CertainTeed Construction in Ontario, CA | Square Deal Contractors

We provide independent CertainTeed roof installation, repair, and exterior system service across Ontario, CA. We’re not affiliated with or authorized by the manufacturer. What makes our CertainTeed work different in Ontario is that we know exactly how this city’s split building stock behaves, from the mid-century tract homes near Euclid Avenue to the newer construction spreading through 91761. If you need CertainTeed work done in Ontario, call (866) 623-7205 and we’ll tell you what you’re dealing with before the first nail goes in.

Why Ontario Residents Choose Us for CertainTeed Service

Ontario isn’t one kind of construction market. It’s two, and they pull in opposite directions. The older core runs on 1950s and 1960s tract homes with original stucco, outdated nailing patterns, and rooflines that were never designed for today’s wind loads. The 91761 corridor runs on warehouse tilt-ups and tenant improvements that get cycled fast and hard. A CertainTeed roof installed on a 1962 ranch near downtown Ontario faces different stress than one on a new infill build near the 91764 edge.

Nolan Breckett grew up in the Baker Ranch area of Lake Forest and learned the trade through the construction technology program at Saddleback College. He’s spent decades watching South Orange County and the Inland Empire build themselves up, and he’ll tell you that the biggest mistakes he sees aren’t material failures. They’re installation decisions made without accounting for local conditions. That’s why our crew stays current with CertainTeed’s installation best practices and product updates. We also carry genuine CertainTeed accessories like ridge vents, starter strips, and fasteners, so your warranty stays intact. But we stock quality aftermarket underlayments and flashings too, because sometimes the right fix for an Ontario roof is a better flashing detail, not a more expensive shingle. Our full CertainTeed sales & service capability means we handle the roofing, the trim, the siding, and the gutters under one contract. That’s the Square Deal way: one contractor, every phase.

Common CertainTeed Construction Problems We Solve in Ontario

Here’s what we see repeatedly on CertainTeed systems across Ontario’s ZIP codes, including 91764, 91798, 91758, and 91761:

• Landmark shingle blow-offs and ridge cap creasing during Santa Ana wind events. Ontario sits in a wind corridor that funnels Santa Ana gusts through the Inland Empire. Older roofs, especially those with 4-nail or hand-nail patterns from the 1960s and 70s, lose shingles along ridge lines and rake edges. We re-secure with proper nailing patterns and genuine CertainTeed sealant strips.
• Cedar Impressions siding warping and loosening from inland heat. South- and west-facing walls in the 91762 and 91764 tracts take brutal UV exposure through Ontario’s hot, dry summers. Vinyl siding expands and contracts, and if it was installed too tight or without proper nailing slots, panels warp or pop loose. We re-nail with correct fasteners and allow for thermal movement.
• Premature granule loss and surface cracking from thermal cycling. Ontario’s summer days run hot, and winter nights can dip cold. That daily expansion and contraction cycle stresses shingle surfaces. We see 15 to 20 year old CertainTeed roofs near downtown with significant granule loss and surface fissuring, especially on unshaded south slopes.
• Restoration Millwork trim rot at butt joints and near grade. In Ontario, sprinkler overspray and poor drainage trap moisture against trim pieces. Composite trim handles this better than wood, but butt joints still wick water if not properly sealed. We replace damaged sections and correct the drainage or spray pattern so the problem doesn’t return.
• Drainage and grading failures that undermine exterior systems. Ontario’s occasional winter rain falls hard and fast. Flat Inland Empire sites don’t shed water quickly, and we see gutter and downspout deficiencies on both residential and light commercial CertainTeed projects that let water pool at foundations or splash back onto siding and trim.

