CertainTeed Roofing in Ontario, CA | Huntington Beach Roofers
We provide independent CertainTeed roofing service across Ontario, from tear-offs on 1950s ranch homes in the older core to low-slope membrane work on the 91761 warehouse belt. The thing that makes our CertainTeed work here different is simple: we install and repair these products in a city where the same week can put us on a four-layer composition tear-off downtown and a Flintlastic seam repair along a logistics corridor parapet. That dual-market reality shapes how we spec, detail, and warranty every CertainTeed job we run in Ontario. Call (833) 467-4901 for a straight assessment and a free estimate.
Why Ontario Residents Choose Us for CertainTeed Service
CertainTeed makes a broad product line, but the difference between a roof that lasts and one that fails early usually comes down to installation details and honest material recommendations. We’ve spent years putting CertainTeed Landmark architectural shingles, XT25 three-tabs, and Flintlastic membranes on Ontario roofs, and we’ve also spent years repairing the ones that weren’t detailed right in the first place. Neil Stratton is the owner here at Huntington Beach Roofers, and his approach is direct: “Tell me what the roof is doing, and I’ll tell you what it actually needs.” If the field shingles are still sound, we’ll say so and recommend a targeted repair with genuine CertainTeed accessories. If the deck is shot or you’re sitting on three layers of nailed-over shingles, we’ll tell you a tear-off is the only honest move. We stock CertainTeed starter strips, ridge caps, and matching shingle colors locally for faster turnaround on Ontario jobs. We’re the contractor that handles inspection, repair, and replacement under one roof, so you’re not bouncing between a sales rep and a sub crew when something needs to get done. Check our CertainTeed sales & service page for the full scope of what we carry.

Common CertainTeed Roofing Problems We Solve in Ontario
- Sun-cured shingle tabs that curl and crack. Ontario’s summer sun is relentless, and south- and west-facing CertainTeed Landmark and XT25 slopes take the worst of it. Seals fail first, then tabs curl, then the wind gets under them.
- Santa Ana wind lift on aging ridge caps. During wind season, older CertainTeed ridge caps on the 1950s and 60s ranch homes in ZIPs 91762 and 91764 lift and tear off fast. One gusty afternoon can strip a cap run that’s been weakening for years.
- Three and four layers of old composition shingles. Downtown and south Ontario ranch homes often carry multiple nailed-over layers on a roof that started as a 1950s CertainTeed or comparable install. That means a full tear-off, and frequently decking replacement once we get down to the sheathing.
- Flintlastic seam failure on flat warehouse roofs. The 91761 corridor’s flat CertainTeed Flintlastic and modified-bitumen membranes expand and contract with daily thermal cycling. Seams and parapet flashing open up long before the membrane itself wears through.
- Flashing leaks that show up when rain finally comes. Ontario gets little rain, but when it does, it’s often intense. Neglected flashing around chimneys, skylights, and pipe boots is where we find most residential leaks, especially on older CertainTeed roofs.
CertainTeed Service in Ontario: What Local Conditions Mean for Your Roof
Ontario is one of the few SoCal cities where the same roofing market runs from 1950s and 60s ranch re-roofs with three or four shingle layers to flat TPO and modified-bitumen membranes on the sprawling 91761 warehouse belt. That split isn’t something you find in Pasadena or Sierra Madre. It means a CertainTeed crew here has to be fluent in steep-slope tear-offs and low-slope membrane work in the same week, sometimes the same day. In the older 1950s ranch blocks near downtown Ontario, we stripped a CertainTeed XT25 roof that had four layers of old composition shingles nailed over dried skip sheathing, replaced the split decking, re-sheathed, and installed CertainTeed Landmark architectural shingles with new ridge caps. Down in the 91761 logistics corridor, our crew resealed a failing CertainTeed Flintlastic membrane where thermal cycling had opened the seams along a warehouse parapet. Two very different CertainTeed jobs on the same schedule. Most contractors in this market lean one direction or the other. We work both, and that’s a practical advantage when your roof doesn’t fit a single category. If you’re in Ontario service area and want a contractor who understands both sides of the city’s roofing stock, we’re the crew to call.
CertainTeed Models & Products We Service in Ontario
We install and repair the full CertainTeed lineup most common in Ontario: Landmark architectural shingles, Presidential Shake and Presidential TL for higher-profile premium looks, XT25 three-tabs for budget-conscious reroofs and patch work, and Flintlastic modified-bitumen membranes for low-slope and flat applications. We use genuine CertainTeed accessories, starter strips, ridge caps, and matching shingles, so color and profile tie in correctly. We don’t substitute generic accessories on a CertainTeed roof; the color mismatch and profile gaps cause more callbacks than the savings were ever worth. For fast Ontario turnaround—and quick CertainTeed repair in Chino when needed—we keep common Landmark colors and standard accessory stock on hand or within a day’s delivery from our local supply lines.

AfterCertainTeed Service Pricing in Ontario
CertainTeed roofing work in Ontario runs a wide range because the city’s housing stock spans from small 1950s three-tab ranch roofs to large steep-slope architectural replacements and flat commercial membranes. A targeted repair, like replacing a dozen sun-cured tabs or resealing a section of Flintlastic seam, typically lands between $350 and $900. Full residential tear-offs with Landmark architectural shingles usually fall from $8,500 to $16,000 depending on square footage, decking condition, and how many old layers need to come off. Low-slope Flintlastic work on warehouse and commercial builds runs higher, often $12,000 to $30,000, because membrane material and labor both climb. Every estimate we write is itemized, so you can see exactly what’s driving the number. Call (833) 467-4901 and we’ll walk the roof with you, no charge for the estimate.

FAQs – CertainTeed Roofing in Ontario
No. We’re an independent CertainTeed roofing contractor. That means we’re not tied to a manufacturer’s sales quota or a dealer program’s product push. Our credibility comes from years of installing and repairing CertainTeed products across Ontario’s climate and providing CertainTeed in San Antonio Heights, and from telling homeowners straight when a repair makes sense and when it doesn’t.
We use genuine CertainTeed accessories on every CertainTeed job. Starter strips, ridge caps, and matching shingles all come from CertainTeed so the color and profile tie in correctly. Generic accessories are cheaper up front, but mismatched ridge caps and off-profile starter strips fail faster, and in Ontario’s sun, faster means a lot sooner than the warranty suggests.
That depends on what the roof needs. A small shingle repair or Flintlastic seam reseal is usually a same-day job. A full tear-off with decking replacement on a 1950s Ontario ranch home typically runs three to five working days. If it’s a multi-layer tear-off with dried sheathing replacement, budget closer to a week. Call (833) 467-4901 and we’ll give you a realistic timeline for your specific roof.
We work on Landmark architectural shingles, Presidential Shake and Presidential TL, XT25 three-tabs, and Flintlastic modified-bitumen low-slope membranes. That covers nearly every CertainTeed roof in Ontario, from the steep ranch gables in the older neighborhoods to the flat warehouse decks in the 91761 corridor, and we also handle CertainTeed in Upland.
Most Ontario repairs land between $350 and $900. A simple tab replacement on a south-facing slope or a small flashing reseal sits at the lower end. Seam work on a Flintlastic flat roof or a ridge cap run repair after Santa Ana damage runs higher. For an exact number, call (833) 467-4901, and we’ll send someone out to look at it before any estimate is written.
