Why Ontario Residents Choose Us for CertainTeed Service
Nelson Fung started learning materials the way a lot of kids did in Chinatown, Los Angeles: Saturday mornings at Saigon Plaza while his grandfather argued tile prices on Broadway. That obsession with how products actually hold up followed him through Los Angeles Trade-Technical College and years of swinging hammers across the LA basin. Today, our crew brings the same scrutiny to every CertainTeed installation in Ontario.
Roofing and siding in the Inland Empire have to survive conditions that beat up lesser products. We have worked with CertainTeed enough to know exactly which of their product lines make sense for which Ontario streets, and which installations will fail early if someone skips a step. We use genuine CertainTeed OEM parts for repairs and replacements so warranties stay intact, and we will tell you plainly when an aftermarket option is smarter for your budget.

Common CertainTeed Construction Problems We Solve in Ontario
Here are the CertainTeed failures we see most often across Ontario homes, with the local factors that bring them on faster:
- Landmark shingle granule loss and fading on south- and west-facing slopes – Ontario’s intense UV exposure cooks asphalt shingles relentlessly. The south and west planes of a roof can look ten years older than the north slope of the same roof. By years 15 to 20, granule loss is heavy and the shingles have lost flexibility. If you notice granules piling up at gutter downspouts, that shingle surface is shedding its protection.
- Presidential Shake cracking and blistering from poor attic ventilation – Many of Ontario’s 1950s and 1960s tract homes were built with scant attic space and undersized venting. Presidential Shake shingles are thicker and need to shed heat, and when they cannot, they blister and crack. We check venting before we quote any re-roof because installing premium shingles over a suffocating attic just guarantees a callback.
- Cedar Impressions siding warping on stucco-over-plaster walls – Ontario’s older homes expand and contract hard through hot summers and cool winter nights. Cedar Impressions siding installed without proper clearance on stucco-over-plaster will warp or show fastener pull-through within a few seasons. The fix is not just new siding; it is proper standoff and nailing pattern.
- Monogram siding cracking under Santa Ana wind-driven debris – Santa Ana winds can push tree branches, palm fronds, and whatever else is loose into siding at speed. Monogram siding on two-story homes with big surface areas gets brittle after years of sun and then cracks on impact. We carry matching OEM panels for common Ontario colorways to make repairs clean.
- Hidden asbestos-cement CertainTeed materials from mid-century builds – This is the one that surprises homeowners. Many 1940s to 1960s Ontario homes have original CertainTeed asbestos-cement siding or roofing panels buried under newer layers. You cannot just rip into them. Testing and proper disposal are required before any re-roof or re-side project starts, and skipping that step is both dangerous and illegal. More on this below.
CertainTeed Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario sits at the junction of the 10, 60, and 15 freeways, which made it a warehousing and logistics build-out hub decades before it became one of the Inland Empire’s most active residential remodeling markets. That dual identity means construction here runs across two very different build types in the same ZIP codes: industrial tilt-up and concrete work near the rail and airport zones, and mid-century tract home remodels everywhere else. For CertainTeed owners, this has a specific consequence. Many roofing and siding crews in Ontario split their time between commercial tenant improvements and residential work, and they carry habits from one into the other. Residential CertainTeed installations need different fastening patterns, different flashing details, and more patience than a tilt-up wall. When we quote CertainTeed work in neighborhoods like the ones around Euclid Avenue or Holt Boulevard, we are quoting it for the house in front of us, not for the warehouse project we just left. Our full Ontario service area is detailed here.
CertainTeed Models & Products We Service in Ontario
We install and repair the CertainTeed product lines you are most likely to find on Ontario homes:
- CertainTeed Landmark asphalt shingles – the workhorse of Ontario roofing. We stock common colors and matching ridge caps for fast repairs.
- CertainTeed Presidential Shake – the luxury laminate. We handle full replacements and selective repair where decking and venting are sound.
- CertainTeed Cedar Impressions siding – the polymer shake and shingle line that looks like cedar and behaves like a siding product designed for weather extremes.
- CertainTeed Monogram siding – horizontal lap siding we see frequently on 1990s and early 2000s Ontario homes.
We also handle CertainTeed metal roofing for Montclair homeowners who want to stop thinking about their roof for several decades. For repairs, we use OEM CertainTeed parts to keep warranty coverage alive, and we will show you the aftermarket option when it genuinely saves money without cutting corners.

AfterCertainTeed Service Pricing in Ontario
| Service | Price Range |
|---|---|
| Roof Repair | $400 – $1,800 |
| Roof Replacement | $8,000 – $20,000 |
| Metal Roof Installation | $15,000 – $40,000 |
What drives the spread? Roof size, pitch, the condition of the decking underneath, and whether asbestos-cement materials need testing and abatement all move the number. Ontario’s older tracts often need decking replacement once we get the old shingles off, and that is not something a phone quote can see. A free estimate from us includes an on-site look and a written line-item quote, so the number you sign is the number you pay. Call (866) 253-5808 to schedule one.

FAQs – CertainTeed Construction in Ontario
We do not recommend it. Layering hides decking rot, adds weight your framing may not be sized for, and traps Ontario’s summer heat, which shortens the life of both layers. Some Ontario lots have original roof framing that was never designed for a second course. A full tear-off lets us inspect decking and venting and gives you a roof that lasts 25 to 30 years instead of a double layer that will need attention inside of 15. Call (866) 253-5808 and we will tell you what your specific roof needs.
Cedar Impressions is formulated to hold color against UV, and it holds up better than wood or vinyl in Ontario’s heat, so we often recommend it for CertainTeed repair in Chino as well. The failure mode we see is not the product breaking down; it is installer error on stucco-over-plaster walls. Without proper clearance and fastening, panels warp or pull through. Installed correctly, it will give you decades. Our crew has the installation reps on file for Ontario conditions.
In Ontario’s specific climate, a properly installed CertainTeed Landmark roof typically lasts 22 to 28 years. The UV and heat will take a few years off the manufacturer’s maximum, and attic ventilation matters more here than in coastal cities. If your attic is not breathing, even premium shingles will blister early. We will check venting before we quote any replacement.
Yes. We pull permits in the City of Ontario for roof replacements and coordinate inspections, and we offer the same thorough service for CertainTeed in San Antonio Heights. Ontario’s building department has specific reroofing requirements, and we handle the paperwork end to end. You will not be left calling a city planner to find out what we should have filed.
Yes, but only with proper furring strips, moisture management, and fastening that accounts for how those mid-century plaster walls expand and contract. Installing directly over stucco without a rainscreen detail is how we end up redoing someone else’s work. Call (866) 253-5808 for an exact quote on your Ontario home; our estimates are free.
