CertainTeed Roofing in Ontario, CA | Bedrock Roof Repair
We provide independent CertainTeed roofing service across Ontario, from shingle and tile work in the older tracts to flat-roof repairs on the warehouse belt. We’re not a CertainTeed authorized dealer or manufacturer affiliate, and we don’t pretend to be. What sets our CertainTeed work apart in Ontario is that we read the roof the way the city actually builds and weathers it: post-war hip roofs in 91762 fail differently than Flintlastic membranes along the 10/60 corridor, and we plan for both. Call (833) 589-7850 for a free estimate on any CertainTeed roof issue.
Why Ontario Residents Choose Us for CertainTeed Service
CertainTeed makes a deep product line, and you need a contractor who can tell a Landmark failure from a Presidential Shake problem without standing on a ladder guessing. Alan Cofield, who owns Bedrock Roof Repair, trained in the building trades at Cypress College and has spent the better part of two decades on Southern California roofs. He grew up in the Anaheim Colony neighborhood watching older houses lose their battle with deferred maintenance one cracked tile at a time, which is why our whole approach starts with diagnosis before demolition. In Ontario, that means knowing that a 1960s comp shingle roof in 91761 and a TPO flat roof off the 10 freeway are two completely different animals, even when both have the CertainTeed label on them. We also work with all seven major roofing material brands, including GAF, Owens Corning, IKO, Atlas, Tamko, and Boral, so our recommendation follows your roof’s condition and your budget, not a supplier incentive. See our full CertainTeed sales & service page for more on how we handle the product line.

Common CertainTeed Roofing Problems We Solve in Ontario
- Santa Ana wind uplift on Landmark shingles. In Ontario’s older tracts, particularly 91762 and 91761 near downtown, the seasonal Santa Anas hit hip roofs hard. On CertainTeed Landmark Architectural Shingles, we routinely see seal-strip failure after these events: the wind gets under the shingle edge, breaks the adhesive bond, and you lose shingles in patches rather than one at a time. If the underlayment underneath is original to a 1960s roof, the problem compounds quickly.
- Baked and crumbling tile underlayment on 1950s-60s homes. Inland Empire summers regularly exceed 100°F, and that heat does not just age the tile you can see. It bakes the CertainTeed felt underlayment underneath until it crumbles. We’ve been on plenty of Ontario roofs where the concrete tile looks fine from the ground, but the underlayment has turned to powder, and water is getting through every seam.
- Ponding water and UV degradation on Flintlastic flat roofs. The warehouse and distribution buildings along the 10 and 60 corridors in 91764 and 91761 are a different CertainTeed market entirely. Flintlastic SA Cap Sheet roofs out there take relentless sun exposure and, when drainage clogs or the membrane sags, ponding water accelerates seam failures and blistering. We patch these regularly for property owners who need the roof back in service without a full re-roof.
- Discontinued concrete tile matching after windstorms. A Santa Ana event in Ontario’s 91762 tract often loosens or breaks clay tiles that were installed in the Eisenhower administration. The manufacturer stopped making that tile decades ago. If you call a contractor who does not do salvage work, they’ll tell you the whole roof needs to come off. We go looking for the tile first.
- Carriage House and Presidential Shake cosmetic and wind damage. These are premium CertainTeed lines, often chosen for curb appeal on the newer two-story subdivisions on Ontario’s south and east sides. They hold up well, but when they do fail, it’s usually wind-related lifting at the edges or impact damage. We replace individual shingles and retrain the surrounding courses rather than reskinning the whole slope.
CertainTeed Service in Ontario: What Local Conditions Mean for Your Roof
Ontario’s roofing market splits along the Santa Ana River wind corridor and the 10/60 freeway divide, and that split changes how CertainTeed products get serviced here. In the older post-war tracts around downtown and the Edison Historic District in 91762, you’re dealing with 1950s-60s single-story stucco homes wearing concrete clay tile or comp shingle. Those roofs are hip-roofed, which means wind has more edge to work with, and the underlayment is almost always past its useful life. Meanwhile, a few miles away in 91764 and the logistics belt, you have hundreds of acres of low-slope warehouse roofs, mostly CertainTeed Flintlastic or TPO systems, where the fight is against ponding water and UV cooking under triple-digit summer heat. A roofer offering CertainTeed repair in Chino or Rancho Cucamonga might see one side of that equation. We work both within a few miles of each other, which means when a property owner calls us, we already know whether we’re looking at a tile underlayment problem or a flat-roof seam failure before we get up the ladder. Alan puts it this way: “The roof tells you what went wrong. You just have to know how to read it.”
CertainTeed Models & Products We Service in Ontario
We work on the full CertainTeed residential and commercial line you’re likely to find in Ontario, with CertainTeed service in Montclair and nearby areas as well. That includes Landmark Architectural Shingles, Presidential Shake, and Carriage House Shingles on the residential side, plus Flintlastic SA Cap Sheet and low-slope membrane systems throughout the warehouse belt. For warranted installations, we use genuine CertainTeed accessories and underlayments so the manufacturer’s terms stay intact. For repairs, we source quality aftermarket components that meet or exceed OEM spec, and we’re clear with you about which is which. We keep common match stock for the discontinued tile profiles we see most often in 91762, and we can usually source anything else from salvage yards along Holt Blvd within a day or two.

