Fast, Reliable Roof Replacement Across Montclair
A full roof replacement in Montclair typically runs $9,800 to $22,000, depending on roof size, pitch, tear-off work, and the shingle spec you choose. That range covers most single-story tract homes built between 1950 and 1980 across the 91763 ZIP. Asphalt architectural shingles are the most common material we install here, and most Montclair jobs wrap up in two to five days. What matters more than speed is that the work actually passes inspection and holds up against the Santa Ana winds that hit the southern part of town. Baycrest Roofing is led by Nolan Cafferty, and we inspect first, recommend second. Call (866) 412-5697 to schedule a free estimate in Montclair.
Why Baycrest Roofing Is Montclair’s Preferred Roof Replacement Company
We carry seven major shingle brands: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters in Montclair because not every roof here needs the same wind rating, and not every homeowner wants to pay for a premium product when a value-tier shingle does the job honestly. We match the material to your roof, not your roof to our inventory.
Our process starts with an inspection. Nolan Cafferty built the company around a simple rule: no quote before we walk the roof. In Montclair we look for wind-related failure patterns first, cracking along the ridge line specifically, then check decking, flashing, and underlayment. If a repair will fix the problem, we say so. If replacement is necessary, we show you exactly why with photos from your own roof.
Montclair homeowners get the same crews we send across the Pomona Valley. We know the 1960s tract layouts, the low-pitch geometry, and the wind patterns that stress southern-facing ridge caps. Our Roof Replacement team has completed dozens of jobs in 91763, and the typical feedback we hear is that the crew showed up when promised and left the yard clean. We hold ourselves to that standard on every job.
Styles & brands we work with
Flat Roof Replacement in Montclair
Flat Roof Replacement in Montclair means removing an existing membrane or built-up roof and installing a new low-slope system, usually modified bitumen or a single-ply membrane like TPO or PVC. Many Montclair homes have flat or very low-pitch sections over carports, patio extensions, or room additions, even when the main house is a pitched shingle roof. These flat areas fail faster in the inland heat because the sun beats directly on the surface all day. A flat roof replacement on a typical Montclair carport or addition runs $4,200 to $9,500 depending on square footage and the membrane selected.
Low-Slope Systems
We install modified bitumen and TPO systems on Montclair homes. Modified bitumen handles foot traffic well and costs less up front. TPO reflects heat, which keeps the house cooler through inland summer days. Both need proper slope-to-drain details and sealed penetrations.
Flat Roof Failure Points
Flat roofs in Montclair fail most often at the seams and at flashing around vent pipes and HVAC curbs. The Pomona Valley heat expands and contracts membranes, and after enough cycles the seams split. We inspect those seam areas specifically before recommending replacement.
Roof Installation in Montclair
Roof Installation in Montclair covers new roof construction and full teardown-and-replace scope on existing homes. New construction work runs $11,000 to $24,000 for a typical single-story build, depending on roof size, pitch, and shingle grade. Full tear-off and replacement on an existing 1960s tract home Lands between $10,500 and $19,800. The difference comes down to decking condition, how many layers are coming off, and whether we need to reinforce the existing framing.
Decking and Underlayment
On older Montclair homes, the roof deck often has water damage around the valleys and eaves. We replace damaged sections before laying new underlayment. We also spec synthetic underlayment rather than felt on replacement jobs because it holds up better to the temperature swings in the Pomona Valley.
New Construction Roofing
We roof new builds in Montclair and surrounding areas. The process includes decking installation where the framing is ready, underlayment, venting, and shingle or membrane installation. Builders and homeowners both get a documented compliance package at the end of the project.
Trusted Brands We Service in Montclair
We stock materials from brands that perform well in southern California inland conditions. Owens Corning Duration and CertainTeed Landmark are two of the most common architectural shingles we install in Montclair because they carry wind ratings that satisfy local requirements. For homeowners watching the budget, Atlas and Tamko both offer architectural shingles with 110-mph wind ratings at a lower material cost than premium-tier lines. Boral’s stone-coated steel brings a heavier product for Montclair homeowners who want maximum wind and impact resistance. Because we work across seven manufacturers, we can pull materials quickly for Montclair jobs without waiting on a single distributor.

