Owens Corning Roofing in Glendale, CA | Marquis Roof Repair
We repair and replace Owens Corning roofing systems across Glendale, from original 1930s barrel tile tear-offs in the Verdugo foothills to flat modified-bitumen patches on south-side apartment buildings. What makes our Owens Corning work different here is simple: we’ve spent over fifteen years watching how Durations, Oakridges, and WeatherLock underlayment actually fail under Glendale’s 100°F summers and Santa Ana wind cycles, so our repairs address the real failure point, not just the visible symptom. Call (866) 705-2978 for a free estimate on any Owens Corning roof concern in Glendale. Marquis Roof Repair is an independent contractor, not an Owens Corning authorized or endorsed installer.
Why Glendale Residents Choose Us for Owens Corning Service
We know Owens Corning product lines the way a mechanic knows a specific engine family: where their sealant strips give up, how their underlayment behaves after repeated thermal cycling, and what actually holds up on a south-facing Glendale slope. That depth comes from installing and repairing these systems across Glendale’s mixed housing stock for years, not from a one-day product seminar. We’re also one of the few local contractors running Owens Corning sales & service alongside six other manufacturer lines, which means our recommendations aren’t tied to what’s sitting in our warehouse. Ron Thibodeau built Marquis Roof Repair on methodical diagnostics after two-plus decades of roofing across the San Fernando Valley, and that’s the standard we hold every Owens Corning job to: we investigate before we recommend. When a valley repair will buy you five more years, we’ll tell you that instead of pushing a full replacement.

Common Owens Corning Roofing Problems We Solve in Glendale
- Wind-blown shingles on south- and west-facing slopes. Owens Corning Duration and Oakridge shingles rely on thermal sealant strips to bond each course. Glendale’s summer heat plus cool overnight temperatures cycles that sealant hard, and once it releases, Santa Ana winds peel shingles from Verdugo foothill roofs with surprising speed. We inspect sealant integrity before wind season, not after shingles end up in your neighbor’s yard.
- Hidden leaks from cracked WeatherLock underlayment. WeatherLock on low-slope transitions and valleys gets brittle after repeated 100°F summers. The leak doesn’t show up until the first real winter storm soaks through. If your Glendale roof leaks only when it rains, the underlayment is usually the culprit, not the shingles you can see.
- Failed underlayment hidden under original barrel tile. North Glendale’s 1920s-40s Spanish Colonial homes often have clay barrel tile over skip sheathing, and prior owners have been known to patch over failing underlayment without ever lifting the original tile. Walking the roof is the only way to find it, and we do that on every Glendale inspection.
- Flashings and skylight curbs that give out before the roof does. Hillside homes above Glenoaks in 91202 and 91208 catch wind-driven rain and ember exposure that cooks sealant and rusts metal at chimney and skylight transitions. Flashing repair is a specialty, and it’s one of the most cost-effective ways to extend an Owens Corning roof’s life in Glendale.
- Blistering modified bitumen on south Glendale flat roofs. Dense 1950s-1970s apartment buildings in 91201 and 91204 bake their flat roofs to failure temperatures every summer. We patch modified bitumen before blisters become full leaks, and we’ll tell you straight when a patch is enough and when the roof needs a full recover.
Owens Corning Service in Glendale: What Local Conditions Mean for Your Roof
Here’s the Glendale-specific truth most roofing pages won’t tell you: in the north-side hillside neighborhoods of 91202 and 91208, it’s routine to find 1930s barrel tile that was never lifted when a previous owner had shingles or underlayment patched over it. What looks like a simple Owens Corning repair in Burbank or Glendale becomes a full tear-off once we walk the roof and expose the original skip sheathing. Last spring, a homeowner on a hillside street above Glenoaks called us about a leak near a valley on their 1930s Spanish Colonial. The previous owner had patched over failed underlayment with Owens Corning Supreme shingles without lifting the original barrel tile, so once we walked the roof we found cracked WeatherLock underlayment and rotted skip sheathing across two valleys. We removed the patch, replaced the decking, installed new Owens Corning underlayment, and reset the original tile – stopping the leak without a full tile replacement. That’s the difference between estimating over the phone and actually walking the roof in Glendale.
Owens Corning Models & Products We Service in Glendale
We work on the full Owens Corning residential and light-commercial product range, including Oakridge architectural shingles, Duration premium architectural shingles, Supreme asphalt shingles, and WeatherLock underlayment systems.

AfterOwens Corning Service Pricing in Glendale
Every Owens Corning service quote in Glendale comes down to what we find once we’re on the roof. A flashing repair around a skylight curb might run a few hundred dollars. Tile underlayment replacement on a 1930s Spanish Colonial, where we lift and reset original barrel tile, lands in a different conversation entirely. Flat roof patching on a south Glendale apartment building prices by square footage and membrane condition. What you’ll always get from us is a written, line-item quote before any work starts, and we’ll explain exactly which Owens Corning products we’re using and why. Call (866) 705-2978 to schedule a free estimate, and we’ll walk your Glendale roof with you if you’d like to see what we see.

FAQs – Owens Corning Roofing in Glendale
Yes. Valley leaks are usually an underlayment or flashing failure, not a shingle defect, and those are exactly the repairs we handle in Glendale every week. Owens Corning’s shingle warranty covers manufacturing defects, not installation or underlayment issues, so we’ll diagnose what’s actually leaking and repair it with materials suited to your roof’s age and exposure. Call (866) 705-2978 and we’ll inspect the valley in question, take photos, and give you a straight answer on repair versus replacement.
In most cases, yes. We lift the original barrel tile section by section, replace the failed underlayment and any rotted skip sheathing, then reset the tile. It’s slower and more labor-intensive than a full replacement, but it preserves the look and material of a 1930s Glendale roof while solving the actual leak. We’ve done this on homes across 91202 and 91208, plus Owens Corning in Echo Park, more times than we can count.
For straight sunlight and heat, we typically recommend Owens Corning Duration architectural shingles. Their SureNail fabric and heavier construction hold up better under thermal cycling than lighter Supreme shingles, and the wider nail zone gives installers more margin on steep Glendale slopes. But the best shingle for your roof depends on pitch, sun exposure, and budget, so we’ll walk it with you before recommending anything — whether that’s here or an Owens Corning repair in Silver Lake.
Usually within a few days of inspection, depending on the size of the blistered area and whether the membrane has cracked through to the substrate. We keep modified bitumen patch materials and cold-process adhesives on hand for Glendale’s older flat-roof stock. Call
