Why Bedrock Roof Repair Is Montclair’s Preferred Roof Replacement Company
We work the Montclair neighborhoods along Mission Boulevard, Monte Vista Avenue, and the tracts west of Central Avenue often enough to know what roofs here actually do over time. Homeowners in Montclair call us because our name commits to a sequence: inspect first, repair if that’s honest, replace when that’s the only move that makes sense. Alan Cofield runs Bedrock Roof Repair with that repair-first discipline, and it’s why a lot of Montclair customers start with a leak and end up knowing exactly what they need, even if it’s less than they expected.
We’re not a referral desk. The same crew that walks your roof in Montclair is the crew that tears it off and installs the new system, from first nail to final inspection. That continuity matters on Montclair’s 1960s ranch roofs, where what you find under the old shingles changes the job. We’ve pulled original wood shake off shallow-pitch sections more times than we can count. When a roof opens up and the decking’s rotted along a scupper line, you don’t want a different contractor suddenly making decisions. You want the person who saw it first. That’s us.
Bedrock Roof Repair installs products from seven leading manufacturers including GAF, CertainTeed, and Owens Corning, so a material recommendation comes from your roof’s actual condition and your budget, not from a supply deal we’re trying to protect. Call (833) 589-7850 for a free estimate on roof replacement.
Styles & brands we work with
Roof Replacement Contractor in Montclair
A roof replacement contractor in Montclair faces a specific set of conditions: 1950s – 1970s single-story tract homes with low-slope or shallow-pitch sections, original wood shake or asphalt shingle nearing end of life, and wind-driven debris coming down off the San Gabriel foothills. The job here isn’t just swapping shingles. It’s evaluating drainage, decking condition, and whether the existing nailing pattern can hold against Santa Ana wind uplift. A full replacement in Montclair on a typical 1,200 – 1,600 sq ft ranch runs $9,800 – $14,600 when we’re working over a standard asphalt shingle base. If we find rotted decking, failed underlayment, or the need to reframe drainage, the number moves up from there, and we show you exactly why.
What the Permit Step Actually Covers
Montclair sits under California Building Code Title 24 requirements. A compliant roof replacement includes a building permit, an inspection at the nailing stage, and a final sign-off. Wind uplift ratings matter here because Montclair’s location below the foothills puts roofs in a higher exposure category than flat inland cities farther east. We nail to the manufacturer’s high-wind pattern and document it. That documentation is what your insurance carrier wants to see if a claim comes later.
Why Decking Replacement Changes the Bid
On a low-pitch 1960s tract roof, water sits longer than it should when scuppers clog with foothill leaf litter. That ponding rots decking along the drainage path. If we find it during tear-off, California code requires replacement of damaged decking before new underlayment goes down. It’s not an upsell. It’s the difference between a roof that lasts twenty years and one that fails in two seasons. We show you the rotted boards before they leave your property.
Asphalt Shingle Roof Replacement in Montclair
Asphalt shingle roof replacement in Montclair is the most common full-system job we do here, and for good reason. The city’s housing stock, largely 1950s – 1970s tract homes, was built with a first-generation shingle that’s now decades past its service life. Inland Pomona Valley heat cycles the shingles through thermal expansion every summer day, and Santa Ana winds finish what UV started. A typical asphalt shingle replacement on a Montclair single-story home runs $9,800 – $14,600 using architectural shingles with a high-wind rating. That includes tear-off, disposal, underlayment, flashing, and the permit.
Ice and Water Shield in the Valleys
Montclair’s shallow-pitch roofs hold water in the valleys longer than steep roofs anywhere else. That’s why we install ice and water shield along low-slope valleys, scuppers, and penetrations as standard practice here, whether code strictly requires it on every section or not. It’s cheap insurance against the exact failure mode Montclair roofs are known for: slow drainage, ponding, and underlayment saturation.
The Architectural Shingle Difference
We recommend architectural shingles like GAF Timberline or CertainTeed Landmark on almost every Montclair GAF service we provide. They carry a higher wind rating than three-tab shingles and handle UV cycling better over a twenty-plus-year service life. On a 1960s ranch with a shallow pitch, a dimensional shingle also sheds debris better because the profile creates less flat surface for foothill grit to sit on. The upgrade cost is modest, usually $1,200 – $2,400 on a standard roof, and it’s the difference between a fifteen-year roof and one that still looks right at twenty.
Trusted Brands We Service in Montclair
Bedrock Roof Repair installs products from seven major roofing manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. We’re not tied to any one of them. When we recommend a GAF Timberline architectural shingle for a Montclair ranch, it’s because that product’s wind rating and drainage profile suit the roof, not because a supplier pushed it. For flat or low-slope built-up sections on older Montclair homes, we spec materials from the same seven-brand lineup based on what the roof actually needs. Because we carry relationships with all seven, material lead times stay short for Montclair customers. You’re not waiting three weeks because one manufacturer’s distribution is backed up. We’ll tell you what your roof actually needs: roof replacement, repair, or nothing yet.

