Roof Replacement in Montclair, CA: What It Costs and Why Local Experience Matters
A full Roof Replacement in Montclair typically runs $11,000 to $26,000 for a standard single-story tract home, with flat roof sections over patios and additions adding $1,800 to $5,000 depending on square footage and decking condition. Most Montclair jobs take 3 to 7 working days once materials land. What separates Montclair from nearby cities is what happens after the shingles come off. The 1950s and 1960s ranch homes that dominate this city were built with 1x wood sheathing that has been baking under Inland Empire sun for six decades, and a significant share of re-roofs here turn into sheathing replacement jobs once the old layers are stripped.
We work throughout the 91763 zip code, from the tracts along Central Avenue up to the neighborhoods near the Montclair Plaza. If you’re researching roof replacement in Montclair, call (833) 589-7971 and we’ll give you a straight answer on what your specific roof needs.
Why Montclair Homeowners Call Hollywood Roofing Co
Roland Vega has built our Montclair reputation on showing up, looking at the roof, and telling homeowners what’s actually going on up there. No scare tactics. No one-brand push. We install seven major roofing brands, which means the recommendation you get is the one that fits your house and your budget.
Montclair’s housing stock is specific. Single-story stucco ranches. Low-slope and shallow-pitch roofs. Original wood sheathing. Attics with minimal or no ventilation. The roofer who understands how those factors interact is the one who gives you an accurate quote the first time. Our crew has stripped enough roofs in Montclair to know what we’ll likely find before we start, so your estimate accounts for reality instead of surprising you with change orders.
We hold ourselves to a simple standard: the same team that inspects your roof is the team that replaces it. No handoff to a subcontractor you’ve never met. From the first inspection to the final nail, you’re dealing with one company.
Styles & brands we work with
Flat Roof Replacement in Montclair
Flat Roof Replacement in Montclair is one of the most common jobs we do, because so many of the post-war ranches here have low-slope sections over patios, enclosed porches, and additions. These are not true commercial flat roofs. They’re shallow-pitch residential sections, often rolled roofing over old plywood or 1x decking, and they fail in predictable ways: ponding water during winter rains, rusted flashing along the seams, and UV-baked surface material that is cracked and brittle by August.
A flat roof replacement on a Montclair home typically costs $1,800 to $5,000 for a standard patio or addition section. The price depends on whether the underlying decking is sound and whether drainage can be corrected.
Drainage Correction During Flat Roof Replacement
Low-slope sections collect water when the original drainage design was marginal and decades of settling have made it worse. We can add tapered insulation or a sloped underlayment system to get water moving toward the scupper or edge. If you’ve spotted standing water that lingers after rain, that section needs more than new membrane. It needs slope correction or the next replacement comes sooner than it should.
Overlay vs. Tear-Off on Patio Roofs
Some Montclair homeowners ask if we can just overlay a new membrane on top of the old one. Sometimes yes, but the 1x decking beneath matters more here than the surface. If the boards have cupped or the seams have opened, an overlay hides the problem instead of fixing it. We’ll inspect the decking before recommending the path.
Roof Installation in Montclair
Roof Installation in Montclair almost always means a full tear-off and replacement on a home that is old enough to have original decking. For most of the city’s 60-year-old ranches, we’re not the first crew on this roof. We’re likely the second or third. That’s fine, but it means the condition of the sheathing determines how the job proceeds. In fact, we scope roof installation as two phases: the visible roofing system and what lies beneath it.
A standard architectural shingle roof installation in Montclair runs $9,000 to $18,000 on most single-story homes. Larger homes or those with multiple roof planes push toward $25,000 or more.
New Construction and Full Tear-Offs
For new construction or a complete re-roof, we install the full system: underlayment, high-temp ice and water shield in valleys and eaves, shingles, ridge vent, flashing, and drip edge. Montclair’s summer roof-surface temperatures above 150°F mean underlayment selection matters more here than in coastal cities.
The Decking Reality on Montclair Tracts
When we strip shingles on a 1950s or 1960s ranch here, the 1x decking underneath is often cupped, split, or brittle. Inland heat draws moisture out of the wood over decades, and once the boards lose their structural grip on fasteners, new shingles will not hold properly. Plan for decking replacement as a real possibility. We’ll price it into your estimate if inspection shows it is likely.
Trusted Brands We Service in Montclair
We install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Seven brands, each with different strengths at different price points. GAF and CertainTeed give you top-tier warranty backing and premium architectural profiles. Tamko and IKO are strong value picks for budget-conscious Montclair homeowners who still want a 30-year roof.
Because we’re brand-agnostic, you get an honest recommendation matched to your home. We keep relationships with local distributors across the Inland Empire, so material availability in Montclair is rarely a delay point. You choose the brand, not the other way around.
