Owens Corning Roofing in Montclair, CA | Tilecraft Roofing
Tilecraft Roofing provides independent Owens Corning shingle and flat-roof service across Montclair, CA, and nearby areas like Owens Corning in Claremont. We install, repair, and replace Owens Corning roofing systems on the city’s older tract homes and mobile-home parks. The thing that sets our Owens Corning work apart here is simple: we understand how Inland Empire heat and low-pitch roofs stress these shingles differently than they would in a foothill city. Call (833) 467-4846 to schedule a roof inspection.
We carry genuine Owens Corning shingles and matching accessories, and our crew has worked on hundreds of Montclair roofs over the years. You get a contractor who knows the product line without being tied to a single manufacturer’s sales pitch.
Why Montclair Residents Choose Us for Owens Corning Service
Owens Corning makes a solid shingle. But any shingle is only as good as the roof it sits on and the hands that put it there. Ruben Castellano, our owner, learned the trade at East Los Angeles College’s construction technology program and spent years on residential and commercial roofs across the Southeast LA corridor before building Tilecraft. He grew up a few blocks from Hollydale Regional Park and has worked roofs within a few miles of home his entire career.
We stock Owens Corning Oakridge and Duration architectural shingles, plus matching ridge caps and underlayment, so a Montclair repair doesn’t stall waiting on parts. When you call about a leaking roof near Montclair Place or a sun-baked flat section in a mobile-home park off Holt Boulevard, we show up with the right components and an honest read on whether repair beats replacement.
We’re an independent contractor. No authorization from Owens Corning, no corporate sponsorship. That independence means we’ll tell you when an Owens Corning system fits and when another material does the job better. Seven leading brands, one crew. We look before we quote.

Common Owens Corning Roofing Problems We Solve in Montclair
Hot, dry summers followed by sudden Pacific storms create a predictable pattern of failures on Owens Corning roofs here. What we see most often across Montclair:
- Granule loss on sun-baked 3-tab shingles. Original Owens Corning Supreme 3-tab roofs from the 1990s and early 2000s on Montclair’s 1950s – 1970s tract homes shed granules aggressively after years of 95°F+ surface heat. Bare fiberglass mat shows through, and the shingle loses its UV shield. Once that happens, the roof ages fast.
- Curling and thermal-crack splitting. Shingles expand and contract through Inland Empire heat cycling. On low-pitch tract roofs, that movement concentrates at the shingle edges. We regularly see Owens Corning tabs that have curled up and cracked at the corners, especially on south-facing and west-facing roof planes.
- Lifted tabs from uneven seal-down strip bonding. Owens Corning seal-down strips soften in summer and re-bond unevenly as temperatures swing. By the time the first heavy winter rain hits Montclair, tabs that never re-sealed properly lift and tear. A roof that looked fine in October leaks in December.
- Flashing and vent-boot leaks at low-pitch transitions. Montclair’s older homes often have low-slope rear additions or carport tie-ins where the shingle field meets a flatter membrane section. Dried-out flashing and cracked vent boots at these transitions are a common entry point for wind-driven rain.
- Decking and underlayment degradation under shallow-slope sections. Shingle roofs on low pitches hold heat and pond slightly after downpours. The underlayment beneath aged Owens Corning shingles dries out, wrinkles, and eventually lets moisture reach the decking. By the time we see interior staining, the decking often needs spot repair too.
Owens Corning Service in Montclair: What Local Conditions Mean for Your Roof
Montclair sits on the valley floor where summer roof surface temperatures routinely pass 150°F. The housing stock here is different from the steep, comp-shingle roofs you’d find in newer inland suburbs. Much of Montclair was built between the 1950s and 1970s as modest single-story tract homes with low-pitch or nearly flat roofs. The city also has a significant number of mobile and manufactured homes in parks along the valley floor. That changes how Owens Corning shingles perform here.
A shingle is designed to shed water by gravity. On a steep roof, water runs off fast. On the shallow slopes common in Montclair, water moves slower and wind can drive it sideways under the shingle laps. Combine that with months of UV exposure that dries out the asphalt and breaks down the seal strips, and you get a roof that fails at the seams right when the first storm arrives. This is the pattern we see every fall: months of dry heat, then a Pacific front that reveals every weak point on low-slope Owens Corning roofs. We plan our pre-rain inspection schedule around it, because a roof checked in September rarely surprises anyone in December.
One memorable job near Montclair Place illustrates the pattern. Our crew found a 1990s-era Owens Corning 3-tab roof with heavy granule loss and lifted tabs after a long dry summer. The first winter storm pushed water past tired flashing at the low-pitch rear section. We replaced the failed flashing, repaired the decking where moisture had softened it, and finished the field with matching Owens Corning architectural shingles so the low-slope transition sheds water again. Repair when repair is right, replace when it’s not.
Owens Corning Models & Products We Service in Montclair
We install and repair the Owens Corning lines most often used on Montclair homes:
- Oakridge architectural shingles. A mid-weight architectural shingle that handles Inland Empire heat better than 3-tab. We stock Oakridge in common Montclair colorways.
- Duration architectural shingles. Owens Corning’s heavier architectural line. The added thickness resists curling on low-pitch sections better than thinner shingles.
- Supreme 3-tab strip shingles. Still found on many original Montclair tract roofs. We match these for smaller repairs when the surrounding field is intact.
- WeatherLock and ProArmor underlayment systems. Used on re-roofs where deck protection matters at shallow slopes and around penetrations.
When a repair stays within the Owens Corning system, we use genuine Owens Corning shingles and matching ridge caps. When aftermarket flashing or underlayment outperforms the brand’s accessory line, we say so and use the better component. You get the right material for your roof, not whatever we have sitting in the yard.

