Owens Corning Roofing in Ventura, CA | Crestview Roofing Co Ventura
We provide independent Owens Corning roofing service across Ventura, from tear-offs and Ventura Roof Replacement to flashing and leak repair on Duration, Oakridge, and Supreme shingle systems. The one thing that sets our Owens Corning work here apart is that we plan every job around what Ventura’s marine layer and Santa Ana winds actually do to these shingles, not what the brochures claim. Call (559) 249-4917 for a free estimate on your Owens Corning roof.
Dylan Pace and our Crestview Roofing Co Ventura crews have worked on Owens Corning systems throughout this city for years. We’re an independent roofing company, not factory-authorized by Owens Corning, so you get straight answers about which of their products hold up on Ventura’s coastal and hillside homes and which ones need a little reinforcement. Our Owens Corning sales & service page covers the full scope of what we do, but this page is specific to what we see in Ventura.
Why Ventura Residents Choose Us for Owens Corning Service
Owens Corning shingles show up on a large share of the 1920s-to-1970s single-family homes across Ventura, especially the composition shingle roofs on older stucco-clad developments. The issues we fix here are rarely the shingle itself failing early. More often it’s the metal around the shingles, the underlayment beneath them, or an install detail that was never right for this climate. Dylan trained at Los Angeles Trade-Technical College and has been working roofs across Ventura County long enough to tell the difference between a roof that looks good on install day and one that still performs a decade later.
When you book with us, you get a written price before any work starts, a live trackable arrival time, and before-and-after photos so you can see exactly what we did. That’s The Relay Standard, and it applies to every Owens Corning repair or replacement we do in Ventura. No four-hour windows and no price that shifts once the crew shows up.

Common Owens Corning Roofing Problems We Solve in Ventura
- Premature granule loss on Duration and Oakridge shingles. West- and south-facing slopes in Ventura take the full brunt of coastal UV and salt-laden air, and Santa Ana wind events accelerate the shedding. We see roofs lose granules years before the shingle itself cracks, which shortens the roof’s life and leaves a mess in the gutters.
- Wind blow-off at eaves and rakes on older Supreme three-tab installs. Many of Ventura’s exposed hillside homes have older Supreme roofs where nails missed the 1-1/4-inch nailing strip. When a Santa Ana hits, the shingle tabs lift and peel. This is a repair we make regularly on the hillside streets above Ventura Avenue.
- Corroded step flashing and pipe collars. The marine layer sits against shingle edges for hours each morning from spring through fall. That persistent moisture eats through galvanized flashing at valleys, sidewalls, and vent boots, leading to the slow leaks homeowners first notice during winter’s first heavy rain.
- Brittle or cracked hip and ridge caps. Thermal cycling, hot dry summers followed by cool damp nights, takes a toll on 15-to-20-year-old Oakridge caps in the Ventura Keys and beachside districts. The caps crack before the field shingles do, and that’s where water gets in.
- Inadequate underlayment on older homes. Many 1940s and 1950s Ventura homes were built before modern wind-uplift and moisture-barrier requirements existed. When we pull back an old Owens Corning roof, we often find thin, cracking felt that needs a full upgrade before the new shingles go down.
Owens Corning Service in Ventura: What Local Conditions Mean for Your Roof
Here’s the Ventura-specific fact that shapes more of our Owens Corning work than anything else: in the Ventura Keys, salt spray from the harbor and estuary breezes corrodes standard galvanized roof flashing to failure within 10 to 15 years. That’s a significantly faster timeline than in the drier, inland parts of Ventura like Saticoy or Montalvo, where the same flashing might last 20-plus years. If you own a home in the Keys, your Owens Corning shingles may look fine while the metal keeping water out is quietly rusting through behind them.
Our answer is heavier-gauge stainless or copper flashing at every transition, valley, and pipe collar. It costs more upfront, but it matches the actual service life of a new Owens Corning roof in a salt-air environment. Our tech responded to a leak in a 1970s Spanish-style home in the Ventura Keys where the Oakridge shingles were still in decent shape, but the galvanized step flashing at a sidewall had rusted through after a decade of salt-laden air. We replaced it with 26-gauge stainless steel, pulled back and re-sealed the shingles, and added a corrosion-resistant underlayment at the transition. The owner hasn’t seen a drop since, and we flagged two nearby pipe collars for replacement before they failed. That’s the kind of early catch you get when the person on the roof knows exactly what Ventura’s marine layer does to metal.
Owens Corning Models & Products We Service in Ventura
We spec, repair, and replace the full family of Owens Corning residential shingle lines: Duration Series, Oakridge Series, Supreme Series, and TruDefinition Duration Designer. For any spot repair or partial reroof, we use genuine Owens Corning shingles and accessory products so the color, profile, and wind rating match the existing roof. If a color has been discontinued or the owner wants to cut cost, we walk through honest aftermarket alternatives but always flag the visual mismatch and reduced warranty on the patched area. We stock the most common Owens Corning accessory components locally so Ventura repairs don’t wait on a distributor’s shipping schedule.

AfterOwens Corning Service Pricing in Ventura

A partial reroof of one slope usually starts around $1,800, while a full Owens Corning tear-off and replacement on a typical 1,600-square-foot Ventura home generally lands between $12,000 and $22,000 depending on shingle line, underlayment upgrades, and flashing scope.

FAQs – Owens Corning Roofing in Ventura
The side of your roof facing west or south takes direct afternoon sun plus the brunt of salt-laden marine air and Santa Ana wind gusts, which strips granules from Owens Corning Duration and Oakridge shingles faster than the shaded slope. We can assess how much granule loss you have and whether it’s cosmetic or structural. Call (559) 249-4917 for a free roof assessment.
Sometimes we can source remaining stock of a discontinued Owens Corning color through our distributors, but if that fails, we’ll show you the closest current colors side by side and tell you honestly whether the difference will be noticeable from the street. We never promise a match we can’t deliver.
Ventura’s coastal and hillside zones require stronger nail patterns and often a wider underlayment bond than inland installs, so we follow current California Building Code wind-uplift requirements and Owens Corning’s high-wind install specs. On older homes we typically add a modern synthetic underlayment because the original felt was never designed for the wind-driven rain we get here.
No. Owens Corning’s shingle warranty covers manufacturing defects in the shingle itself, not corrosion of the metal flashing or accessories, which are typically covered by the accessory manufacturer or installer for a much shorter period. This is exactly why we recommend stainless or copper flashing on Ventura Keys and beachside homes. Call (559) 249-4917 to see if your flashing is at risk.
In Ventura’s coastal climate, an Owens Corning Duration roof with correct installation and upgraded flashing typically lasts 25 to 30 years, while a Supreme three-tab usually reaches 15 to 20 years. Salt air, Santa Ana winds, and original-install shortcuts can pull those numbers down by 5 to 10 years. The best way to know where your roof stands is an honest inspection, so call (559) 249-4917 to schedule one.