AfterCommon Roof Replacement Problems We See in Montclair Homes
- Clogged scuppers on low-pitch 1960s roofs. Foothill leaf litter and grit wash down into shallow drainage paths every winter. Water ponds behind the clog, rots decking within a season, and the leak shows up on the ceiling months later.
- Santa Ana wind lifting aging shingles. Original nailing patterns on 1950s – 1970s tract homes weren’t designed for the uplift Montclair gets when winds channel down from the foothills. Once shingles start lifting, water intrusion at the nail line accelerates.
- UV-cracked flat built-up roofing. Inland heat cycles flat roofs hard in Montclair. The surface cracks, water finds the seams, and flashing at penetrations fails. A full replacement here usually means addressing drainage, not just recovering the membrane.
- Original wood shake under old shingles. We find shake roofs that were shingled over decades ago and never properly flashed. The shake dries out underneath, holds moisture, and rots the decking. When we open these roofs in Montclair, the scope often grows, and we document every layer with photos so you’re not taking our word for it.
Pricing for Roof Replacement in Montclair, CA
A full tear-off and replacement on a standard Montclair single-story ranch runs $9,800 – $14,600 for asphalt shingle systems over sound decking. Add $1,200 – $2,400 if you upgrade from three-tab to architectural shingles. Roof decking replacement in Montclair typically adds $45 – $75 per 4×8 sheet, depending on how much of the old decking is rotted along drainage paths. Flat and low-slope built-up roofing on patios and additions runs higher per square because of the membrane and taper work involved. New construction or full re-framing is a different animal entirely, and we’ll walk you through those numbers on site. One honest recommendation, not three bids with different scopes.

FAQs About Roof Replacement in Montclair
In Montclair, a new asphalt shingle roof typically needs a minimum wind rating of 110 mph, and we install to the manufacturer’s high-wind nailing pattern to exceed that standard. Because Montclair sits below the San Gabriel foothills where Santa Ana winds channel downslope, we recommend architectural shingles rated for 130 mph where the roof’s exposure and pitch allow it. The specific rating your roof needs depends on its height, pitch, and exact location in Montclair. We document the nailing pattern and product rating in the permit file so your insurance carrier can verify compliance if a wind claim ever comes up. Call (833) 589-7850 and we’ll assess your roof’s wind exposure on site.
A low-slope roof in Montclair needs replacement when the drainage system has failed, decking is rotted, or the existing covering is at the end of its service life, which for original 1960s built-up roofing is usually somewhere between 20 and 30 years. The telltale signs out here are ponding water that doesn’t drain within 48 hours after rain, soft spots you can feel underfoot, and leaks at the scupper lines where foothill debris has clogged the drainage path. If the drainage is intact and the decking is sound, a targeted repair is often the honest answer. Bedrock Roof Repair evaluates repair before replacement on every job, it’s in the name. Call (833) 589-7850 for a straight assessment.
A compliant quote in Montclair includes a building permit, a nailing inspection, a final city sign-off, and documentation of the wind rating and nailing pattern, and those items are the first things a cheap bid skips. It also includes water and ice shield along the low-slope valleys and scuppers, which is not always code-required on every section but is standard practice on Montclair’s ponding-prone ranch roofs. Cheap bids also tend to assume the decking is sound and never mention what happens when the old roof comes off and the real condition is exposed. We itemize all of it. Same team from inspection to final nail, no handoffs, no surprises.
Documented permit compliance gives you a record trail: the permit, the nailing inspection, the final approval, and the product specs. If a Santa Ana wind event or a storm damages your new roof, your carrier will ask what rating the roof was installed to and whether it passed inspection. An unpermitted reroof, or one without documentation, can reduce your claim payout or slow it down while your carrier investigates. A permitted, documented replacement in Montclair means your insurance has a verified record to process from. We handle the permit, schedule the inspections, and walk the job through to final sign-off. Call (833) 589-7850 if you’re weighing a roof against an insurance decision.
A roofing square is 100 square feet of roof area, and most Montclair single-story tract homes run between 12 and 18 squares depending on the actual roof footprint, pitch, and overhangs. When you compare bids, ask each contractor to state the square footage they’re quoting and the price per square, including tear-off, disposal, underlayment, flashing, and permit. A bid that’s $2,000 cheaper but quotes four fewer squares isn’t cheaper, you’re paying the difference in change orders later. In Montclair, where an original 1960s roof often needs more decking work than expected once it’s opened up, knowing your square count upfront keeps the conversation honest. Call (833) 589-7850 and we’ll measure your roof and show you the square math in the quote.
If you’re looking at a roof replacement in Montclair, call (833) 589-7850 to schedule a free estimate. We’ll walk the roof, open the conversation with what’s actually there, and give you a written, line-item quote. No pressure. No handoffs. Repair when possible, replace when necessary.
