CertainTeed Roofing in Montclair, CA | Hawk Roof Repair
We provide independent CertainTeed roofing service across Montclair, CA. Our crews repair and replace CertainTeed shingle and flat-roof systems on the postwar tract homes that make up most of this city. The thing that sets our CertainTeed work apart here is that we know how Montclair’s heat, Santa Ana winds, and aging housing stock interact with these specific products – because we’ve been pulling failed CertainTeed roofs off Montclair homes for over a decade.
We’re not authorized by CertainTeed. We’re an independent contractor who works with seven major roofing brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – so the material recommendation you get is based on your roof, not a supplier contract. Noel Ibarra started Hawk Roof Repair after years working crews across the Inland Empire, and he’s built our reputation on catching failures before they become ceiling stains. Call (877) 731-1384 for a free estimate on any CertainTeed roof issue in Montclair.
Why Montclair Residents Choose Us for CertainTeed Service
CertainTeed has been making roofing materials since 1904, and their Landmark architectural shingles are among the most common products we see on Montclair homes. That matters because familiarity with a product line means faster diagnosis. When we walk a roof in the 91763 ZIP code, we already know what a west-facing Landmark slope looks like after fifteen summers of Pomona Valley heat. We know where XT 25 three-tabs crack first. We know what Flintlastic seam separation looks like after a winter of ponding.
We’re also local in a way that matters for service speed. Hawk Roof Repair operates out of the Inland Empire, so when a Montclair homeowner calls about a leaking valley or a lifted flashing, we’re not dispatching from two counties away. We inspect first. Every time. No ladder-top sales pitch. Our CertainTeed repairs use OEM shingles and accessories where they match the existing system, supplemented with quality aftermarket underlayments and fasteners when OEM parts are unavailable or cost-prohibitive. Noel grew up in the Sultana neighborhood of Ontario and learned roofing fundamentals through the construction trades program at Chaffey College – he knows this valley’s roofs because he’s lived under them his whole life, and he now offers CertainTeed repair in Ontario and surrounding communities.

Common CertainTeed Roofing Problems We Solve in Montclair
- Granule loss and blistering on Landmark shingles. Montclair summers routinely push past 100°F, and west-facing slopes take the brunt of that afternoon sun. When attic ventilation is poor, Landmark architectural shingles can blister and shed granules years before their rated lifespan. We see this constantly on the older ranch homes throughout Montclair’s postwar subdivisions.
- Tab-edge cracking on XT 25 three-tab shingles. The 1950s and 1960s tract homes in Montclair were often roofed with three-tab shingles, and after decades of expansion and contraction, the tabs crack at the edges. When Santa Ana winds hit, wind-driven rain finds those cracks and works into the deck. We replace these roofs with Landmark architectural shingles and proper underlayment.
- Seam separation and ponding leaks on Flintlastic flat roofs. Many low-slope sections in Montclair use self-adhered modified bitumen. When the underlying deck sags or drains clog, water ponds at low spots. After the first heavy winter rain, those ponding areas push water through separated seams. We patch Flintlastic membranes and rebuild drainage where needed.
- Deteriorated ridge caps and flashings. UV exposure in the Pomona Valley is relentless. Ridge caps on CertainTeed installations crack and curl, and flashings that were originally fastened with reused nails lift over time. This creates entry points at valleys and penetrations – exactly where water finds its way in.
- Failed repairs done by other contractors. We regularly find Montclair roofs where a previous contractor used mismatched shingle colors, incorrect fasteners, or aftermarket parts that don’t seal properly with the CertainTeed system. These repairs fail within a season or two. We correct them with proper OEM materials and correct installation methods.
CertainTeed Service in Montclair: What Local Conditions Mean for Your Roof
Here’s a fact about Montclair that shapes more CertainTeed roofing work than almost anything else: many of these postwar homes were built with original built-up roofs that later had a second layer of shingles laid over them – often without permits and without stripping the old roof first. When we’re called out to a 1958 or 1962 tract home near the Montclair Plaza area or in the neighborhoods south of the 10, we frequently find a shingle roof sitting on top of an old felt-and-tar roof. That hidden layer changes everything. It means the roof can’t simply be reroofed – code in California generally limits roofs to two layers, and many of these homes are already at that limit. To do it right, we strip down to the deck, inspect the sheathing, replace rotted sections, install new underlayment, and then put down the new CertainTeed system. This adds labor time and dump fees that homeowners don’t anticipate, but skipping it just means another failure in five years. If water found a way in, there’s a reason – and we’ll show you exactly where.
This is the kind of detail you won’t find on a generic roofing website. A contractor who does most of their work in newer cities or on bigger lots simply doesn’t encounter the layered-roof problem the way we do in Montclair’s older tracts. It’s a Pomona Valley reality.
CertainTeed Models & Products We Service in Montclair
Our crews work on every major CertainTeed line installed across Montclair homes. We service and replace Landmark architectural shingles (the dominant product on 1970s and newer roofs), XT 25 three-tab shingles (still present on hundreds of original postwar roofs), Flintlastic self-adhered modified bitumen (common on low-slope and flat sections), and Presidential SolarReflective shingles on higher-end reroofs. For parts, we use CertainTeed OEM shingles and accessories when they match the existing system, and we supplement with quality aftermarket underlayments and fasteners when OEM parts aren’t available or don’t make financial sense. We’ll tell you which is which and why. Our goal is a repair that holds, not a parts invoice that looks good.

