CertainTeed Roofing in Pomona, CA | Van Nuys Roofing Co
Roof Repair in Pomona with CertainTeed means one thing most of the time: shingles that lifted, cracked, or blew off after a Santa Ana wind event, very often on an older home that still has original skip sheathing underneath. We’re Van Nuys Roofing Co, and we repair and replace CertainTeed roofs across Pomona’s 91766, 91767, 91768, and 91769 ZIP codes. Call (866) 321-6172 for a straight answer on what your roof actually needs.
Why Pomona Residents Choose Us for CertainTeed Service
We’ve re-roofed and repaired CertainTeed in Covina and across the San Gabriel Valley. That’s not a marketing line. It means we know how Landmark architectural shingles actually hold up under Pomona sun and Santa Ana wind, not how they look in a showroom brochure. As an independent contractor, we work on the product, not for the manufacturer. No authorization, partnership, or warranty endorsement implied. What we bring is familiarity with the material itself: how the asphalt ages, how the tabs seal, where the weak points show up first on a 1940s Craftsman roof in the 91767 flats.
Rick Dominguez runs our operation, and he grew up off Sepulveda Boulevard in Van Nuys, a few blocks from the old municipal airport. He’s spent the better part of two decades on rooftops across the San Fernando Valley and CertainTeed service in Walnut, and he’s known for being straight with people about what actually needs fixing versus what can wait another season. His rule is simple: if it doesn’t need replacing, he’s not going to tell you it does. That’s the standard we bring to every CertainTeed roof we touch in Pomona. We inspect first, recommend second.

Common CertainTeed Roofing Problems We Solve in Pomona
CertainTeed shingles are solid products. But every roof product has predictable failure points, and in Pomona those failures follow a pattern we’ve seen enough times to fix quickly and correctly.
- Wind-lifted tabs and lost ridge caps. After a Santa Ana blow, west-facing slopes in the 91767 flats lose shingle tabs and ridge caps at a rate that surprises homeowners. CertainTeed Landmark and Presidential Shake tabs, especially when the sealant strip has aged, catch wind and peel back. We re-secure or replace the damaged courses and address whatever let the wind get beneath them in the first place.
- UV degradation and granule loss. Pomona’s hot inland summers dry out the asphalt layer in aging CertainTeed three-tab shingles, especially XT 25 and XT 30. The granules loosen and wash into gutters, and the fiberglass mat starts to show through. Once that’s visible, the shingles are past their serviceable life. We’ll tell you plainly when that’s the case.
- Nail pops on skip sheathing. Pre-1950s wood-frame and stucco homes in Pomona, particularly in 91766 and 91767, often have original 1×4 skip sheathing with gaps between the boards. CertainTeed shingles nailed over those gaps don’t always bite wood, so nail pops and deck deflection develop. Water follows the nail hole. We re-nail carefully and repair or replace the decking where it has failed.
- Flashing and vent boot failures that masquerade as shingle leaks. On Craftsman-era roofs, water often enters at pipe penetrations, chimneys, or wall junctions long before shingles fail. We trace the leak to where it actually originates. In Pomona, a “shingle leak” is just as often a rotted vent boot or a bad piece of step flashing.
- Granule buildup and gutter clearing after re-roofs. New CertainTeed shingles shed some granules in the first months. Older shingles shed more. On Pomona homes with box gutters, that can mean clogged downspouts. We check gutter flow when we finish a repair or replacement.
CertainTeed Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the thing most roofing pages never mention about Pomona: many homes in 91766 and 91767 still sit on original 1×4 skip sheathing, not solid plywood or OSB decking. That changes what a “simple shingle-over” looks like. A straight CertainTeed shingle re-roof over skip sheathing isn’t always valid. The boards need careful re-nailing first, and in spots where dry rot or deflection has set in, they need sistering or full replacement with solid decking before the new shingles go down. That’s a different scope of work than what you’ll find on the newer tile roofs in neighboring cities like Claremont or Chino. If a contractor gives you a shingle-over price without ever walking the roof and checking the decking, you’re getting a number, not an estimate. We’ve pulled damaged shingles on 1940s bungalows near Garey Avenue and found gaps in the skip sheathing wide enough to drive a nail straight through to open air. That’s why our CertainTeed sales & service approach always starts with what’s underneath the shingles.
CertainTeed Models & Products We Service in Pomona
We work across the CertainTeed shingle lines that show up most often on Pomona roofs. Landmark architectural shingles are the workhorse in the area, and we match profile and color when wind damage requires isolated slope repairs. XT 25 and XT 30 three-tab shingles are common on the post-war tract homes across Pomona, and when they’ve reached the end of their granule-bearing life, we can re-roof with a modern architectural upgrade. Presidential Shake is the premium line we see on larger properties, and we know its heavier profile needs proper nailing patterns and decking support to hold up in Santa Ana wind. Underneath, we use Flintlastic SA self-adhered underlayment where the roof design calls for it, plus quality synthetic underlayment on standard slopes. We don’t substitute cheap materials because we’ve seen what cheap underlayment looks like after two Pomona summers. We match CertainTeed shingle profiles with genuine or spec-equivalent product, and we stock common profiles locally so Pomona repairs don’t wait on a distributor’s two-week lead time.

