Owens Corning Construction in Lexington Hills, CA | San Mateo Construction
We provide independent Owens Corning service across Lexington Hills and nearby communities, including Los Gatos Owens Corning service, installing and repairing Oakridge, Duration, and other Owens Corning roofing systems without any manufacturer affiliation. What makes our work different here is that we read the county’s fire-safe and septic plan review requirements before we spec the roof, because in Lexington Hills you can nail every shingle correctly and still fail your permit over a site plan issue. If you’re dealing with storm damage or planning a re-roof, call (855) 901-7266 and we’ll tell you exactly what we’re seeing on your roof.
Why Lexington Hills Residents Choose Us for Owens Corning Service
San Mateo Construction carries Owens Corning shingles, underlayment, and insulation because the brand has published installation specs we can follow on steep mountain pitches, and because we’ve torn off enough failed installations to know where the system works and where shortcuts show up first. Noel Carrington, our owner, grew up pouring concrete footings with his father in San Mateo and spent three decades on residential and light commercial jobs across the county. That background means we don’t guess at valley flashing or deck prep. We follow the Owens Corning installation manual and then layer in what Lexington Hills fire code actually demands. Independent service means we repair what’s repairable and recommend replacement only when granule loss, deck damage, or widespread tab failure makes patching a waste of your money. View our broader Owens Corning sales & service work and you’ll see the same approach: brand-correct materials, honest repair-versus-replace guidance, and no pressure toward a full tear-off that isn’t warranted.

Common Owens Corning Construction Problems We Solve in Lexington Hills
- Granule loss and blown sealant strips on south-facing roofs. Hot, dry summers bake Oakridge and Duration shingles on exposed slopes, and once the self-seal adhesive gives way, wind-driven rain finds exposed nail heads. We re-seal or replace affected tabs before leaks become deck rot.
- Storm-driven limb punctures. Winter storms drop oak and redwood branches onto roofs throughout Lexington Hills. Debris punctures crack shingle mats and shear the adhesive strip. We chase the leak path from the impact point to the eave, because water never travels straight.
- Valley and underlayment failures on low-slope transitions. Many owner-built cabins here were never detailed to Owens Corning’s published valley and eave requirements. We rebuild valleys with ice-and-water membrane and proper flashing so water sheets off instead of pooling.
- Compressed Fiberglas batts in shallow crawlspaces and knee walls. Owens Corning PINK insulation loses R-value when squeezed into pier-and-beam spaces. We check compression and moisture saturation, which is common where slopes stay wet through winter.
- Crumbling Foamular rigid board on exterior walls. Where moisture wicks up from saturated hillsides, aged Foamular breaks down. We replace it with properly fastened rigid insulation and address the drainage so the new board lasts.
Owens Corning Service in Lexington Hills: What Local Conditions Mean for Your Equipment
Lexington Hills sits in a high-fire-severity zone, which means every re-roof here is a Class A fire-rated assembly decision, not just a shingle swap. The county plan review requires your site plan to show both the 100-foot defensible-space zone and the septic system’s approved expansion area. Get the roof detail right and you can still lose the permit over clearance or a septic line drawn wrong. We’ve seen it happen. That’s why we start by walking the property and reading the existing permit record before we quote shingles. On a redwood-sided cabin off Old Santa Cruz Highway, we stripped storm-damaged Oakridge shingles and found punctured underlayment at a valley and a deck softened by years of trapped moisture. We rebuilt the valley with new ice-and-water membrane before re-roofing to a Class A assembly. Because the private road blocked our material truck, we staged shingle bundles at the pullout and carried them up. Then we cleared defensible-space brush so the finished roof met county fire-safe review. That’s how Owens Corning work actually gets done in Lexington Hills service area terrain: plan review, access logistics, and fire code all shape the job before the first bundle lands.
Owens Corning Models & Products We Service in Lexington Hills
We install and repair Oakridge and Oakridge Pro architectural shingles, plus Duration and Duration Designer (TruDefinition) lines for homeowners who want deeper shadow lines and better wind performance on exposed slopes. Older cabins still wearing Supreme or WeatherGuard 3-Tab shingles come up often, and we can match or replace those as needed. For insulation, we work with Owens Corning PINK Fiberglas batts and Foamular rigid board. When a repair calls for shingles, we match Owens Corning product to the same system so warranty-relevant details stay intact. We use quality aftermarket flashing and fasteners where they outperform the OEM piece, and we keep common Owens Corning accessories on hand for faster Lexington Hills turnaround.

FAQs – Owens Corning Construction in Lexington Hills
No. San Mateo Construction is an independent contractor that installs and repairs Owens Corning products. We follow the brand’s published installation specs but we’re not manufacturer-affiliated, which means our repair recommendations aren’t tied to warranty-claim quotas or replacement targets.
We match Owens Corning shingles, underlayment, and accessories to the same system so warranty-relevant details stay intact. Where aftermarket flashing or fasteners perform better than the OEM piece, we use those and tell you why. The goal is a roof that holds up, not a parts invoice that matches a catalog.
A typical repair takes a day or less once materials are on site. Full replacements run three to five working days, depending on access, deck repairs, and fire-rated assembly requirements. Narrow private roads can add staging time. Call (855) 901-7266 and we’ll give you a realistic schedule for your specific roof.
That depends on moisture exposure, compression, and whether the existing R-value meets current code for your assembly. On Lexington Hills hillsides, we often find batts compressed in shallow crawlspaces or rigid board crumbling where water wicks up from slopes. We test and measure before we tell you to keep or replace it.
Roof replacement generally runs $8,000 to $20,000 here, with repair work between $400 and $1,800 depending on the damage. Access issues, deck rot, and Class A fire-rated requirements all move the number. Call (855) 901-7266 for a written quote. Estimates are free.
