Owens Corning Roofing in Northridge, CA | Van Nuys Roofing Co
We provide independent Owens Corning roofing installation and repair across Northridge, from ZIP 91324 up through 91330. The one thing that makes our Owens Corning work different here is simple: Northridge roofs carry thirty years of earthquake-repair history under their shingles, and we know what that means before we tear anything off. If you’re weighing a repair against a full replacement on an Owens Corning roof, call (866) 321-6172 and we’ll walk it with you, shingle by shingle.
Why Northridge Residents Choose Us for Owens Corning Service
We handle Owens Corning Duration and Oakridge roofs every week across the San Fernando Valley, so we know how their sealant strips and mat construction behave under Northridge sun. We are not authorized, sponsored, or endorsed by Owens Corning, and we say so plainly. What that means for you is straightforward advice: we’ll tell you when a repair holds and when it’s money into a roof that’s already done. Rick Dominguez grew up a few blocks from the old Van Nuys Municipal Airport, learned the trade through the construction technology program at Los Angeles Valley College, and spent two decades on Valley rooftops before starting Van Nuys Roofing Co., now offering Owens Corning service in Van Nuys. His rule on every estimate is simple: if it doesn’t need replacing, we’re not going to tell you it does.
Owens Corning shingle systems are one of seven major brands we work with, alongside GAF, CertainTeed, IKO, Atlas, Tamko, and Boral. That breadth matters in Northridge because we’re not steering you toward one manufacturer’s product line. Your roof, your material choice. We inspect first, recommend second. For Owens Corning homeowners, that means an honest read on whether their Duration or Oakridge roof has another five years in it or is one winter storm from real trouble.
We’re an independent Owens Corning sales & service contractor serving the Northridge area, and we use genuine Owens Corning shingles plus matching starter strips, hip-and-ridge cap, and underlayment where the system needs to stay consistent. Where flashing or vent boots fail, we’ll often use quality aftermarket components that outperform OEM equivalents, and we’ll tell you exactly why.

Common Owens Corning Roofing Problems We Solve in Northridge
- Sun-baked sealant strips on older Oakridge and Supreme three-tab roofs. Northridge’s hot, dry summers sit on an Owens Corning roof for decades. The self-sealing adhesive gets brittle after 12 to 15 years of full Valley sun. We see wind-driven winter gusts lift tabs along the ridge and field because they never re-sealed, and that opens the roof to rain. A leak on one slope often turns into a field of unsealed tabs.
- Granule loss and hairline mat cracking over quake-era patched decking. On 2000s-era re-roofs, Duration shingles installed over reused tile-adjacent patched decking show early granule loss where the deck below had patch seams from the 1994 earthquake that were never flattened. The shingle flexes over the uneven seam, the mat cracks, and the roof wears unevenly. We see this in Northridge more than anywhere else in the Valley.
- Flashing and vent boot failures paired with Owens Corning installations. Valley heat dries out flashings and vent boots faster than the shingles around them. That turns a shingle warranty question into a flashing or boot leak the shingles themselves didn’t cause. We check both before we quote anything.
- Brittle underlayment beneath sound Owens Corning shingles. Many Northridge homes re-roofed after 1994 kept original concrete tile sections over underlayment that’s now thirty years old. When an Owens Corning shingle section sits beside a tile section or converted patio, the underlayment under the shingle side is often the first thing to fail, even when the shingles above look fine.
- Wind damage on shallow-pitch ranch roofs. Northridge’s 1950s and 1960s ranch-style homes often have low-slope sections where Owens Corning architectural shingles meet ridge vents. Winter gusts coming down from the Santa Susana Pass find every unsealed tab, and we get called after the first big rain of the season.
Owens Corning Service in Northridge: What Local Conditions Mean for Your Roof
Northridge is the epicenter of the 1994 earthquake, and the roofing trade here is still shaped by that morning. Thousands of tile roofs were re-laid or repaired in the years after the quake, and many of those repairs are now thirty years old. What we find on Owens Corning shingle roofs in Northridge, particularly in ZIP 91325 and 91324, is a second generation of seismic-related failures: original concrete tiles still sound but the underlayment beneath them brittle and cracked, patched decking with seams that were never flattened, and shingle sections over additions or converted patios tied into old quake-repair work. When an Owens Corning shingle roof sits on a Northridge home with a tile-section addition, our tear-off frequently exposes failing quake-era underlayment that no other Valley city sees at this rate.
We tore off an Oakridge roof on a ranch home off Reseda Boulevard in ZIP 91325 that had been installed over a quake-era tile repair with a reused concrete tile section on the rear slope. The original tiles were still solid, but the underlayment beneath them had gone brittle and cracked. We replaced the underlayment, flattened the patched decking, and re-roofed in Duration shingles with new vent boots and valley flashing. That’s Northridge roofing work in a single job: the visible layer looked fine, and the thirty-year-old layer underneath was done.
The Valley’s hot, dry summers bake asphalt shingles and sealants, and the occasional winter rains expose every weakness in aged underlayment or quake-repaired sections. For Owens Corning owners specifically, that means the adhesive strip on your architectural shingles is losing its grip every summer, and the decking underneath may have been compromised long before the shingles went on. We inspect with that history in mind, because in Northridge the failure is often two layers down.
Owens Corning Models & Products We Service in Northridge
We install and repair the full Owens Corning residential lineup in Northridge: Duration Premium Architectural Shingles, Oakridge Architectural Shingles, Supreme Asphalt Shingles, and Duration Storm shingles with enhanced impact resistance. For repairs, we use genuine Owens Corning shingles and matching accessory components where the system needs to stay consistent, so a patch on a Duration roof doesn’t stand out like a wrong-colored square. We stock common Duration and Oakridge colors locally for faster Northridge turnaround, and we’ll order specialty colors when the roof calls for them.
Our crews handle shingle replacement, full roof replacement, and tile underlayment replacement as core services. When an Owens Corning roof sits adjacent to a concrete tile section, we coordinate both sides of the transition so the new underlayment ties in clean and the shingle-to-tile junction doesn’t become the next leak point.

