Free roof inspection with deck photos before we talk money - GAF and Owens Corning certified installation
CertainTeed Roofing in Ontario, CA | Birchbark Roofing
We provide independent CertainTeed in Rancho Cucamonga and across Ontario, CA - repair, replacement, and the underlayment work that this city’s 1980s and 1990s tract homes increasingly need. The single factor that makes CertainTeed work different here is heat: 100-110°F summers bake roofing membranes from above while the deck radiates from below, and nowhere does that show up faster than in the underlayment beneath intact-looking tile. Call (424) 766-4937 for a free estimate on any CertainTeed roof in Ontario.
We know CertainTeed’s product lines well - Landmark, Presidential Shake, Flintlastic, and the tile underlayment systems spec’d across the Inland Empire. We’re also a local Ontario service area crew that understands what 30 years of thermal cycling does to the materials builders installed here. And we’re part of the Cedarwell family of roofing companies, which has held every job to the same care standards since 2000. Our CertainTeed work comes with a written price before anything starts, shoe covers and drop cloths on every visit, and a photo of the cleaned-up site before the crew leaves.
Why Ontario Residents Choose Us for CertainTeed Service
CertainTeed isn’t one product - it’s a family of systems, and each one fails differently in Ontario’s specific conditions. We’ve spent the better part of two decades tearing off and rebuilding these roofs across the region, from mid-century ranch homes to Spanish-tile jobs, and that experience matters when you’re deciding between a patch and a proper fix.
Our owner, Erik Lindgren, learned the fundamentals through the building-construction program at Los Angeles Trade-Technical College and spent years doing roofing work on everything from Northridge ranch homes to Silver Lake tile before starting Birchbark. He’s the person neighbors call when a repair quote from someone else didn’t add up, and he’ll walk you through the estimate line by line until it does. That’s how we approach every CertainTeed job in Ontario - with the material named, the step explained, and no padding. Tell me what you’re seeing, and I’ll tell you exactly what it means for your roof.
We’re independent. That matters because we’re not tied to a manufacturer’s upsell - if a CertainTeed product is the right call, we’ll say so. If a compatible replacement makes better sense for your budget and your roof’s remaining life, we’ll say that too. The decision is yours, and it starts with a written price in dollars before any work begins.
Common CertainTeed Roofing Problems We Solve in Ontario
- Thermal cracking and granule loss on Landmark and Presidential shingles. South- and west-facing slopes in Ontario take the worst of the Inland Empire sun. Shingles rated for 25-40 years here often show cracking and bald patches years ahead of schedule because the mat cooks from both sides. We repair individual damaged areas where the rest of the roof is sound, and we’ll tell you plainly when replacement is the only honest fix.
- Failed underlayment beneath intact tile on 1980s-1990s tract homes. This is the defining Ontario roofing problem. Off Vineyard Avenue, in Creekside, Colony Park - the story is the same. The concrete or clay tile looks fine from the street. The #15 felt underneath has turned to powder. Water gets through, and the first sign is a stain on a master bedroom ceiling. The tile isn’t the problem; the membrane beneath it is.
- Wind damage from periodic Santa Ana events. Santa Ana winds peel loose or under-fastened CertainTeed tile and lift shingle edges and ridge caps, especially along gable ends and hip ridges facing the wind corridor. We see this most often on homes where the original installer skimped on fasteners - a problem that shows up years later in a single windy afternoon.
- Deck and flashing failures on pre-WWII bungalows. Near Euclid Avenue and 4th Street, Ontario’s older housing stock occasionally has CertainTeed shingles installed over aged wood shake or multiple layers of existing composition. The shingles themselves look fine. What’s underneath - the deck, the flashings, the ventilation - is usually the actual failure point. We fix the roof as a system, not just the surface you can see.
- UV-degraded low-slope membranes on patio covers and additions. CertainTeed Flintlastic and RoofRunner membranes on flat sections age from sun exposure long before they age from rain. Ontario gets about 15 inches of rain a year, and most of it arrives in a handful of winter storms. A membrane that’s been baking all summer often shows ponding, open seams, or blisters the first time a concentrated downpour hits. We find this on patio covers and room additions all over Ontario.
CertainTeed Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s 1980s-1990s tract-home boom left thousands of tile roofs whose visible surfaces still pass inspection while the underlayment underneath has already powdered out. That’s the information gain here - something true of Ontario in a way it isn’t of younger or coastal markets. In the Creekside neighborhood off Vineyard Avenue, we tore off a 1990s concrete tile roof on a stucco tract home where the homeowner had chased a recurring water stain on the master bedroom ceiling for two seasons. Every tile was intact. The CertainTeed-era underlayment underneath had disintegrated into fine powder. We pulled the tile, replaced the failed membrane with a modern CertainTeed-compatible high-temp underlayment, re-laid the original tile, and the leak stopped where three prior patch attempts had not.