AfterCertainTeed Service Pricing in Montclair
CertainTeed roof repair in Montclair typically runs between $350 and $900 for targeted work like flashing repair, valley fixes, or shingle replacement on a few slopes. Flat-roof patching on Flintlastic membranes usually falls between $400 and $1,100 depending on the size of the ponding area and whether deck repair is needed. Full reroofs with CertainTeed Landmark on a typical 1,400-square-foot Montclair ranch home generally start around $9,000 to $14,000, but the final number depends on how many existing layers we’re stripping, ventilation upgrades, and the condition of the deck.
What drives cost here more than anything is that hidden second layer. If your Montclair home has old built-up roofing under a shingle layer, the tear-off and disposal costs more. We give written, line-item estimates so you see exactly what you’re paying for. Call (877) 731-1384 to schedule a free estimate – we’ll walk the roof and show you what we’re seeing before any numbers come up.

FAQs – CertainTeed Roofing in Montclair
West-facing slopes in Montclair take direct afternoon sun during summer, when temperatures routinely exceed 100°F. When attic ventilation is inadequate, the heat builds up under the shingles and causes the asphalt to off-gas, creating blisters. The shingles then shed granules, exposing the mat to UV damage. The fix is usually a combination of improved ridge or soffit venting and replacing the blistered shingles. Call (877) 731-1384 and we’ll assess your specific slope.
Yes, in most cases. Flintlastic membranes can be patched with heat-welded or self-adhered material, but the more important question is why water is ponding. If the deck has sagged or the drains are too small, patching the seam won’t fix the ponding itself. We inspect the low spots, check the drainage, and patch what’s patchable – then tell you honestly if the roof needs more than a patch. Estimates are free.
No. Most Montclair homes with two layers already exceed what California building code allows for a reroof. Adding a third layer adds weight the framing wasn’t designed for and hides deck damage. We strip down to the original deck, inspect it, replace rotted sections, and then install the new CertainTeed system with proper underlayment. It costs more upfront, but it’s the only way the warranty and the roof actually hold up. Call (877) 731-1384 for an exact quote on your home’s layers.
Yes, and the reason is simple: architectural shingles like Landmark have a thicker mat and more asphalt coverage per square, which means they hold up better under Pomona Valley thermal cycling. Three-tab shingles crack at the tab edges after decades of expansion and contraction. Landmark shingles resist that failure mode significantly better and carry a longer warranty. The cost difference on a typical Montclair ranch is worth it if you plan to stay in the home for more than a few years.
You don’t, until someone climbs up and looks. Flashing failures and shingle failures produce similar symptoms – a stain near a valley, water at a penetration, dampness at the eaves. On a 1958 ranch near the Montclair Plaza area, we tore off two layers of failing CertainTeed XT 25 shingles that had cracked along the tab edges after years of summer heat, only to find the real leak source was a failed valley flashing underneath. We replaced the underlayment, added ridge vents, and installed CertainTeed Landmark shingles in Charcoal Black – stopping a persistent leak at the valley that had puzzled the homeowner for months. The point is, you need eyes on the roof. Call (877) 731-1384 and we’ll show you exactly where water is getting in.
