Owens Corning Construction in San Jose, CA | Seaside Contractors
We’re an independent San Jose General Contractor that installs and repairs Owens Corning roofing systems across the city, from the 1940s ranchers in 95110 to the newer townhomes near downtown. The work here runs on a specific calendar: tear-offs and re-roofs get scheduled April through October, and winter calls are almost always leak response on older decks. If you need Owens Corning service in San Jose, call (833) 589-8103 for a free estimate, and we’ll tell you straight whether repair or replacement makes sense.
Why San Jose Residents Choose Us for Owens Corning Service
Our crews handle Owens Corning Duration, Oakridge, and Supreme shingle systems weekly, not as a once-a-year specialty. That repetition matters when you’re diagnosing granule loss on a south-facing slope or a valley leak that only appears during January rains. Glen Sorrento, our owner, studied building construction technology at College of San Mateo and has spent two-plus decades working through nearly every project type the Peninsula and South Bay produce. He’s the one who reviews each roof scope before we quote it, because he wants the same thing you do: a straight answer on whether the deck, the flashing, or the shingle is the actual problem. That includes Owens Corning repair in Seven Trees and surrounding neighborhoods.
We’re not an authorized Owens Corning dealer, and we won’t imply otherwise. What we are is an independent Owens Corning sales & service contractor who installs these systems often enough to know exactly where they fail in San Jose’s specific conditions. And because we’re a full-scope general contractor, not a roofing-only sub, we can spot how a roof issue connects to an ADU addition, a kitchen remodel, or a drainage problem the same afternoon.

Common Owens Corning Construction Problems We Solve in San Jose
- Granule loss on Oakridge and Supreme shingles – San Jose’s long dry summers bake south- and west-facing slopes hard. By year 18 or 20, older three-tabs start shedding granules into gutters and downspouts faster than owners expect. Once the fiberglass mat shows through, repair stops being sensible.
- Wind-lifted or creased Duration shingles along hips and ridges – Winter storm fronts roll through the valley with enough force to expose fasteners that were nailed high or over-driven on a previous re-roof. We see this most often on homes where someone re-roofed in a hurry, and the crease line gives it away.
- Deck and underlayment failures on 1950s-1970s ranchers – Original skip-sheathing or thin plywood that was never re-decked under the old shingle is a recurring theme in the 95110-95113 core. Leaks show up at valleys and penetrations, not out in the field, because that’s where the gaps are.
- Premature seal-strip failure under tree cover – San Jose’s heritage oaks and redwoods keep shaded roof sections damp, which blocks the sun cure that seals shingle tabs. We’ve pulled up shingles in 95112 that simply never bonded.
- Valley flashing failures on tight-lot additions – When a San Jose ranch gets an addition, the new roof line often ties into the old one at a valley. If that transition wasn’t flashed and re-decked correctly, it leaks on the first real rain. We re-work these junctions with Owens Corning underlayment and matching accessories rather than piecing together whatever’s on the truck.
Owens Corning Service in San Jose: What Local Conditions Mean for Your Roof
San Jose’s heritage-tree ordinance catches remodelers and roofers constantly. A mature oak or redwood over the roof line in 95111 or 95112 can require arborist review and a city permit before a tear-off or lot-split proceeds. That means our scheduling and roof ventilation planning have to account for protected canopy overhangs from the first site visit, not as a surprise mid-project. If a branch overhangs the planned work area, the permit conversation happens before we ever pull a shingle. This is a San Jose-specific constraint. Builders in Cupertino or Los Gatos deal with their own tree rules, but the combination of dense postwar lots, aggressive infill pressure, and protected mature canopy here is its own animal. We also plan tear-offs around the city’s dry-season window, because exposing a deck in February means racing the next front. On a 1958 stucco-over-wood-frame rancher off Willow Glen’s dry-season calendar, our crew tore off two layers of failing three-tab and found the original skip-sheathing under the valleys. We re-decked before installing an Owens Corning Duration system with matching underlayment and ridge vent. The homeowner’s complaint was granules clogging the downspouts every fall and a valley drip that only appeared in January rains. The re-deck and new flashing ended both, and we finished before the first wet front of the season.
Owens Corning Models & Products We Service in San Jose
We install and repair the full Owens Corning residential shingle line: Duration with SureNail Technology, Duration Premium and Designer lines, Oakridge architectural shingles, and Supreme three-tabs for budget-sensitive replacements. We pair them with Owens Corning underlayments, starter strips, hip-and-ridge, and ventilation accessories matched to the shingle system, not generic substitutes. Mixing brands is where warranty and performance claims get shaky, and we’re not interested in that conversation. We stock common Owens Corning accessories locally for fast San Jose turnaround, including Owens Corning repair in Buena Vista, and we order wider color or line requests with enough lead time that your dry-season slot stays on schedule.
This same team handles roof replacement and installation, roof repair, and full kitchen remodeling under one contract. If you’re re-roofing as part of a larger San Jose remodel, we plan the sequencing so the roof work doesn’t hold up the interior trades.

AfterOwens Corning Service Pricing in San Jose
Here’s what we currently quote for Owens Corning work across San Jose:
| Service | Typical Range |
|---|---|
| Roof Replacement | $9,440 – $23,600 |
| Roof Repair | $470 – $2,125 |
| Full Kitchen Remodeling | $16,520 – $53,100 |
Roof replacement cost in San Jose is driven by deck condition, tear-off layers, pitch, and whether protected trees affect access. A 1950s rancher with original skip-sheathing will cost more than a 1990s home with solid plywood, because the re-deck is the fix that actually stops the leak. Every estimate includes a written line-item scope, and we walk you through what’s repair versus replace before you commit. Call (833) 589-8103 for an exact quote – estimates are free.

FAQs – Owens Corning Construction in San Jose
Yes. Duration shingles are built with a heavier fiberglass mat and SureNail Technology, which holds fasteners better during winter storm fronts and resists the UV degradation that San Jose’s long dry summers accelerate on south- and west-facing slopes. The ventilation accessories matter just as much here; a properly vented attic keeps the deck from cooking from below during heat waves. Call (833) 589-8103 and we’ll spec the right system for your roof’s orientation.
Yes, but the tree review happens first. A mature oak or redwood over the roof line can require arborist review and a city permit before tear-off proceeds in San Jose. We factor that into the schedule from the first site visit, because protected canopy overhangs affect how we stage the job and where ventilation can go. If you have a big tree over the house, mention it when you call for an estimate.
If the granules are showing up in your gutters every fall and the shingles are curling or showing fiberglass mat, replacement is usually the honest answer. Isolated damage on a roof with solid decking can be repaired, but once granule loss is widespread, the shingle system is near the end of its useful life. Let’s figure out what the job actually needs – then we’ll talk materials. Call (833) 589-8103.
We install Owens Corning underlayments, starter strips, hip-and-ridge, and ventilation accessories matched to the shingle system. Mixing brands is where warranty and performance claims get shaky, so we don’t do it. You get a matched system, not whatever was cheapest at the supply house that week.
Yes, and it usually makes sense to sequence them together. A new ADU or addition changes roof lines, creates new valleys, and affects drainage across the whole property. We handle the roof and the addition under one contract, which removes the coordination gap you’d have with separate subs. For a bundled scope, call (833) 589-8103 for a free estimate.