What this means for you, specifically: if your Ontario home’s tile roof is over about 30 years old, age the underlayment, not the tile. The tile may have decades left. The felt beneath it likely doesn’t. CertainTeed’s own modern underlayment products - WinterGuard, Roofers’ Select, SwiftStart starter - are built for higher heat than the #15 felt of the 1980s and 1990s was ever designed to withstand. That’s the upgrade that changes the trajectory of these roofs.
CertainTeed Models & Products We Service in Ontario
We work on the full CertainTeed roofing portfolio. On the shingle side, that means Landmark, Landmark Pro, and Landmark IR architectural shingles, plus Presidential Shake and Presidential Solaris luxury profiles. On low-slope and flat sections, we service Flintlastic SA, Flintlastic GTA, and RoofRunner membranes, including the transitions where flat sections meet tile or shingle slopes. We also handle CertainTeed tile underlayments and accessories - WinterGuard, Roofers’ Select, and SwiftStart - which are exactly the components that matter most on Ontario’s aging tract homes.
Our approach on parts: we use genuine CertainTeed accessories - starter, ridge, hip, and ventilation components - wherever they affect system performance or membrane continuity. Mixing brands on a CertainTeed roof undermines the design intent, so we don’t do it. When a CertainTeed product is discontinued or matching pieces are unavailable, we’ll tell you straight and pivot to a compatible quality replacement rather than installing a patch that won’t survive the next heat cycle. That honesty is part of how we CertainTeed sales & service differently than a parts-counter shop would.
CertainTeed Service Pricing in Ontario
Most CertainTeed repairs we quote in Ontario land between $450 and $1,800, depending on scope. Targeted shingle replacement on a single slope runs $450-$900. CertainTeed tile underlayment replacement - the big one for Ontario’s 1990s tract homes - typically falls between $9 and $15 per square foot, including tear-off, new underlayment, tile re-lay, fasteners, flashing work, and disposal. Full CertainTeed Landmark replacement on an average Ontario home usually runs $11,000-$19,000 depending on roof size, deck condition, and the model line you choose. Presidential Shake runs higher because the material cost is higher.
Every estimate includes the exact dollar number in writing before work starts. You’ll see the material line items, labor, disposal, and any permit fees itemized separately. Estimates are free, and there’s no obligation. Call (424) 766-4937 to schedule yours.

FAQs - CertainTeed Roofing in Ontario
Yes, and this is the single most important question to ask about any tile roof in Ontario over about 30 years old. The tile itself will survive the Inland Empire heat for decades. The original #15 felt underneath almost certainly will not - it bakes to powder from decades of 105°F thermal cycling, and the first sign is a water stain on a ceiling, not visible tile damage. We recommend an underlayment evaluation on any pre-2000 tile roof in Ontario. Call (424) 766-4937 and we’ll schedule an inspection.
Often yes, if the underlying deck and most of the shingles are sound, and Ontario Roof Repair is the right approach. We replace cracked, blistered, or granule-lost shingles on affected slopes - usually south- and west-facing slopes in Ontario - and match the color and profile as closely as the remaining stock allows. If the shingles are failing across multiple slopes or the deck is compromised, we’ll tell you that a repair would be throwing good money after bad, and we’ll show you the numbers both ways. Estimates are free.
Intense UV and thermal expansion degrade these membranes even without rain. CertainTeed Flintlastic and RoofRunner membranes on Ontario patio covers typically fail from sun exposure first - you’ll see blisters, open seams, or ponding after the first winter storm following a long dry spell. We inspect low-slope sections for UV fatigue before they leak, and we repair or replace membranes with materials rated for sustained high-heat exposure. Call (424) 766-4937 to schedule a look.
No. We work with materials from GAF, Owens Corning, IKO, Atlas, Tamko, and Boral as well, and we’ll recommend whichever system fits your roof’s condition, your budget, and the demands of Ontario’s climate. We don’t push CertainTeed where it isn’t the right call, and we don’t push replacement where a repair is the honest answer.
No, and we say that plainly. Birchbark Roofing is an independent CertainTeed service provider - not authorized, sponsored, or warranty-endorsed by the manufacturer. That independence means we make recommendations based on what your Ontario roof actually needs, not on what a manufacturer program requires us to sell. It also means we can be honest when a compatible replacement makes more sense than forcing a discontinued CertainTeed product onto your roof.
