Owens Corning Construction in Pomona, CA | Square One Builders
We provide independent Owens Corning roofing installation and repair across Pomona as a general contractor, not a manufacturer affiliate. The difference here is simple: in Pomona’s older housing stock, an Owens Corning replacement usually requires more than shingles. We plan for deck sheathing, ridge venting, and the unvented attics that come standard in pre-1950 bungalows. Call (877) 688-9930 for a free roofing estimate.
Why Pomona Residents Choose Us for Owens Corning Service
We have spent close to three decades working on homes throughout Southern California, and Brent Calloway, our owner, learned framing and finish work through the Construction Technology program at Golden West College before putting in years on the ground. What that gives Pomona homeowners is an Owens Corning contractor who can read a roof deck before the first bundle gets lifted. We spec Owens Corning as an independent general contractor, so we match the shingle line to each roof’s pitch, sun exposure, and budget instead of defaulting to one product. Our crews work almost entirely with Owens Corning underlayment, starter strip, and hip-and-ridge cap, which means we know exactly how these systems age under Pomona heat. For a deeper look at how we approach Owens Corning work, visit our Owens Corning sales & service page. This is full-scope work under one contract: deck, ventilation, shingles, gutters, and the flashing details that actually stop leaks. We’re Pomona service area regulars, not a crew that drives in from another county and guesses at the local conditions.

Common Owens Corning Construction Problems We Solve in Pomona
These are the failure modes we see on Owen Corning roofs across Pomona, tied directly to the climate and housing stock here:
- Granule loss on south- and west-facing slopes. Pomona’s inland summers bake shingles for months, and Santa Ana winds then scour the loosened granules. A Duration roof on a west-facing plane in 91767 can shed enough granules in eight years to expose the mat, and that’s a replace-not-patch situation.
- Wind-lifted or creased shingles along ridge caps and rake edges. We see this after every serious Santa Ana event, usually because a previous crew rushed cap nailing or the sealant strip never fully bonded. The roof looks fine from the street, but the windward rake edge is flapping.
- Sealant-strip failure and tab cracking on older Oakridge and Supreme roofs. Roofs that have baked for 20-plus Pomona summers lose their sealant bond. Tabs lift, water gets under, and the deck starts rotting underneath. We usually find this on original roofs in the 1920s-to-1960s housing core.
- Dry rot and delamination at roof-to-stucco and roof-to-siding transitions. The older bungalows in 91766 and 91767 were never ventilated properly, so trapped attic heat breaks down the underlayment and rots the eaves from the inside. A shingle patch here is cosmetic; the transition needs to be rebuilt.
- Skip-sheathing exposure on pre-1950 tear-offs. This is the Pomona-specific one. When we pull an old Supreme or Oakridge roof in the historic core, we routinely find skip-sheathing boards with gaps between them. Current Owens Corning installation requirements demand a solid deck, so the replacement plan has to include re-sheeting before any shingle goes down.
Owens Corning Service in Pomona: What Local Conditions Mean for Your Equipment
In the pre-1950 core around downtown and along Holt and Mission, roof tear-offs routinely expose skip-sheathing and unvented attic cavities under later-added ceilings. Homeowners in 91766 and 91767 often bought these bungalows with updated interiors and painted exteriors, but the attic above the living room ceiling is original: sealed, under-vented, and framed with boards laid in spaced rows. That means an Owens Corning in La Verne replacement in those neighborhoods usually needs far more than new shingles. The deck needs solid sheathing, and the attic needs ridge venting cut in. If you skip the ventilation, the new Duration shingles cook from below exactly the way the old Supreme roof did, and you have shortened the lifespan of your investment. On a 1940s bungalow off Holt Avenue, our crew tore off a worn Supreme roof and found skip-sheathing and a sealed attic with no ridge vent, so the old shingles had cooked from below. We re-sheeted the deck, cut in ridge venting, and installed an Owens Corning Duration system with matched starter and cap, then added new gutters to handle the runoff the old eaves never accounted for. That is the Pomona difference: a shingle quote that does not account for deck and ventilation is a false number.
Owens Corning Models & Products We Service in Pomona
We install and repair the full Owens Corning service in Claremont roofing line as an independent contractor. The models we see most on Pomona roofs are the Oakridge architectural shingle on older homes, the Duration series on newer replacements, TruDefinition Duration on homeowners wanting deeper color and stronger wind rating, and Supreme plain shingles on the original pre-1960 homes. Our parts approach is OEM for the critical system components: Owens Corning starter strip, hip-and-ridge cap, and underlayment. We do not mix generic caps onto a Duration field. On a sound deck with 20-plus years left, we repair and re-flash. Once granules are gone and the mat is exposed, we tell owners straight that replacement beats patching. For specific questions about your current roof, call us and we will walk you through what you are working with.

AfterOwens Corning Service Pricing in Pomona
What you pay depends on whether we are repairing, replacing, or upgrading the deck underneath. Here are the market-calibrated ranges for Pomona:
| Service | Price Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Tile Roof Repair | $600 – $2,500 |
| Metal Roof Installation | $15,000 – $40,000 |
What drives the cost on a Pomona roof is deck condition, attic ventilation, and whether the old roof has one layer or two. A pre-1950 bungalow with skip-sheathing and no ridge vent will land at the higher end because the sheathing and venting are part of the job, not an add-on. A newer tract roof from the 1990s with a sound deck can often reuse the existing sheathing and come in lower. Your free estimate includes a full roof inspection, deck assessment, and a written line-item quote. Call (877) 688-9930 to schedule yours.

FAQs – Owens Corning Construction in Pomona
It depends on the deck beneath the shingles. If the Supreme roof is on a pre-1950 Pomona home, the underlying deck is often skip-sheathed, and a patch will fail because the shingle cannot seal properly. If the deck is solid and the granules are still intact, we can repair and re-flash. But once the mat is exposed and the sealant strips have baked through 20-plus Pomona summers, patching is money spent on a roof that has already failed. Call (877) 688-9930 and we will tell you which situation you are in.
Roof orientation and attic ventilation are the two biggest factors. South- and west-facing slopes in Pomona take the full inland summer sun, and Santa Ana winds scour loose granules off those same slopes. An unvented attic makes it worse because heat builds under the deck and bakes the shingles from below. A well-ventilated roof on a north-facing slope in a newer Pomona tract can last years longer than the same shingle on a west-facing unvented bungalow, which is why Owens Corning repair in Montclair often focuses on ventilation upgrades.
Yes and yes. Pomona requires a permit for a roof replacement, and the city inspects the sheathing and nailing pattern before the shingles go on. We pull the permits, schedule inspections, and make sure the deck passes before we start shingling. That inspection is exactly why a Pomona roof with skip-sheathing cannot be shingled over: the inspector will fail an un-sheeted deck, and so would we, regardless of inspection.
Yes. We stock or source the common Duration colorways for Pomona, and Owens Corning produces consistent color lots, so matching a roof from the last several years is usually straightforward. If your roof is older, some color drift from UV exposure is normal, and we will show you the closest current match before we order. A color-matched section blended at the transition line is almost always better looking than a full replacement when the deck is still sound.
Owens Corning shingle warranties are tied to the property, not the homeowner, so most transfer when the home is sold. There is often a deadline for the new owner to register the transfer, so we recommend checking the warranty terms with Owens Corning after closing. The transferability applies to the shingle warranty; workmanship warranties from the original installer vary. Call (877) 688-9930 if you just bought a Pomona home and want us to assess the roof and check what is still covered.
