CertainTeed Roofing in Ontario, CA | Moreno Valley Roof Repair
We provide independent CertainTeed service in Montclair and across Ontario, CA, covering everything from Landmark shingle repair to full tile underlayment replacement. The thing that makes our CertainTeed work different here is simple: Ontario’s heat and Santa Ana winds don’t treat roofs the way coastal SoCal does, and we plan every job around that reality. Call (866) 217-3967 for a free estimate. We’ll tell you what the roof needs, not what sounds like a bigger job.
Why Ontario Residents Choose Us for CertainTeed Service
Ontario homeowners don’t need a roofer who dabbles in CertainTeed. They need someone who knows how Landmark shingles behave after five Inland Empire summers and what a 40-year-old RoofRunner underlayment looks like when it comes apart under concrete tile. That’s the work we do every week. Ruben Ibarra grew up in Sunnymead Ranch and has spent nearly three decades watching roofs take this heat, so when we show up to a home off Euclid or Holt, we already know what the south-facing slope is likely to show us.
We carry no manufacturer authorization, and that’s the point. Our CertainTeed sales & service is driven by what your roof actually needs, not by a brand program pushing a specific product. If a repair will hold, we’ll say so. If the roof is done, we’ll say that too. We use OEM-compatible CertainTeed materials when a factory match matters, and quality aftermarket flashing and vent boots where they genuinely outperform. One contractor, three services: repair, replacement, and standalone inspection. No referrals, no runaround.

Common CertainTeed Roofing Problems We Solve in Ontario
CertainTeed makes solid products, but Ontario’s climate punishes every roof system in specific, predictable ways. Here’s what we see most often:
- Embrittled Landmark shingles cracking along ridges and south-facing slopes. Sustained 100°F+ UV exposure bakes the asphalt until it loses its flexibility, and the first place you’ll see cracks is where the shingle bends over the ridge or takes direct afternoon sun. This is the most common CertainTeed failure mode in Ontario, full stop.
- Seal-down strips releasing so tabs lift in Santa Ana winds. Thermal cycling from hot days to cool nights weakens the adhesive bond, then a 50-mph gust gets under the tab and creases it. Coastal roofs don’t see this nearly as often because the temperature swings are smaller.
- Dried-out CertainTeed tile underlayment failing beneath intact concrete tile. Around 91762 and the older stucco tracts, the underlayment is often original to the 1970s or 80s. It’s now 40+ years old, past its service life, and it tears during monsoon downpours while the tile on top still looks fine from the ground.
- Cracked or shifted ridge and hip tiles over CertainTeed tile systems. Wind events knock ridge tiles loose or crack them at the mortar joints. Once that happens, water gets underneath, the flashing dries out, and the next rain finds a way in.
- Flashing and valley failures that started as small gaps. Ontario’s brief but intense monsoon rains exploit every dried-out flashing seam and underlayment gap. What looks like a shingle problem is often a flashing problem two feet away.
CertainTeed Service in Ontario: What Local Conditions Mean for Your Equipment
Here’s the thing about Ontario that changes how CertainTeed roofing work plays out here: the 91762 stucco tract homes carry concrete tile roofs whose underlayment is now 40+ years old, well past its service life. The tile is often fine. The dried-out underlayment underneath is the actual leak source. That means tile-lift-and-relay underlayment work is the dominant residential roofing job in this part of Ontario, not shingle replacement. We pull the tile, replace the underlayment with new CertainTeed RoofRunner or DiamondDeck, reset and re-fasten the original tile, and re-flash the valleys. The homeowner keeps their tile and gets a watertight roof without paying for a full tile replacement. After a Santa Ana wind event in the 91762 stucco tracts, our crew pulled cracked ridge tiles and found the original concrete-tile underlayment dried to a brittle sheet that tore at the lightest touch. We replaced the underlayment on the affected slopes, reset the existing tile, and re-flashed the valleys so the next monsoon rain had nothing to find. That’s the job Ontario asks for most, and it’s the one we’re best at.
CertainTeed Models & Products We Service in Ontario
We work on the full CertainTeed residential lineup: Landmark, Landmark 30, and Landmark Pro architectural asphalt shingles; Presidio, Presidential, and Northgate premium architectural shingles; and Xtreme2 and Landmark IR reflective shingles on Inland Empire tract homes. On the tile side, we replace RoofRunner and DiamondDeck underlayment systems beneath barrel and flat concrete tile. We match failures to the right CertainTeed line when a factory match matters, and we stock common underlayment rolls, ridge tiles, and flashing profiles locally so Ontario jobs don’t wait on freight. When a shingle roof is past 18 to 20 years and the south slope is cracking, we’ll tell you straight that spot repair is throwing money away. Replacement is the honest call.

