CertainTeed Construction in Ontario, CA | Mason Remodeling
We’re an independent CertainTeed service provider handling roof replacement, repair, and metal roofing across Ontario, CA and Rancho Cucamonga. Most Ontario homeowners call us because their CertainTeed shingles have failed in a way that’s specific to this city: thermal cracking from 100°F+ summers, or wind damage from Santa Ana events. Call (803) 680-2547 for a free estimate, and we’ll tell you whether repair or replacement makes sense before you spend a dollar.
Our crews have installed CertainTeed Landmark, Presidential, XT25, and NorthGate roofing systems throughout the Inland Empire for years, so we understand how these products actually perform under Ontario’s specific heat and wind patterns. We’re not authorized by CertainTeed, and we won’t pretend otherwise. What we offer is installation to manufacturer spec, honest repair-versus-replace advice, and a written workmanship warranty. If you’re in Ontario and want a straight answer on whether your CertainTeed roof needs patching or a full tear-off, call (803) 680-2547. We also handle CertainTeed sales & service guidance for homeowners comparing shingle lines.
Why Ontario Residents Choose Us for CertainTeed Service
CertainTeed makes a solid shingle, but the installer matters as much as the product. We’ve torn off enough failed roofs in Ontario to know that two identical CertainTeed Landmark roofs can perform completely differently based on how the underlayment was laid, whether the attic was ventilated, and whether the deck was prepped before the first shingle went down.
Isaac Pruett, our owner, spent years learning framing and finish work at Los Angeles Trade-Technical College before spending nearly two decades remodeling and roofing homes across Southern California. He checks trim work and flashing details the way his dad, a finish carpenter, taught him: slow, close, and personal. When we send a crew from our General Contractor in Ontario, you’ll know exactly who’s coming. Every technician is background-checked and identity-verified under the Threshold Standard, and you get their name and photo before they arrive. They show up in uniform, photo ID badge at the door.
We use CertainTeed OEM shingles, underlayments, and accessories whenever they’re available. For discontinued lines like older Landmark shingles, we source aftermarket matches that meet or exceed ASTM standards. You get a written price before any work starts, and a written guarantee that states exactly what’s covered and for how long: 365 days from the completion date.

Common CertainTeed Construction Problems We Solve in Ontario
- Cupping and cracking on Landmark shingles. Ontario regularly hits 100°F+ in summer, and thermal cycling stresses shingle edges. West-facing slopes absorb the worst afternoon heat, and we routinely see Landmark shingles on west exposures cupping and splitting at the edges within 12 to 15 years. Repairs here mean pulling the damaged tabs and replacing them before water finds the underlayment.
- Lifted and creased Presidential shingles from Santa Ana winds. When Santa Ana winds blow through the Cajon Pass, they hit Ontario with sustained gusts that find every weak adhesive strip. Presidential shingles that weren’t sealed properly, or whose sealant has degraded from years of heat, lift and crease. Once creased, they don’t reseal, and the next wind event peels them off entirely.
- Granule loss on XT25 shingles from attic heat buildup. Poor attic ventilation is common in Ontario’s older tract homes, and it cooks shingles from below. XT25 shingles in particular shed granules fast when attic heat is trapped, exposing the fiberglass mat in 10 to 12 years. By then the roof looks bald in patches and every rain event is a gamble.
- Wrinkling and blistering on NorthGate shingles over uneven decks. Ontario’s pre-1990 tract housing frequently has skipped or uneven roof decking. NorthGate SBS-modified shingles are flexible, but when laid over a wavy deck they can wrinkle and blister, especially along the board seams. We fix this by adding a plywood deck overlay before re-shingling.
- Leaks around flashing at roof penetrations. This isn’t shingle failure, but it’s the most common CertainTeed roof problem we see in Ontario. Vents, pipes, and chimneys flashing rusts and separates over time. The shingles may be fine, but water finds the gap. We replace flashing and boots and reseal the penetration before it rots the decking.
