AfterOwens Corning Roofing in Santa Ana, CA | Brennan Roofing
We’re an independent Roofing Company - Santa Ana that installs and repairs Owens Corning roofing systems across the city, from French Park to Floral Park. Most of the Owens Corning work we do in Santa Ana isn’t pitched shingle replacement, it’s flat and low-slope membrane repair, tile underlayment replacement, and parapet flashing fixes on pre-1960 homes. Call (361) 320-9467 for a free estimate, and you’ll get the price in writing before any work starts.
Why Santa Ana Residents Choose Us for Owens Corning Service
Owens Corning makes solid roofing materials, but how they hold up depends on where they’re installed. Santa Ana’s dense inventory of 1920s through 1950s Spanish Colonial Revival and Craftsman homes means we’re rarely doing the straightforward shingle work you’d see in Owens Corning repair in Irvine or Mission Viejo. We’re usually up against low parapet walls, original skip sheathing, and decades of patched clay tile.
Travis Oakley, our owner, grew up in the San Fernando Valley and trained in building construction technology at Los Angeles Trade-Technical College before spending nearly two decades on production and repair crews across Los Angeles County. He still pulls his own inspections and will tell you flat-out if a repair is the right call instead of a full replacement. That honesty is the whole reason Brennan Roofing exists. A roof that’s squared away doesn’t need a sales pitch.
Every job we take on in Santa Ana begins with a written price before any work starts. Our technicians are background-checked and arrive in uniform. And we back every Owens Corning repair or installation with the 365-Day Done Right Promise: if it’s not done right, we come back and make it right, in writing, at no charge, for one full year.
Common Owens Corning Roofing Problems We Solve in Santa Ana
Here’s what we see most often with Owens Corning systems in this city:
- Duration® Series shingles losing their seal strip. On south- and west-facing slopes in Santa Ana, the intense year-round UV breaks down the SureNail® adhesive strip faster than you’d expect. We routinely find the fabric strip peeling back and shingle tabs lifting after 15 to 20 years. When the Santa Ana winds hit in October and November, those loose tabs tear right off.
- Oakridge® shingle granule loss and wind lift on low-slope sections. Santa Ana has thousands of small rental units and converted garages with flat or low-slope roofs. Oakridge® shingles weren’t designed for those slopes, and we see granule loss and cracking accelerated by UV exposure. During a 40 to 60 mph Santa Ana wind event, the tabs lift and tear.
- WeatherGuard® underlayment failing at ponding seams. This is a big one in Santa Ana. Flat roofs with inadequate drainage pond water for days after a winter storm, and WeatherGuard® underlayment at the seams eventually lets water through. During El Niño years, when inches of rain fall in a matter of days, every weak seam shows itself at once.
- Berkshire® Collection shingles cracking along the ridge. These are heavier shingles with larger tabs, and when attic ventilation is poor, the heat buildup in Santa Ana’s semi-arid climate causes stress cracking along the ridge line. The larger tabs also catch more wind on exposed edges.
- Flashing failures at parapet walls. This is the one most people can’t see from the ground. Santa Ana’s low parapet walls hide a lot of roof problems, and when the flashing at those walls fails, water runs down inside the wall cavity and shows up as ceiling stains inside the house. By the time you see it, the underlayment underneath is already compromised.
Owens Corning Service in Santa Ana: What Local Conditions Mean for Your Equipment
Here’s a checkable fact that shapes Owens Corning work in Santa Ana more than anywhere else in Orange County: the historic French Park and Floral Park neighborhoods have strict preservation review for any roof visible from the street. You can’t just pull off original clay tile and replace it with a modern shingle, you have to match the original profile or get city approval first. For Owens Corning owners, that means a simple tile underlayment replacement can become a project that requires custom fabrication and city sign-off. Our crews have done that work in Floral Park on a 1928 Spanish Colonial Revival. The low parapet and brittle original tile had let wind-driven rain seep under the underlayment during a winter storm. We replaced the failed WeatherGuard® underlayment, re-flashed the parapet, and matched the existing tiles without changing the historic street view. The leak was fixed without a full tear-off. That kind of work is routine in Santa Ana and almost unheard of in neighboring suburbs.
Owens Corning Models & Products We Service in Santa Ana
We work on the full Owens Corning residential line: Duration® Series shingles, Oakridge® shingles, and the Berkshire® Collection, plus WeatherGuard® underlayment systems. For shingle and underlayment replacement, we use Owens Corning OEM materials to ensure color and performance matching. For accessories like vents, flashing, and fasteners, we use high-quality aftermarket brands that meet or exceed OEM specifications at a better price. We stock common Owens Corning profile colors and underlayment rolls locally, which keeps turnaround faster for Santa Ana customers. Every job starts with an assessment: if a targeted repair can extend the life of your roof by several years, that’s what we’ll recommend.
Owens Corning Service Pricing in Santa Ana
What you’ll pay depends on the work, but here are honest ranges for Santa Ana:
- Flat roof patch (membrane or modified bitumen): $350 to $900, depending on the size of the failed section and whether we need to replace wet underlayment.
- Tile underlayment replacement under existing tile: $4 to $8 per square foot. Historic district approval in French Park or Floral Park can add time but not much cost.
- Flashing repair at a parapet wall: $250 to $600 per wall, depending on length and whether existing flashing can be reused.
- Full Owens Corning Duration® shingle replacement on a standard pitched roof: $6 to $9 per square foot installed, tear-off included.
The free estimate includes a written line-item price before any work starts. That number does not move at the door. Call (361) 320-9467 to schedule yours.

FAQs – Owens Corning Roofing in Santa Ana
Yes, in most cases we can match the original clay tile profile or source a close reproduction. For homes in French Park and Floral Park, we handle the preservation review paperwork as part of the estimate. Call (361) 320-9467 and we’ll walk you through what city approval involves for your specific street.
The hot, dry 40 to 60 mph gusts we get every fall strip the adhesive from the SureNail® strip over time, especially on south- and west-facing slopes. Once the seal fails, the tabs lift and tear during the next wind event. If you’re seeing loose tabs after a windy week, call (361) 320-9467 for a Roof Repair - Santa Ana estimate before the next storm cycle hits.
Ponding water on a flat roof means the drainage isn’t working, and WeatherGuard® seams will eventually fail under that standing water. We’d first clear and assess the drains, then check the seams for water intrusion. The repair might be as simple as seam re-sealing, or you may need sections of underlayment replaced. Call (361) 320-9467 and we’ll give you a written price either way.
No. Shingles are not the right product for low-slope or flat roofs, and we won’t install them that way. For the flat and low-slope roofs common on Santa Ana’s older homes and converted garages, we use membrane systems or modified bitumen. If you currently have shingles on a low-slope roof, that’s likely the source of your leaks, and we’ll tell you honestly.
In Santa Ana’s intense year-round UV, you’re looking at 15 to 22 years for Duration® shingles and slightly less for Oakridge®, depending on slope orientation and ventilation. That’s shorter than the manufacturer’s ideal-condition lifespan, but it reflects what our crews actually see on roofs across this city. If your roof is approaching that age, we can inspect and tell you whether a repair will buy you years or whether replacement is the smarter spend. Call (361) 320-9467 to set that up.
