AfterOwens Corning Construction in Santa Ana, CA | Rowan Construction Group
We provide independent Owens Corning roofing and insulation service across Santa Ana, from Logan to Lacy to Willard. The one thing that makes our Owens Corning work here different is this: virtually every pre-1960 home we touch has at least one unpermitted addition, and those additions almost always have Owens Corning shingles that were never installed to manufacturer spec. That changes how a roof must be inspected, permitted, and repaired. Call (470) 298-9650 for a free estimate.
Why Santa Ana Residents Choose Us for Owens Corning Service
We’ve worked on hundreds of Owens Corning roofs in Santa Ana’s dense urban core, and that field experience means we know exactly how Duration® and Oakridge® shingles perform under the city’s fall wind events and relentless UV exposure. We also offer Owens Corning repair in Irvine for homeowners just outside the city limits. Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College and has spent two decades working on residential remodels across Los Angeles and Orange County. His background in framing and estimating shows up in how we document every roof: the photo record, the written scope, the signed change order. You get a flat written price before any work starts, and a live person answers the phone at (470) 298-9650.
We’re an independent Owens Corning service provider. We are not manufacturer-affiliated or authorized, and we don’t pretend to be. That independence means we can look at an Owens Corning roof and tell you honestly whether it needs a section repair or a full replacement, and we can specify a better third-party underlayment where Santa Ana conditions demand it. It also means you deal directly with the contractor who does the work, not a brand representative. See more about our Owens Corning sales & service approach.
Common Owens Corning Construction Problems We Solve in Santa Ana
- Blown-off shingle tabs on windward edges. Santa Ana’s namesake winds regularly exceed 50-60 mph in fall and winter. The windward roof edges of 1920s-1950s bungalows take the brunt. We frequently find brittle, torn, or missing Owens Corning shingle tabs that were either nailed too high or installed over inadequate underlayment.
- Granule loss and cracking on south-facing slopes. Santa Ana’s Mediterranean climate means minimal cloud cover. South-facing Owens Corning shingles get decades of intense UV radiation, which breaks down the asphalt binder and causes severe granule loss. By the time you see granules in your gutters, the shingles are usually well into their decline.
- Leaks around penetrations on unpermitted rear additions. The rear addition that was added in the 1980s without plans almost always lacks proper flashing and Owens Corning underlayment at roof penetrations, valleys, and wall junctions. Water finds those gaps fast, especially during wind-driven rain.
- Moisture damage at original wall and newer addition junctions. We see thermal bypass and trapped moisture where the original lathe-and-plaster walls meet newer Owens Corning-insulated additions, especially in homes where knob-and-tube electrical was replaced without proper air sealing. The insulation works, but the air leaks undermine it.
- Shingles installed directly over old wood shake. This is a Santa Ana-specific failure pattern. Decades of affordability pressure led to overlayment without tear-off. Owens Corning shingles nailed directly over wood shake have no flat substrate, no proper underlayment, and premature failure is guaranteed.
BeforeAfterOwens Corning Service in Santa Ana: What Local Conditions Mean for Your Equipment
The City of Santa Ana Building Division has a rule that surprises most homeowners. If you live in a pre-1960 home with an unpermitted addition, any new permit application, including a roof replacement, can trigger a mandatory “as-built” plan submittal. That means documenting the entire rear addition that was added in the 1980s before the city will allow work on the main roof. This requirement has doubled or tripled the timeline on projects homeowners assumed were straightforward. But it matters for your Owens Corning roof specifically, because those unpermitted additions almost always have shingles that were never installed to manufacturer spec. Wind-uplift zones, missing underlayment, improper nailing patterns. A generic roofing page will not mention this. A competent local contractor has to. Measure twice, say it once, show your work.
Owens Corning Models & Products We Service in Santa Ana
Our crews work daily with Owens Corning Duration® Series, Oakridge®, TruDefinition® Duration FLEX®, and Supreme® shingles. When a Santa Ana roof is within its service life, we repair with genuine Owens Corning color-matched shingles and the manufacturer’s accessory products. When the existing deck or underlayment is compromised, we use a superior third-party ice-and-water shield and flashing that handles Santa Ana’s wind-driven rain better than standard materials. That’s the honest approach: OEM where it protects the warranty, better-than-OEM where conditions demand it.

FAQs - Owens Corning Construction in Santa Ana
Will I need an as-built plan for my Owens Corning roof replacement in Santa Ana if I have an old unpermitted addition? Yes, in most cases. Santa Ana’s Building Division routinely requires an as-built plan for structures added without permits before it will approve a new roof permit. We document the existing framing, submit the plan, and fold that step into your written scope before work begins. Call (470) 298-9650 for an exact assessment of your property.
Why do my Owens Corning shingles keep blowing off only on the back side of my Santa Ana bungalow? Because that’s the windward side. Santa Ana winds come from the northeast, and the rear roof edge of a craftsman bungalow catches those 50-60 mph gusts directly. Missing or torn shingles there usually indicate the original installation nailed shingles too high on the tab or used inadequate underlayment. We fix both the shingles and the underlying installation problem.
Can I install Owens Corning shingles directly over my old wood shake roof in Santa Ana? No. The city’s current codes and Owens Corning’s installation specs both require a flat, solid deck. Wood shake provides neither. We’ve seen more than one Santa Ana home where shingles were overlaid directly on shake and failed within a few seasons. The correct fix is tear-off, re-deck, and proper underlayment. Call (470) 298-9650 to discuss your roof’s condition.
How do I know if my Owens Corning roof needs replacement or just repair after a Santa Ana wind storm? If the storm damage is limited to a few torn shingle tabs along one roof edge, a section repair with color-matched Owens Corning shingles is usually sufficient. If you see widespread granule loss, blistering, or water stains on ceilings in multiple rooms, the roof deck and system are likely beyond repair. We document everything with photos and give you a straight answer. Estimates are free at (470) 298-9650.
Does your company provide Owens Corning shingles for the steep roof pitches on Santa Ana craftsman bungalows? Yes. The 8:12 and 10:12 pitches common on 1920s-1950s craftsman bungalows in Santa Ana require shingles rated for steep-slope installation and crews experienced with fall protection and staging on tight urban lots. We stock Owens Corning Duration and FLEX lines for exactly these jobs.