Full Owens Corning re-roofs on the city’s modest single-story tract homes generally land between $9,500 and $16,000 depending on the roof size, pitch, number of penetrations, and whether the existing decking is sound.
What drives repair cost here: access on low-pitch or mobile-home roofs, the amount of shingle matching needed, and whether decking below the shingles has softened from trapped moisture.

FAQs – Owens Corning Roofing in Montclair
No. We are an independent roofing contractor. We install and repair Owens Corning products regularly and know their lines well, but we carry no manufacturer authorization or endorsement. What we do carry is our own workmanship warranty and years of hands-on experience with Owens Corning shingles on Montclair roofs. If your project matters more for the manufacturer’s certification, we’ll tell you that directly.
It’s the combination of sustained high heat and low-pitch construction. Montclair summers push roof surface temperatures past 150°F, which accelerates granule loss and dries out the asphalt. The city’s older tract homes often have shallower slopes than newer developments, so shingles bake harder and water moves slower when rain finally arrives. A properly ventilated roof with adequate pitch will outlast one that isn’t, regardless of brand. Call (833) 467-4846 and we’ll inspect what’s actually going on.
Short answer: yes, in most cases. We repair the shingle field, replace failed flashing, and address the transition points where low-slope sections meet the shingles. But if the existing shingles are heavily granule-lossed and curling across multiple planes, patching becomes a losing game. We’ll tell you honestly when a repair buys you another season or two and when it’s time to re-roof. Estimates are free.
For full replacements on Montclair’s tract homes, we most often recommend Owens Corning Duration or Oakridge architectural shingles. Both handle the heat-to-rain swing better than 3-tab, and the added weight resists the curling we see on low-pitch sections. For mobile-home and manufactured-home applications with flat or membrane roofs, we use Owens Corning accessory underlayments where they suit the system and appropriate membrane products from our other brand partnerships.
Yes. After a long dry summer, the first strong winter storm is when most Montclair leak calls come in. We prioritize emergency leak repair for existing customers and respond to new calls as quickly as the weather allows. If water is coming in, call (833) 467-4846 right away. We’ll get someone to your roof and stop the active leak before the next system moves through.
