GAF Construction in Lompico, CA | Milpitas Construction
We provide our GAF services including independent roofing installation, repair, and replacement across Lompico, CA. We’re not a manufacturer-authorized dealer, and we’re upfront about that. What separates our GAF work here is simple: we understand how these roofs hold up on steep, wooded canyon lots where fog drip never really stops and material delivery requires a plan before the first shingle comes off. Call (877) 752-4194 for a free estimate.
GAF makes solid roofing systems. Timberline HDZ, AS II, UHDZ, EverGuard TPO for low-slope sections. But the best shingle in the world fails early if the underlayment’s wrong for the microclimate or the ventilation can’t move moisture out of a shaded attic. Lompico tests every layer of a roof system, all year. We spec each layer for what actually happens on Lompico Road, West Drive, and the side canyons off them.
Why Lompico Residents Choose Us for GAF Service
Ken Stafford, our owner, grew up around Milpitas and built his trade in the Bay Area’s soil shifts and seismic quirks. He got his foundation in construction technology at Evergreen Valley College, and the principle stuck with him: build it right the first time, the Bay Area doesn’t give you a free pass on shortcuts. That’s the standard we bring to every GAF roof in Lompico.
We’re a full-scope general contractor, which changes the conversation on any roofing job. The same company managing your roof can handle the siding, deck, drainage, and hardscaping around it. That single-contract accountability matters in Lompico, where a roof leak at the eave often connects directly to a gutter overflow problem and a drainage issue at the foundation. We’re not passing blame between trades because there’s only one team in the room.
We use GAF OEM shingles, underlayments, and ventilation components. That protects the manufacturer’s warranty. It also means repairs blend with the existing roof rather than leaving a patchwork that looks like an afterthought. And we stock the most common GAF materials for fast turnaround on Lompico projects.

Common GAF Construction Problems We Solve in Lompico
- Moss and algae on shaded slopes. Lompico sits in the redwood belt, where north-facing roof planes get almost no direct sun between November and April. Moss roots into the shingle mat, lifting granules and trapping moisture against the asphalt. We see this most on sections under redwood canopy or overhanging oak. We remove the growth and address the moisture pattern so it doesn’t return in two years.
- Wind uplift at ridge and rake edges. Canyon gusts funnel through the Lompico Creek drainage and hit rooflines from odd angles. Shingle tabs lift at the ridge and rake, exposing underlayment, and once one tab catches wind, the tear-off spreads quickly. We re-secure or replace the affected courses and check nailing patterns across the whole plane.
- Rot at eaves and fascia. Heavy winter rain plus gutters overwhelmed by redwood needles and oak litter means water spills over the gutter edge and wicks into the fascia, then into the roof sheathing. By the time staining shows inside, the rot’s usually deeper than the visible damage. We open it up, cut out the soft wood, and rebuild before re-hanging gutters with proper slope.
- Underlayment failure under prolonged fog drip. Standard felt underlayments give up after years of fog that never dries. The result is leaks at pipe penetrations, valleys, and anywhere the roof plane changes. For Lompico, we spec higher-grade synthetic underlayment or ice-and-water shield at eaves and valleys, because the fog drip is as much of a threat as the rain.
- Skip sheathing soft spots. Many 1960s and 1970s Lompico cabins were built with spaced board sheathing, not plywood. Between those gaps, underlayment has nothing behind it except air, and decades of moisture leave soft spots that a new shingle layer can’t fix. We re-deck where needed before laying any new GAF system.
GAF Service in Lompico: What Local Conditions Mean for Your Roof
Here’s the detail nobody tells you until the first delivery attempt: most Lompico homes sit below narrow, winding private roads where a standard roofing delivery truck cannot turn around or reach the property line. We’ve had supplier trucks refuse to back down West Drive. So we stage materials for our Ben Lomond GAF service at a wider turnout up on Lompico Road and shuttle them down by pickup, load by load. It adds time and a little cost. It’s also unavoidable on nearly every canyon lot here. A flatland Santa Cruz contractor might not plan for that until the truck’s already stuck, and then you’re paying for a crane or waiting a week. We plan for it before you sign anything, because we’ve done enough Lompico roofs to know the road is part of the job.
GAF Models & Products We Service in Lompico
We install and repair the full GAF residential line through our Brookdale GAF service: Timberline HDZ, Timberline AS II, Timberline UHDZ, plus EverGuard TPO for any low-slope porch, carport, or addition roof. We use OEM GAF shingles, underlayments, and ventilation components on every job, whether it’s a two-square repair or a full replacement. That keeps the system warranty intact and makes future repairs easier to match.
We keep the most common GAF colors and accessory components in local supply for Lompico projects, and we can source any Timberline line within a few days. If your roof’s older and the exact color is discontinued, we’ll tell you straight and help you pick a close match or plan for a phased replacement.

AfterGAF Service Pricing in Lompico
| Service | Price Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Gutters & Accessories | $250 – $700 |
Roof replacement cost depends on roof size, pitch, access, and whether re-decking or structural repair is needed. Steep canyon lots and shuttled material delivery add cost compared to a flatland job. Repair pricing depends on what’s failing: a single missing shingle is at the low end; rot at eaves, underlayment replacement, or re-flashing penetrations pushes toward the higher end. Every estimate is a written line-item quote, and we don’t change the number after work starts unless the structure reveals something we couldn’t see from the surface. Call (877) 752-4194 to schedule your free estimate.

FAQs – GAF Construction in Lompico
It does. Homes in Lompico’s wildland-urban interface need roofing that meets CalFire defensible-space standards, including a class A fire rating and a roof design that doesn’t trap embers at the eaves or ridge. Timberline HDZ and UHDZ shingles carry a Class A fire rating, but the full system matters: the underlayment, the edge detailing, and whether the attic vents are ember-resistant. We’ll spec the whole system for fire code as well as rain and fog, because the roof is the first line of defense for both. Call (877) 752-4194 to talk through what your specific lot requires.
We stage materials at a wider turnout or accessible point on Lompico Road, then shuttle everything to the property by pickup. This is the standard plan for most canyon lots in Lompico, and we build the extra time and cost into the estimate up front. We don’t promise delivery dates we can’t keep and we don’t leave a truck blocking your neighbor’s only way out.
Can you repair my GAF roof if it has moss damage, or do I need a full replacement?
That depends on how deep the moss has gone. If it’s surface growth and the shingles still have granule adhesion, we remove it, treat the affected area, and repair any lifted tabs or exposed underlayment. If the moss has penetrated the shingle mat and the sheathing underneath is soft, a targeted repair won’t stop the rot from spreading, and we’ll tell you that honestly. We’d rather replace a section now than charge you for a repair that fails in eighteen months. Call (877) 752-4194 and we’ll take a look.
Ridge and eave vents are the baseline, and most older Lompico cabins don’t have enough of either. We also check that intake vents aren’t buried under moss or blocked by redwood needles. A ridge vent paired with continuous soffit or eave intake moves moisture out of the attic before it condenses on the sheathing. On our West Drive project, the homeowner told us the attic stayed noticeably drier the next winter after we added ridge and eave vents with the Timberline HDZ replacement.
We recommend a higher-grade synthetic underlayment for most Lompico roofs, plus ice-and-water shield at eaves, valleys, and around penetrations. Standard felt underlayment degrades under the kind of prolonged moisture this canyon produces, especially on shaded planes that never fully dry. The upgrade adds a small cost per square and makes a meaningful difference in how long your GAF system holds up.