AfterOwens Corning Service Pricing in Northridge
Owens Corning roofing work in Northridge is priced by the scope of the problem, not by a flat rate pulled from a menu. A small shingle replacement or flashing repair runs lower than a full tear-off, and a full Duration or Oakridge re-roof is a different conversation entirely. What drives the quote is what we find: underlayment condition, decking flatness, the number of transitions between shingle and tile sections, and whether the quake-era patch work underneath is holding. Our free estimate includes an inspection of the shingles, the underlayment where accessible, the flashings, and the vent boots, so you know what you’re actually paying for before we start.
We’ll give you a written, line-item quote. No change orders because we found something we should have caught the first time. Call (866) 321-6172 and we’ll come out, walk the roof, and tell you what it needs and what it doesn’t.

FAQs – Owens Corning Roofing in Northridge
Yes, in most cases we can repair just the Owens Corning shingle section without touching the tile side, as long as the transition between the two is intact. But we’ll inspect the underlayment under both sections before we quote, because in Northridge the underlayment under the tile side is often worse than the shingle side looks. Call (866) 321-6172 and we’ll tell you which side actually needs work.
Granada Hills saw less intense shaking in 1994, so its roofs don’t carry the same quake-repaired decking that Northridge homes do. For Owens Corning in Valley Glen, the same pattern holds. If your Owens Corning shingles sit over patched decking with unflattened seams, the shingle mats flex over those seams and shed granules faster. Northridge’s sun exposure accelerates it further. It’s not your shingles being defective; it’s the decking underneath.
No. We replace the shingle sections independently and tie the new underlayment and flashing into the tile transition without lifting intact concrete tiles unless the underlayment beneath them has already failed. If the tile-side underlayment is brittle, which it often is in Northridge after thirty years, we’ll recommend addressing it while we’re up there. Repair or replace, we’ll tell you which one actually makes sense.
Northridge’s full Valley sun bakes every asphalt-based sealant strip, including Owens Corning’s. The difference we see is that Owens Corning’s architectural lines have a heavier mat that holds granules longer, but the sealant still gets brittle after 12 to 15 years. We recommend checking sealant adhesion every few years on any Owens Corning roof older than a decade. Call (866) 321-6172 and we’ll do that as part of a roof inspection.
Yes, and that’s common in Northridge. Valley heat dries out flashings and vent boots faster than the shingles around them, so a leak at a vent pipe or a valley is often a flashing failure, not an Owens Corning shingle failure. We’ll replace the flashing or boot with a quality aftermarket equivalent and leave the shingles alone if they’re still sound. That’s a smaller repair than a shingle replacement, and we’ll recommend it when it’s the honest fix.
