic cap sheets on garage and addition flat roofs. This is the most common CertainTeed issue we see in Sherman Oaks. Flintlastic and other modified-bitumen cap sheets over garage and addition flat roofs dry out, alligator, and split at the seams where thermal movement concentrates. The Valley heat cooks them, and they crack before they wear out.
- XT three-tab shingles losing their seal-down strips. On 1950s – 60s ranch roofs across Sherman Oaks, CertainTeed XT three-tab shingles lose their seal-down adhesive in the heat. The tabs lift, and the first Santa Ana wind event tears them right off. It looks like wind damage. It’s heat damage that the wind just finished.
- Dried-out pipe boots and valley flashings. Paired with CertainTeed shingle systems, the rubber pipe boots and metal valley flashings on Sherman Oaks roofs crack and separate during the first heavy winter rain. Water tracks under field shingles that look completely intact. We’ve seen entire roof replacements recommended for what was actually a $40 pipe boot.
- Alligator-cracked modified bitumen on low-slope sections. Sherman Oaks ranch homes and garage additions carry a lot of low-slope CertainTeed cap-sheet and rolled roofing rather than steep architectural composite. Most calls we get are membrane and coating failures from sun baking, not missing shingles.
CertainTeed Service in Sherman Oaks: What Local Conditions Mean for Your Roof
Here’s what you need to understand about Sherman Oaks and CertainTeed roofs: this city sits in the San Fernando Valley’s hot inland basin, south of the Santa Monica Mountains, where summer roof-surface temperatures routinely push well past ambient and the sun hits hard year-round. Roofing in Sherman Oaks is fundamentally a heat-and-sun-damage business, not a freeze-thaw or storm-damage one.
That means your CertainTeed roof isn’t failing the way it would in Minneapolis or even Pasadena. The late-afternoon sun side of a low roof over a garage addition can be too hot to walk on bare-handed in summer, and that heat is doing something specific to the membrane every single day. The older ranch homes here, the ones built in the 1940s – 60s, carry flat-roof sections that bake and dry out until the modified bitumen develops hairline cracks that eventually open into channels for the winter rains. Thermal cycling does the damage; the rain just exposes it.
For CertainTeed owners specifically, this means Landmark and Presidential shingles on the south- and west-facing planes will show UV-driven brittleness and cracking before the granules wear away. It means Flintlastic cap sheets will alligator and split at the seams where thermal movement concentrates. It means your roof ages differently in Sherman Oaks than it does three miles over the hill. We plan our CertainTeed repairs around that reality, not around a generic industry lifespan chart.
CertainTeed Models & Products We Service in Sherman Oaks
We work on the full CertainTeed roofing lineup across Sherman Oaks: Landmark architectural asphalt shingles, XT 25 and XT 30 three-tab shingles, Flintlastic modified bitumen low-slope membranes, and Presidential Shake luxury shingles. When the system matters, we pair CertainTeed shingles with CertainTeed accessory components: matching ridge caps, starter strips, and underlayment. When it doesn’t matter, we don’t waste your money.
Take pipe boots and valley flashings, for example. CertainTeed doesn’t manufacture these third-party components, and the aftermarket options often outperform in Valley heat. We stock proven aftermarket boots and flashings for fast Sherman Oaks turnaround, and we use them where the OEM part adds no benefit under this sun. Where OEM matters, we match exact product lines so your repair integrates cleanly with the existing roof.

AfterCertainTeed Service Pricing in Sherman Oaks
CertainTeed roofing service in Sherman Oaks comes down to what’s actually wrong and how far the heat damage has spread. A simple shingle replacement. A flat roof patch. A flashing repair. Each job is different, and we price the work, not the neighborhood.
What drives the cost: the size of the affected area, whether we’re patching or tearing off, and whether the deck beneath is sound or delaminated. On a dried-out Flintlastic low roof, we patch and recoat when the deck is sound, and only recommend a full tear-off when the membrane has lost its core bond or the deck itself has started separating. That’s the honest line, and it’s the line we draw on every estimate.
A free estimate from us means we get up on the roof, look at what’s actually happening with your CertainTeed materials, and give you numbers for exactly what needs doing. No pressure. Call (866) 321-6172 for an exact quote. Estimates are free.

FAQs – CertainTeed Roofing in Sherman Oaks
In most Sherman Oaks cases, alligator cracking on a Flintlastic or modified bitumen cap sheet can be patched and recoated if the deck underneath is still sound. We cut out failed membrane sections, re-seal the seams, and recoat the low roof. Full tear-off only makes sense when the membrane has lost its core bond or the wood deck has delaminated. We’ll tell you which one you’re looking at after we inspect it. Call (866) 321-6172 for a free estimate.
That’s classic Sherman Oaks UV and heat cycling damage. The west-facing planes take the most intense late-afternoon sun, and Landmark shingle tabs go brittle and crack from thermal expansion and contraction long before the granules wear away. The street-facing slope protects itself from the worst of it. The damage is real, and it spreads if left alone.
Yes, when the system matters. We match CertainTeed shingles with CertainTeed accessory components on ridge lines, starter courses, and underlayment so the manufacturer warranty remains intact and the system performs as designed. Where third-party components outperform in Valley heat, we use those instead and tell you why.
Usually neither. In Sherman Oaks, we see XT three-tab shingles lose their seal-down adhesive from years of heat exposure. The tabs lift, and when the Santa Ana winds come through, they tear off. It’s a heat-driven failure that wind finishes. We can match the XT product line and repair the affected areas properly.
Recoating makes sense if the underlying membrane has simply dried out but still holds its core bond. A coating restores UV protection and buys you real years on a sound deck. If the cap sheet has alligatored through to the reinforcement layer, recoating won’t do much, and we’d rather tell you that up front than sell you a coating that fails. Call (866) 321-6172 and we’ll look at your exact roof before recommending anything.
