Owens Corning Construction in Mountain View, CA | Timberline Contractors
We provide independent Owens Corning roofing service across Mountain View, from tear-offs on 1950s ranchers in 94040 to full replacements on Eichler additions near Monta Loma, and we also handle Owens Corning repair in Los Altos. The difference here comes down to one thing: Mountain View’s mid-century housing stock demands that an Owens Corning roof be installed around shallow eaves, low-slope tie-ins, and slab-embedded radiant heat. Get that wrong and you’ll be re-roofing in five years. Call (866) 253-5808 for a free estimate from a contractor who has worked these roofs for years.
Why Mountain View Residents Choose Us for Owens Corning Service
We have worked Owens Corning materials into enough Mountain View homes to know exactly where they perform well and where they need reinforcement. The neighborhoods around downtown and the 94040/94041 ZIPs are packed with post-war ranchers and Eichlers that were roofed decades ago with first-generation Owens Corning 3-tab shingles. Today, those original roofs are failing, and the replacement conversation is rarely straightforward. Our lead, Nelson Fung, started his career learning trade fundamentals at Los Angeles Trade-Technical College and has spent years since swinging hammers on everything from bungalow remodels to commercial builds. He brings that same hands-on rigor to every Owens Corning roof we install or repair. We are an independent Mountain View General Contractor, not an Owens Corning authorized dealer, and that independence means we spec exactly what your home needs, nothing more.

Common Owens Corning Construction Problems We Solve in Mountain View
- Low-slope and shallow-pitch failures on Eichler additions. Many Eichler additions and garage roofs in Mountain View were built with slopes below Owens Corning’s minimum recommended pitch. The result is repeated tab cracking and seal failure at the exposure line. We see this constantly in the Monta Loma and Stierlin Estates neighborhoods.
- No intake ventilation on 1950s-60s ranchers. Those minimal eave overhangs look great, but they leave little room for soffit intake vents. Without intake, an Owens Corning shingle roof bakes from below. We see premature granule loss and aging concentrated near the ridge on homes that never had proper airflow.
- Thin or skip sheathing under first-generation OC layers. Many 94040 and 94041 homes still have the original 1×6 or skip sheathing from when the first Owens Corning layer went down. That old deck telegraphs through new shingles and weakens wind uplift resistance. We inspect the deck before we ever lay a new shingle.
- Winter rain-driven leaks at flashing points. Mountain View gets almost all of its rain November through March, and the leaks that show up during those storms are usually flashing failures at roof-to-wall intersections or skylight curbs, not shingle failures. We diagnose flashing problems first because replacing pristine shingles over a bad flashing junction is money down the drain.
- Radiant-heat copper loops complicating roof-and-addition work. Eichler homes around Mountain View have copper radiant heating tubes embedded in the slab. Any structural work that cuts into the slab risks rupturing that loop. When a roof replacement ties into an addition, the new eave height and roof plane have to be drawn around that system. Out-of-town contractors often miss this entirely.
Owens Corning Service in Mountain View: What Local Conditions Mean for Your Roof
In Mountain View’s Eichler neighborhoods around Monta Loma and Stierlin Estates, the original radiant-heat copper tubing embedded in the concrete slab is the single biggest wildcard on any roof-and-addition project. You cannot simply trench through those loops to move plumbing or set new posts. That means a roof replacement that ties into an addition has to be planned around a heating system you cannot see and cannot easily relocate. The new roof plane, the eave height, and the flashing tie-in at the roof-to-wall junction all have to be drawn with the slab’s tubing map in mind. We have watched out-of-town crews plan a normal addition roof and then discover mid-project that the slab is threaded with copper. In Mountain View, this is not a rare surprise. It is the default on Eichler-era homes. On a Monta Loma Eichler we tore off a failing Owens Corning Oakridge roof and found the low-slope section over the rear addition had been shingled below minimum pitch years earlier, with no intake venting at the shallow eaves. We rebuilt the low-slope area with a proper membrane-to-shingle transition, added intake and ridge ventilation, and re-flashed the roof-to-wall tie-in to the addition. We kept the new roof plane clear of the slab-embedded radiant loops below. That job taught us exactly how much of Mountain View roofing is about respecting the original house while replacing what failed.
Owens Corning Models & Products We Service in Mountain View
We work with the full Owens Corning shingle and accessory line: Oakridge architectural shingles, Duration premium architectural shingles, and the Supreme and WeatherGuard 3-tab shingles we still find on older tract roofs throughout Mountain View. We also install and repair the TruDefinition and Total Protection underlayment and accessory systems, including starter strips, ridge caps, and hip components. Our parts approach is simple: stay within the Owens Corning component system. Mixing brands voids the material warranty, and we will not do that on your roof. For fast Mountain View turnaround, we keep common OC starter, ridge, and ventilation components in our local inventory, which means less waiting when a storm repair calls for matching accessories on a Wednesday.

FAQs – Owens Corning Construction in Mountain View
Yes, when the roof work is confined to the existing roof plane and no new structural posts or slab cuts are required. The risk appears when the roof ties into an addition or new post footings have to be set. In those cases, we map the slab’s radiant loops from the original plans or with thermal imaging before any cutting happens. If a loop is already ruptured, we abandon the in-slab section and retrofit a compatible system rather than patching it badly. Re-roofing an Eichler is absolutely doable; the planning just has to respect the slab. Call (866) 253-5808 for an exact quote on your Eichler roof.
Because almost all Mountain View rain falls November through March, and the leaks that appear during those storms are usually flashing failures, not shingle failures. Roof-to-wall junctions, skylight curbs, and chimney step flashing are the typical culprits. The shingles may look fine. We inspect the flashing system first on any winter leak call in Mountain View because replacing good shingles over a failed flashing detail is wasted money. Call (866) 253-5808 and we will diagnose the leak the right way.
Yes. A full roof replacement in Mountain View requires a building permit, and the city’s permit review culture is shaped by the same scrutiny that governs big-tech campus projects in the area. We pull the permit, schedule the inspection, and make sure the nailing pattern and ventilation details meet code before the inspector arrives. You never have to deal with the city paperwork yourself. Call (866) 253-5808 and we will handle the permit on your Owens Corning replacement.
It matters a lot. Owens Corning shingles are warrantied against premature granule loss and thermal cracking only when the roof deck has adequate intake and exhaust ventilation. Shallow eaves on 1950s-60s Mountain View ranchers often leave no room for soffit intake vents, which means the shingles bake from below. On those homes we typically add eave baffles, custom intake details, or ridge ventilation so the new roof is vented to Owens Corning’s spec. Call (866) 253-5808 and we will tell you what your specific roof needs.
On a low-slope Eichler addition or a shallow-pitch rancher roof, metal can be the better choice because it handles lower pitches and drains rain faster during winter storms. But metal costs two to three times what a quality Owens Corning shingle roof costs. If your roof has enough pitch and we can correct the ventilation, Owens Corning Duration shingles are often the smarter value. We install both, and we will give you a straight comparison for your specific roof. Call (866) 253-5808 for a free estimate.
