CertainTeed Construction in Montclair, CA | Workshop Contractors
We handle CertainTeed roofing and exterior work across Montclair as an independent contractor. We install and repair Landmark shingles, Cedar Impressions siding, and full roof assemblies, and the thing that sets our CertainTeed work apart in this city is knowing how mid-century tract homes and tight rear-line garages affect the roof scope. If you’re dealing with granule loss, wind-driven leaks, or a garage conversion that needs re-decking, call (844) 384-3361 for a free estimate.
Why Montclair Residents Choose Us for CertainTeed Service
CertainTeed makes a solid product, but any shingle only performs as well as the deck and underlayment beneath it. Montclair’s 1950s-to-1970s tract stock tests that constantly. Noel Figueroa, our owner and general contractor, grew up in Ontario’s Vineyard neighborhood watching the same generation of tradesmen frame those postwar houses, and he still approaches every Montclair roof the way those crews did: look at what’s underneath first. We also offer CertainTeed repair in Ontario for homeowners there.
We’re not a CertainTeed-authorized dealer or installer, and we tell homeowners exactly that. What we are is a CertainTeed sales & service contractor who has torn off enough failing assemblies in the Pomona Valley to know when a repair will buy five more years and when it’s a waste of money. We use genuine CertainTeed shingles, underlayment, and accessory components matched to the manufacturer’s assembly specs. Generic substitution just to hit a lower number isn’t how we work.
Because we’re local to the Montclair service area, we know what a 1963 stucco-and-wood-frame house on a 5,000-square-foot lot should look like under the felt. That matters more than a showroom brochure ever will.

Common CertainTeed Construction Problems We Solve in Montclair
- Granule loss and tab lifting on Landmark shingles. Santa Ana events hit Montclair’s exposed south and west roof planes hard. We see Landmark shingles that look ten years old after five because wind-driven sand and debris abrade the granule surface. Repair means sealing or replacing the compromised slope, not just sweeping granules into the gutter and calling it done.
- Brittle, failed underlayment on original tract roofs. The 1950s-70s homes across Montclair were built with felt underlayment that was never designed for sixty-plus years of Pomona Valley summer heat. When we lift shingles and the felt crumbles in our hands, the only honest fix is a tear-off and new synthetic underlayment before new CertainTeed shingles go down.
- Wind-driven rain intrusion at valleys and step flashing. Low-slope additions and converted-garage roofs are everywhere in Montclair. Winter storms push water sideways at the valley intersections, and once flashing is compromised, staining shows up on the ceiling inside. We re-flash and re-seal these transitions to CertainTeed’s assembly specs.
- Nail-popping and uneven shingle courses over old sheathing. When a Montclair homeowner has had a “new” roof laid over skipped or uneven decking, the CertainTeed product gets blamed for what is really a substrate problem. We correct the decking before the shingles go on.
- Garage conversions that outrun the roof. The rear-garage ADU wave through the 91763 core means dozens of converted structures with original 1960s roof assemblies. Re-decking, re-venting, and re-roofing to CertainTeed specs is a required part of the conversion, not an optional upgrade.
CertainTeed Service in Montclair: What Local Conditions Mean for Your Equipment
On Montclair’s small postwar lots near the 91763 core, original detached garages often sit within inches of the rear property line. That one fact changes how we scope nearly every CertainTeed garage-conversion roof in this city. Before we ever tear off the old shingles, we’re confirming setbacks and ordering a survey, because a garage that’s been there since 1958 isn’t automatically legal to convert just because it has walls. The city’s plan review for infill work accounts for tight lots and mid-century framing, and a conversion that ignores the property-line question creates a title and permit mess for the homeowner later.
What that means for the CertainTeed assembly itself is simple: the roof scope and the survey question are the same conversation. We’ve torn off wind-abraded Landmark shingles over a detached rear garage in the 91763 core only to find dried-out felt and uneven sheathing underneath. The first step wasn’t roofing. It was confirming setbacks with the survey in hand. Then we re-decked, re-vented, and installed new Landmark shingles to CertainTeed’s specs. The converted space passed inspection and stopped the winter staining at the valley that had plagued the previous assembly.
CertainTeed Models & Products We Service in Montclair
We install and repair the CertainTeed lines most common on Montclair homes: Landmark series architectural asphalt shingles for standard re-roofs, Presidential Shake luxury shingles for homeowners who want a heavier shadow line, Cedar Impressions siding for exterior cladding, and CertainTeed vinyl soffit and fascia systems that finish the eave lines on converted garages and additions.
When we repair, we match the existing product rather than patching with whatever bundle is on the shelf. If a Montclair home has Landmark Pro shingles on the front slope, that’s what goes back on the repair area. For accessory components like ridge vent, hip and ridge caps, and synthetic underlayment, we use CertainTeed-matched materials so the assembly carries through consistently. We stock common CertainTeed profiles for quick turnarounds in Montclair, and anything unusual we order directly and schedule around the delivery.

AfterCertainTeed Service Pricing in Montclair
Here’s where CertainTeed construction work lands for Montclair homeowners. These are market-calibrated ranges for 2026, and they reflect local tear-off costs, dump fees, and the labor of re-decking mid-century houses that almost never have clean sheathing.

| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Garage Conversion | $30,000 – $80,000 |
What drives the number is decking condition, roof complexity, and whether the garage conversion triggers new shear wall, electrical, or setback work before the roof even matters. Our free estimate includes a written line-item scope so you see exactly what you’re paying for. Call (844) 384-3361 to schedule yours.

FAQs – CertainTeed Construction in Montclair
In most cases, yes, but the property-line question gets answered before the roof question. A detached garage inches from the rear line means we need a current survey and setback confirmation from the city’s planning department before pulling permits. Once that clears, we re-deck and re-vent the assembly to CertainTeed specs and roof it as part of the conversion scope. For similar work in the next town over, see our CertainTeed repair in Upland. Call (844) 384-3361 and we’ll walk you through what your specific lot requires.
On Montclair homes, the usual cause is repeated Santa Ana wind abrasion on exposed south and west roof planes. Granule loss isn’t always a manufacturer defect; it’s often environmental. We’ll inspect the slope, check for tab lifting and nail-popping, and tell you honestly whether you need a repair or a replacement. The inspection is part of a free estimate at (844) 384-3361.
Most Montclair tract homes need a full tear-off. The original felt underlayment on these 1950s-70s houses is almost always dried out and brittle from decades of Pomona Valley heat. Shingling over it buries a problem that leaks through to your ceiling in the next winter storm. We’ll confirm with a deck inspection, but plan on a tear-off.
Yes, when the assembly underneath is right. Low-slope additions fail at the valleys and step flashing first, not the shingles themselves. We install CertainTeed shingles to the manufacturer’s wind rating and nail schedule, but we also replace underlayment and re-flash the transitions where Montclair’s wind-driven rain actually gets in. Call (844) 384-3361 and we’ll inspect the whole assembly, not just the shingle surface.
Expect uneven or skipped sheathing, brittle felt, and possibly some framing that’s moved over sixty years. We correct the decking before new CertainTeed shingles go down. Sometimes that means re-nailing the entire deck, sometimes replacing sections. It adds cost, but it’s the difference between a roof that lasts twenty-five years and one that fails in five. Build it right the first time. The second time costs twice as much and nobody’s happy about it.
