Owens Corning Roofing in Pomona, CA | Orange County Roofing Co
Owens Corning roofing service in Pomona means working on two very different roof decks on the same street: hand-nailed plank sheathing from the 1920s and skip-sheathing from the 1960s. We’re an independent roofing contractor, not an Owens Corning manufacturer affiliate, and we install, repair, and replace their shingle systems across every Pomona ZIP from 91766 to 91769. If you need a straight answer on whether your Owens Corning roof can be repaired or is ready for replacement, call (866) 942-4187.
What makes our Owens Corning work here different is that we read the manufacturer’s installation specs and ventilation requirements line by line, then apply them to what’s actually under your shingles. Pomona roofs don’t fail the way coastal roofs do. They fail from heat soak, UV cycling, and Santa Ana wind stress. For a deeper look at how we approach Owens Corning sales & service across the region, that page covers the full picture.
Why Pomona Residents Choose Us for Owens Corning Service
We’ve spent years pulling apart Owens Corning shingle systems in Pomona, from the Craftsman bungalows near downtown to the mid-century tracts in 91766 and 91767. That matters because the same shingle performs differently on a plank-sheathed deck than on skip-sheathing with air gaps between boards. We know which failure patterns show up where, and that knowledge changes what we recommend.
Our parts approach is simple: genuine Owens Corning shingles, ridge caps, and accessory components when a repair needs to match or a warranty is in play. But we’ll also use proven aftermarket underlayment, flashing, and vent boots where they genuinely outperform the OEM accessory. Owner Kurt Hensley grew up watching roofing crews in Orange County, provides Owens Corning service in Walnut, and has spent two decades on roofs before starting Orange County Roofing Co. His approach: a roof shouldn’t be a mystery – let’s just look at what you’ve got and go from there. We carry seven major brands including Owens Corning, so our recommendation is based on what your Pomona roof actually needs, not what’s easiest for us to sell.

Common Owens Corning Roofing Problems We Solve in Pomona
Here’s what we see repeatedly on Owens Corning roofs in this city, and what’s usually behind it:
- Granule loss and edge curling on south and west slopes. The 100°F-plus inland summers bake the shingles that face the afternoon sun. In the 91766/91767 tracts, we regularly find 3-tab and older Oakridge roofs shedding grit into gutters while the north slope still looks nearly new. This is UV cycling at work, not a manufacturing defect.
- Wind-lifted shingles and loose ridge caps at the foothill edge. Santa Ana wind events funnel down from the San Gabriel Mountains and peel back tabs that lost their seal. Loose ridge caps are often the first thing homeowners notice after a wind event in the northern part of Pomona.
- Seal-strip failure on older Duration roofs. Poor attic ventilation lets heat build up and cook the asphalt sealant before the shingles reach their rated age. We see this on homes where the original builder skipped ridge vents or the soffit intake is blocked.
- Dry-rot around wood fascia and plank sheathing on pre-war bungalows. Downtown Pomona’s early-1900s homes often have original fascia that’s been exposed to decades of leaky flashing. When we pull back shingles near a rotted eave, the problem underneath is usually older than the shingles on top.
- Flat and low-slope porch and garage roof failures. Lots of Pomona homes have flat porch roofs and detached garages with modified bitumen or old roll roofing that’s failing. These aren’t shingle jobs, and we handle them as part of the full roof picture.
Owens Corning Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the thing most roofing pages never connect: Pomona sits at the foot of the San Gabriel Mountains, and that geography creates a specific set of conditions for any asphalt shingle. The inland-valley heat is more punishing than coastal LA, with summer highs routinely over 100°F. The Santa Ana winds funnel down through the passes and hit the foothill edge of the city first. And the dry heat makes attic ventilation a front-line concern, because radiant heat load accelerates the breakdown of the asphalt sealant strips that keep Owens Corning shingles locked together.
What does that mean for an Owens Corning roof in Pomona specifically? It means the south- and west-facing slopes in the 91766/91767 tracts age years ahead of the north slopes. It means wind-driven debris and Santa Ana gusts stress ridge assemblies near the foothill edge of the city. And it means attic ventilation isn’t a nice-to-have: it’s the difference between a Duration roof reaching 30 years and seal strips failing at 12. We inspect for these conditions on every Pomona roof we touch, because fixing the shingle without fixing the heat load is just buying time. Kurt Hensley has seen too many properly installed roofs in Pomona fail early because the attic never got enough airflow.
Owens Corning Models & Products We Service in Pomona
We work on the full Owens Corning residential line. That includes Oakridge and Oakridge TruDefinition architectural shingles, Duration and Duration Designer architectural shingles, the older Supreme 3-tab shingles still found on many Pomona tract homes, and their underlayment products like WeatherLock and ProArmor synthetic. When a repair requires matching shingles or ridge caps, we source genuine Owens Corning components so the repair blends and the warranty stays intact. For underlayment, flashing, and vent boots, we stock what’s proven to hold up in Pomona’s heat and wind, including aftermarket options where they outperform the OEM accessory. Fast turnaround on common components means we don’t leave a torn-off roof exposed any longer than necessary.

