Owens Corning Construction in Lompico, CA | San Mateo Construction
Owens Corning roof work in Lompico means dealing with steep, shaded slopes, single-lane private roads, and Santa Cruz County’s WUI and septic review process. We’re San Mateo Construction, and we handle Owens Corning tear-offs, re-decks, and full replacements across the 95005 ZIP. If your roof is losing granules on the south slope or moss is eating the north side, call (855) 901-7266 for a free estimate. We know what Owens Corning products do in Lompico’s wet redwood canyons, because we’ve installed them here for years.
We’re an independent contractor, not an Owens Corning authorized installer. That means we recommend what holds up in your specific canyon, not what corporate marketing says you should buy. Our company runs full Owens Corning roofing scopes alongside kitchen remodels, window replacements, and ADU builds. We know the product, and we know Lompico.
Why Lompico Residents Choose Us for Owens Corning Service
Most roofing crews in the Santa Cruz Mountains know flat lots and normal driveways. Lompico is neither. Our trucks have navigated the hairpin turns off Lompico Road more times than we can count, and our crews know how to stage tear-off material on a slope without blocking the only lane in or out. That matters when your neighbor can’t get to work because a dump trailer is parked badly. We don’t work that way.
Noel Carrington, our owner, grew up in San Mateo County and spent years on residential jobs before building San Mateo Construction. He’s the one who tells our roofers to walk the site first and check where water actually moves before quoting a shingle job. In Lompico, that walk usually finds the same things: moss on north-facing planes, granule loss where the sun cooks the roof, and damp eaves under redwoods. We plan for all three before we touch a shingle.
We use genuine Owens Corning products, including WeatherGuard underlayment and Duration Series shingles. We stock common components locally so we don’t leave a Lompico roof half-open while we wait for a distributor. And when something’s not worth repairing, we tell you straight. Call us for Owens Corning sales & service guidance, and we’ll help you sort repair from replacement.

Common Owens Corning Construction Problems We Solve in Lompico
- Granule loss on south-facing slopes. Lompico’s topography puts many roofs at a steep angle to the afternoon sun. Over years of thermal cycling, Owens Corning shingles shed granules faster on those exposures. You’ll see bald patches and granules in the gutters. We inspect the underlying mat and let you know whether it’s time for isolated repair or full replacement.
- Wind uplift and edge blow-off on ridgelines. Canyon winds funnel hard through Lompico’s draws and exposed ridges. Shingles near eaves and gable edges take the brunt. We re-nail lifted tabs where the seal has failed, and on full replacements we upgrade starter shingles and fastening patterns along the windward edges.
- Moss and algae streaking on north-facing planes. Heavy winter rain plus redwood canopy shade means the north side of many Lompico roofs never dries out. Moss holds moisture against Owens Corning shingles and accelerates granule loss. We usually pair a moss treatment plan with new underlayment and better ventilation.
- Underlayment failure and deck rot at valleys and eaves. Redwood needles and branch litter pile up in valleys and trap water against the roof surface. Over a few wet winters, that rots the decking underneath. We find this on old Lompico cabins built before modern drip edge and valley details existed.
- Ventilation problems causing premature shingle aging. Steep, tree-covered roofs often have inadequate ridge and intake vents. Hot, damp attic air bakes shingles from underneath and feeds moss growth on top. We size ridge ventilation for the actual pitch and square footage.
Owens Corning Service in Lompico: What Local Conditions Mean for Your Roof
Lompico is unincorporated, off-the-grid-adjacent country in the Santa Cruz Mountains. There is no municipal water, no sewer line, and no city building department. Nearly every building permit goes through Santa Cruz County, and any roof replacement or structural repair that changes your building envelope can trigger well-yield and septic-capacity review before permits clear. That is a step flatland roofers never encounter. A simple re-roof is usually straightforward, but if you’re adding a dormer, changing roof pitch, or enclosing a deck while we’re up there, the county wants to know your well and septic can handle the change. We’ve helped homeowners off Lompico Road and along East Zayante work through that review. We know what the county asks for, and we plan the scope so you don’t get surprised mid-project.
Material deliveries also have to fit down narrow private roads with no turnaround. We schedule smaller trucks and staged deliveries when needed. That’s not something a crew from over the hill thinks about until they’re stuck. We think about it before we quote. If you’re planning Owens Corning work in this ZIP, start with the site constraints, then pick the shingle.
Owens Corning Models & Products We Service in Lompico
We work with the full Owens Corning residential line that makes sense in Lompico: Oakridge architectural shingles for balanced performance, Duration Series when wind and impact resistance matter on exposed slopes, and Supreme 3-tab when you want a simple, economical tear-off on a rental cabin. We pair every install with WeatherGuard underlayment and spec-after-ventilation that matches your attic.
Our parts approach is practical. We use genuine Owens Corning shingles, underlayments, and accessories for the weather-exposed layers because those matter. For ventilation and flashing, we choose aftermarket components when they outperform the OEM equivalents for a specific Lompico roof profile. We stock standard shingle colors and underlayment additives locally for faster turnaround. For unusual color matches or steep-pitch accessory orders, we pull from our Bay Area supplier network.

FAQs – Owens Corning Construction in Lompico
Yes. We’ve installed on steep slopes off Lompico Road and along the private drives that branch from it. We stage smaller deliveries and use crews trained for steep-pitch safety. Call (855) 901-7266 and describe your access, and we’ll tell you what the logistics look like before any contract is signed.
In most cases, no. A straight tear-off and re-shingle without structural changes usually clears permits without triggering well-yield or septic-capacity review through Santa Cruz County. If you’re altering the envelope, adding dormers, or enclosing deck space, the county may want your well and septic evaluated. We’ve managed both scenarios and can tell you early which one applies to you.
We usually recommend Oakridge or Duration architectural shingles paired with a moss treatment plan and better ventilation. No asphalt shingle is truly moss-proof on a shaded north face, but proper ventilation and periodic cleaning make a larger difference than switching models. We’ll spec the right combination for your lot. Call (855) 901-7266 for a roof evaluation.
Sometimes. If the existing shingle is a current production color, we can often match it closely enough for a repair. If the roof is older and heavily weathered, a full replacement may be the better call, since patching a faded roof inevitably shows. We’ll tell you straight which path makes sense on your Lompico house.
Yes. We respond to leak calls after heavy rain, especially when wind has lifted shingles or debris has damaged a valley. We’ll tarp and protect the roof quickly, then quote the permanent repair. Call (855) 901-7266 and we’ll get someone up there as soon as the road allows.
