Owens Corning Roofing in Glendale, CA | Orange County Roofing Co
We provide independent Owens Corning roofing service across Glendale, from the flatland ranch tracts to the steep Chevy Chase hillsides, and Owens Corning in Echo Park too. The one thing that makes our Owens Corning work different here: we understand how Duration and Oakridge shingles actually behave under Santa Ana wind uplift and hard UV, not just how the datasheet says they should. Call (866) 942-4187 to schedule a free estimate, and we’ll tell you straight whether a repair or a full replacement makes sense for your roof.
Why Glendale Residents Choose Us for Owens Corning Service
Years of tearing into Owens Corning roofs across Glendale taught us something the product brochures won’t mention: these shingles age differently on a steep Verdugo foothills slope than they do on a shaded Owens Corning repair in Burbank ranch. Kurt Hensley, our owner, has spent the better part of two decades on roofs across Southern California, and he built this company on straight answers and clean installs. No materials swapped on the job. No surprise charges.
We carry seven major shingle brands, GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so when we recommend an Owens Corning product, it’s because it fits your roof and budget, not because we’re locked into one manufacturer. We’re an independent contractor, not affiliated with Owens Corning, which means our advice doesn’t come with a brand agenda. We also know our way around OEM-compatible parts: genuine Owens Corning shingles and WeatherLock where the assembly matters, quality aftermarket boots and edge metal where a factory stamp adds nothing but cost. Check our full Owens Corning sales & service page if you want to see how we approach the brand across our territory.

Common Owens Corning Roofing Problems We Solve in Glendale
- Wind uplift at ridge caps and rake edges. Santa Ana gusts rip through Glendale’s canyons and peel caps and starter courses before the field shingles show any wear. We see this most often on Chevy Chase and Glenoaks Canyon homes where the roofline faces the wind corridor. A failed ridge cap isn’t a full roof problem, and we’ll repair the failed plane rather than sell you a tear-off.
- Heat-cracked and granule-starved shingle fields. South- and west-facing slopes in Glendale bake under intense UV for six months a year. Owens Corning shingles on those exposures lose granules, crack, and dry out, while the underlayment underneath turns brittle and baked. If you run a hand down a south-facing plane and come back with granules, that’s the Glendale sun doing its work.
- Seal-strip failure and tab lifting. The 1960s-70s ranch tracts on Glendale’s flats were built fast, and many decks are under-ventilated. Shingles on those roofs don’t get the thermal relief they need, so the seal strips let go and tabs lift. It looks like wind damage, but it’s usually a ventilation story.
- Hidden deck failure beneath later shingle layers. On a tear-off, we routinely find old wood shingle or skip sheathing under what looked like a straightforward Owens Corning re-roof. That hidden layer means re-sheathing before any new product goes down, and it changes the budget on the spot. Flatland crews in neighboring Burbank almost never encounter this.
- Underlayment failure under tile and shingle assemblies. Clay tile over aged felt is a Glendale constant, especially on pre-1950s Spanish Colonial homes. When the felt fails, water gets under the tile and the leak shows up inside long before you see anything wrong from the street. We replace the underlayment and put the tile back, often with Owens Corning WeatherLock as the new substrate.
Owens Corning Service in Glendale: What Local Conditions Mean for Your Roof
Glendale’s hillside neighborhoods aren’t just a steeper version of the valley floor, they’re a different roofing market entirely. Chevy Chase, Glenoaks Canyon, and the Verdugo foothills sit on pitches steep enough that every tear-off requires a spider staging system, similar to the Owens Corning repair in Silver Lake hillside jobs we handle. The roofers who work the flats never set one up. We do it routinely. And when we pull up later tile on those hillside homes, what’s underneath tells the story of the house: original 1920s-30s wood shingle layers still nailed to the deck, skipped over by whoever installed the next roof decades ago. That stacked-roof condition changes the whole job. You can’t put new Owens Corning product over a hidden wood shingle layer and expect it to perform. You strip to sheathing, re-deck the bad boards, and rebuild properly. The steep pitch also drives how we detail ridge and eave edges, because a Santa Ana gust on a Chevy Chase roofline hits with more force than the same gust on a Burbank street. Ember-resistant ridge and eave detailing matters here too, since Glendale’s wildfire insurance landscape forces homeowners to document ignition-resistant roof assemblies. A generic roof contract won’t satisfy an insurer in the 91201 hillside ZIP codes.
Owens Corning Models & Products We Service in Glendale
We work with the Owens Corning product lines most common on Glendale roofs. Duration architectural shingles, including Duration Storm, show up on newer hillside re-roofs where homeowners wanted Class A fire resistance and a heavier shingle. Oakridge architectural shingles cover a lot of the mid-range re-roofs on the flats and older hillside homes. Supreme 3-tab shingles still hang on some older Glendale tract re-roofs, and we’ll repair those with matching product where the deck is sound. Under any tile or shingle assembly here, we standardize on WeatherLock underlayment when we rebuild, because it handles the intermittent heavy winter rain Glendale gets better than felt.
On parts, we’re pragmatic: genuine Owens Corning shingles and WeatherLock where the assembly is being rebuilt, quality aftermarket boots, vents, and edge metal where the factory option adds nothing but cost. That keeps repairs sensible for Glendale homeowners instead of padding a parts bill for brand purity. If you’re in the Alondra Park area, our Owens Corning service in Alondra Park page covers what we see on those roofs specifically.