CertainTeed Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s historic downtown corridor is full of pre-1980 homes built with original skip sheathing and minimal attic insulation. Skip sheathing means the deck boards have gaps between them, and that changes everything about how a CertainTeed roof replacement should be done here. You can’t simply lay new shingles over gaps and expect them to handle Ontario’s heat load. The gaps create uneven thermal expansion, which leads to premature cracking, and they weaken the nail-holding surface that shingles depend on during Santa Ana wind events.
In those older Ontario homes, a proper CertainTeed roof replacement typically requires adding a plywood deck overlay first, then upgrading attic ventilation to meet modern heat-resistance standards. For homeowners also considering interior updates, we offer Bathroom Remodeling in Ontario with the same attention to detail. This isn’t a upsell. It’s bare minimum for a roof that’s going to last 25+ years under this specific climate. Skip the overlay, and you’ll be back in 10 years wondering why your new CertainTeed shingles are failing. When we work on homes near Euclid Avenue or Holt Boulevard, we’re dropping vent calculations and deck inspections into every quote because we know what those 1960s ranches are hiding under the shingles.
We’re not authorized by CertainTeed, and no third-party contractor is. Authorized status doesn’t exist in roofing the way it does in, say, auto repair. What matters is whether the installer follows CertainTeed’s published installation specs and whether they’ll stand behind their own work. We do both. Our Ontario service area covers the full city, from the historic core to the newer subdivisions on the north side.
CertainTeed Models & Products We Service in Ontario
We install and repair four CertainTeed lines that dominate Ontario roofs: Landmark (including Landmark Pro), Presidential, XT25, and NorthGate. Landmark is the workhorse we see most often. Presidential is the premium architectural shingle with the oversized tabs, beautiful on larger Ontario homes but especially vulnerable to wind damage if the adhesive strips fail. XT25 is the budget-friendly three-tab line, and NorthGate is CertainTeed’s SBS-modified shingle designed for impact and flexibility.
Our parts approach is straightforward. We use CertainTeed OEM shingles, underlayments, hip and ridge caps, and starter strips whenever they’re available. For out-of-production lines, like certain older Landmark colorways and the XT25 that CertainTeed has scaled back on, we source aftermarket matches that meet or exceed ASTM standards so the repair blends with the existing roof. We stock common accessories in our Southern California warehouse, which means faster turnaround for Ontario homeowners than waiting on a special order from back east.

FAQs – CertainTeed Construction in Ontario
A properly installed CertainTeed Landmark roof in Ontario typically lasts 20 to 25 years, but west-facing slopes and poor attic ventilation can cut that to 12 to 15. The heat accelerates granule loss and edge cracking, especially on homes without ridge vents or adequate soffit intake. If your Landmark roof is past year 18 and you’re seeing bare patches, call (803) 680-2547 and we’ll tell you honestly whether repair makes sense or if you’re chasing leaks on borrowed time.
We provide a written workmanship warranty covering our installation for 365 days from the completion date. CertainTeed’s material warranty applies to the shingles themselves, and we’ll help you register it. What we can’t do is extend CertainTeed’s warranty because we’re an independent contractor, not a CertainTeed entity. If the work isn’t right within a year, we return at no charge under our 365-Day Done Right Promise. Call (803) 680-2547 for the full warranty terms stated plainly.
Presidential is CertainTeed’s heaviest and most wind-resistant architectural shingle, but only when the adhesive strips seal properly. The installation matters more than the product name. Wind-rated shingles installed with proper nailing patterns and starter strips will hold through Ontario’s gusts. Installed sloppily, even Presidential shingles crease and peel. We’ll talk you through the tradeoffs over the phone at (803) 680-2547.
Yes. Missing shingles after a Santa Ana wind event are one of the most common calls we get in Ontario. The repair usually takes a few hours, and if more than 30% of the roof is compromised, we’ll recommend full replacement rather than patchwork that invites recurring leaks. Call (803) 680-2547 as soon as you notice bare spots, because exposed underlayment fails quickly in Ontario’s sun.
A CertainTeed roof replacement in Ontario typically runs between $8,000 and $20,000, depending on roof size, pitch, tear-off layers, and deck condition. Homes in the historic downtown corridor with skip sheathing often land on the higher end because they need a plywood deck overlay. Call (803) 680-2547 for a free estimate with written line-item pricing.
