Millwright Builders works with CertainTeed products daily, but we’re not a manufacturer arm. We’re a licensed general contractor in Pomona who specifies, installs, and repairs CertainTeed roofing, siding, and trim because the material performs when it’s detailed correctly. The catch with CertainTeed, like any system, is that performance depends on installation quality and knowing how local conditions stress the product. On a 1920s bungalow near Lincoln Park, we found the original CertainTeed Landmark shingles had failed along the south-facing slope due to sun damage, and the underlying skip sheathing was deteriorating. We pulled the old roof, replaced the sheathing, and installed a new Landmark system with enhanced underlayment and proper flashing. During tear-off, we found an unpermitted rear addition, which we helped the homeowner permit and bring up to code before final inspection. That’s the kind of job that defines CertainTeed work in Pomona: the product matters, but the house underneath it matters more.

Noel Castañeda, our owner, started his construction training at Skyline College and spent nearly two decades on residential and light commercial work before founding Millwright Builders. He’s the reason we don’t rush a CertainTeed install and why our job sites are cleaner at the end of the day than when we arrived.

Why Pomona Residents Choose Us for CertainTeed Service

Most Pomona homeowners with a CertainTeed roof or siding system don’t need a product pitch. They need a contractor who understands why the product is failing and whether it should be repaired or replaced. We carry genuine CertainTeed accessories, including ridge caps, starter strips, and underlayments, when they’re available and appropriate. We also use high-quality aftermarket flashing and fasteners that meet or exceed manufacturer specifications where they make more sense. That’s not a compromise. It’s an honest assessment of what will actually hold up on a pre-1970s Pomona house.

Our crews know the difference between a Landmark shingle that’s simply aged and one that’s been cooked by a west-facing Pomona summer, and we handle CertainTeed repair in Montclair too. We know what Santa Ana wind uplift does to rake edges. And we know how to sequence a roof or siding job so that if an unpermitted addition shows up, code enforcement doesn’t stall the whole project. Pomona is not a new-construction market. It’s an older, built-out city where most work is remodel, addition, and repair, and we work accordingly.

Common CertainTeed Construction Problems We Solve in Pomona

• Heat-driven granule loss on Landmark shingles. West- and south-facing roof planes in Pomona take brutal afternoon sun from May through October. Granule loss accelerates, the asphalt layer gets brittle, and the shingles start to cup. We replace before the underlying decking rots.
• Wind uplift and shingle blow-off during Santa Ana events. Rake edges and ridges catch the worst of it, especially where original fastening was underdriven or misplaced. Pomona sits in the wind path that hits the eastern San Gabriel Valley hard, and older CertainTeed installs often lack enough fasteners per shingle.
• Moisture intrusion at roof-to-wall junctions on stucco homes. The 1940s-60s tract houses across east and south Pomona have stucco walls meeting roof planes with minimal flashing. Decades of heat cycling opens gaps, and winter rain gets behind the wall. We reflash and repair before the rot spreads.
• Fading and cracking vinyl siding on citrus-era outbuildings. Many deep east-side lots still have old packing sheds or garages converted to living space or storage. CertainTeed vinyl siding on those structures, often unventilated and uninsulated, chalks and cracks faster than the same product on a properly built wall.
• Failed underlayment on low-slope sections of older roofs. Pomona’s early-1900s Craftsman and bungalow blocks near downtown often have low-slope porch roofs or additions where the original underlayment degraded. Water gets in at the transition, and the CertainTeed shingles above look fine while the structure below is failing.

CertainTeed Service in Pomona: What Local Conditions Mean for Your Equipment

Here’s the thing about Pomona that doesn’t apply in Claremont or Chino: deep east-side lots frequently contain unpermitted citrus-era outbuildings, garages, and additions behind the main house. These structures were built decades ago, sometimes converted to living space without permits, and they’re often discovered mid-project. That matters for CertainTeed work because a roof or siding permit on the main house can trigger a review of the entire parcel. Pomona’s code and inspection culture is different from the fast-growing Inland Empire cities to the east where new construction dominates. Here, you’re often dealing with retroactive permitting, seismic evaluation on old wood frames, and lead or asbestos issues on pre-1970s structures. We plan for that from the first site visit. On CertainTeed roof replacements, we sequence the permit, the tear-off, and the inspection so the job doesn’t stall when an unpermitted addition turns up. We’ve helped homeowners bring those additions up to code before the final sign-off, which is not something every roofing crew is prepared to handle.

CertainTeed Models & Products We Service in Pomona

We install and repair the CertainTeed lines most common on Pomona homes. Landmark shingles cover the majority of our roof work, from full replacements to targeted repairs. Presidential Shake shows up on higher-end homes where the owner wants the look of wood without the fire risk. On the siding side, we work with Monogram vinyl and CedarBoards insulated siding, both of which appear on postwar tract houses and citrus-era conversions. When we repair, we use genuine CertainTeed accessories where the warranty and aesthetics depend on it. When the repair requires flashing or fasteners, we source aftermarket components that meet or exceed spec instead of charging a premium for a branded box. The goal is a repair that lasts, not a parts invoice that looks impressive.
