Owens Corning Roofing in Los Angeles, CA | Marquis Roof Repair
We provide independent Owens Corning roofing service across Los Angeles, from inspection and precise shingle repair to full tear-off and replacement. The one thing that makes our Owens Corning work different here is that we know how these shingle lines actually age on LA’s pre-war bungalow stock, where low-slope decks and relentless UV expose failures most roofers never see until water is already inside. If you need someone who reads Owens Corning spec sheets the way a diagnostician reads a chart, call (866) 705-2978 for a free estimate.
Why Los Angeles Residents Choose Us for Owens Corning Service
We’ve torn into enough Owens Corning roofs across South and Central LA to know how their shingle lines age under this city’s sun and how their underlayments behave in a heavy winter rain, from Owens Corning in Koreatown to neighborhoods farther south. As an independent roofer, we read their spec sheets, not their sales scripts, which means we’ll tell you straight when an OC installation is worth repairing versus when the deck behind it has failed. Ron Thibodeau, our owner, learned roofing the slow way: studying building construction technology at Los Angeles Valley College, then spending two-plus decades working roofs across the San Fernando Valley before Marquis Roof Repair put down roots in Burbank. That background matters when a homeowner in Los Angeles calls about curling Owens Corning shingles and wants an honest answer, not a pitch.
We carry and service the full Owens Corning residential line, including Owens Corning sales & service across Los Angeles. Seven manufacturer lines sit on our truck manifests, not just one, so the recommendation you get is driven by your roof, your climate, and your budget. We investigate before we recommend, and we won’t shingle over a deck that’s done.

Common Owens Corning Roofing Problems We Solve in Los Angeles
Los Angeles weather doesn’t punish roofs evenly. Here’s what we repeatedly find on Owens Corning roofs in this city, and why it happens:
- Sun-baked shingles on south- and west-facing slopes. In neighborhoods across South LA and the San Fernando Valley, an Owens Corning Oakridge or Duration roof can lose granules and crack on the hot exposures years before the shaded north side shows any wear. That’s thermal cycling and UV, not a product defect, and it’s repairable if caught before the mat tears through.
- OC architectural shingles lifting over old tar-and-gravel decks. On 1920s-to-1950s bungalows in ZIPs 90001 through 90008, we regularly see new Owens Corning shingle fields spot-crack where the original flat roof wasn’t fully stripped. The old bitumen holds heat and moisture, and the shingle field pays for it.
- Flashing and vent-boot failures at shared parapets. Tight-setback apartment courts and bungalow rows with shared walls put enormous stress on perimeter flashing. When the flashing goes, water tracks back under the Owens Corning shingle field and the leak shows up three rooms away from the source.
- Winter-rain leaks from re-coated flat sections. Many pre-war Los Angeles homes have hybrid roofs: shingles on the pitched front, tar-and-gravel on the back addition. When the flat section ponds after too many re-coats, water saturates the Owens Corning underlayment from below and drips through the ceiling.
- Granule loss concentrated on one exposure. If your Owens Corning shingles are balding on one slope only, that’s a clue about sun path and roof pitch, not a reason to reroof the whole house. We patch the damaged field and match the lot so the repair disappears.
Owens Corning Service in Los Angeles: What Local Conditions Mean for Your Roof
Much of the pre-war single-family stock in ZIPs 90001 through 90008 is low-slope or shallow-pitch, which means an Owens Corning shingle roof here often sits where a flat roof or a hybrid re-roof would have gone. Shingle-grade underlayment gets stress-tested by standing water, not just rain running off. On a bungalow in the 90007 area we got called out to, the south- and west-facing slices of an Owens Corning Oakridge roof had lost their granules and gone brittle years before the shaded north side. The real culprit wasn’t the shingles. A tar-and-gravel section at the back had been re-coated until it ponded and pushed water under the OC underlayment. We patched the flat, replaced the sun-damaged shingle field to match the lot, and reset the flashing at the shared parapet. No more winter-rain drips into the back bedroom. That’s the Los Angeles version of Owens Corning roofing: the shingles are rarely the whole story.
Owens Corning Models & Products We Service in Los Angeles
We work on the complete Owens Corning residential line: Oakridge Architectural Shingles, the Duration Series including Premium and Storm, Supreme and other Class 3 asphalt shingles, and Owens Corning roll roofing and underlayment products used on low-slope LA roofs. When we repair, we match shingle profiles and underlayments by line and color lot so the blend is clean. We also use quality aftermarket flashing and vent boots where they outperform the OEM on parapets and tight lots. Parts are stocked locally for fast Los Angeles turnaround, and our multi-brand access means you’re never locked into one product line because it happened to be on someone’s shelf that week.

AfterOwens Corning Service Pricing in Los Angeles
Owens Corning shingle repair in Los Angeles typically runs $350 to $700 for a targeted patch, while full replacement on an average bungalow roof lands between $12,000 and $22,000 depending on deck condition, pitch, and whether old tar-and-gravel sections need stripping first — similar to what we quote for Owens Corning service in Silver Lake. The biggest cost driver on these pre-war homes is what’s hiding under the shingles, not the shingles themselves. A free estimate with Marquis Roof Repair includes a roof inspection, an honest read on deck condition, and a written line-item quote from Ron’s team. Call (866) 705-2978 to schedule yours, and we’ll show you exactly what needs fixing and what can stay.

FAQs – Owens Corning Roofing in Los Angeles
It can be, but only if the underlayment and flashing details are spec’d for low-slope conditions, not for a steep suburban roof. On shallow-pitch Los Angeles bungalows, we often recommend a hybrid approach that respects the original flat sections rather than shingling over them. Call (866) 705-2978 and we’ll assess your specific pitch and deck before any recommendation is made.
One-sided curling almost always points to sun exposure. The south- and west-facing slopes in Los Angeles take the full brunt of dry-season UV and heat, which accelerates granule loss and thermal cracking in Owens Corning shingles while the shaded side stays intact. We can patch the damaged field and match the existing lot. Call (866) 705-2978 for a free estimate on selective replacement.
Yes, and it’s one of the most common calls we get across Los Angeles. When a re-coated flat section pond water, we strip the failed layers, repair the membrane, and reset the transition flashing where the flat meets the shingle field. Getting that junction right is what stops leaks from chasing under the Owens Corning shingles. Call (866) 705-2978 and we’ll inspect the flat section before quoting anything.
We do, and these are jobs where attention to perimeter flashing matters more than shingle work itself. On Los Angeles apartment courts and bungalow rows with shared parapets, we reset and reseal flashing details first, then repair the Owens Corning shingle field behind them, including Owens Corning repair in Hollywood. Estimates are free. Call (866) 705-2978 to schedule one.
Yes. We match Owens Corning shingles by line and color lot so the repaired section blends with the rest of the roof. On older roofs with faded exposures, we’ll show you what a realistic match looks like before we start. Call (866) 705-2978 for an exact quote on color-matched Owens Corning repair in Los Angeles.
