Fast, Reliable Roof Replacement Across Montclair
Roof replacement in Montclair typically runs $9,500 – $18,000 for an average 1,400 – 1,800 sq ft ranch, and most tear-offs take 2 – 4 days once materials are on-site. If you’re in the 91763 ZIP and watching cracked shingles curl on the south slope while the north ridge looks wind-lifted, you’re dealing with the classic Pomona Valley double failure mode. We’ve torn off enough original wood shake and low-slope composition across Montclair to know exactly what’s under there before we quote it. Call (866) 217-3967 for a free estimate, and we’ll walk the roof with you.
Why Moreno Valley Roof Repair Is Montclair’s Preferred Roof Replacement Company
Montclair homeowners call us because we’re brand-agnostic and scope-honest. We don’t push one manufacturer’s program, and we don’t quote a tear-off without inspecting what the existing roof actually looks like. That matters here more than in most places because of what the Pomona Valley does to 1960s tract roofs. Our Roof Replacement team has worked along Kingsley Street, through the blocks off Ramona Avenue, and down toward the Montclair – Pomona line where the housing stock shifts from original ranch builds to 1970s stucco with concrete tile. We know the difference a Santa Ana season makes on a ridge cap, and we price for it up front.
Ruben Ibarra leads our crew, and he’s the one who walks your roof before we ever hand you a number. That inspection-first approach is why our Montclair customers don’t get blindsided by decking rot or wind-lifted flashing after the shingles come off. We also offer Montclair homeowners standalone roof inspections, so you can get a professional assessment before spending a dollar on replacement. If repair makes more sense than a full tear-off, we’ll tell you that instead of upselling you into a roof you don’t need.
Styles & brands we work with
Asphalt Shingle Roof Replacement in Montclair
Asphalt shingle roof replacement in Montclair is our most common full tear-off because most of the city’s ranch-style tract homes were built with wood shake or three-tab composition that’s now 50 – 60 years old. The job here starts with tearing off everything down to the decking, inspecting the sheathing and rafters, replacing any dry-rotted or cracked sections, then laying new underlayment, drip edge, valley metal, and architectural shingles. On Montclair homes we routinely add ice and water shield through valleys and around penetrations, because winter rains funnel through those spots and the original builders often skipped it.
A full asphalt shingle replacement in Montclair runs $8,500 – $13,500 for a typical 1,200 – 1,600 sq ft single-story ranch, depending on shingle grade, decking replacement, and whether we’re dealing with one slope or two on the failure-mode front. Architectural shingles add about $1,200 – $2,500 over three-tab, but most Montclair homeowners choose them for wind resistance and the longer warranty.
Architectural Shingle Upgrades
Most of the Montclair reroofs we quote move from three-tab to architectural shingles, and we typically price GAF Timberline and CertainTeed Landmark. The wind ratings matter here because Santa Ana gusts hit north-facing ridge caps and slopes directly. We set ridge caps with a higher wind-resistant fastening detail than the old roof had, and we don’t reuse old ridge material.
Decking and Sheathing Replacement
On 1950s – 60s tract homes, the south- and west-facing decking is often UV-dead under the old shingles. We quote decking replacement per sheet, written as a line item in the estimate, so you know the cost before the tear-off exposes it. If the original shake was nailed to skip sheathing instead of solid plywood, we convert it to solid decking before the new shingle layer goes down.
New Roof Installation in Montclair
New roof installation in Montclair comes up most often on the newer infill construction along major corridors and on homeowners who bought a 1950s ranch and want to start from a clean deck instead of another overlay. Unlike a straight reroof, a new installation means the framing, decking, underlayment, flashing, and shingle system are all built to current code. That matters in Montclair because the city enforces current California building standards once a roof is fully replaced, and a permit-triggered inspection will catch skipped steps.
New roof installation in Montclair runs $10,500 – $18,000 for most single-family homes, with the spread driven by roof complexity, pitch, and whether we need to bring the decking up to code. We pull permits for every new installation, and the inspection gets scheduled as part of the job, not as an afterthought.