Common Roof Replacement Problems We See in Montclair Homes
- Cupped 1x decking. Stripping old shingles reveals dried, cupped boards that no longer hold fasteners. This forces a decking replacement before new underlayment can go down, and it’s the single biggest surprise item on Montclair re-roofs.
- Low-slope ponding. Shallow-pitch sections over patios and additions collect water during intense winter rains. That water rusts flashing, rots fascia, and shortens the life of any roofing material above it.
- UV-driven granule loss and thermal cracking. Unventilated attics push roof-surface temperatures past 150°F in summer, baking architectural shingles and aging them years ahead of schedule. Granules in your gutters are the early warning sign.
- Santa Ana wind damage on older fasteners. Ridge caps and shingles installed decades ago have lost their grip. The first strong Santa Ana event of the season rattles things loose, especially on the shallow-pitch roofs that dominate Montclair’s oldest tracts.

AfterPricing for Roof Replacement in Montclair, CA
Here are the numbers we quote most often in Montclair:
- Standard architectural shingle re-roof, single-story ranch: $11,000 to $18,000
- Larger or multi-plane homes: $18,000 to $26,000
- Sheathing replacement (partial or full): $1,500 to $4,500 depending on how much decking has failed
- Flat roof section over patio or addition: $1,800 to $5,000
- Ridge vent or ventilation upgrade: $400 to $1,200
What moves the number most in Montclair is decking condition. Homes built in the 1950s and 1960s with original sheathing will likely need some decking work. Homes that have been re-roofed once or twice may already have newer plywood. The honest approach is to inspect first, then quote. Call (833) 589-7971 to schedule a roof inspection and we’ll give you a written, line-item estimate that accounts for Montclair’s specific conditions.
What a Montclair Roof Replacement Often Includes (That Other Quotes Miss)
Montclair sits squarely in the hot, dry thermal belt along the 10 freeway. Summer roof-surface temperatures routinely exceed 150°F, and the city’s housing stock is overwhelmingly modest post-war and mid-century single-story tract homes. That combination means a Montclair roof replacement frequently includes three things a generic quote will not cover: decking replacement, drainage correction on low-slope sections, and attic ventilation improvement.
On a 1950s ranch near the 10 freeway in Montclair, our crew stripped the original asphalt shingles and found the 1x decking cupped and split from decades of inland heat. We replaced the damaged sheathing, laid a high-temp ice and water shield in the valleys, and installed GAF architectural shingles with a six-nail pattern rated to 130 mph. Then we added a ridge vent to finally give the attic some relief. That’s the difference between a quote that looks cheap and a roof that actually lasts in this climate.
We scope all of this before you sign. The estimate reflects what we expect to find based on the home’s age, the neighborhood, and what we’ve seen on neighboring Montclair homes. You’re not paying for surprises after we start.

FAQs About Roof Replacement in Montclair
No, but it affects installation details. Most architectural asphalt shingles are rated for slopes as low as 2:12, and Montclair’s shallow-pitch ranches fall within that range. The critical factors are underlayment and fastening. We use high-temp underlayment and a six-nail pattern on low-slope sections over original decking. Very low-pitch sections, especially over patios, may perform better with a flat roofing system instead of shingles. We’ll tell you which applies to your roof. Call (833) 589-7971 for an exact assessment.
Montclair is an incorporated city with its own building department, so most roof replacements require a city permit, not a county one. The permit covers tear-off, decking replacement if needed, and the new roofing system. We pull the permit as part of the job and schedule the required inspection. Our work passes Montclair inspections because we build to code instead of cutting corners. Get in touch at (833) 589-7971 and we’ll walk you through the permit timeline for your street.
Most Montclair roof replacements fall between $11,000 and $26,000, with flat roof sections adding $1,800 to $5,000. The biggest variable is whether the original 1x decking needs replacement, which runs $1,500 to $4,500 depending on how many boards have failed. Homes that have already had one full re-roof tend to be less expensive than those getting their first replacement. For a precise number, call (833) 589-7971 and we’ll schedule an inspection.
Because Montclair’s original 1x sheathing has been cooking under 150°F+ roof-surface temperatures for 60 years. The wood dries, cups, and splits. When moisture does get in during winter rains or from condensation, the damaged boards rot faster than sound wood would. Add minimal attic ventilation to the equation and the decking never gets a chance to dry. We scope for this before quoting, so it rarely catches Montclair homeowners off guard.
A ridge vent combined with intake at the eaves is the most effective system for Montclair’s shallow-pitch ranches, assuming the attic has a clear path for air to move. Homes with very low slopes or blocked soffits may need an alternative like box vents or a powered vent. Proper ventilation drops attic temperatures and extends shingle life in this climate. Call (833) 589-7971 and we’ll check your existing ventilation during the estimate.