AfterOwens Corning Service Pricing in Glendale
An Owens Corning shingle repair in Glendale typically runs $380 to $850, depending on what’s actually failed. A full re-roof with underlayment replacement on a hillside home usually lands between $12,500 and $22,000, and the steepness of the lot, the hidden deck condition, and whether we’re re-sheathing drive the number. A wind-hit ridge on a Chevy Chase home might cost $550 to fix. A tile underlayment replacement, where we lift the tile, re-felt with WeatherLock, and re-set, runs from $6,500 to $15,000 depending on roof size and pitch.
The free estimate we give you includes a written breakdown of what we found, what we recommend, and what each piece costs. No change orders hiding in the fine print.

FAQs – Owens Corning Roofing in Glendale
No. We see this constantly on Chevy Chase homes: a tile layer sitting over original 1920s-30s wood shingles, with no underlayment between them and the deck. Re-covering over that hidden layer means the new Owens Corning roof inherits every problem underneath. We strip to sheathing, re-deck the bad boards, and then install the new assembly properly. Call (866) 942-4187 and we’ll tell you what’s under your tile before you spend a dollar.
Yes, heavily. Glendale hillside homes in the 91201, 91222, and 91225 ZIP codes sit in wildfire-risk zones where insurers expect documented Class A ignition-resistant roofs. Owens Corning Duration and Oakridge architectural shingles meet Class A fire ratings, but the insurer also wants to see the underlayment, ridge, and eave detailing. We document every ignition-resistant component we install so your carrier gets what they need. Call (866) 942-4187 and ask us how to build a roof your insurer will sign off on.
The ridge cap and starter courses on Glendale hillside homes take the full force of the Santa Ana corridor. If the caps were nailed on a steep pitch without enough fasteners or the rake edge wasn’t detailed for wind uplift, the caps peel before the field shingles show any wear. We repair the failed plane, re-set the caps with proper fastening, and leave sound Owens Corning shingles in place. You don’t need a whole roof for a ridge problem. Call (866) 942-4187 and we’ll look at what’s actually lifting.
We lift the tile, remove the failed felt, inspect the deck, and install new underlayment, typically Owens Corning WeatherLock, then re-set the original tile. The process keeps your tile looking like it always has but gives you a waterproof, documented substrate underneath. On Glendale’s pre-1950s Spanish Colonial homes the cost runs $6,500 to $15,000 depending on roof size and access. Call (866) 942-4187 for an exact number after we see the roof.
That’s classic under-ventilated deck failure. The 1960s-70s Glendale ranch tracts were built with minimal attic ventilation, and the shingles and underlayment on those decks have been cooking from below for fifty years. The shingles can look presentable while the underlayment beneath them has cracked and let water through during heavy winter rain. We’ll inspect the deck and tell you whether it’s a patch or a re-roof. Call (866) 942-4187 and we’ll trace the leak to its source.
