Owens Corning Roofing in Van Nuys, CA | Marquis Roof Repair
We provide independent Owens Corning roofing service across Van Nuys, from targeted shingle replacement to full tear-offs on the tract homes that define this part of the Valley. What makes our Owens Corning work different here is simple: we know that a 1950s shallow-pitch roof in Van Nuys can’t always take shingles the way a newer build can. If you need someone who understands both the brand and the neighborhood, call (866) 705-2978.
Why Van Nuys Residents Choose Us for Owens Corning Service
Ron Thibodeau grew up in Magnolia Park in Burbank and studied building construction technology at Los Angeles Valley College in Valley Glen. He spent more than two decades doing roofing work across the San Fernando Valley before founding Marquis Roof Repair. When he talks about Owens Corning shingles curling on a Van Nuys roof, he’s speaking from thousands of tear-offs, not a spec sheet.
We work with Owens Corning roofing products every week, which means we’re familiar with how Oakridge, Duration, and the old three-tab Supreme lines actually behave. Our shop stocks common Owens Corning color blends and accessory parts locally so Owens Corning repair in Encino or Van Nuys doesn’t wait on a warehouse order from 300 miles away. We are an independent contractor, not authorized or sponsored by Owens Corning. That independence matters because it means our recommendations are based on what your roof actually needs, not on a quota.

Common Owens Corning Roofing Problems We Solve in Van Nuys
Here’s what we see most often when we get called out to Owens Corning roofs in Van Nuys.
- Granule loss and asphalt embrittlement. Van Nuys summers routinely cross 100°F, and that heat bakes asphalt shingles fast. Owens Corning three-tab and even newer architectural lines shed granules into gutters, turn chalky, and curl at the edges well before the nominal warranty life. We see it on homes all through 91401 and 91405.
- Sealant strip failure and wind-lifted tabs. Duration architectural shingles rely on a heat-activated adhesive strip. When attic ventilation is poor and the underside of the deck cooks, that adhesive fails. Tabs flutter loose in the first strong Santa Ana wind event. A roof that laid flat for years can start lifting in a single afternoon.
- Cracked pipe boots and split vent collars. Owens Corning neoprene boots degrade from UV before the shingles around them let go. In Van Nuys, the boot around a plumbing vent often cracks during the first winter rain after a long dry summer. The shingles look fine, but water runs straight down the pipe to the ceiling below.
- Leaks where hot-mop sections meet shingle fields. On 1940s and 1950s tract homes, the original low-slope sections were hot-mopped. When a prior roof was overlaid with Owens Corning shingles without addressing the underlying membrane, the transition fails and water finds the deck. By the time a ceiling stain shows, the rot has usually been working for a while.
- Premature aging on shallow pitches. Shingles need slope to shed water. A lot of Van Nuys tract roofs sit at angles that hold water longer than shingles are designed to tolerate. The result is accelerated granule loss, curling, and early failure at the eaves.
Owens Corning Service in Van Nuys: What Local Conditions Mean for Your Equipment
In the shallow-pitch postwar tract homes across 91401 and 91405, the original hot-mop asphalt decks are too low-slope to accept Owens Corning shingles directly. That’s the part nobody tells you until the tear-off starts. Many jobs here require a build-up or a low-slope membrane at the perimeter before any shingle goes down. It’s a specific wrinkle of Van Nuys’s mid-century housing stock that changes the entire scope of an Owens Corning replacement. The Valley’s extreme summer heat cycling then works against whatever the last contractor installed: membranes dry out, flashings crack, and shingles that were laid directly over old hot-mop curl within a few seasons. A roof done right the first time is the only version worth doing, and on this side of the 101 that means respecting what these 1950s decks were actually built for.
On a 1951 stucco tract house near Van Nuys Boulevard in 91405, we tore off failed original hot-mop asphalt on the rear low-slope section and found Owens Corning three-tab shingles the prior owner had nailed directly over it. The tabs were curled and shedding granules from the Valley heat. We built up the low-slope deck, laid a membrane at the transition, then installed Owens Corning Duration architectural shingles with new vent boots and flashing. That homeowner has been dry through two rainy seasons since.
Owens Corning Models & Products We Service in Van Nuys
We service the full Owens Corning roofing line you’ll find across Van Nuys and nearby communities: Supreme and Classic three-tab shingles on the older stock, Oakridge and Oakridge Preferred from mid-range replacements, and Duration and Duration Premium architectural shingles on newer work, including Owens Corning service in North Hills. For repairs, we match your existing Owens Corning color and line so a patched section doesn’t read as a patch. Where the existing system is Owens Corning, we use genuine shingles, underlayments, and accessory boots. Where aftermarket flashing or low-slope membrane products outperform the Owens Corning accessory, we spec those instead and tell you why. We’re here to put the right material on your roof, not to hold a brand line.

Shingle replacement on a small patch starts around $350 – $800 depending on access, shingle type, and whether the underlayment is still sound.

FAQs – Owens Corning Roofing in Van Nuys
Often no, at least not directly. The shallow-pitch hot-mop decks on many 1940s and 1950s tract homes in Van Nuys sit below the minimum slope for shingle installation, so a build-up or a low-slope membrane has to go down first before shingles can be laid on the sloped portions. We’ll assess your specific roof and tell you honestly whether an Owens Corning shingle replacement is viable or whether a membrane system is the smarter play. Call (866) 705-2978 to schedule a look.
In Van Nuys, the usual culprit is heat combined with poor attic ventilation. Duration shingles rely on a heat-activated sealant strip, but when the underside of the deck gets too hot and the topside bakes under 100°F summers, the adhesive can fail and tabs begin to curl. It’s rarely a manufacturing defect. Fixing the ventilation is just as important as re-sealing or replacing the affected shingles.
Oakridge is a solid mid-range architectural shingle, and we install them often on Van Nuys tract homes where the slope is adequate. On a 1960s home with fair deck condition and proper slope, Oakridge delivers good value. But the deck condition and slope matter more than brand. We’ll assess your roof first and give you a straight answer about what will actually hold up here.
The neoprene boots on Owens Corning vent pipes crack and split from prolonged UV exposure, which Van Nuys supplies in abundance. A full dry summer can cook a boot to the point that the first winter rain finds every crack. This is a targeted repair we handle routinely, and it’s far cheaper than chasing the leak with a full re-roof. Call (866) 705-2978 for an exact quote, and we’ll check every boot on the roof while we’re up there.
If the roof is past 20 years old on a shallow-pitch tract home, patch-and-repair usually just buys time. The underlying hot-mop section, flashing, and deck have all been cooking in Valley heat for two decades, and patching the visible damage often misses what’s happening underneath. We’ll inspect honestly and tell you if a repair makes sense or if a full tear-off is the only version worth doing. Estimates are free, so call (866) 705-2978 and let us look before you decide.
