CertainTeed Construction in Ontario, CA | Workshop Contractors
We provide independent CertainTeed roofing and siding installation, repair in Chino, and replacement across Ontario, CA. What makes our CertainTeed work different here is that we grew up in this city and know how its post-war slab-on-grade tract homes and 100°F summers actually stress these products. Call (844) 384-3361 to schedule a free estimate on any CertainTeed project, from a single roof repair to a full standing seam replacement.
Why Ontario Residents Choose Us for CertainTeed Service
We’ve spent years putting CertainTeed Landmark shingles, Presidential Shake, and Cedar Impressions siding on homes from the older streets south of Holt Blvd to the newer planned communities on the city’s east side. Our crew reads CertainTeed’s installation manuals like a code book, not a brochure, because we’re independent and accountable only to the homeowner. Noel Figueroa, our owner and general contractor, grew up in the Vineyard neighborhood of Ontario and learned framing at Chaffey College, where the construction technology program put him on job sites before he could legally rent a truck. That local grounding means we don’t guess at how Ontario’s expansive clay or Santa Ana wind patterns will affect your CertainTeed system. We’ve already seen it on hundreds of roofs in this city. And because we’re a full-service general contractor, CertainTeed sales & service sits alongside windows, siding, fencing, and interior work under one contract and one schedule.

Common CertainTeed Construction Problems We Solve in Ontario
- Accelerated granule loss on south- and west-facing Landmark slopes. In Ontario’s semi-arid inland valley, roof surfaces regularly exceed 140°F in July and August. On 1970s tract homes where attic ventilation was undersized from day one, we see thermal cracking and premature granule shedding on young Landmark shingles. We re-roof with upgraded ridge and soffit ventilation, then install new CertainTeed OEM shingles to spec.
- Cedar Impressions siding buckling on pre-1980 stucco homes. South of Holt Blvd, many of Ontario’s mid-century stucco homes have original scratch coats that were never properly prepped for a siding retrofit. Add Santa Ana winds driving rain into unflashed seams, and you get caulk-joint failure and wavy panels. We strip the failed courses, correct the substrate, and reinstall with proper flashing and OEM components.
- Tile underlayment failure on 1990s east-side homes with low-slope porches. Heat buildup plus monsoon-season moisture cycling degrades CertainTeed tile underlayment early on low-slope porch roofs across Ontario’s newer east-side neighborhoods. The tiles look fine; the leak starts underneath. We replace the underlayment before swapping tiles back on.
- Parapet flashing deterioration on commercial tilt-up buildings. Ontario’s wide day-night temperature swings cause thermal movement at parapet transitions on older tilt-up warehouses and masonry buildings. CertainTeed weather-barrier and flashing details fail there first. We rebuild those transitions with movement-tolerant details and OEM flashing.
- Roof-to-wall flashing stress from foundation movement. In older south Ontario, slab-on-grade homes with shallow footings shift on expansive clay. That movement telegraphs up through the wall plate and stresses the roof-to-wall flashing. We see separated eave details that let water into the wall cavity. We fix the flashing and, where needed, the eave structure before reinstalling the CertainTeed system.
CertainTeed Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s older south-side tract homes were built on slab-on-grade with shallow footings over expansive clay, so when we re-roof or re-side, we often find the roof-to-wall flashing has been stressed by foundation movement. This condition rarely shows up in the newer north-side communities with post-tension slabs. It’s not a CertainTeed product defect; it’s a structural reality of how these houses were built in the 1940s through 1970s. On a 1958 ranch near downtown Ontario, our crew tore off three layers of failing Landmark shingles and found the original skip sheathing had separated from the wall plate where the slab had shifted, similar to CertainTeed in San Antonio Heights homes with comparable age. We rebuilt the eave detail with new CertainTeed underlayment and flashing, then installed Landmark shingles with an upgraded ventilation layer to handle the attic heat. The homeowner passed city inspection without a single correction. That’s what local knowledge buys you: a crew that knows why the flashing pulled away in the first place, and fixes the cause, not just the symptom.
CertainTeed Models & Products We Service in Ontario
We install and repair the full CertainTeed roofing and siding line, including Landmark architectural shingles, Presidential Shake, Cedar Impressions siding, and Northwoods fiber cement siding. We use CertainTeed OEM shingles, underlayment, and flashing components because mixing brands voids the system warranty and creates incompatible detail interfaces. Our suppliers in Ontario keep the most common Landmark colors and CertainTeed underlayment rolls in local stock, which means most repairs don’t wait on a freight delivery from out of state. When a repair can honestly extend the life of a sound roof or siding plane, we say so. When granule loss or substrate rot has passed a threshold, we’ll show you why replacement is the better spend. Noel likes to put it simply: build it right the first time. The second time costs twice as much and nobody’s happy about it.

FAQs – CertainTeed Construction in Ontario
Yes. Landmark shingles are rated for the wind speeds Ontario sees during fall Santa Ana events when installed to CertainTeed’s published installation specs, which include proper nail count, nail placement, and starter course detailing. The bigger issue in Ontario is almost always roof deck attachment on older homes, where original nailing patterns were sparser than current code allows. We check the deck fastening before we install anything. Call (844) 384-3361 to have us assess your roof before the next Santa Ana season.
Most cracking CertainTeed siding on 1960s Ontario homes can be repaired panel-by-panel if the substrate behind it is still sound and the cracking is isolated. But if we find the original stucco scratch coat underneath is separating, or water has been getting behind the panels along failed seams, partial repairs become a losing game. We’ll open a test section and show you what’s back there before recommending either direction. Call (844) 384-3361 for an honest assessment.
On many 1990s Ontario homes, the porch roof has a lower slope than the main roof, and the CertainTeed tile underlayment under it degrades from heat buildup long before the tiles themselves fail. The tiles stay intact; the underlayment beneath them doesn’t. We fix this by removing the tiles, replacing the degraded underlayment with current CertainTeed material rated for low-slope applications, and reinstalling the tiles. Call (844) 384-3361 and we’ll take a look before the next rain.
In most cases, yes. Standing seam metal can be installed over a single layer of existing shingles if the deck is sound and the structure can handle the load. Ontario building codes and manufacturer specs dictate what’s allowed. We will tell you if a tear-off is required, typically when there are multiple shingle layers or the deck is compromised. Call (844) 384-3361 for a roof assessment and exact quote.
Expansive clay under your foundation causes seasonal volumetric movement in the foundation, which translates up through the wall plate and stresses the roof-to-wall flashing over time. We see this on older slab-on-grade Ontario homes where shallow footings were the original standard. Before any re-roof, we inspect eave and rafter connections for signs of that movement so we aren’t installing a new CertainTeed system on top of a structural stress point. Call (844) 384-3361 to have your roof assessed by a contractor who understands Ontario soils, not just shingles.
