Key Takeaways
- Full roof replacement in Montclair typically costs $8,500 to $16,500, with decking replacement adding $2,000 to $5,000 when original skip sheathing is compromised.
- Montclair’s 1950s-1970s tract homes and mobile-home parks frequently have original tar-and-gravel roofs or low-pitch systems, not steep shingle roofs.
- We inspect first and open the roof before final pricing. Any decking or framing repair is priced as a written change order before work proceeds.
- Tilecraft installs products from seven manufacturers, including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so the material matches the roof, not our inventory.
- Fall and early spring are the best seasons for roof work in Montclair, before the first heavy winter rains expose failures in dried-out membranes.
Styles & brands we work with






Why Tilecraft Roofing Is Montclair’s Preferred Roof Replacement Company
Montclair homeowners call us because we tell them what’s actually on their roof before they spend a dollar. We’re not tied to one brand or one roof type. We install asphalt shingle, flat membrane, and mobile-home roofing systems, and we carry material lines from seven manufacturers so the recommendation fits the house. That matters in a city where a 1962 tract home with a tar-and-gravel roof and a manufactured home on a permanent foundation need very different solutions.
Our reputation in Montclair comes from doing the unglamorous work correctly: pulling permits through the city, opening roofs to check decking before quoting, and writing change orders that homeowners can read and understand. Ruben Castellano runs every Montclair job the same way: look first, quote second, build third. We serve the entire 91763 ZIP code, from the neighborhoods around Montclair Place to the residential streets east of Central Avenue. Call (833) 467-4846 to schedule yours.
Reroofing in Montclair
Reroofing in Montclair means tearing off the existing roof surface down to the decking and installing a new system, and on the city’s mid-century tract homes, that often means discovering what’s underneath. We regularly open roofs on homes built between 1955 and 1975 and find original 1×6 skip sheathing that’s split, delaminated, or so dried out it won’t hold a fastener. When that happens, we stop, write a change order for the decking replacement, and get your approval in writing before we proceed. The reroof itself typically runs $8,500 to $13,000 for a standard single-story Montclair home, with decking replacement adding $2,000 to $5,000 depending on how many sheets have failed.
Decking Inspection Before the Tear-Off
We open a section of the roof and inspect the sheathing before we finalize your quote. On a 1958 tract home near the Montclair Plaza, our crew tore off three layers of tar-and-gravel and found the original 1×6 skip sheathing split and delaminating under the roof cement. We replaced 22 sheets of 7/16 OSB, installed GAF Tiger Paw underlayment, and finished with GAF Timberline HDZ architectural shingles in Charcoal, adding a ridge vent and new drip edge along the fascia. The homeowner got a written change order for the decking before we nailed a single shingle, and the new roof has held through two winters without a leak.
Skip Sheathing and Fastener Failure
Original skip sheathing on Montclair homes fails when re-nailed because the gaps between boards leave fasteners unsupported. The result is nail pops, wind uplift at eaves, and shingles that never seat properly. We check for this on every Montclair reroof before we price the job, and we’ll tell you honestly if your roof needs new decking or if the existing sheathing is sound enough to reuse.
Flat Roof Replacement in Montclair
Flat roof replacement in Montclair is common because so many of the city’s homes were built with low-pitch or built-up tar-and-gravel systems. These roofs take a beating from Inland Empire summers, when surface temperatures exceed 150°F and UV exposure bakes the membrane until it cracks. We replace flat roofs on single-family homes, additions, garages, and mobile homes throughout 91763, and the work typically runs $9,000 to $16,500 depending on square footage, insulation requirements, and whether the existing roof is a tear-off or can be recovered.
Membrane Systems for the Inland Empire
Montclair’s heat demands a membrane that can handle thermal movement without splitting at the seams. We install single-ply and modified bitumen systems, and we recommend materials based on how the roof handles expansion and contraction from Montclair’s 40-degree summer-to-winter swings. The goal is a roof that won’t fail at the first Pacific storm after a long, dry summer.
When Repair Becomes Replacement
We repair flat roofs when the damage is localized, and we’ll tell you directly when patching won’t hold. If the membrane is cracked across large sections, the flashing at penetrations is dried out, or the roof has multiple active leaks, replacement is the honest recommendation. Our Roof Replacement team handles tear-off, decking inspection, and new membrane installation as one continuous job, with permits pulled through Montclair’s building department.
Trusted Brands We Service in Montclair
We install products from seven roofing manufacturers, and that means we’re not married to any single system. In Montclair, the most common requests are GAF Timberline HDZ for architectural shingle reroofs and Atlas or Tamko for budget-conscious replacements where the original roof was a standard composition shingle. We stock fast-moving materials locally for Montclair jobs, so once your permit clears, we’re not waiting on supply chain delays. The brand we recommend depends on your roof’s pitch, your home’s exposure, and the budget you’ve set, and we’ll walk through the trade-offs honestly before you choose.

