Owens Corning Roofing in Northridge, CA | Hollywood Roofing Co
We’re an independent Owens Corning roofing contractor serving all of Northridge, and we fix and replace these shingle systems with a level of local detail most crews don’t have. We also handle Owens Corning in North Hills and surrounding Valley areas. What sets our work apart here is simple: we know what a 1994 earthquake repair looks like on an Owens Corning roof, because we’ve opened up hundreds of them across the 91327, 91328, 91329, and 91330 ZIP codes. Owens Corning’s asphalt shingles are solid products, but in Northridge they live on rooftops with a seismic history that directly shapes how they fail and how they should be repaired. Call (833) 589-7971 for a straight answer on your roof.
Why Northridge Residents Choose Us for Owens Corning Service
Roland Vega has been on roofs in this valley for the better part of three decades, and he’s seen what Northridge-specific conditions do to Owens Corning shingles that were installed well and shingles that weren’t. That matters when you’re deciding between a patch and a replacement. We’re a full-lifecycle roofing company, which means we inspect, repair, and replace, and our Owens Corning sales & service work is built on that same principle: figure out what’s actually wrong before touching anything.
Because we install seven major brands, including Owens Corning, we don’t have a reason to push you toward a shingle that doesn’t fit your home, whether you need Owens Corning in Encino or anywhere else we serve. We’ll tell you when an Owens Corning repair makes sense and when it doesn’t. Our recommendations are matched to your home and your budget, not to a supplier incentive.

Common Owens Corning Roofing Problems We Solve in Northridge
- Post-1994 earthquake patchwork failures. Many Northridge Owens Corning roofs were re-nailed or partially re-roofed under emergency permits after the quake. We regularly find a mix of original and newer shingles that don’t match in age or nailing pattern, which leads to premature failure and wind uplift during Santa Ana events.
- Granule loss and brittleness on west-facing slopes. Northridge’s inland heat regularly pushes past 100°F. Owens Corning’s standard 3-tab shingles, like the Supreme series, can lose granule adhesion and become brittle on slopes that take direct afternoon sun. A brittle shingle doesn’t flex with the decking; it cracks.
- Seal-down failures on Duration shingles. Duration architectural shingles hold up better overall, but when they’re installed over uneven or patched decking from earthquake-era re-roofs, the seal strip can miss. The result is shingle flutter in high winds, and eventually a leak.
- Flashing and vent boot failures from reused fasteners. We trace a lot of Owens Corning roof leaks to flashings and vent boots that were installed or re-installed using original 1970s fasteners. Those fasteners don’t meet current seismic tie-down standards and they corrode. Where the fastener fails, water follows.
- Mismatched replacement shingles from past repairs. If a previous contractor repaired your Owens Corning roof with a different brand or a different color lot, you’ll see it every time you pull into the driveway. More importantly, mismatched shingles create weak points where water and wind get underneath.
Owens Corning Service in Northridge: What Local Conditions Mean for Your Roof
Northridge sits directly on the San Fernando Valley’s northern seismic edge, close enough to the 1994 epicenter that a huge share of the housing stock here has an earthquake repair somewhere in its history. For Owens Corning owners, that history changes what a roofing contractor should be looking for. On a 1960s ranch home near Reseda Boulevard and Plummer Street, we found an Owens Corning Oakridge roof that had been patched after the quake with mismatched shingles and inadequate nailing. During a Santa Ana windstorm, several shingles lifted and exposed the underlayment, causing a leak into the living room. We replaced the damaged sections with matching Oakridge shingles, re-nailed the entire perimeter to current seismic standards, and installed new flashing around the chimney, solving both the leak and the wind vulnerability. A roofer who only looks at shingle condition would have missed the nailing pattern issue entirely. Around here, that’s the difference between a repair that holds and one that fails the next time the wind blows hard.
Owens Corning Models & Products We Service in Northridge
We work on the full Owens Corning asphalt shingle line: Oakridge, Duration, Supreme, and Berkshire. When we replace shingles, we use genuine Owens Corning products so the warranty stays intact and the color matches. For underlayment and fasteners, we source high-quality aftermarket materials that meet or exceed current code. Our crews keep common Owens Corning shingle colors staged for Northridge jobs, which means we’re not waiting on a shipment from out of state before we can close up your roof. That’s a real advantage when a leak has already started.

AfterOwens Corning Service Pricing in Northridge
What you’ll pay depends on what we find. A small leak repair at a vent boot or sidewall flashing is usually a few hundred dollars. Replacing a damaged section of Owens Corning shingles runs more, especially if we’re also correcting the nailing pattern underneath. A full roof replacement in Northridge for a typical 1950s-1970s ranch runs higher, and tile underlayment replacement under concrete tile is a different scope entirely. The free estimate includes a written, line-item breakdown and photos of what we found, so you know exactly what you’re paying for. Call (833) 589-7971 to schedule yours.

FAQs – Owens Corning Roofing in Northridge
Yes, in most cases we can match the shingle series and color. Oakridge and Duration shingles from recent years are widely available, and we keep common Northridge colors staged. Older Supreme 3-tabs that have been baking in valley sun for 15 years will have faded, so the match won’t be seamless, but it’ll be close. Call (833) 589-7971 and we’ll take a look.
It can. Insurance adjusters scrutinize earthquake-era repairs closely, and if the patchwork doesn’t meet current standards, they may reduce or deny a wind-damage claim. We document existing earthquake repairs in writing and with photos before we start any new work, so you have a clear record for your insurer. Call (833) 589-7971 if you want us to assess it.
Duration and Oakridge architectural shingles handle Northridge heat well when they’re installed over sound, even decking. The problem is when the decking underneath is uneven from old repairs, because the seal strip can’t grab properly. That’s a workmanship and substrate issue more than a shingle issue, and it’s fixable. Call (833) 589-7971 for an honest assessment of what’s happening up there.
Yes. When a concrete tile roof in Northridge has Owens Corning underlayment, we replace it with a compatible high-quality aftermarket underlayment that meets code. The tile gets lifted, the old underlayment comes off, and new goes down before the tile is re-set. Call (833) 589-7971 and we’ll tell you if your underlayment is at the end of its service life.
Seal-down failure and wind uplift caused by earthquake-era nailing patterns. After 1994, a lot of these roofs were re-nailed quickly, and the nails went in too close to the shingle edge or with inconsistent spacing. That’s what causes shingle flutter during Santa Ana winds. We correct the nailing, replace damaged shingles, and install new flashing as needed. Call (833) 589-7971 for a roof inspection that looks at the decking, not just the shingles.
