Owens Corning Construction in Mountain View, CA | Ashford Contractors
We’re an independent Owens Corning contractor serving Mountain View, CA, and we’ve worked with their roofing systems for more than a decade. Most Mountain View calls come down to one thing: flat and low-slope roofs ponding water at the seams, often on mid-century homes that were never built for today’s storm patterns. Call (877) 752-3868 for a free estimate on Owens Corning roof repair or replacement anywhere in Mountain View.
We know Oakridge® and Duration® shingles inside out, but we’re not authorized, sponsored, or endorsed by Owens Corning. We’re simply a contractor that’s spent years installing, repairing, and replacing their products across the Bay Area, including Owens Corning in Sunnyvale. If you own an Eichler or rancher with a flat roof in Mountain View, you’re dealing with drainage and flashing details most roofing crews miss. That’s where we come in.
Why Mountain View Residents Choose Us for Owens Corning Service
Mountain View homes are not like the rest of the Peninsula. The older single-story stock south of El Camino and through the 94040 and 94041 neighborhoods carries flat and low-pitch roofs that pond water when a real storm hits. We’ve been on enough of those roofs to know exactly where the seams fail, and which Owens Corning products hold up.
Glen Mossier, our owner, trained in construction technology at Skyline College in San Bruno. He learned framing, mechanical systems, and materials science the way they actually show up on a job site. He’s the one who taught our crews that on a low-slope roof, the underlayment matters as much as the shingle above it. That’s why we use Owens Corning WeatherLock® underlayment on nearly every Mountain View repair.
We stock OEM Owens Corning accessories locally, so Mountain View customers aren’t waiting on parts shipped from out of state. If your Duration® shingles are lifting at the sealant strip or your flat roof is ponding at the flashing, we can usually diagnose and repair it the same week.

Common Owens Corning Construction Problems We Solve in Mountain View
- Sealant strip failure on Duration® shingles. On low-slope roofs without proper adhesive activation, the sealant strip never fully bonds. When the first atmospheric-river storm blows through Mountain View, shingles lift and water gets under. We see this on the flat-roof ranches in the 94041 ZIP every winter.
- Granule loss on Oakridge® shingles. South- and west-facing roof planes in Mountain View take months of uninterrupted summer sun. Oakridge® shingles age faster under that kind of UV and thermal cycling. Once you see granules in the gutters, the shingle backing is degrading.
- Ponding water at flat-roof seams. Owens Corning modified bitumen and low-slope membranes fail most often where water sits. Mountain View’s mid-century homes often have drains that aren’t positioned for heavy rain. We re-detail flashing and adjust drainage so water moves off instead of pooling.
- Inadequate ventilation in Eichler post-and-beam roofs. Those open-beam ceilings look great, but they trap heat and moisture. Without proper airflow, Owens Corning underlayments and shingle backings break down. We address ventilation when we replace the roof, not after the shingles cave.
- Flashing failures at roof transitions. Where a flat roof meets a pitched section or a skylight curb, the flashing takes the abuse. We reinforce those transitions with Owens Corning WeatherLock® and proper metal detailing.
Owens Corning Service in Mountain View: What Local Conditions Mean for Your Equipment
The thing about Mountain View is that the permitting department treats even a modest roof repair like a design review when the home sits near the downtown transit corridor or in a historic overlay. We’ve had Owens Corning roof replacements on 94040-era homes require drainage and seismic calculations that add two to three weeks before we can even pull the permit. That’s not a delay we’re causing; it’s the city doing what Mountain View does. For homeowners, it means planning your Owens Corning roof project around the permit cycle, not just the weather. The flat and low-slope roofs common to the postwar housing south of El Camino make this even more pressing, because a roof that’s already ponding water can’t wait through a long review while winter approaches. If your home is in the 94040 or 94041 ZIP, we’ll flag the permit path early so you’re not surprised.
One job that stays with us: a homeowner on Phyllis Avenue in the 94041 ZIP had an original flat roof with Owens Corning Oakridge® shingles ponding water at the seams after a winter storm. We removed the failed section, replaced the underlayment with WeatherLock®, and re-detailed the flashing to slope toward new drains. That averted a full replacement and stopped the leak. Glen’s rule on those calls is simple: fix the drainage first, then address the shingle.
Owens Corning Models & Products We Service in Mountain View
We install and repair the Owens Corning product lines most common on Mountain View homes: Oakridge® Architectural Shingles, Duration® Series Shingles, TruDefinition® Duration® Shingles, and WeatherLock® Roof Underlayment. When a repair calls for new material, we use OEM Owens Corning accessories rather than generic substitutes. The reason is straightforward: those products were designed to work together as a system, and mixing aftermarket parts voids the warranty and shortens the roof’s life.
For standing seam metal roofs, we handle the full installation scope. And for flat or low-slope applications where shingles are the wrong tool, we use Owens Corning modified bitumen and membrane systems with proper drainage detailing.

FAQs – Owens Corning Construction in Mountain View
Can you repair my Owens Corning Duration® shingle roof if it’s leaking at the seams? Yes, in most cases a targeted repair at the seam, using OEM Owens Corning material, will stop the leak and buy you time. If the sealant strips have failed across multiple roof planes, we’ll tell you when replacement makes more sense than another patch. Call (877) 752-3868 and we’ll walk the roof with you.
What Owens Corning roofing products work best for Mountain View’s flat and low-slope roofs? For flat and low-slope applications, Owens Corning modified bitumen and membrane systems with proper drainage detailing outperform shingles. We use WeatherLock® underlayment on nearly every flat-roof repair in Mountain View because it handles the ponding stress better than standard felt.
Does Mountain View’s permitting affect Owens Corning roof installations? Yes. If your home is in a historic overlay or near the downtown transit corridor, the city can trigger a design review even for a straightforward roof replacement. Expect two to three extra weeks for drainage and seismic calculations. We handle the permit paperwork, but the timeline is the city’s.
How does the local climate impact Owens Corning shingle longevity? Mountain View’s dry, hot summers bake south- and west-facing shingles, while concentrated winter rain tests every seam and flashing detail. Oakridge® shingles show granule loss faster here than in coastal fog belts, and flat roofs pond water if drains aren’t maintained.
Do you offer Owens Corning WeatherLock® underlayment for roof repairs? We do. WeatherLock® is our go-to underlayment for Mountain View roof repairs, especially on flat and low-slope sections where water is most likely to sit at the seams. Ask for it by name when you call (877) 752-3868.
