Fast, Reliable Roof Replacement Across Montclair
A full roof replacement in Montclair typically runs $11,000 to $24,000 depending on square footage, decking condition, and material choice. Most tear-offs in the 91763 zip code take 2 to 5 working days once the old roof comes off. If you’re in an older tract off Holt or Ramona, plan for re-sheeting costs before anyone nails down a single shingle. Call (866) 942-4187 and we’ll give you a straight answer about what your roof actually needs.
We work in Montclair weekly. Our crews know the post-war tract layouts, the way the afternoon heat sits on a west-facing slope, and what’s hiding under wood-shake roofs that have been up there since Nixon was in office. That local familiarity changes how we price, how we schedule, and what we tell you about the job before we start.
Why Orange County Roofing Co Is Montclair’s Preferred Roof Replacement Company
We’re the company Montclair homeowners call when they want a roof quote that doesn’t fall apart halfway through the job. Kurt Hensley built Orange County Roofing Co on a simple idea: stock the full range of roofing products, recommend honestly, and document every step. That’s why we carry seven major shingle brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – instead of one. When we tell you an Owens Corning architectural shingle fits your Montclair roof better than an IKO product, it’s because it actually does, not because it’s the only thing we sell.
Montclair homeowners call us about two things: aging wood-shake roofs that need a full tear-off, and asphalt shingle replacements on 1970s and 1980s tract homes that have finally reached the end of their service life. Both jobs have one thing in common here – what’s under the roof matters as much as what goes on top. We write our bids for what the roof actually needs, not what makes the number look small.
Our Roof Replacement team handles inspection, repair, and full replacement under one roof. You don’t need to vet three separate companies at different stages of your roof’s life. One call covers it, from a single damaged shingle to a full tear-off with new decking and architectural shingles.
Styles & brands we work with
Asphalt Shingle Roof Replacement in Montclair
Asphalt Shingle Roof Replacement in Montclair is the most common job we do, and it usually costs $9,500 to $16,000 on a typical 1,200 to 1,800 square foot single-story tract home. The old shingles come off, we inspect and repair the decking, lay new underlayment, and install architectural shingles nailed to the manufacturer’s wind-rating spec. For most of these homes – built between the 1950s and 1980s – the original roof has been through 30-plus Inland Empire summers, and the shingles are cracking from UV exposure, not rain.
Architectural Shingle Upgrades
Most Montclair homeowners upgrade from three-tab to architectural shingles when they replace. The cost difference is modest – architectural runs $2 to $4 more per square foot installed – but you get a thicker laminate shingle that carries a higher wind rating and handles the sun better. In the older tracts off Ramona Avenue, we rarely see anyone go back to three-tab once they see the price spread.
Repairing Decking Before Nailing
A shingle replacement in Montclair frequently turns into a decking repair job. The original roofs on these tract homes were built fast and cheap, and 40 years of heat cycling leaves plywood brittle or rotted where flashings failed. We photograph every damaged section we find and itemize the repair in your quote – no surprise change orders.
New Roof Installation in Montclair
New Roof Installation in Montclair applies to two situations: a full tear-off where everything down to the rafters gets replaced, or new construction on a lot in the 91763 area. For a full tear-off with new decking, underlayment, and architectural shingles, expect $14,000 to $24,000 on a typical single-story home. New construction pricing depends on structure size and pitch, but a standard new build roof usually falls in the same range once framing and decking are factored in.
Full Tear-Off and Re-Sheet
When an old wood-shake roof comes off in Montclair, we treat it as a re-sheet project from the first bid. The original homes off Holt and Ramona were often built with skip sheathing – spaced boards with gaps – and no underlayment. You can’t nail modern shingles to that. We install solid plywood or OSB decking, then build the roof assembly up from there.
New Construction Roofing
New builds in Montclair need a roof that meets current California Title 24 energy standards and local wind-rating requirements. We work with the framing crew to make sure the decking is nailed properly before we ever touch a shingle. Then we install the system – underlayment, drip edge, valley flashing, ridge vent – and document it all for inspection.
Trusted Brands We Service in Montclair
We install Owens Corning, IKO, Atlas, and Tamko – along with GAF, CertainTeed, and Boral – so we can recommend the right material for your Montclair roof without a brand bias. Each manufacturer has different warranty tiers, wind ratings, and price points. We stock common colorways and accessories locally, which means we aren’t waiting on a distributor in Riverside when your job is scheduled. The right material for your roof, backed by the manufacturer’s own warranty.
Common Roof Replacement Problems We See in Montclair Homes
- Skip sheathing under old wood-shake. In the older tracts off Holt and Ramona, original roofs were laid over spaced boards with no underlayment. The decking itself, not the shingles, often drives the final bid and schedule.
- Rotted decking at flashings. Decades of Inland Empire heat and the occasional winter storm wear out valley and pipe flashings. Water seeps in, rots the plywood around penetrations, and you don’t know until the old roof comes off.
- Shingles nailed outside the manufacturer’s pattern. A shingle that isn’t nailed to spec never earns its wind rating. First big storm of the season, edges peel back, and the roof fails the one time you actually need it to hold.
- Flat patio additions shingled like the main roof. Many Montclair tract homes have flat or low-slope patio additions that need a true membrane system – not shingles – to handle heat and UV cycling. Shingling a low-slope addition is a leak waiting to happen.

FAQs About Roof Replacement in Montclair
The original wood-shake roofs in Montclair’s older tracts were frequently laid over skip sheathing with no underlayment beneath them. That means the tear-off exposes a deck that cannot hold modern shingles without re-sheeting. Solid plywood or OSB decking, new underlayment, and the labor to install them add $2.50 to $5 per square foot on top of the shingle price. A bid that doesn’t account for this is guessing, and you’ll find out when the change order arrives. Call (866) 942-4187 and we’ll inspect what’s under your old roof before we quote.
A Montclair roof replacement should meet at least a 110 mph wind rating, which is standard for the Inland Empire’s exposure and what most manufacturers specify for architectural shingles installed with six nails per shingle. The rating only holds if the shingles are nailed exactly to the manufacturer’s pattern – not closer, not farther apart, not at the wrong angle. We nail to spec and document it. Cheap crews that nail outside the pattern void the rating, and the roof fails in the first winter storm.
Yes. A documented, inspection-ready roof assembly with photographed decking repairs and itemized material specs gives you the paper trail your insurance company wants when premium reviews or wind claims come up. Insurers in California increasingly ask whether the roof meets current wind-rating codes. If the answer is “we don’t know,” you’re in a weaker position. We build the documentation into every job.
A compliant quote includes decking repair, new underlayment, drip edge, valley and penetration flashing, ridge vent, and shingles nailed to the manufacturer’s wind-rating pattern – with each line item spelled out. A low bid that prices shingles only collapses once the old wood-shake comes off and the skip sheathing and rotted decking underneath are exposed. That’s the number one reason Montclair roof jobs go over budget.
Flat and low-slope patio additions need a true membrane system – TPO, modified bitumen, or a peel-and-stick product – with proper flashing at the transition to the main roof. We don’t shingle over a low-slope surface; that’s a leak waiting to happen in the Montclair heat-UV cycle. We price the patio addition separately and build it as a distinct assembly.