AfterCertainTeed Service Pricing in Pomona
A few specific numbers to work from, based on what restoration work actually costs in the Pomona market:
- Roof inspection (standalone, no repair required): $120 – $250
- Small repair, shingle replacement: $200 – $600
- Aluminum or Galvalume restoration: $2,500 – $6,000
- Sheet metal fabrication, custom flashing: $500 – $2,000
What drives the cost on a CertainTeed repair in Pomona is whether the decking underneath is shot. A wind-lifted slope with good decking is a quick, affordable fix. A slope with dry-rotted skip sheathing means re-nailing, sistering, and re-decking before shingles go back on. That’s honest scope, not a change order. Our free estimate walks you through what we found on the roof and what it costs, line by line. Call (866) 321-6172 to schedule yours.

FAQs – CertainTeed Roofing in Pomona
Not always. Original 1×4 skip sheathing with wide gaps means some shingle nails land on nothing, which causes nail pops and wind-lift. We re-nail the existing boards first, and where the boards have dry rot or deflection in Pomona’s older 91766 and 91767 homes, we sister new wood alongside or replace the decking section before shingling. A straight shingle-over on failing skip sheathing will cost you more in five years than doing the decking right the first time. Call (866) 321-6172 and we’ll inspect what you actually have.
Most ridge cap failures in Pomona come from a combination of aged sealant, worn cap shingles, and wind angles that hit west-facing ridges hard. Once the cap shingles lift at the edge, the wind peels them back and more follow. We replace missing ridge caps with matching CertainTeed product and check the cap fastening pattern, since older Pomona roofs often had caps nailed with the wrong exposure. Call (866) 321-6172 if another Santa Ana took your ridge with it.
On Pomona’s Craftsman-era and bungalow roofs, leaks at penetrations are usually flashing or boot problems first. Shingles rarely fail first. We trace the watermark from the attic or interior, then inspect the pipe boot, chimney flashing, or wall step flashing. The fix is often a new boot and step flashing rather than shingle replacement. We’ll show you what we found before we do anything. Call (866) 321-6172 if you’re seeing water inside after the winter rains.
Yes. Pomona’s hot inland summers push roof surface temperatures well over 150 degrees on summer afternoons, which accelerates asphalt drying and UV degradation. CertainTeed shingles wrinkle, lose granules faster, and pull away from the sealant strip sooner than the same shingle on a coastal roof. The dry climate means less moss, but more thermal expansion and granule loss. Pomona homeowners should expect the lower end of the manufacturer’s life range, not the upper. Call (866) 321-6172 to find out where your roof is on that curve.
Yes. Most of our CertainTeed work in Pomona is repair and replacement on roofs installed by other contractors years ago. We know the product lines well enough to match shingle profile and color for wind repairs, and we’re honest about when a patch makes sense versus when the whole field needs replacement. Repair or replace, we’ll tell you which one actually makes sense. Call (866) 321-6172 to schedule a look.
