CertainTeed Construction in Ontario, CA | Penhallow Remodeling Riverside
We provide independent CertainTeed installation and repair across Ontario, CA, and the one thing that sets our work apart here is knowing how these materials actually behave in this specific city. Landmark shingles, Cedar Impressions siding, ProRoc drywall, FlintBoard plaster base: all of them perform differently under Ontario’s 100°F summers, Santa Ana winds, and older slab foundations than they do in coastal cities. Our crews have spent years working on Ontario’s 1950s stucco ranches, 1970s apartment complexes, and new tilt-up warehouses, so we understand what these buildings need before we quote a number. We’re not a manufacturer-authorized service provider, and we don’t pretend to be. We’re our General Contractor in Ontario, installing and repairing CertainTeed systems properly. Call (341) 895-1170 for a free estimate.
Why Ontario Residents Choose Us for CertainTeed Service
Trevor Nash, our owner, came up through the trade program at Los Angeles Trade-Technical College and has spent the better part of two decades working construction across the Inland Empire. That experience means he’s seen what happens to CertainTeed products when they’re installed without accounting for Ontario’s specific conditions. Our crews work with CertainTeed sales & service materials daily, so we know the product lines, the failure modes, and the right way to handle them. We use exact-match CertainTeed components when color and profile matching matter. For structural underlayments and accessory materials, we’ll use code-compliant aftermarket products when the OEM price doesn’t make sense for your budget. And we always tell you which is which, in writing, before any work starts. That’s the Kingswell Way, and it’s been our standard since 2004. A live person answers our phones 24/7, and every technician arrives background-checked and in uniform. You’ll know exactly who’s walking onto your property.

Common CertainTeed Construction Problems We Solve in Ontario
- Landmark shingle granule loss on south-facing slopes. Ontario’s summer sun is relentless, and roofs facing south take the worst of it. Granules bake off over time, leaving the asphalt substrate exposed to UV breakdown. We see this constantly on older Ontario homes, especially along the Euclid Avenue corridor where original roofs from the 1960s are still hanging on.
- Cedar Impressions siding warping at butt joints. Santa Ana winds pull moisture out of everything, and siding installed without proper expansion gaps will warp at the seams. This shows up most often on the 1970s-era homes that line Ontario’s older neighborhoods, where siding was frequently nailed too tight against the original stucco.
- ProRoc drywall paper delamination. Ontario’s temperature swings between scorching days and cool nights put real stress on uninsulated interior walls. In older homes without proper wall insulation, the paper face on drywall can separate from the gypsum core, leaving bulges and peeling paint.
- FlintBoard plaster base cracking and key failure. Ontario sits on expansive clay soil, and slab foundations move with moisture changes. That movement transfers up through walls, cracking plaster and breaking the keys that hold FlintBoard in place. We see this in the 1950s and 60s single-family homes throughout the city’s core.
- Flashing failures at roof penetrations. Pipe flashings and chimney flashing are the first things to fail on Ontario roofs. The combination of extreme heat expansion and occasional heavy winter rain works seals loose. On a 1962 stucco ranch near Euclid Avenue, we found the original Landmark shingles had lost nearly all their granules and were leaking at the pipe flashings. That roof got a full replacement, not a patch job.
CertainTeed Service in Ontario: What Local Conditions Mean for Your Equipment
Here’s something most contractors from Rancho Cucamonga or Fontana won’t flag for you. Ontario’s historic downtown and the Euclid Avenue corridor contain a significant number of unreinforced masonry buildings. Before any CertainTeed roofing or drywall renovation can be permitted on these structures, the city requires specialized seismic retrofitting and foundation bolting. A roofer who doesn’t know Ontario’s permit triggers might quote you a roof replacement and then hit a wall at the building department. We’ve navigated this process. We replaced the entire roof on that Euclid Avenue ranch with new CertainTeed Landmark shingles, added a ridge vent and high-temperature underlayment to handle Ontario’s summer heat, and tied the new shear nailing into the home’s recently bolted foundation. The homeowner told us the upstairs bedroom stayed 8 degrees cooler during the next heat wave. That’s the kind of detail that matters when you’re spending real money on a roof.
CertainTeed Models & Products We Service in Ontario
We work with the CertainTeed product lines that show up most often across Ontario service area homes and commercial buildings. That includes CertainTeed Landmark asphalt shingles, the workhorse of Inland Empire roofing. We also install and repair Cedar Impressions siding, which remains popular on Ontario’s older residential neighborhoods for its wood look without the maintenance. ProRoc gypsum board and FlintBoard plaster base round out the interior side of our CertainTeed work. When it comes to parts, we prioritize exact-match CertainTeed components for visible materials: shingles, siding profiles, and drywall where color and texture matching are critical. For underlayments and accessories, we use code-compliant aftermarket alternatives when the OEM price doesn’t justify itself. And when a CertainTeed line is severely degraded or discontinued, we’ll tell you straight that a full replacement beats repeated patches.

FAQs – CertainTeed Construction in Ontario
CertainTeed’s manufacturer warranty covers the shingles themselves against defects, but installation workmanship is covered by the installer’s warranty, not the manufacturer’s. We provide our own written guarantee on every project, including our 365-Day Done Right Promise. If something fails inside that guarantee period, we come back and fix it at no charge. Call (341) 895-1170 and we’ll walk you through exactly what’s covered.
Warping at butt joints almost always comes down to installation without proper expansion gaps. Santa Ana winds dry siding out fast, and if the material is nailed tight against the substrate, it has nowhere to move when it expands and contracts. We install Cedar Impressions with the manufacturer’s required expansion clearances and use proper nailing patterns, which prevents the problem. If your existing siding is warping, call (341) 895-1170 and we’ll tell you whether it can be repaired or needs replacement.
If the shingle line is still in production, we can source exact-match CertainTeed Landmark shingles in the same color. If the line has been discontinued or the existing shingles have faded significantly from Ontario sun, a patch will show. In that case, we’ll tell you honestly whether a repair makes sense or whether a full replacement is the better financial move. A free estimate gives you that answer in writing.
If your home is in Ontario’s historic downtown or along the Euclid Avenue corridor and was built with unreinforced masonry, yes, the city will likely require seismic retrofitting before permitting any substantial renovation. We’ve navigated this process on multiple Ontario projects and can tell you early in the estimate whether it applies to your property. Call (341) 895-1170 and we’ll check the address.
Bathroom Remodeling in Ontario is another specialty, and ProRoc works well for garage conversions when installed with proper insulation and ventilation. Ontario’s temperature swings between hot days and cool nights mean uninsulated walls will stress drywall over time, so the installation details matter more than the brand itself. We use ProRoc with the right vapor barrier and insulation for Ontario’s climate, and we price garage conversions between $30000 and $80000 depending on square footage and finish level. Call (341) 895-1170 for an exact quote.
