Owens Corning Construction in Mountain View, CA | San Bernardino Contractors
San Bernardino Contractors provides independent Owens Corning roofing installation and repair across Mountain View, CA, from the historic bungalows of Old Town to the Eichler tracts west of the city. What separates our Owens Corning work here is simple: we spec the roof to the lot. A 1920s bungalow in 94041 under design review needs different detailing than a 1970s flat-roof Eichler in 94040 than a 2010s infill house in 94043, and we’ve opened up enough of each to know exactly where the failure points are. Call (855) 473-5620 to schedule a free estimate.
We’re not manufacturer-affiliated or authorized. We source Owens Corning products through distributors and build to the manufacturer’s published installation specs. Ruben Castillo, our owner, grew up watching his uncle reroof houses and frame garages on a shoestring budget in San Bernardino’s Westside, and that hands-on education stuck: if it’s not built right the first time, you’re just paying for it twice.

Why Mountain View Residents Choose Us for Owens Corning Service
We know Owens Corning’s product lines the way a mechanic knows engine families. Oakridge, Duration, Duration STORM, Supreme, Classic, WeatherLock, VentSure. We know which line belongs on which roof pitch, which underlayment detail holds up through a wet Mountain View winter, and which vent pattern actually moves air through a house with no attic cavity. That’s the difference between a roofer who slaps shingles on and a contractor who understands the assembly.
Our coverage spans all of Mountain View: 94040, 94041, 94042, and 94043. We’ve worked on post-war ranchers with radiant slab heat, Eichler-era flat roofs, 1900s bungalows with unbolted cripple walls, and the newer infill near Shoreline. For full local context, see our Mountain View service area page. When you call, we’ll talk through your structure type, your roof pitch, and your venting situation before we ever quote a number.

Common Owens Corning Construction Problems We Solve in Mountain View
- Granule loss and seal-strip failure on south-facing planes. Mountain View gets serious summer UV, and older Owens Corning 3-tab or first-generation architectural shingles on a post-war rancher in 94040 often show accelerated granule shedding and early seal failure. Once seal strips let go, the next wind event lifts entire tabs. We inspect every plane differently because west and south exposures here degrade faster than north and east.
- Wind-driven rain intrusion at valleys and step flashing. When a low-slope or Eichler-era roof was re-shingled without proper WeatherLock underlayment detailing at valleys, winter storms push water sideways through gaps no granule layer will stop. We see this on older Mountain View re-roofs where the original built-up roof was torn off and architectural shingles went down with too little slope and too little attention to the change in assembly requirements.
- Nail pops and ridge separation from expansive soil movement. Clay-heavy North County soil moves seasonally, and older Mountain View homes without modern foundation reinforcement flex just enough to break shingle fasteners and ridge cap sealant. It looks like a fastener problem. It’s actually a soil-and-structure problem showing up on the roof. We repair the deck fastening and then address what’s causing the movement if the homeowner wants to.
- Rotted fascia and edge failure on bungalows. Old Mountain View bungalows often have short or missing drip edge, and when gutters clog with oak and redwood debris, water backs up under the starter course and rots the eave line. We replace the drip edge, repair the rot, and dial in the starter strip so the Owens Corning system has a straight, dry foundation to begin on.
- Ponding water on Eichler-era flat and low-slope roofs. In 94040’s Eichler tracts, original single-ply and built-up roofs have no slope to shed water, so any low spot becomes a standing pond that eventually works through the membrane. We see this constantly. The fix is a properly detailed low-slope Owens Corning system with drainage that moves water off the edge instead of holding it there.
Owens Corning Service in Mountain View: What Local Conditions Mean for Your Equipment
Here’s the thing about Mountain View that shapes every Owens Corning job we do here: the city runs on two completely different housing worlds, and the roof spec has to match the lot. On the west side, the Eichler-era flat-roof homes in 94040 were built with shallow single-ply or built-up roofs, radiant slab heat running under the deck, and no attic space at all. When our crews stripped a failing built-up roof near the west side, we found exactly that: no chase for mechanicals, no venting cavity, and radiant slab heat cooking the old membrane from underneath. We went down to the sheathing, laid self-adhered underlayment and a proper low-slope Owens Corning in Sunnyvale system, and detailed the drains so winter rain sheds instead of ponding.
Two miles away in Old Town, a 1920s California bungalow in 94041 sits under the city’s historic and neighborhood-compatibility review, so changing a visible roof covering or color can require design review before the building permit. That step doesn’t exist on the newer 94043 infill near the Googleplex, where a same-week re-roof permit is routine. A contractor who gives both homes the same spec is guessing. We don’t guess.
Owens Corning Models & Products We Service in Mountain View
We install and repair the full Owens Corning residential line. That includes Oakridge and Oakridge TruDefinition architectural shingles, Duration and Duration STORM architectural shingles with their wider nail zone, and Supreme / Classic 3-tab shingles on older budget re-roofs. We use Owens Corning-manufactured accessory components: starter strip, hip-and-ridge, WeatherLock self-adhered underlayment, and VentSure ventilation products. That keeps the assembly coherent. We substitute equivalent-quality aftermarket flashing only where it performs better on a given detail, and we’re upfront about why.
When shingles are still sealing and the deck is sound, we repair localized damage. When a roof shows curl, granule loss, and multiple failed seal strips across an entire plane, replacement is the honest call. We don’t resurface a failing deck with new shingles and call it done.

FAQs – Owens Corning Construction in Mountain View
Shingles are rated for specific minimum slopes, and most Eichler-era roofs fall below that threshold. On a low-slope roof, we install an Owens Corning low-slope system with self-adhered underlayment and proper drainage detailing rather than forcing a shingle product into a slope it won’t seal on. We’ve opened up enough of these roofs to know the difference, and the wrong call leaks within two winters. Call (855) 473-5620 and we’ll assess your exact slope before recommending anything.
Yes, a building permit is required for a re-roof in Mountain View, and homes in the Old Town historic / neighborhood-compatibility review areas may need design review before the permit issues if the visible roof covering or color changes. That means the color and material choice can matter beyond the warranty. We handle the permit and design review paperwork, and we’ll walk you through which Owens Corning colors pass review in your district. Call (855) 473-5620 before you pick a color, and we’ll confirm what’s approvable for your block.
Something most contractors won’t tell you: when the roof is open on a 1950s ranch here, you’ll often have a clear look at the top plates and the existing venting path, which is the moment to check whether your attic or ceiling cavity is actually moving air. We’ve seen original single-pane windows and no insulation under decks that should have been retrofitted years ago. While the Owens Corning system goes on, we can evaluate whether your venting setup actually works with the new roof, and we’ll flag it before it becomes a problem under the shingles.
Valley leaks are almost always a detailing problem: too little underlayment, missing WeatherLock at the valley center, or step flashing that was installed backward or not at all. Shingle brand is rarely the cause. On Mountain View low-slope roofs, we re-detail valleys with self-adhered underlayment up each side and verified flashing overlap so water moves downhill without finding the nail line. Call (855) 473-5620 and we’ll trace the leak to its actual source before quoting a repair.
Not always. Nail pops and ridge cap separation on a house with expansive-soil movement often mean the fasteners lost their grip, not that the shingle material failed. We check the deck, the underlayment, and the ridge line first. If the deck is sound and the shingles still seal, we repair the fastening and re-secure the ridge. If the movement has cracked seal strips across planes, replacement is the only honest call. Estimates are free: call (855) 473-5620.