AfterCertainTeed Service Pricing in Ontario
Repair pricing in Ontario depends on what’s actually failing, not on the brand name on the shingle. A straightforward shingle replacement or flat-roof patch runs on the low end and gets done in one visit. Tile underlayment replacement costs more because it’s labor-intensive: every tile has to come up without breaking, the old felt gets stripped, new CertainTeed underlayment goes down, and the original tiles get reset. A full tear-off and replacement is the most expensive option, and we only recommend it when the decking or underlayment has failed so badly that patching would be throwing good money away. Your free estimate includes a written line-item quote so you can see exactly what each part costs. Call (833) 589-7850 and we’ll get you numbers you can actually plan around.

FAQs – CertainTeed Roofing in Ontario
Ontario’s inland summer heat, which regularly tops 100°F, dries out asphalt shingles and tile underlayment far faster than the milder coastal climate does, which means CertainTeed Landmark shingles here lose their adhesive bond and flexibility earlier in their lifespan, and the underlayment beneath tile roofs often crumbles before the tile itself shows damage. You’ll see more seal-strip failure and more hidden underlayment leaks in Ontario than you would in a coastal city like Long Beach, even on roofs installed the same year. If your roof is more than 15 years old, an inspection is cheaper than finding out after the first winter rain. Call (833) 589-7850 for a free estimate.
Yes, and we do it regularly. After a Santa Ana wind event, homes in Ontario’s 91762 tract often lose concrete clay tiles that have been out of production for decades. We salvage matching tiles from builder-left spares found under the original underlayment and from salvage yards along Holt Blvd, then reset them with new CertainTeed underlayment and proper fasteners so the repair holds through the next wind season. This is a service you won’t get from a contractor whose only answer is a full replacement. Call (833) 589-7850 and tell us what your tile profile looks like.
Ponding water and UV degradation are the two biggest causes of flat roof leaks on Ontario’s warehouse belt. On CertainTeed Flintlastic systems, water that doesn’t drain sits on the membrane, and combined with the Inland Empire’s intense sun, the seams separate and the membrane blisters until water finds a way through. It’s usually repairable as a targeted patch if you catch it before the insulation underneath gets saturated. Call (833) 589-7850 for an inspection if you’re seeing water stains on the ceiling or walls.
We lift each tile carefully, in labeled sections, and stack them on the roof where they came from. The old CertainTeed felt gets stripped, the decking gets inspected, and new underlayment goes down before the original tiles go back in order. We replace any that crack during the lift with salvage-matched tile from our Holt Blvd sources or builder spares. The goal is to keep the original roof character intact while giving it another 20 to 30 years of water protection. Call (833) 589-7850 to schedule an inspection before the next rain season.
We use genuine CertainTeed accessories and underlayments when a warranted installation is on the line. For repairs, we source quality aftermarket components that meet or exceed OEM specifications, and we tell you which is going on your roof before the work starts. You get the right material for the job, not whatever a supplier pushed that month. Call (833) 589-7850 to talk through what your roof actually needs.
