Owens Corning Roofing in Northridge, CA | Orange County Roofing Co
We provide independent Owens Corning roofing service across Northridge, from shingle repairs to full tear-off replacements. What makes our Owens Corning work here different is simple: we know what the 1994 earthquake did to roofing in this city, and we know what 100-degree Valley summers do to shingles after that kind of repair history. Call (866) 942-4187 for a free estimate on any Owens Corning roof in Northridge.
Why Northridge Residents Choose Us for Owens Corning Service
We’re an independent contractor, and that’s the point we want to be upfront about. We are not authorized, sponsored, or endorsed by Owens Corning. What we do offer is years of hands-on experience tearing off and rebuilding Owens Corning systems across the San Fernando Valley, including hundreds of roofs in Northridge. Kurt Hensley, our owner, started working roofs in Orange County before he ever wore a company hat, and he’s spent two decades looking at exactly the kind of shingle failures Valley homeowners deal with. If we had a dollar for every improperly flashed chimney in this zip code, well, we’d probably still be roofing. The work is what matters, and it’s what keeps people calling us back.
Our Owens Corning sales & service approach is straightforward: genuine Owens Corning materials matched to your existing profile and color wherever possible. We’re a full-service roofing company, so a single damaged shingle and a complete replacement both get the same careful diagnosis. We also carry six other major brands at the same time, which means when we tell you a repair makes sense, it’s because the roof says so, not because we’re stuck selling one product.

Common Owens Corning Roofing Problems We Solve in Northridge
- Heat-seal failure and tab uplift. Northridge summers routinely exceed 100°F, and south-facing and west-facing slopes take the worst of it. The adhesive strip on Owens Corning shingles bakes brittle in that heat, and the first hot, dry wind of the season lifts tabs before the field even shows granule loss. We see this constantly on homes throughout 91325 and 91330.
- Granule loss and sun-cracking from relentless UV. Owens Corning shingle fields facing south or west in the Valley cook faster than the manufacturer’s estimates suggest. The fiberglass mat gets exposed, and water intrusion starts quietly. You won’t see it until the winter rains arrive, and by then the decking may already be damaged.
- Mismatched shingle lots from post-1994 reconstruction. After the earthquake, crews in Northridge often nailed a different Owens Corning shingle color or profile over a patched section, just to get a roof covered. The transitions between those lots are where we find curling and leaks first. It’s a problem that’s more common in Northridge than nearly anywhere else in the Valley.
- Dry, cracked underlayment under retained concrete tile. Many Northridge homes kept their post-quake tile roofs, and that tile often outlives the underlayment. Owens Corning WeatherLock or older felt underlayment dries out and cracks, and leaks show up at the tile edge or valley after the first real rain. The tile looks fine. The underlayment is not.
- Leaks at quake-era valley flashing. When we tear into a Northridge roof, we regularly find valley flashing that was nailed flat during the rush to rebuild after 1994. Water doesn’t care that the shingles are new if the valley isn’t directing it properly.
Owens Corning Service in Northridge: What Local Conditions Mean for Your Equipment
Northridge’s 1994 earthquake triggered a rush of roof repairs that were often done with mismatched tile and patched underlayment. When we tear into an Owens Corning shingle or tile assembly in this city, we routinely find quake-era repairs that were never properly flashed. That’s the hidden variable that separates Northridge from neighboring San Fernando Valley cities without that specific reconstruction history. On a 1960s stucco ranch near Reseda Boulevard in 91325, the homeowner called about a ceiling stain after the first December rain and assumed it was the thirty-year-old Owens Corning three-tab field. Our tech found the shingle job was post-quake coverage over a patched section with mismatched tile and a valley flashing that had been nailed flat. We did a full tear-off, replaced rotted decking, and set a new Owens Corning Duration field with a rebuilt valley. The leak never came back the following winter. That’s the kind of roof Northridge has, and it’s the kind we’re built to fix.
Owens Corning Models & Products We Service in Northridge
We work on the full Owens Corning line that’s common across Northridge. That includes Duration architectural shingles, which we install most often on full replacements, Oakridge architectural shingles, and Supreme 3-tab shingles that are still holding on from earlier re-roofs. We also handle WeatherLock self-adhered underlayment beneath retained tile. When a discontinued lot can’t be matched, we tell you honestly rather than patch with a color that reads wrong from the street. A roof shouldn’t be a mystery, and we’d rather explain your options than sell you something you’ll regret looking at every time you pull into the driveway.

FAQs – Owens Corning Roofing in Northridge
Yes. We inspect for the specific failure patterns common to quake-era repairs in Northridge: mismatched lot transitions, improperly flashed valleys, and heat-sealed tabs that have gone brittle over twenty-plus years of Valley summers. We’ll tell you what’s actually failing and what can wait, without pushing a replacement you don’t need yet. Call (866) 942-4187 to schedule an inspection.
They will if the installation and ventilation are done correctly. But south-facing and west-facing slopes in Northridge take extreme UV and heat year after year, and we commonly see Owens Corning shingle fields on those exposures age faster than manufacturer estimates predict. The adhesive strip is the first thing to fail. If you’re noticing lifted tabs or granule in your gutters, get it looked at before winter rains. Estimates are free at (866) 942-4187.
Yes, we do tile underlayment replacement as a standalone service in Northridge. This is a common job here because concrete tile often outlives the underlayment beneath it. We remove the tile carefully, replace the old dried-out underlayment with new material, and reset the tile. If the tile itself is still sound, this is far cheaper than a full replacement. Call (866) 942-4187 for a quote specific to your roof.
The most common reason in Northridge is hidden quake-era repair work. Your neighbor may have had a full tear-off after 1994, while your roof may have been patched over existing layers with mismatched material and improperly sealed transitions. The shingle field can look fine from the street while water is getting in at the valley or flashing. We inspect from the deck up to find what’s actually leaking. Call (866) 942-4187 to have us take a look.
We install Owens Corning Duration shingles on full replacements across Northridge, along with Oakridge and other Owens Corning lines. Duration is our most common recommendation for Valley homes because it handles heat and UV better than older 3-tab designs, and it’s what we’ve seen perform well on the slopes here. Call (866) 942-4187 for a free estimate on a new Duration field.
