Why Ontario Residents Choose Us for Owens Corning Service

Owens Corning makes a solid shingle, but a shingle is only as good as the roof it’s nailed to. That’s where our local experience matters. We’ve installed and repaired Oakridge shingles on hundreds of Ontario homes, from 1960s ranch houses in the 91761 ZIP to newer developments near the 91764 corridor. We stock OEM Owens Corning shingles and underlayments, so a repair looks and performs like the original roof. When we’re fixing wind damage or granule loss, we don’t patch with whatever’s on the truck. We match the product to what’s already on your roof.

Rick Sondermann, who owns Polaris Contractors, spent nearly three decades building and renovating homes along the Southern California coastline before bringing that same standard to the Inland Empire. His father was a finish carpenter who believed in doing things once, and that’s the approach our crews take on every Owens Corning job in Ontario and on our San Antonio Heights Owens Corning service calls. We’re independent, which means we work for you, not a manufacturer’s warranty department. That independence lets us recommend a repair when a repair is honest, and a replacement when it’s not.

Common Owens Corning Construction Problems We Solve in Ontario

• Granule loss on south-facing slopes. Ontario’s summer sun is relentless, and we regularly see Oakridge roofs losing granules faster on the south and west exposures. The UV here breaks down the asphalt layer faster than coastal climates, and once granules go, the shingle’s protection is compromised. We’ll check granule loss during any inspection and tell you honestly where your roof stands.
• Wind-lifted shingles after Santa Ana events. The Santa Ana winds that whip through the Inland Empire can lift shingles along gable ends and eaves. In Ontario’s 91761 ZIP, we replaced a wind-damaged Oakridge roof on a 1960s ranch where the gable end had lifted shingles. We upgraded the underlayment to Owens Corning’s high-temp product and installed reinforced starter strips. The homeowner added new gutters for winter rains, and we finished in three days.
• Adhesive failure from high attic heat. Ontario summers push attic temperatures well past 140°F. When a roof doesn’t have enough ventilation, that heat transfers through the deck and breaks down the shingle adhesive strip. Shingles start to flutter. We check your attic ventilation as part of every roof service, because a new Owens Corning roof on a poorly vented attic is just a shingle donation to the wind.
• Premature aging from thermal cycling. Ontario’s temperature swings – hot days, cooler nights – cause constant expansion and contraction. Over time, that cycling ages shingles faster than a stable coastal climate. We often find roofs in Ontario that are 12-15 years old but look 20. The fix starts with ventilation and proper underlayment, not just another layer of shingles.
• Roof-to-wall flashing stress from soil settling. This is the one that surprises people. Ontario’s older neighborhoods sit on former citrus groves, and the organic debris and old irrigation lines left in the soil can cause settling over time. When a foundation settles unevenly, the roof-to-wall connections shift, and flashing details that were once watertight can open up. We check those connections on every Owens Corning service call in the older ZIPs.

Owens Corning Service in Ontario: What Local Conditions Mean for Your Equipment

In the 91764 ZIP, many postwar homes were built directly on former citrus groves. The old irrigation lines and organic material decomposing underground create pockets of soft soil that settle unpredictably. For an Owens Corning roof, that settling translates into stress at the roof-to-wall intersections, where flashing and step flashing absorb movement they were never designed to handle. We’ve seen homes in this area where the shingles look fine from the street, but the flashing details have pulled away enough to let water in during winter rains. That’s why our Owens Corning installations in Ontario’s older neighborhoods always include a structural check of the roof-to-wall connections before we lay the first shingle. If the fascia or rake board has moved, no shingle in the world will keep water out. Ontario’s building inspectors know this too – they’ve been scrutinizing ADU and addition projects closely, and they often require additional drainage and soil documentation. We plan for that from day one.

Owens Corning Models & Products We Service in Ontario

We work primarily with Owens Corning’s Oakridge line, which is a solid architectural shingle for Inland Empire conditions. We stock OEM Oakridge shingles and Owens Corning underlayments for repair work, so color and texture match the existing roof. For accessories like vents, ridge caps, and flashing, we’ll use OEM when the job calls for it, but we also use high-quality aftermarket components when they meet or exceed Owens Corning specs at a better price. We tell you which is which and why. Our position is simple: if your roof has years of life left, we’ll recommend a targeted repair. If a full replacement is the honest answer, we’ll spec the right Oakridge product for your home’s orientation, ventilation, and Ontario’s climate, and install it to the manufacturer’s specification and ours.