AfterCertainTeed Service Pricing in Ontario
CertainTeed repair in Chino and Ontario follows similar pricing that depends on what the roof actually needs. Tile underlayment replacement typically runs $3.50 to $6.00 per square foot of affected slope, including underlayment, re-fastening, and flashing work. Shingle replacement on a repair basis generally falls between $450 and $1,200 depending on the number of slopes and accessibility. Full shingle re-roofs with Landmark architectural shingles run $5.50 to $8.00 per square foot. What drives the cost here is underlayment access: if we’re pulling and resetting tile on a 35-year-old roof, the labor is different than a straightforward shingle tear-off. Every estimate is free, and it’s a written line-item quote, so you see exactly what you’re paying for before any work starts. Call (866) 217-3967 for an exact quote, estimates are free.

FAQs – CertainTeed Roofing in Ontario
The leak is almost certainly in the underlayment, not the tile. Ontario’s 91762 stucco tracts were built with concrete tile over underlayment that is now 40+ years old, far past its service life. The underlayment dries out, becomes brittle, and tears during monsoon downpours while the tile on top still looks intact. The fix is tile-lift-and-relay underlayment replacement: pull the tile, replace the underlayment, reset and re-fasten the tile, and re-flash the valleys. Call (866) 217-3967 for a free inspection if you see water stains but no cracked tile.
Ontario’s sustained 100°F+ summer heat bakes the asphalt in CertainTeed shingles until it loses flexibility. The south slope and ridge caps take the most direct UV and thermal stress, so those are the first places the shingle material embrittles and cracks. Landmark shingles are well-made, but no asphalt shingle escapes this climate pattern indefinitely. If you’re seeing cracks on a roof that’s 15 years old or older, call (866) 217-3967 and we’ll tell you whether repair or replacement makes sense.
No, Ontario’s heat alone does not void a CertainTeed warranty. CertainTeed’s warranty covers manufacturing defects, and normal UV aging is expected. However, improper installation, poor attic ventilation, or unapproved repair materials can affect warranty coverage. That’s why we match failures to the right CertainTeed shingle line and install to factory specs. If you’re unsure about your roof’s warranty status, call (866) 217-3967 and we’ll assess what’s actually going on before you spend a dollar.
Santa Ana winds exploit weaknesses that Ontario’s thermal cycling creates. Hot days and cool nights loosen the seal-down strips on CertainTeed shingles, and then high winds lift and crease the tabs. Once tabs are creased, they don’t reseal properly, and the next wind event makes the problem worse. We check seal-down integrity as part of every repair and replacement job in Ontario. Call (866) 217-3967 after any major wind event if you suspect lifted tabs.
You can, in most cases. CertainTeed’s color lines have stayed consistent across many product generations, and we can typically match Landmark or Landmark Pro shingles for a spot repair. The bigger question is whether spot repair is worth it; if the shingles around the repair are already embrittled from Ontario sun, you’re patching a deteriorating slope. We’ll give you an honest assessment, not a sales pitch. Call (866) 217-3967 for a free estimate and we’ll show you what we find.
