CertainTeed Construction in Ontario, CA | San Mateo Construction
We provide independent CertainTeed service across Ontario, from re-roofs on postwar stucco ranchers in 91762 to wind-damage repairs on newer homes near 91761, and we also offer CertainTeed service in Montclair. The thing that sets our CertainTeed work apart here is that we know Ontario’s roof failures split by ZIP: older slab-foundation tracts need deck and flashing work before shingles go down, while newer infill fails first at Santa Ana-exposed edges and valleys. Call (855) 901-7266 for a free estimate.
We’re not a manufacturer affiliate or an authorized CertainTeed dealer. We’re a licensed general contractor that installs and services CertainTeed roofing and exterior systems because the product line holds up well in this climate when it’s detailed correctly. And “detailed correctly” is where Ontario gets interesting. The same Landmark shingle installs differently on a 1950s Euclid Avenue ranch than it does on a 2015 subdivision home off the 15. We’ve done both, many times over. Noel Carrington, Owner at San Mateo Construction, grew up learning the trade from his father pouring concrete footings in San Mateo County; he’s been running multi-system residential and commercial jobs for nearly three decades now. That means when we quote a CertainTeed roof in Ontario—or CertainTeed in Upland nearby—we’re quoting it against the actual conditions your specific block throws at it.
Why Ontario Residents Choose Us for CertainTeed Service
CertainTeed matters in Ontario because the sun here doesn’t just fade roofs, it bakes them. The high-desert UV load, the summer heat that sits on an asphalt shingle for months, the Santa Anas that hit exposed eave edges like a pressure test, all of it means product choice and installation detail decide whether a roof lasts 15 years or 30. We know the CertainTeed lines well: Landmark architectural shingles for most homes, Presidential Solaris when cool-roof performance matters on a west-facing plane, WinterGuard underlayment at valleys and eaves where the wind drives water uphill. We also know when a product is wrong for a job. We won’t put a shingle on a deck that’s moving underneath it and call it done.
Being local to Ontario means we carry the accessory components that make CertainTeed systems perform; matching hip-and-ridge, Ridge Vent, WinterGuard in the widths these roof planes actually need. We stock what’s common for this market, so we’re not waiting on a distributor run to San Bernardino every time a valley flashing fails after a wind event. And because we run one crew across roofing, windows, siding, and interior work – not a rotating cast of subcontractors nobody’s fully accountable for – the guy who answers your question about deck sheathing is the same contractor who signs the permit package.

Common CertainTeed Construction Problems We Solve in Ontario
- Accelerated granule loss on west- and south-facing Landmark shingles. Ontario’s summer sun oxidizes asphalt fast. On unshaded roof planes, Landmark shingles can show surface cracking and granule loss years before a shaded slope of the same age. We assess whether it’s cosmetic or structural before recommending repair or replacement.
- Santa Ana wind uplift at eaves and rakes. High gusts peel shingles where field nails were placed too high on the common bond. We see this most on east-edge homes near the 91761 subdivisions, where wind corridors run unobstructed. Fixing it means a wind-rated nailing pattern, not just pressing the shingle back down.
- Failed valley and penetration flashings. Heat cycling at valleys, especially where a low-slope patio cover meets a steeper shingle plane, opens sealant joints faster than the shingle itself ages. UV turns the sealant brittle, water gets in, and the deck rots. This is one of the most common CertainTeed service calls we get in Ontario.
- Original 1950s roof decks telegraphing through new shingles. In 91762 and 91764, skipped sheathing and aging felt on postwar tract homes mean a new CertainTeed shingle layer shows deck movement and flashing failures that aren’t the shingle’s fault. The roof looks new; the structure underneath it isn’t.
- Incorrect underlayment on low-slope sections. Ontario’s hot, dry climate makes some contractors skip WinterGuard where it’s actually needed, at valleys and eaves where Santa Ana-driven rain runs sideways. A dried-out felt underlayment under a new Landmark field is a failure waiting for the next winter storm.
CertainTeed Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s roof failures split by ZIP in a way neighboring cities don’t. The 1940s-to-1970s slab-foundation tracts in 91762 and 91764, the neighborhoods radiating off Euclid Avenue and Holt Boulevard, have deck and flashing issues tied to aging sheathing. These homes were framed when plywood decking wasn’t standard; many still have spaced board sheathing or skip sheathing that moves under load. Put a new CertainTeed shingle on that—something we handle differently than CertainTeed repair in Chino—and you’ll see telegraphing, popped nails, and flashing failures within a few seasons. The scope there is structural before it’s cosmetic. Down near the newer infill by 91761, the same CertainTeed call looks completely different. Those homes have modern sheathing and seismic detailing. What fails there first is edge and valley flashing under Santa Ana gusts, because wind exposure at exposed corners exceeds what a standard nailing pattern was designed for. So the same Landmark shingle, the same installer, the same city, two entirely different jobs. We quote them differently because they are different. Most roofers in the Inland Empire give you one generic pitch. We give you the scope that matches your actual building stock.
CertainTeed Models & Products We Service in Ontario
We install and service the CertainTeed roofing and exterior lines that make sense for this market: Landmark architectural shingles as the workhorse for most Ontario homes, Presidential Solaris cool-roof shingles where UV reflectivity matters on big west-facing planes, WinterGuard waterproofing underlayment at valleys and eaves, and Monogram vinyl siding for exterior cladding. For parts, we use CertainTeed accessory components, Ridge Vent, matching hip-and-ridge, the correct flashing details, where they actually affect wind and water performance. We won’t upsell OEM accessories that add cost without adding protection. And we won’t use aftermarket parts on critical waterproofing assemblies. The distinction matters: an aftermarket ridge vent is fine on a straightforward gable. It’s not fine on a valley intersection that takes Santa Ana-driven water. We stock the CertainTeed products most often needed for fast turnaround in Ontario, so a post-storm repair doesn’t wait on a supplier’s timetable.