Full Tear-Off and Rebuild
When the decking, fascia, and soffit are all shot, a full tear-off and rebuild is the honest call. On one 1960 tract home near the Montclair – Pomona line, our crew tore off the original wood shake and found the south-facing decking dry-rotted and the north ridge caps wind-lifted from a Santa Ana blow. We replaced the bad sheathing, laid ice and water shield through the valleys and penetrations, set new drip edge and fascia where the old wood had let go, and finished with GAF architectural shingles and a ridge vent. The homeowner got the decking repair priced and signed off in writing before we nailed a single starter strip.
Flat and Low-Slope Roofing
Some Montclair homes, especially the 1970s – 80s stucco builds, have flat or low-slope sections over patios, additions, or carports. These need a different waterproofing approach than pitched shingle slopes. We quote flat roofing as its own scope, with modified bitumen or TPO depending on the existing substrate and the drainage pattern.
Trusted Brands We Service in Montclair
Seven leading brands, one straightforward recommendation. We’re authorized to install and supply materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, which means we can match the shingle to your budget, your wind exposure, and how long you plan to stay in the house. Whether you’re looking at GAF Timberline or Owens Corning Duration, we install both, and we’ll tell you the real difference in wind rating and warranty, not just the price gap. For most Montclair ranchers, we quote GAF architectural shingles as the default and give you CertainTeed and Owens Corning as comparably priced alternates.
Common Roof Replacement Problems We See in Montclair Homes
- UV-baked south and west slopes on 1960s tract homes. Pomona Valley sun sits hard on these slopes all afternoon, and the original three-tab or shake often shatters on removal. We price these slopes with a higher decking-replacement allowance than the north side.
- Santa Ana wind-lifted north ridge caps. The north slope rarely gets the UV death, but it takes the wind. Ridge caps lift, flashing loosens, and if the reroof reuses the old ridge detail, it fails again at the first strong gust. Our detail is different on the north side.
- Dry-rotted fascia and soffit hiding under original wood shake. Decades of leaky valleys and missing drip edge rot the board they’re nailed to. You won’t see it until the old roof comes off, which is why we write fascia and soffit replacement into the estimate as an allowance.
- Failed waterproofing at valleys and penetrations. Original low-slope composition and shake roofs on Montclair ranches often got nothing but felt at the valleys. We lay ice and water shield through every valley and around every pipe boot and chimney before shingle work starts.

FAQs About Roof Replacement in Montclair
Because the Pomona Valley’s UV and wind exposure damages different slopes in different ways, and you can’t see decking rot or wind-lifted ridge flashing through a shingle layer. We price decking, fascia, and sheathing as written per-sheet allowances in the original estimate, so you know what the worst case costs before the tear-off starts. If the rot is lighter than expected, you pay less. Call (866) 217-3967 and we’ll show you exactly how the allowance works on your roof.
Yes, when permits are pulled for a full replacement, the city enforces current California building code, and a permit-triggered inspection will require proper decking and roofing details. That’s a good thing. We pull permits on every full replacement, and we build the code compliance into the quote up front rather than discovering it mid-job.
We bid them separately. The south and west slopes get a higher decking allowance because Pomona Valley UV has typically baked the shingles and underlayment brittle, while the north side gets a stronger ridge-cap fastening detail because Santa Ana winds have lifted the old caps. One roof, two profiles, one honest estimate. That’s the only way to price a Montclair ranch without surprises.
Go line by line. Ask what each contractor is charging per sheet of decking replacement, what underlayment they’re using in valleys, whether fascia and soffit are included or extra, and what the wind rating is on the shingle they quoted. We hand you an itemized estimate so you can compare exact scopes, not just bottom lines. Call (866) 217-3967 for a free quote you can actually take apart.
We install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and for Montclair’s Santa Ana exposure we steer most homeowners toward architectural shingles rated for 110 – 130 mph wind uplift. We’ll show you the actual wind-rating documentation for the brands you’re comparing, so the choice is based on your roof’s exposure, not a slogan.
