Redwood lots off Highway 17
Many homes started as cabins and weekend houses and grew with additions over the decades. Roofs are commonly a patchwork of pitches and materials, shaded by redwoods, oaks and madrones. Roads such as Old Santa Cruz Highway, Black Road and Summit Road are narrow and winding, which shapes how and when materials arrive.
- Constant shade and moss: roofs under redwoods stay damp through winter, growing moss that lifts shingles and holds water.
- Needle-packed gutters: redwood needles fill gutters and valleys continuously, not just in fall.
- Patchwork additions: each change in pitch or material is a joint that can leak under mountain rainfall.
- Decks and low-slope sections: many cabins have flat roofs over decks or rooms that pond in heavy storms.

Heavier mountain rain and storm damage
Storms that bring steady rain to the valley can bring several times as much to the ridges along Highway 17. The atmospheric-river series of winter 2022 to 2023 brought down trees across the Santa Cruz Mountains. When a limb or tree damages a roof, our emergency roof repair service tarps and secures it, and the office can assemble photos and notes your insurance adjuster will ask for. Gutters sized for valley rainfall often overflow here, so we check capacity and downspout routing on every visit.
The ground matters as much as the weather. The epicenter of the 1989 Loma Prieta earthquake lay in these same mountains, south of Highway 17, and older stone and brick chimneys on cabins here often show the repairs. Saturated hillsides also slip during long storms, and a slope that shifts under a deck or an addition can open the joint where that roof meets the house, so we check those transitions after every major wet spell.
Fire hazard rules for Santa Cruz Mountains roofs
CAL FIRE maps much of Lexington Hills as a Fire Hazard Severity Zone, where Chapter 7A of the California Building Code expects a Class A rated roof and vents that stop embers. Untreated wood shake, still found on some older cabins, does not qualify. We install Class A composition, metal and synthetic shake, and replace standard vents with ember-resistant attic vents.

Lexington Reservoir, Old Santa Cruz Highway and the four neighborhoods
The Lexington Hills census-designated place had 2,492 residents at the 2020 Census, spread across Redwood Estates, Chemeketa Park, Holy City and Aldercroft Heights. Lexington Reservoir, formed when Lexington Dam was completed on Los Gatos Creek in 1952, marks the bottom of the community, and Lexington Reservoir County Park surrounds much of its shoreline. Holy City began as a religious colony around 1919; its scattered buildings along Old Santa Cruz Highway are a reminder of how old some of the structures up here are.
Highway 17 carries us up from Campbell, then Old Santa Cruz Highway, Black Road and Summit Road branch off to the ridges. Children in much of the area attend the Loma Prieta Joint Union School District, with its campuses up on Summit Road. Because the County governs these ridges, unincorporated parcels here fall in the Silicon Valley Clean Energy service area, while many homes depend on small water systems or wells, which makes a dry, intact roof over storage tanks and pump houses worth a look too.

From Campbell up the hill: inspection and County permit
No city government covers these ridges, which leaves reroof permitting to the County's land-use and building staff. We look at the roof, gutters and access, then send photos and a free written estimate. Narrow mountain roads affect delivery and dumpster placement, so we plan logistics before the job starts. We have no Lexington Hills projects or local reviews to show; what we offer is a short drive, clear documentation and daily cleanup.
