Owens Corning Roofing in Florence-Graham, CA | Van Nuys Roofing Co
We provide independent Owens Corning roofing service across Florence-Graham, from full tear-offs to targeted shingle repairs and flat-roof patches. The one thing that makes our Owens Corning work here different is that we plan every job around the tight lots, shared driveways, and power lines that define this neighborhood. If your Owens Corning roof is granule-stripping on a sun-baked west slope or leaking at a valley, call (866) 321-6172 for a straight answer and a free estimate.
Why Florence-Graham Residents Choose Us for Owens Corning Service
We’ve torn off and repaired Owens Corning shingle systems and flat-roof assemblies across South LA for long enough to know how their mat and granule blends behave under the basin’s relentless sun, and we’ve provided Owens Corning in South Gate with the same level of care. Rick Dominguez, our owner, learned roofing through the construction technology program at Los Angeles Valley College and spent the better part of two decades on rooftops before starting Van Nuys Roofing Co. His rule is simple: “If it doesn’t need replacing, I’m not going to tell you it does.”
We’re an independent contractor, not authorized, sponsored, or warranty-endorsed by Owens Corning. We buy their products because they hold up in Florence-Graham’s climate, not because of a badge. That independence means we inspect first and recommend second. We also carry genuine Owens Corning shingles, underlayment, and matching accessories for field repairs, so patched slopes age with the rest of the roof instead of looking like a mismatched afterthought.

Common Owens Corning Roofing Problems We Solve in Florence-Graham
- Duration Series granule loss on sun-baked slopes. On the south- and west-facing slopes of 1920s – 40s bungalows, the seal strips bake loose and granules strip faster than the rest of the roof. From the ground it looks fine. Up close, the tabs are bare and wind-driven winter rain wicks underneath. We see this constantly in Florence-Graham.
- Soft skip sheathing under old Supreme courses. Original 1920s – 40s wood-frame bungalows often still have skip sheathing. Where a prior leak pooled, that sheathing goes punky. A nail-over on soft decking is a bad bet, so decking replacement becomes part of the tear-off instead of a shingle-only job.
- Ponding shingles on low-pitch fourplex roofs. The 1950s – 60s stucco fourplexes across Florence-Graham often carry Owens Corning shingles laid below their design slope. Water ponds at the seams, flashing rusts, and that’s where most leak calls start. Shingle replacement and flat-roof patching both come into play here.
- Cracked vent boots and old flashing collars. VentSure-style vents and their flashing collars dry out and crack in year-round UV. Water tracks down the vent boot even after the field shingles were replaced. We replace boots and collars as part of the repair, not as an afterthought.
- Hand tear-off realities on tight lots. Along Graham Avenue, power lines run directly over the roofline and shared driveways only fit a single dumpster. That means most Owens Corning tear-offs in Florence-Graham are done by hand with bagging and carried out, never with a conveyor. It’s slower, but it’s the right way to work these lots.
Owens Corning Service in Florence-Graham: What Local Conditions Mean for Your Equipment
On the tight lots along Graham Avenue, power lines cross directly over rooflines and shared driveways are only wide enough for a single dumpster. For Owens Corning tear-offs in Florence-Graham, that means a hand-crew approach: shingles stripped by hand, bagged, and carried out rather than run on a conveyor. It’s not a shortcut. It’s the only safe way to work when you can’t stage heavy equipment and a dumpster-plus-conveyor simultaneously. This also means we schedule tear-offs with a smaller crew footprint and plan staging in the street or front yard carefully. On a 1940s wood-frame bungalow off Graham Avenue, our crew stripped two layers of aging Owens Corning Supreme shingles by hand and bagged them out because the shared driveway couldn’t stage a dumpster-plus-conveyor. Underneath, the original skip sheathing was punky around a long-running valley leak, so we replaced that decking, re-flashed the valley, and finished with Duration shingles on the sun-beaten west slope. That’s the combination of Owens Corning product knowledge and Florence-Graham lot reality we bring to every job here.
Owens Corning Models & Products We Service in Florence-Graham
We work on the full Owens Corning residential lineup: Duration Series and Duration Designer architectural shingles, Oakridge architectural shingles, and Supreme / Supreme AR asphalt shingles. We also service and install Owens Corning WeatherLock underlayment and VentSure ventilation accessories. For field repairs, we use genuine Owens Corning shingles and underlayment so the repaired slope ages with the rest of the roof. Where OEM isn’t the weak point, flashing, vent boots, and collars, we use quality aftermarket parts that hold up better in Florence-Graham’s UV and winter rain. Shingle replacement, flat roof patch, and roof decking replacement are the three services that come up most on this page, and we handle all three in-house.

AfterOwens Corning Service Pricing in Florence-Graham
What you’ll pay depends on what we find on the roof. A targeted shingle repair on a Florence-Graham bungalow typically runs lower than a full tear-off where decking replacement and hand-bagging come into play. Hand tear-off on shared driveways adds labor compared to a conveyor job at a wider-lot home in another city, there’s no getting around that, though our Owens Corning in Huntington Park clients with similar lot constraints see comparable timelines. But the price is the price: we give written, line-item estimates before work starts, with no change orders once we’ve walked the roof. A flat roof patch on a fourplex is priced by square footage and the condition of the existing membrane and flashing. Call (866) 321-6172 to schedule a free estimate, and we’ll climb up, look, and tell you exactly what’s needed and what can wait.

FAQs – Owens Corning Roofing in Florence-Graham
Rarely. Most 1920s – 40s bungalows here still have original skip sheathing, and where a prior leak pooled, that decking is soft. Nailing new Owens Corning shingles over soft decking means the new roof fails early because the nail base is rotten. We’ll tell you if a nail-over works on your specific roof, but if the decking is punky, replacement is the cheaper long run. Call (866) 321-6172 for an inspection and an honest answer.
Most South LA fourplexes from the 1950s and 60s were built with very low slopes, sometimes below what shingles are designed for. When Owens Corning shingles are laid below their design slope, water doesn’t drain fast enough, so it ponds at the seams and finds its way under. The fix is usually roof decking correction, a membrane system on the low-pitch sections, or re-sloping. It’s not a shingle problem, it’s a slope problem.
Usually not. Shared driveways along Graham Avenue are often only wide enough for a single dumpster, which means we can’t stage a dumpster plus a conveyor, a challenge we also solve with Owens Corning service in Walnut Park. Our crews tear off by hand and bag the old shingles, then carry them out. It’s slower and more labor-intensive, but it’s the only safe way to work these lots. We’ll explain the plan and the labor cost before we start, so there are no surprises.
Not always. On sun-baked south- and west-facing slopes in Florence-Graham, Duration shingles can granule-strip and seal-strip bake loose while the rest of the roof still has years left. It depends on how much mat is exposed and whether the tabs are still sealed. We inspect first and tell you if a localized patch will buy years or if the slope is done. Call (866) 321-6172 for a straight read.
We’re an independent contractor, not authorized or warranty-endorsed by Owens Corning, so we don’t process their warranty claims directly. What we do is install and repair Owens Corning products correctly, and we can help you understand what your manufacturer warranty covers and how to file a claim if a product defect is the issue. If it’s an installation or weather problem, we’ll tell you that too.
