WUI Zone — Los Gatos Hills
Three levels of protection — from essential annual cleaning to full rooftop sprinklers. Choose what fits your home's exposure and your insurer's requirements.
Los Gatos sits at the edge of Sierra Azul Open Space and the Lexington Reservoir watershed — two of the highest-fire-risk open space areas in Santa Clara County. ORS Clean removes the fuel and installs the barriers before fire season.
Fire season is here — most homes are ember-ready in one visit, booked within 48 hours.
Local Fire Risk
Los Gatos is classified by Cal Fire as one of the highest wildfire risk cities in Santa Clara County. Thousands of homes border Sierra Azul Open Space Preserve — more than 18,000 acres of chaparral, oak woodland, and grassland that form the city's eastern and southern boundary. Lexington Reservoir County Park and the surrounding watershed create a second open-space buffer to the south and west. Both areas have extensive WUI designation and a documented fire history that affects neighboring properties directly. The 2020 SCU Lightning Complex — one of the five largest fires in California history — burned terrain within miles of the city's eastern edge. Diablo wind events, the Bay Area's equivalent of Santa Ana winds, push dry, fast-moving air through the Santa Cruz Mountains passes and into the Los Gatos hills each fall, dramatically increasing ember cast speed and distance. Gutter and roof debris that would be a minor issue in most cities becomes a serious ignition risk when 50+ mph Diablo winds arrive. California insurers including State Farm have specifically cited roof condition and exterior maintenance as grounds for non-renewal in Los Gatos zip codes 95030 and 95032. Level 1 annual cleaning before dry season is the minimum every Los Gatos homeowner should have completed.
Homes along these corridors border Sierra Azul and Lexington Reservoir directly. Most properties here have WUI designation and face the most direct ember cast exposure during Diablo wind events. Level 2 or Level 3 strongly recommended.
Heavy oak and madrone canopy accelerates debris accumulation on roofs. Many homeowners in these hillside areas have received insurance non-renewal notices citing roof condition. Annual Level 1 minimum; Level 2 mesh strongly recommended with significant tree coverage.
Lower elevation doesn't mean lower risk. These neighborhoods are within ember cast range of the surrounding hills during significant wind events. Level 1 annual cleaning is appropriate, with insurance documentation particularly valuable given county-wide insurer scrutiny.
Wind tunnel effect through the Santa Cruz Mountains accelerates ember travel along this corridor. Properties adjacent to the highway and the open space on either side face elevated risk during fall Diablo wind events.
State Farm, Allstate, and other major California insurers have cited roof condition and exterior maintenance as grounds for non-renewal — specifically in Santa Clara County hillside communities including Los Gatos zip codes 95030 and 95032. Documented proof of cleaning is increasingly required before renewal. ORS Clean provides before-and-after photo reports on every job.
Every level includes full photo documentation. We email you a complete before-and-after report you can forward directly to your insurance agent. Multiple Los Gatos customers have used this to retain or restore coverage.
Understanding how wildfires actually destroy Los Gatos homes changes how you prepare.
Sierra Azul, Lexington Reservoir watershed, or the Diablo Range foothills — all adjacent to Los Gatos — have active fire history. A fire in these areas immediately generates an ember shower.
At 40–60 mph, Diablo wind events push embers up to a mile ahead of the fire front. Your home doesn't need to be next to the fire — it needs to be within the ember cast zone.
Dry oak leaves, madrone bark, and pine needles in gutters and on the roof catch immediately. Gutters act as a fuel channel along the entire roofline.
Rooftop sprinklers activated before or during a fire event keep the entire roof surface saturated. Combined with clean gutters and ember mesh, this is the highest level of passive protection a Los Gatos homeowner can achieve.

Three clear levels — from the annual ember-season minimum to a complete active-defense system. Not sure which fits? Get a free assessment.
The essential annual clean every Los Gatos home should complete before fire season — removes the two biggest ignition risks from your property in a single visit.
Best for All Los Gatos homes — the annual minimum before dry season
Everything in Level 1, plus physical ember barrier installation on attic vents — sealing the most common entry point embers use to ignite a home from the inside.
Best for Homes near open space, heavily treed lots, hillside properties
The complete protection system for homes in or directly adjacent to WUI zones — combines all cleaning and mesh protection with an active water defense system.
Best for WUI-adjacent homes, Black Road, Bear Creek Road, Sierra Azul boundary
Los Gatos Fire Risk
Few places in the valley are more exposed than the Los Gatos hills. The homes above town — the Santa Cruz Mountains side, Chemeketa Park, the Kennedy and Shannon road areas — sit in dense redwood, oak, and chaparral, on steep lots the fire history of the range takes seriously. Embers riding the offshore winds over the ridge are the real threat, landing in needle-choked gutters and under wood decks.
Protecting a Los Gatos hillside home starts with removing the fuel right on the house: needles off the roof, debris out of the gutters and valleys, nothing dry against the walls. For these exposed properties we install and maintain rooftop sprinkler systems that can soak the roof, eaves, and deck when a red-flag warning hits and minutes matter.

Common questions
Very serious for many properties. Thousands of Los Gatos homes border Sierra Azul Open Space, Lexington Reservoir, and Diablo Range foothills — all WUI zones designated by Cal Fire. The 2020 SCU Lightning Complex burned terrain within miles of the city's eastern boundary. Diablo wind events push embers from open space fires directly into Los Gatos neighborhoods in fall. Insurance companies including State Farm have cited roof condition as grounds for non-renewal in Los Gatos zip codes 95030 and 95032. Level 1 annual cleaning is the minimum every Los Gatos home should complete before dry season.
Level 1 (Ember Ready): gutter cleaning plus full removal of all dry debris from the roof surface. Level 2 (Ember Defended): everything in Level 1 plus ember barrier protection installed on attic vents — the most common entry point for embers to ignite a home from within. Level 3 (Maximum Defense): everything in Level 1 and 2 plus rooftop sprinkler installation, with optional under-eave misters for additional protection at the eave line. All levels include before-and-after photo documentation.
Yes, in many cases. California insurers in high fire risk zones increasingly require documented evidence of roof and exterior maintenance as a condition of coverage or renewal. ORS Clean provides a before-and-after photo report on every job that you can submit directly to your insurance agent. Multiple Los Gatos and South Bay customers have used this documentation to retain or restore coverage after receiving non-renewal notices.
Twice per year is ideal for Los Gatos hillside homes — once in spring (April–May) to clear winter oak and madrone debris before dry season, and once in late fall (October–November) after leaf drop. The fall window is especially important for homes with heavy tree coverage. At minimum, a pre-summer clean before California's fire season begins significantly reduces risk. We can set you up on a recurring schedule.
Homes along Black Road, Bear Creek Road, Kennedy Road, and the Sierra Azul Open Space boundary face the highest direct exposure. Lexington Hills and the Highway 17 corridor properties border designated WUI zones. Even homes in lower-elevation Los Gatos — near downtown, Blossom Hill, and Vasona Park — are within ember cast range of the surrounding hills during Diablo wind events. All of Los Gatos zip codes 95030 and 95032 carry elevated insurer scrutiny.