AfterOwens Corning Service Pricing in Pomona
Owens Corning shingle work in Pomona varies by what’s underneath the shingles and how much deck repair the job needs. A repair on a wind-lifted slope typically runs less than a full replacement, while a complete tear-off on a skip-sheathed 1960s tract home costs more because we’re usually adding decking over the gaps before the first shingle goes down. Here’s what we typically see in this market:
- Shingle or flashing repair: $350 to $900, depending on slope access and extent of wind or leak damage
- Full tear-off and Owens Corning architectural re-roof: $12,000 to $22,000 on a typical Pomona ranch or bungalow, before any deck replacement
- Deck repair or overlay on skip-sheathing: $1,500 to $3,500, depending on how much of the old decking has gaps or rot
- Flat porch or garage roof replacement: $2,000 to $5,500, depending on size and membrane choice
Every estimate is free and line-itemed, so you see exactly where the money goes. Call (866) 942-4187 and we’ll walk the roof with you and give you a written number.

FAQs – Owens Corning Roofing in Pomona
Because those slopes take the full force of the inland-valley afternoon sun. Pomona’s summer highs over 100°F combined with intense UV exposure break down the asphalt and granules on sun-facing shingles years before the shaded north slope shows any wear. The fix is usually better attic ventilation plus a shingle rated for heat and impact, not just replacing the worn slope.
Yes. A wind-lifted ridge cap or a few lifted tabs after a Santa Ana wind event in Pomona is usually a repair, not a replacement. We re-seal the tabs, replace damaged ridge caps with matching Owens Corning components, and check that the underlying fastening is sound. Call (866) 942-4187 and we’ll tell you honestly whether it’s a patch job or something bigger.
Usually no. Skip-sheathing has gaps between the boards, and architectural shingles need a solid nailing surface. We typically overlay new decking over the gaps before installing the shingles. It costs more up front, but it prevents shingles from sagging into the gaps and failing early. We’ll show you what’s under there before we quote the job.
For most Pomona homes, we recommend Duration architectural shingles with a proper ridge vent and adequate soffit intake. Duration’s SureNail strip and heavier construction hold up better to both the UV cycling and Santa Ana wind stress we get here. If your roof has a low slope or you’re on a tight budget, we’ll talk through the trade-offs honestly. Call (866) 942-4187 for a free estimate.
We handle both. Many Pomona bungalows and tract homes, plus properties needing Owens Corning in Covina, have flat or low-slope porch roofs, garage roofs, and patio covers that need modified bitumen or TPO rather than shingles. We inspect those as part of the overall roofing picture, so you don’t have to call a separate contractor for half your roof.
