CertainTeed Roofing in Pomona, CA | Orange County Roofing Co
We provide independent CertainTeed roofing service across Pomona, from 91768 down through 91766, and CertainTeed service in Claremont as well. The thing that sets our CertainTeed work apart here is that we actually understand what those shingles go through in this particular valley: afternoon heat that bakes south and west slopes well past 100°F, and Santa Ana wind cycles that pry at ridge caps and sealant strips. We’re not a CertainTeed dealer. We’re the roofer Pomona homeowners call when a CertainTeed roof starts showing its age. Call (866) 942-4187 for a straight diagnostic.
Why Pomona Residents Choose Us for CertainTeed Service
We carry seven major shingle brands, GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so when we look at your roof, there’s no incentive to steer you toward a product that pays us better. CertainTeed gets recommended when it fits the house, the slope direction, and the budget. Not because a distributor’s rep bought us lunch. Kurt Hensley started this company after years of watching Orange County crews treat brand loyalty as a substitute for honest diagnosis. He’s kept that out of our work in Pomona. When a CertainTeed roof needs repair, we repair it. When replacement makes more sense, we’ll show you the numbers and let you decide.
Our CertainTeed sales & service work leans on OEM shingles, ridge caps, and starter strips where they’re available and genuinely the right part. But we’ll also tell you when a quality aftermarket boot or underlayment is the more durable fix. That’s the difference between a roofer who works for a brand and one who works for the homeowner.
We cover all of Pomona service area, from the pre-war bungalows near downtown to the mid-century tracts in the 91766 and 91767 ZIPs. One team handles inspection, repair, and full replacement, so you’re not vetting three different crews at three different stages.

Common CertainTeed Roofing Problems We Solve in Pomona
These are the calls we run in Pomona week after week. Each one ties directly to the way this valley treats a roof:
- Granule loss and curling on south- and west-facing Landmark slopes. The afternoon sun in the 91766 and 91767 tracts is unforgiving. We see CertainTeed Landmark shingles where the asphalt mat has baked hard, the edges have curled, and granules are washing into the gutters. By the time you notice the bald patches, the shingle has already lost most of its UV protection.
- Lifted ridge caps and wind-scoured tabs on XT 25 roofs near the foothill edge. Santa Ana gusts funnel down the San Gabriels and hit the north and east edges of Pomona hard. Ridge caps are the first thing to go. A lifted ridge cap catches more wind, then more, until it’s gone entirely and water’s running the ridge line.
- Flashing and vent-boot failures across Presidential and Landmark systems. Dry heat shrinks sealant. Rubber boots around plumbing stacks crack after a decade of 100°F summers and a few cold winter snaps. The gap looks small from the ground, but it’s a direct path for the next winter rain.
- Underlayment fatigue and dry-rot at the fascia on older Pomona homes. If your CertainTeed roof sits over original plank sheathing and the attic’s poorly vented, heat builds from below and cooks the deck. We open these roofs and find underlayment that crumbles like newspaper, with fascia soft enough to push a thumb through.
- Skip-sheathing problems on 1950s composition roofs. Many Pomona tract homes have original 3-tab or early architectural shingles nailed over skip-sheathing, boards with gaps between them. When shingles get brittle and pull away, there’s often no solid nailing surface left to work with. We have to address the deck before any new shingle can be warrantied.
CertainTeed Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the thing a generic CertainTeed page won’t tell you. Pomona’s 91766 and 91767 tract homes frequently have CertainTeed 3-tab or early architectural shingles nailed over skip-sheathing. That’s a 1950s and 60s construction shortcut where the deck boards were laid with gaps, not tight together. It worked fine when shingles were thick and fasteners were nail-driven by hand. It’s a problem now, because a new architectural shingle needs a solid, continuous nailing surface to meet manufacturer warranty requirements. So when we replace a sun-baked south slope on one of these homes, we often have to add solid decking before the new CertainTeed shingle goes down. That adds a line item to the quote, but skipping it means the manufacturer can deny a future warranty claim and the shingle won’t seat properly. This condition is rare in Corona or the neighboring foothill cities, where full plank or plywood decks are standard. Pomona has it concentrated in the old tract blocks, and we’ve learned to look for it before we ever write an estimate.
CertainTeed Models & Products We Service in Pomona
We work on the full certainTeed residential lineup you’ll find across Pomona rooftops. That includes Landmark architectural shingles, the most common product on mid-century and newer homes; XT 25 3-tab shingles, which we still see on original 1950s-70s composition roofs; Presidential Shake luxury shingles on higher-end properties; and Prism architectural shingles where homeowners wanted a deeper shadow line. For repairs, we use CertainTeed OEM shingles, ridge caps, and starter strips when they fit the roof and are available locally. For vent boots, flashing, and underlayment, we’ll match a quality aftermarket part when it’s the more durable call. We keep common Landmark colors and accessory components moving through our Pomona jobs regularly, which means we can match most roofs without waiting on a special order.