AfterCommon Roof Replacement Problems We See in Montclair Homes
- Wind-uplift cracking along ridge lines. Southern Montclair neighborhoods catch the afternoon Santa Ana winds as they funnel through the Pomona Valley. On 1960s tract homes, the original ridge caps crack and lift, and the shingles along the peak start to split.
- Thermal cycling breakdown. Inland heat builds up in the attic and cooks the shingle from the underside while the sun bakes it from above. After 20 to 25 summers, the asphalt becomes brittle and the granules wash off easily.
- Skipped ice and water shield at valleys. Cheap quotes often leave out ice and water shield in the valleys and at the eaves. Montclair’s occasional heavy downpours find those gaps and run water under the new shingles, and the inspection fails.
- Failed drip edge. Older homes around Montclair were often built without drip edge, or with corroded metal that no longer directs water into the gutters. A compliant replacement includes new drip edge at all eaves and rakes.
Pricing for Roof Replacement in Montclair, CA
Most Montclair roof replacements land between $9,800 and $22,000. A smaller 1,100 square foot roof with architectural shingles and a single-layer tear-off usually comes in around $10,500 to $13,500. A larger roof with steep pitch, two layers to remove, and premium shingles like CertainTeed Landmark Pro or GAF Timberline HDZ can push toward $19,000 to $22,000. Flat roof sections add cost based on membrane type. The variables are roof size, pitch, decking condition, shingle grade, and whether the existing roof is one layer or two. We give you a written line-item quote before any work starts, and that number does not move unless we find hidden decking damage, which we document with photos before proceeding.

FAQs About Roof Replacement in Montclair
Montclair falls under California’s wind exposure requirements for the inland valleys, and most shingle manufacturers specify a 110-mph wind rating for this area. High-wind zones in the southern part of Montclair may warrant a 130-mph rated shingle when the roof has exposure to open valley wind patterns like the Santa Ana corridors that follow through from Ontario. We spec the shingle based on the roof’s exposure, not the neighborhood average. Call (866) 412-5697 for a free assessment of your roof’s wind-load requirements.
Yes, the City of Montclair requires a building permit for roof replacement, and a final inspection must pass before the job is closed. The inspection covers nailing pattern, underlayment, flashing, and ventilation. We pull the permit as part of the job and schedule the inspection, and we stay on site until it passes. A roof without a passed inspection can become a problem when you sell the house or file an insurance claim.
A documented, code-compliant roof replacement with a wind-rated shingle and high-wind ridge cap often qualifies for a homeowners insurance premium discount, and it makes any future wind-damage claim easier to process. We provide a compliance report at the end of every Montclair job: permit number, inspection result, shingle spec, nailing pattern, and photos of the completed installation. You submit that to your carrier. If the insurer knows the roof meets current wind-load requirements, they see less exposure on the property. Call (866) 412-5697 to discuss what documentation you’ll receive before you sign anything.
A compliant Montclair quote should include ice and water shield at valleys and eaves, a six-nail nailing pattern for architectural shingles, a high-wind ridge cap, new drip edge, and a permit line item with inspection fees. Cheap quotes often leave out the ice and water shield and drip edge, then use a four-nail pattern that fails the city’s wind-load inspection. If the price looks too good, ask what’s missing. The free estimate we give you is line-item detailed so you can compare honestly. Call (866) 412-5697 for a written quote.
Southern Montclair’s 1960s tract homes have low-pitch roofs and original ridge caps that were never rated for the Santa Ana wind patterns that funnel through the Pomona Valley. The afternoon winds hit the southern-facing slopes and lift the shingles along the ridge, cracking the caps and loosening the seal strips. Over decades, that repeated cycling weakens the roof in a specific pattern, and we see it on nearly every original roof in that part of the 91763 ZIP. The fix is a wind-rated ridge cap and a six-nail pattern on the new shingles, which we include as standard on Montclair replacements.
