Owens Corning Roofing in Century City, CA | Barnwood Roofing
Owens Corning roofing in Century City means commercial low-slope work, not house shingles.

If you manage or own a building in Century City and need an Owens Corning system assessed, repaired, or replaced, call (855) 382-1073 for a free estimate.
Why Century City Property Managers Choose Us for Owens Corning Service
Barnwood Roofing is not a single-brand shop. We work across seven manufacturers, GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, which means when we recommend an Owens Corning system or a repair on one, it’s because the building’s condition and budget point there, not because we’re tied to one label. We read Owens Corning’s published specifications for TPO, modified bitumen, and Duration shingles and install to those specs. No manufacturer authorization behind us, no partnership, no warranty endorsement from Owens Corning. Just a crew that knows the assemblies line by line.
Ruben Calloway, our owner, came up through Chaffey College’s construction technology program and spent years on commercial and residential roofs across the Inland Empire before starting Barnwood. His rule on every job, Century City tower deck or condo podium, is the same: “Tell me what the roof actually needs, then we’ll talk about what it costs.” That’s why roof inspection is a standalone service with us. We’ll tell you if a repair is enough.

Common Owens Corning Roofing Problems We Solve in Century City
- Seam and lap failures at parapets and drains. Marine-layer dew settles on large low-slope decks overnight, and the morning moisture pools where Owens Corning TPO and modified bitumen sheets lap at parapets, drain collars, and curb flashings. Years of ponding push water into those seams. Leaks show up at the edges first, not in the field.
- UV-baked cap sheets and shingles. Century City gets intense sun with long dry spells. Owens Corning membrane cap sheets and shingle surfaces lose granules and sealant strips to UV over time, then crack and burn out. The roof looks tired for months, then the first winter storm finds every weak point at once.
- Penetration and curb flashing failures. Tower roofs and podiums along Avenue of the Stars and around Century Plaza carry HVAC arrays, cooling towers, solar, and screened mechanical penthouses. Every unit means another curb flashing where the Owens Corning membrane gets cut and re-terminated. Those dozens of details are where most leaks start.
- Wind-peeled ridge caps and rake edges. On the few pitched accent roofs under Owens Corning shingles, wind channeling between towers peels ridge caps and rake edges before field shingles show any wear. The field looks fine; the edges fail first.
- Ponding at drain collars on retail podiums. Century City Mall and similar retail decks are big flat expanses with drains that clog or settle. Owens Corning cap sheet checks and cracks around those collars when water sits, and the leak travels sideways before it shows inside.
Owens Corning Service in Century City: What Local Conditions Mean for Your Roof
Century City is a 176-acre master-planned business district built on the old 20th Century Fox backlot. Essentially none of it is single-family housing. Every Owens Corning job in 90067 lands on a commercial low-slope or terrace assembly: tower roofs, podium decks, retail caps, the condo high-rises near the twin Century Plaza towers. That changes how a roofer has to think. The roof is not just weather protection here; it’s the platform for HVAC arrays, cooling towers, solar racks, and screened mechanical penthouses. A re-roof on an occupied office tower means phased work, crane-and-rigging logistics, and coordination around tenants who cannot lose a workday to a tear-off. On a mid-rise along Avenue of the Stars, our crew traced interior staining to a seam at the base of a unit curb on an Owens Corning TPO deck, similar to Owens Corning repair in Santa Monica projects we handle. We heat-welded a new lap, re-terminated the flashing, and phased the patch around occupied floors below. No one lost a workday. That’s what Owens Corning service in Century City actually looks like.
Owens Corning Models & Products We Service in Century City
We work on Owens Corning Duration architectural shingles, Supreme 3-tab composition shingles, TPO single-ply membrane, modified bitumen cap and base sheet, and WeatherLock underlayment. On commercial decks we use genuine Owens Corning membrane and underlayment where the brand’s own system warranty path depends on them, and quality aftermarket flashing, fasteners, and termination bar where Owens Corning doesn’t make the piece. For Century City turnaround we keep common TPO and modified bitumen lap materials, sealants, and termination components stocked locally, so a patch or seam repair doesn’t wait on a distributor order from across the county.

AfterOwens Corning Service Pricing in Century City
What you’ll pay depends on the scope. Seam and lap repairs on an Owens Corning TPO or modified bitumen deck in Century City typically run between $450 and $1,200 per penetration or failed lap, based on access, curb count, and whether we’re working from the roof or need a swing stage or boom lift. Full membrane replacement on a tower or podium deck runs from $8 to $14 per square foot, depending on insulation condition, tear-off depth, and the number of mechanical curbs to flash. A free estimate with us includes a written line-item breakdown, an honest read on whether repair will hold, and no pressure toward replacement when a patch is the right call.

FAQs – Owens Corning Roofing in Century City
Do you install Owens Corning systems on the flat roofs of Century City office towers and condo towers?
Yes. We install and repair Owens Corning TPO and modified bitumen systems on low-slope commercial decks, podiums, and terrace assemblies across Century City, including occupied towers where the job has to be phased around tenants and mechanical equipment.
Can an Owens Corning roof be repaired while our building stays occupied?
Yes. Most seam, lap, curb, and drain-collar repairs on Owens Corning TPO and modified bitumen decks are surface-level and can be completed without tearing off the field membrane or disrupting floors below. We phase the work around occupied tenants and schedule noisy operations, like heat-welding or mechanical lifting, in coordination with building management.
Why does our flat Owens Corning roof leak in winter when summers are dry?
Century City’s long dry summers let UV bake Owens Corning cap sheets, shingles, and sealant strips until they crack and burn out. Then when the first winter storm arrives, water finds every failed seam, lap, and drain collar at once. The roof didn’t suddenly fail in the rain; it failed in the sun and announced it in the storm. If you’re seeing winter leaks, call (855) 382-1073 for a free inspection before the next rain cycle.
Is Barnwood Roofing authorized or partnered with Owens Corning?
No. We’re an independent contractor. We install Owens Corning systems to the manufacturer’s published specifications, and we use genuine Owens Corning membrane, underlayment, and shingle components where the warranty path depends on them. We carry no manufacturer authorization, partnership, or endorsement, and that independence is the point. We recommend what the roof actually needs, not what a brand agreement tells us to sell.
Our condo HOA needs Owens Corning shingles to match a pitched accent roof – can you handle a mixed flat-and-shingle roof?
Yes. Many Century City condominium towers have a flat TPO or modified bitumen main deck paired with a pitched accent roof under Owens Corning Duration or Supreme shingles. We repair and replace both systems on the same building, including the transition details where the shingle roof meets the commercial membrane. Call (855) 382-1073 and we’ll walk the whole roof with you.