AfterCertainTeed Service Pricing in Ontario
Here are our current market-calibrated ranges for CertainTeed work in Ontario. These are honest ballparks, not quotes. Your exact number depends on roof size, pitch, deck condition, and how much flashing work the existing roof needs.
| Service | Price Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Metal Roof Installation | $15,000 – $40,000 |
What drives cost on an Ontario CertainTeed job is rarely the shingle itself. It’s what’s underneath: deck replacement on a 1950s ranch runs more than a simple overlay on a 2010 subdivision home. Flashing rebuilds at valleys and penetrations add labor. Wind-rated nailing patterns take more time but cost the same in materials. Our free estimate includes a written line-item quote, a deck inspection, and a punch list of what’s actually failing. Call (855) 901-7266 to schedule yours.

FAQs – CertainTeed Construction in Ontario
Yes, on exposed planes. Ontario’s high-desert UV load and summer heat bake oxidized asphalt hard. A south- or west-facing Landmark roof here can show granule loss and surface cracking 5 to 8 years earlier than the same product on a shaded slope or in a coastal city. That doesn’t mean the product is bad; it means the detailing and ventilation have to be right. Call (855) 901-7266 if you want us to assess your exact exposure before you decide on repair versus replacement.
Probably at least partial new sheathing. Most original decks in 91762 and 91764 use spaced board or skip sheathing that doesn’t meet modern nailing standards for wind-rated shingle installation. We won’t lay Landmark over a deck that moves. We’ll quote the sheathing work as a separate line item so you see exactly what’s structural and what’s cosmetic. Call (855) 901-7266 for a deck inspection before you sign anything.
Look at the failure pattern. If shingles lifted at eave and rake edges but the field is intact, you likely need a targeted repair with wind-rated nailing and new flashing. If granule loss is widespread and the deck is saturated, you’re looking at replacement. Our rule in Ontario is: repair what can honestly be repaired, replace what can’t. We’ll tell you which after we walk the roof. Call (855) 901-7266 and we’ll give you a straight answer.
It depends on the structure and the exposure. Metal roofing handles Ontario’s UV and heat load better than asphalt over the long term, and it resists Santa Ana uplift well when the panel profile is rated for the wind zone. On a warehouse-adjacent building with a low-slope or standing-seam profile, it’s often the right call. On a 1950s tract home with a steep gable, Landmark is usually the better value. We’ll price both honestly. Call (855) 901-7266 for a comparison quote.
No. We’re an independent general contractor that installs and services CertainTeed products. We are not manufacturer-affiliated or part of a CertainTeed-authorized program. What that means for you: we recommend what’s actually right for your Ontario roof, not what a manufacturer incentive program pushes us toward.
