Owens Corning Roofing in San Marino, CA | Marquis Roof Repair
Marquis Roof Repair provides independent Owens Corning service across San Marino, from full replacements to precise repairs on shingle and tile-underlayment systems. What makes our Owens Corning work different here is simple: San Marino’s design review treats visible roofing as heritage, not just weatherproofing. That means the OC shingle or underlayment you choose has to pass scrutiny before it ever gets installed. Call (866) 705-2978 for a free estimate, and we’ll walk you through what your roof actually needs. We also provide Pasadena Owens Corning service.
Why San Marino Residents Choose Us for Owens Corning Service
We read Owens Corning’s installation specs closely, because San Marino won’t accept shortcuts anyway. The city’s design and cultural-heritage review means a roofline isn’t just a roofline here. It’s a visual statement on a 1920s Spanish Colonial Revival or a 1930s Tudor. Our crew has worked on enough of these estates to know which OC lines hold up under decades of San Marino sun and which ones will fight you at the permit counter. Ron Thibodeau, our owner, grew up learning that good work speaks for itself and shortcuts always show up eventually. That’s the standard we bring to every Owens Corning job in San Marino.
We carry genuine OC shingles and underlayments when they match your existing system, and we don’t push a full replacement when a targeted repair will hold. Seven manufacturer lines, one point of contact. From first inspection to final shingle, the job gets done to the Marquis standard.

Common Owens Corning Roofing Problems We Solve in San Marino
- Granule loss on OC architectural shingles. San Marino’s long dry summers bake roofing surfaces for months on end. Intense UV breaks down the binder that holds granules to the shingle mat. We regularly see Oakridge and Duration roofs in 91108 where the granules are washing into the gutters and the fiberglass mat is starting to show through.
- Wind-lifted or creased shingle tabs along ridgelines and dormers. Many San Marino estates sit on generous lots with complicated multi-ridge and dormered rooflines. Mountain-edge wind whips through those ridges during winter storms. We find creased tabs where the sealant strip gave out and the shingle folded back on itself.
- Underlayment failures that show up as ceiling stains before the shingles look bad. An OC system only performs as well as the felt and battens beneath it. On older San Marino homes, we’ve opened up roofs where the shingles looked serviceable but the underlayment underneath had turned to powder after eight decades of thermal cycling.
- Nail-sick and rusted battens under original clay tile. Under 1920s barrel tile near Huntington Drive, we’ve found OC underlayment that was lapped decades ago has disintegrated, and the battens holding the tile are rusted through. The tile looks fine from the street. The roof beneath it is gone. Interior leaks appear after the first hard atmospheric-river storm.
- Flashing failures at dormers and valleys. San Marino’s older estates have more dormers and roof intersections than most homes built today. We repair flashing at those transition points constantly. Water finds the seam where the flashing has pulled away or corroded, long before the shingles themselves fail.
Owens Corning Service in San Marino: What Local Conditions Mean for Your Equipment
Here’s what separates a San Marino Owens Corning job from the same work in San Gabriel or Owens Corning repair in Alhambra: the city’s design-review and cultural-heritage process scrutinizes visible roofing materials before you ever pull a permit. Tile-matching, color, and profile drive the project as much as waterproofing does. That means an OC shingle or tile-underlayment job here has to match the existing roof’s look and character before anything gets approved. On a quick asphalt overlay in a neighboring city, nobody asks whether the replacement shingle matches the architectural intent of a 1920s Mediterranean villa. In San Marino, they do. We’ve worked enough of these reviews to know which OC lines and colorways will pass and which will stall. That local knowledge is the difference between a permit that moves and a project that sits.
On a Spanish Colonial Revival estate near Huntington Drive in the 91108 ZIP, our crew pulled original 1920s clay tile and found the OC underlayment beneath it disintegrated and the battens nail-sick after eight decades of thermal cycling. We set the reusable tile aside, replaced the failed underlayment and rusted battens, repaired flashing at the dormers, and reset the original barrel tile so the visible roof passed the city’s review while the waterproofing was actually rebuilt. That’s the kind of job San Marino demands, and it’s the kind we’re built for.
Owens Corning Models & Products We Service in San Marino
We install and repair the OC lines most common on San Marino homes: Oakridge architectural asphalt shingles, Duration (TruDefinition) architectural shingles, and Supreme/WeatherGuard 3-tab shingles for smaller ancillary structures. For underlayment, we work with Owens Corning’s RhinoRoof, Deck Defense, and WeatherLock ice-and-water membrane products. Where OC doesn’t make the specific part, we use quality aftermarket membranes and flashing that match the system. On a tile roof, we’ll tell you honestly whether the tile is reusable and only the underlayment needs replacing. We investigate before we recommend.

AfterOwens Corning Service Pricing in San Marino
What you’ll pay depends on what’s actually wrong. A flashing repair or a small shingle patch runs less than a full underlayment replacement under original clay tile. Full replacements on larger San Marino estates with multi-ridge and dormered rooflines run higher because the labor is more involved and the material has to pass design review. A free estimate includes a roof inspection, a written line-item quote, and our honest read on whether repair or replacement makes sense. We won’t push the bigger job if a precise fix will hold. Call (866) 705-2978 for an exact quote. Estimates are free, and the phone call takes five minutes.

FAQs – Owens Corning Roofing in San Marino
No, and we wouldn’t try. San Marino’s design and cultural-heritage review requires visible roofing materials to be approved before installation. We’ll help you prepare the submittal with the OC shingle color, profile, and product spec, and we know which lines have passed review on similar homes in 91108 and 91118. Call (866) 705-2978 and we’ll walk you through the process.
Almost always the underlayment. Original clay tile from the 1920s is often still serviceable, but the OC underlayment beneath it has typically disintegrated after eight decades of thermal cycling. We pull the tile, replace the underlayment and any rusted battens, and reset the original tile. The visible roof stays the same; the waterproofing gets rebuilt. Call (866) 705-2978 for an inspection.
We install Oakridge architectural shingles, Duration (TruDefinition) architectural shingles, and Supreme/WeatherGuard 3-tab for smaller structures. For San Marino’s larger estates with design-review requirements, architectural lines like Oakridge and Duration tend to pass review more smoothly because they offer better color depth and a more substantial profile. Call (866) 705-2978 if you want to see samples before your submittal.
Yes. The burn scar above the city raises debris-flow and wind-driven rain concerns during atmospheric-river storms. Wind-driven rain finds every small gap in flashing or underlayment. We recommend an inspection before each winter rain season, especially on older tile roofs. Call (866) 705-2978 to schedule one.
No. We’re called Marquis Roof Repair for a reason. We investigate before we recommend. If the flashing at one dormer or the metal in one valley is the problem, we’ll quote that repair. We’ll only recommend full replacement when the roof surface or underlayment system has actually reached the end of its life. Call (866) 705-2978 for an honest assessment.