AfterCommon Roof Replacement Problems We See in Montclair Homes
- Original skip sheathing that fails when re-nailed. Montclair homes built in the 1950s and 1960s often have 1×6 or 1×8 boards spaced with gaps, and the wood has had 60 years to dry out and split. When new fasteners miss the boards or split them, the roof never seals properly at the eaves.
- Dried-out flat-roof membranes that crack after summer UV exposure. Montclair’s summer heat bakes tar-and-gravel and single-ply roofs until the surface becomes brittle, and the first heavy winter storm reveals the failures. We schedule our Montclair inspections before the rains arrive.
- Undersized fascia and soffit on mid-century homes. When we remove old roofing on a Montclair tract home, we often find fascia boards that can’t carry new drip edge without rot repair. We scope this work before we start, not after we’re already on the roof.
- Mobile-home roof systems in parks along the valley floor. Manufactured homes in Montclair have their own roofing challenges: low structural clearance, original metal or membrane systems, and park rules that dictate what can be installed. We work within those constraints daily.
Pricing for Roof Replacement in Montclair, CA
Roof replacement in Montclair costs more than the same job in a newer inland suburb because of what’s underneath the roof. A standard architectural shingle reroof on a 1,200 square foot single-story home runs $8,500 to $13,000. Add decking replacement and you’re at $10,500 to $18,000. A flat roof replacement on the same footprint runs $9,000 to $16,500. Mobile-home roof replacements typically land between $6,000 and $11,000, depending on the existing system and park requirements. Every quote is free, every change order is written, and every job is priced with the decking already inspected, not guessed at. Call (833) 467-4846 for an exact number on your roof.

FAQs About Roof Replacement in Montclair
Yes, opening a Montclair roof triggers permit inspections, and those inspections often require building-code upgrades that affect your final cost. When the roof is opened, the city inspector can require the decking be brought up to current nailing standards, which frequently means replacing original skip sheathing with solid OSB or plywood. Montclair also enforces current fire-resistance requirements for roofing materials in certain zones, which may affect which products you can install. We pull the permit, schedule the inspections, and build code compliance into your quote so there’s no surprise at inspection time. Call (833) 467-4846 to get a permit-ready estimate for your Montclair home.
You can tell by checking the attic and looking between the rafters after the first roof removal, but the honest answer is you won’t know for sure until the roof is open. Homes built in Montclair before roughly 1975 commonly used 1×6 or 1×8 skip sheathing instead of solid plywood, and the only reliable way to confirm it is to open a section and look. That’s why we inspect the decking as part of every free estimate, and we write decking replacement into the contract as an allowance with a per-sheet price, not an open-ended line item. If your home was built in the 1950s or 1960s in central Montclair, assume skip sheathing is present until proven otherwise.
Yes, in most Montclair mobile-home parks we can install a new roof over the existing metal roof without removing it, provided the structure can handle the added load and the park’s rules permit it. The typical approach is a retrofit roof-over system with either a membrane or a lightweight panel system, and it runs $6,000 to $11,000 depending on the home’s length and the existing condition. But in some cases the original metal is so deteriorated that a full tear-off is the only way to get a roof that lasts. We’ll tell you which path makes sense after we inspect it, and we handle the park’s approval paperwork as part of the job.
Fall and early spring are the best seasons for roof replacement in Montclair, because summer heat makes roofing work harder on materials and winter rains make tear-offs risky. Summer temperatures above 95°F accelerate shingle adhesive failure and make roofing crews work in unsafe conditions, while the first winter storms expose leaks in dried-out membranes. Most Montclair homeowners schedule their inspections in September and October so the work is done before the rainy season. We book Montclair jobs year-round, but we’ll recommend the window that gives your roof the longest service life.
Yes, we price by the roofing square, which is 100 square feet of roof area, and a typical Montclair home runs $350 to $550 per square for architectural shingles, depending on tear-off depth, decking condition, and material choice. That per-square price includes tear-off and disposal, underlayment, flashing, drip edge, ridge venting, and the shingles themselves. Decking replacement is priced separately by the sheet, and we write that into the contract as a fixed per-sheet rate before we start. Flat roofs are priced differently, at $700 to $1,100 per square for membrane systems, because the labor and materials are different. Call (833) 467-4846 and we’ll measure your roof and give you a written line-item quote.
