Why Van Nuys Roofing Co Is Montclair’s Preferred Roof Replacement Company

Montclair homeowners call us because we don’t walk onto a 1963 tract home and pretend the flat rear section doesn’t exist. We’ve opened enough roofs in Montclair to know exactly what a post-WWII stucco house hides: re-coated low-slope seams, decking that baked for thirty summers under old three-tab, and flashing that gave up years ago. Our crews work 91763 and the surrounding foothill communities every week, so we’re not learning the neighborhood from a GPS.

Rick Dominguez runs the company the way a roofer should: inspection first, recommendation second. That means when we quote a Montclair replacement, we walk the whole roof, check the low-pitch sections, and tell you what the scope actually is before you sign anything. If you don’t need a new roof yet, we’ll say so. Repair or replace – we’ll tell you which one actually makes sense.

We work across seven major manufacturers, and that matters more than it sounds. A single-brand shop will steer you toward whatever they stock. We’ll put Montclair GAF service on a steep front slope, spec CertainTeed for a wind-exposed ridgeline, and run a Boral tile option when the home’s original character calls for it. Your roof, your material choice.

Reroofing in Montclair

Reroofing in Montclair means tearing off the old shingle layers down to the decking and building a new system from the felt up, and on Montclair’s mid-century tract homes that first sentence almost always expands once the tear-off starts. The failure on these 1950s-to-1970s single-story stucco houses is rarely just the shingle. It’s the shingle plus a low-slope rear section that was re-coated twice, plus valley flashing that stopped being watertight around the second Bush administration.

What the tear-off uncovers

Curled, brittle tab edges are the visible symptom, but underneath we routinely find decking that’s lost its structural bite where the underlayment baked through. That’s why we write a decking allowance into every Montclair reroof contract, not as a scare tactic but because we’d rather have the line item approved before we find the soft spot than hand you a change order mid-job.

When a Montclair homeowner should reroof now

If your three-tab tabs are cracking at the corners after fifteen-plus Inland Empire summers, the roof is done even if it hasn’t leaked yet. The first real winter storm will find every one of those failures at once. A straight reroof of a standard Montclair footprint, single layer tear-off with new architectural shingles and standard flashing, runs $9,800 to $14,600 here. Add a low-slope section and the number moves.

Flat Roof Replacement in Montclair

Flat roof replacement in Montclair is the piece most homeowners don’t know they need, because the front shingle section looks bad enough that the rear addition or low-slope wing gets overlooked until it’s leaking into the laundry room. These flat-ish sections are everywhere on Montclair’s post-WWII tract stock: rear patios converted to living space, carport rooflines, the low wing off the kitchen that got rolled roofing in 1978 and re-coated again in 2004.

Seams, not shingles

A flat roof fails at the seams and penetrations, not across the surface. On a mid-century Montclair stucco home, the typical flat-roof replacement means tearing off the old rolled material, checking the substrate, re-flashing the edges, and installing a new membrane system with proper positive drainage. That’s a different skillset than steep-slope shingle work, and it’s why we price it separately on the same contract so both sections get done in one mobilization.

What flat replacement costs here

For a typical low-slope rear section on a Montclair single-story, budget $4,200 to $9,000 depending on square footage, number of penetrations, and whether the decking underneath has gone soft. When we bundle flat and shingle replacement on the same job, the shared tear-off and hauling reduces the combined cost versus running them as two projects.

Trusted Brands We Service in Montclair

We install and service GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we stock local inventory for Montclair jobs so the brand you pick doesn’t trigger a three-week waiting period on materials. For the wind exposure Montclair gets along the foothills when Santa Anas push through the passes, we frequently recommend CertainTeed or GAF architectural lines with higher wind ratings, and for flat sections we’ll pair whatever single-ply or modified bitumen system fits the substrate. Seven leading brands, one crew that knows them all. We don’t push one manufacturer because we don’t have to.

Common Roof Replacement Problems We See in Montclair Homes

• UV-baked shingle failure that looks worse on the south slope. Montclair’s summers regularly push past 100°F with little rain, so the dominant wear is drying, curling, and cracking, not rot. By the time tabs are curling, the underlayment underneath has often been cooked for years.
• Failed flat-roof seams on re-coated low-slope sections. Mid-century Montclair homes were often built with low-pitch rears that got rolled roofing, then a coat of silver sealant, then another coat. The seams crack independently of the shingles, and a quote that skips this section undercounts the real job.
• Decking soft at valley penetrations and around old flashing. Hairline cracks let water sit against the plywood at the two or three spots where the roof changes plane. By the time you see a ceiling stain, the decking has had months or years to degrade.
• Santa Ana wind lift on aging shingles with off-spec nailing. When gusts push through the Cajon Pass and hit Montclair’s foothill streets, shingles that were nailed too high or too shallow lift before the shingle itself fails. Wind rating tests assume the installation was correct, and on older homes it usually wasn’t.