AfterCertainTeed Service Pricing in Pomona
CertainTeed roofing service in Pomona generally breaks down like this:
- Shingle replacement (isolated damage): $350-$650 depending on slope accessibility and how many shingles need matching.
- Vent boot replacement: $180-$350 per boot, including new flashing and sealant.
- Flashing repair (chimney or wall flashing): $400-$900 depending on how much needs to be cut out and re-fabricated.
- Ridge cap repair or replacement: $450-$1,100 depending on run length and wind damage extent.
- Full CertainTeed re-roof with decking correction: $12,000-$24,000+ on Pomona homes, with the decking line item varying based on whether we’re repairing skip-sheathing or laying fresh plywood.
What drives cost here more than anything is the deck underneath. Two identical Landmark quotes can be $2,500 apart if one house needs solid decking added over skip-sheathing and the other doesn’t. That’s why our free estimates include an attic inspection where we can see the deck from below. Call (866) 942-4187 and we’ll give you exact numbers, written out, before any work starts.

FAQs – CertainTeed Roofing in Pomona
Twelve to fifteen years is short for a Landmark shingle under normal conditions, but Pomona’s inland-valley climate is not normal conditions—just as we see with CertainTeed service in Walnut. Sustained 100°F summer heat combined with intense UV on south and west slopes oxidizes the asphalt mat faster than coastal air ever would. When you add poor attic ventilation, which many 91766 and 91767 tract homes have, the shingle gets cooked from both sides. We can often extend the life with targeted repairs, but once granule loss is widespread, replacement is the better money. Call (866) 942-4187 for an honest read on where your roof stands.
Usually a repair. Lifted ridge caps are the most common Santa Ana call in Pomona, and in most cases we can re-secure and reseal them with new OEM ridge caps, provided the surrounding shingles are still intact. We’ll check the whole ridge line, because wind damage tends to run in patterns. If the shingle field below is sound, you’re looking at a targeted repair, not a re-roof.
No, not if you want the shingle manufacturer to stand behind the warranty. Skip-sheathing doesn’t provide the continuous nailing surface CertainTeed requires for their architectural lines. We add solid decking over the gaps before the new shingles go down. It’s not optional, and we’ll show you the manufacturer’s installation spec to back that up. It’s one of the most common line items on Pomona re-roofs.
For most Pomona homes, we recommend Landmark architectural shingles. They’re thicker than 3-tab, which buys you a few more years of UV resistance, and they’re available in lighter colors that reduce heat absorption. If the home is a higher-end property or you want the dimensional look, Presidential Shake is the premium option. We’ll talk through the cost difference in plain numbers, then you decide.
We use CertainTeed OEM shingles, ridge caps, and starter strips when they’re the right fit and available. For vent boots and flashing, we’ll often recommend a quality aftermarket part when it’s the more durable fix for Pomona’s heat and Santa Ana cycles. The shingle itself matters for warranty continuity. The boot material matters for longevity. We’ll explain the call either way.
