Owens Corning Construction in Mountain View, CA | Penhallow Remodeling San Jose
We’re an independent contractor installing and repairing Owens Corning roofing across Mountain View, and the quick answer is this: we know how Owens Corning shingles behave on 1950s and 60s ranch homes here, where morning fog, bay wind, and slab-era construction quirks shorten a roof’s life in ways a generic roofer never sees. We provide full roof replacements, targeted repairs, and storm damage response using genuine Owens Corning products. If your Owens Corning roof is losing granules or lifting at the eaves, call (669) 274-2362 for a free estimate.
Why Mountain View Residents Choose Us for Owens Corning Service

Trevor Nash has spent the better part of two decades running remodeling and roofing projects across the South Bay, including a stretch of our Bathroom Remodeling in Mountain View and San Jose’s Willow Glen neighborhood that still stands as some of his cleanest finish work. That same standard carries into every Owens Corning roof we touch in Mountain View. We don’t push a shingle line because a distributor offered us a rebate. We recommend what holds up under Mountain View’s specific conditions, because we’ve torn off enough failed roofs here to know the difference between a product problem and an installation problem.
Our crews arrive in uniform, background-checked, and with a written number before any work starts. That’s the Kingswell standard, and it’s been our operating rule since 2004. For Owens Corning roofs, that means we quote genuine Owens Corning shingles, nails, ridge caps, and underlayment, not a cheaper lookalike that voids the wind warranty. We’re part of the Kingswell family of companies, independently owned and operated, and our Owens Corning sales & service work reflects that independence.

Common Owens Corning Construction Problems We Solve in Mountain View
- Granule loss on north-facing slopes. Mountain View’s morning fog and heavy dew cycles settle hardest on north-facing roof planes. Older Owens Corning shingles, especially the Supreme AR line from the 1990s and early 2000s, shed granules faster here, which thins the shingle and exposes the asphalt mat. Homeowners first notice granules in the gutters, then bare patches.
- Lifted and creased shingles from bay wind. High-wind events off the San Francisco Bay hit shallow-pitch ranch roofs in Old Mountain View particularly hard. Owens Corning shingles are rated for wind, but if they were nailed too high or with the wrong nailing pattern during a mid-century installation, edges lift and crease. Once creased, the shingle’s structural integrity is gone.
- Blow-offs along eaves and rakes. Many original Mountain View roofs had shingles nailed by hand with inconsistent patterns. On windy nights, the shingles along the eaves and rakes go first, exposing underlayment and inviting water intrusion. We match the remaining Owens Corning shingles when possible, but if more than 30% of the field is damaged, we recommend full replacement.
- Ice-and-water shield failures at valleys and chimneys. Additions and remodels on Mountain View’s small lots often left valleys and chimney flashing underprotected. Winter rainstorms track water into living spaces at these points. We rebuild valleys with Owens Corning Ice & Water Shield and proper metal flashing, not a bead of caulk.
- Improperly flashed roof penetrations around slab-era mechanical chases. This one’s specific to Mountain View. Homes with concrete slab foundations often ran plumbing and HVAC chases through the roof at odd angles. The original flashing around those penetrations was frequently nail-on with no counterflashing, so moisture creeps in silently for years before anyone sees a stain.
Owens Corning Service in Mountain View: What Local Conditions Mean for Your Equipment

In the Old Mountain View neighborhood, many original 1950s homes sit on concrete slab foundations with underslab ducting that corrodes and collapses over time. Here’s what that has to do with your Owens Corning roof: when we reroof these homes, we often find that original roof vents and penetrations were improperly flashed around slab-era mechanical chases. The original builders ran plumbing stacks and vent pipes through the roof at shallow angles, then slapped a nail-on flange over the gap. No counterflashing, no ice-and-water shield. The result is hidden moisture intrusion that only shows up after new shingles are installed, because the old shingles were doing the sealing work the flashing never did. That’s a Mountain View-specific failure mode. In San Jose or Santa Clara, you see the same era of housing, but the slab-era chase pattern in Old Mountain View’s 1950s tract is unusually concentrated, and the fog off the bay keeps those penetrations damp for more hours per year. When we quote an Owens Corning roof here, we budget for new flashing and water shield at every penetration, because we know what’s underneath before we tear off.
Our crew reroofed a 1958 rancher on Calderon Avenue in Old Mountain View last fall. The homeowner had Owens Corning Duration shingles that were losing granules and lifting at the eaves after a series of high-wind nights off the Bay. During tear-off, we found the original valley metal had corroded through, and the chimney flashing was nail-on with no counterflashing. We replaced the sheathing in two spots, installed new Owens Corning Duration Storm shingles in Onyx Black, and rebuilt the valleys with Ice & Water Shield. The roof now shrugs off Mountain View fog and wind, and the crew finished before the winter rains.

FAQs – Owens Corning Construction in Mountain View
Yes, when installed correctly with proper nailing patterns and underlayment. Owens Corning Duration Storm shingles are rated for high-wind zones. The failure we see in Mountain View is rarely the shingle itself. It’s the 1950s-era nailing pattern, the missing counterflashing, or the fog-driven granule loss on north-facing slopes from roofs that have simply aged out. We install to manufacturer spec, which means the wind warranty actually applies.
In most cases, yes. Owens Corning has kept its core color lines consistent for years, so a repair on an eight-year-old Duration roof is matchable. But on a roof near end-of-life, or when more than 30% of the field is damaged, we recommend full replacement instead of a patchwork. Matching shingles on a failing roof just means you’ll call us again next year. Call (669) 274-2362 and we’ll tell you which situation you’re in.
They don’t, directly. What interacts is the mechanical chases that pierce the roof around those slab foundations. The original flashing was frequently inadequate, so a new Owens Corning roof installed without addressing those penetrations will leak at the penetrations, not at the shingles. We rebuild every penetration with new flashing and Ice & Water Shield as part of any Mountain View reroof, because we know what’s under the old shingles.
We install genuine Owens Corning shingles and accessories to the manufacturer’s install specification, which is what keeps the manufacturer warranty valid. We are an independent contractor, not a manufacturer-affiliated or authorized installer, so we don’t sell the warranty; we earn it by installing correctly. On top of that, every job carries our 365-Day Done Right Promise in writing: if the work fails inside a year, we come back and fix it at no charge.
A full Owens Corning Duration replacement on a typical 1,200 to 1,800 square foot Mountain View ranch runs $8,000 to $20,000 depending on teardown layers, sheathing replacement, and penetration work. The slab-era penetrations in Old Mountain View can add to the flashing budget, but ignoring them costs more later. Call (669) 274-2362 for a written quote, free.