CertainTeed Service in Ontario: What Local Conditions Mean for Your Equipment

Ontario’s historic Euclid Avenue corridor has a construction signature you won’t find in newer Inland Empire neighborhoods. Many of the 1920s through 1950s homes there still have original skip sheathing, which is the spaced board decking beneath the shingles. Some still carry knob-and-tube wiring running through the attic. When we do a CertainTeed roof replacement on one of these homes, the job isn’t just a tear-off and re-shingle. Skip sheathing often can’t support modern shingle fastening requirements, and code now calls for solid decking. Knob-and-tube wiring means electrical coordination before we close the attic back up. This is the kind of thing a generic CertainTeed roofer who mostly works new subdivisions might not catch until the job is open. We catch it during the estimate. Nolan’s phrase for it is simple: “Know what you’re getting into before the first nail goes in.” In Ontario, that means knowing the difference between a 1950s Euclid Avenue roof deck and a 2015 infill build in 91761.

CertainTeed Models & Products We Service in Ontario

We install and repair CertainTeed Landmark® shingles, CertainTeed Presidential Shake™, CertainTeed Cedar Impressions® siding, and CertainTeed Restoration Millwork® trim. When damage is localized, say a few blown shingles or a section of trim rot, we repair it. When shingles are brittle from Ontario’s thermal cycling or granule loss is widespread, we’re straight with you: a full replacement is the better long-term call. Our parts approach is built around warranty compliance where it matters most, using genuine CertainTeed ridge vents, starter strips, and fasteners. For underlayments and flashings, we stock quality aftermarket products that meet or exceed code, which keeps repair costs down without cutting corners on performance. Local Ontario turnaround is faster because we keep common CertainTeed accessories and flashing materials on hand.

FAQs – CertainTeed Construction in Ontario

My CertainTeed Landmark shingles are losing granules after 15 years – do I need a full roof replacement in Ontario’s climate?

Granule loss at 15 years on Landmark shingles in Ontario usually means thermal cycling has done its work. Hot, dry summers bake the asphalt, and the surface becomes brittle. If granule loss is scattered and shingles still flex without cracking, you may get a few more years with spot repairs. If granule loss is heavy across the roof and shingles crack when lifted, replacement is the honest recommendation. Call (866) 623-7205 and we’ll inspect your roof in person before you spend a dollar.

Can you install CertainTeed Cedar Impressions siding on my 1960s Ontario home without removing the original stucco?

Yes. In most cases we install Cedar Impressions siding over existing stucco using furring strips or a drainage plane, provided the stucco is structurally sound and not trapping moisture. Ontario’s dry climate works in your favor here, but we check for hidden moisture at the base of walls before we commit. The big variable is south- and west-facing walls, which see the most UV. We account for thermal expansion in the fastener schedule.

How does Ontario’s occasional winter rain affect CertainTeed roof repairs?

It compresses the window. Ontario gets most of its rain in a handful of winter storms, and when it rains, it rains hard. We prioritize roof repairs ahead of storms and schedule replacements with a weather eye on the forecast. For flat Inland Empire sites, drainage matters as much as the shingles themselves. We check gutters and downspouts as part of every roof repair, because a good CertainTeed roof over a clogged gutter still leaks at the foundation.

Are CertainTeed Restoration Millwork trim pieces suitable for Ontario’s hot, dry climate?

Yes, with one caveat. Restoration Millwork trim is designed to handle UV and thermal stress better than wood, which matters on Ontario’s unshaded south walls. The weak points are butt joints and any place sprinkler overspray hits the trim. We seal joints properly and adjust irrigation heads or drainage so moisture doesn’t sit against the trim. Do that and the product performs well here.

Do you offer emergency roof repair for CertainTeed roofs damaged by Santa Ana winds in Ontario?

Yes, we offer emergency roof repair for CertainTeed roofs damaged by Santa Ana winds in Ontario. We know the wind corridors through 91761 and the older neighborhoods near downtown, and we get calls every wind season for blow-offs and lifted shingles. If your CertainTeed roof is leaking or exposed after a wind event, call (866) 623-7205. We’ll get you tarped and repaired fast, with a straight answer about whether you need a repair or a replacement.
