Three levels of protection — from essential annual cleaning to full rooftop sprinklers. Choose what fits your home's exposure and your insurer's requirements.
Hollister sits in the heart of San Benito County, surrounded by Diablo Range terrain on three sides. The dry grasslands and chaparral of the Gabilan Range and the hills above the Salinas Valley represent some of the most fire-prone landscapes in Central California. ORS Clean removes the fuel and installs the barriers before fire season.
Every level includes before-and-after photo documentation you can submit to your insurer. Choose based on your home's location, your tree coverage, and your peace of mind.
The essential annual clean every Hollister home should complete before fire season — removes the two biggest ignition risks from your property in a single visit.
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.
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.
Hollister occupies one of the more fire-exposed positions of any city ORS Clean serves. San Benito County is almost entirely surrounded by the Diablo Range — a mountain range with extensive fire history, dry summer conditions, and significant chaparral and grassland fuel loads. The hills above Hollister carry Cal Fire Very High Fire Hazard Severity Zone designation, and the Hollister Hills SVRA to the south borders residential development directly. Cienega Road properties and homes along the eastern and southern edges of the city face the most direct WUI exposure. Dry seasonal winds from the east push fire-generated embers into the valley; during extreme events, the terrain funneling effect through Pacheco Pass accelerates wind speeds and ember travel distance significantly. California insurers have increased scrutiny of San Benito County properties over the past three years as fire risk models have been updated to reflect the drought-driven fuel load increases across the Diablo Range. Annual Level 1 pre-season maintenance with photo documentation is the minimum every Hollister homeowner should complete.
Properties along Cienega Road and south of downtown border Hollister Hills SVRA and open Diablo Range terrain directly. These areas have the highest direct ember exposure during wind-driven events. Level 2 or Level 3 strongly recommended.
The eastern edge of Hollister rises into fire-prone chaparral and grassland. Homes here are within close proximity to terrain that can carry fire rapidly during dry easterly wind events.
Mid-elevation area within ember travel range of the surrounding hills. Level 1 annual cleaning with photo documentation is the appropriate minimum, especially as insurer scrutiny in San Benito County increases.
Ridgemark golf community and west-side neighborhoods face open terrain exposure, particularly toward the hills north and south of the city. Level 1 minimum; Level 2 for homes with significant tree canopy.
Understanding how wildfires actually destroy Hollister homes changes how you prepare.
The hills above Hollister on three sides carry extensive dry chaparral and grassland fuel loads. Fires in this terrain — which have occurred repeatedly — generate immediate ember showers that can reach residential neighborhoods within minutes.
Seasonal easterly winds and Pacheco Pass wind channeling push embers into the Hollister valley from multiple directions. Embers travel 1–2 miles in typical conditions — further during the high-wind events that this terrain is known for.
✓ Level 1: Removes the fuel embers land onDry 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.
✓ Level 2: Mesh blocks accumulation after cleaningRooftop 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 Hollister homeowner can achieve.
✓ Level 3: Active water defense at the rooflineCalifornia insurers have increased scrutiny of San Benito County properties as fire risk models have been updated to reflect the Diablo Range fuel load increases driven by drought. Documented proof of roof and exterior maintenance is increasingly required for policy renewal. ORS Clean provides before-and-after photo documentation on every job you can forward directly to your insurance agent.
Every level includes full photo documentation. We email you a complete before-and-after report you can forward directly to your insurance agent. Multiple Hollister customers have used this to retain or restore coverage.
"I received a letter from my home owners insurance that I was being canceled due to moss and algae on my roof. Matt was great to work with. He came out the next day to site walk it and determine pricing. I received a quote that evening, and we were scheduled within 3 days. Matt and his crew showed up as scheduled, cleaned my roof and cleaned my solar panels. Matt sent me photos of the cleaned roof to submit to my insurance company. I highly recommend Matt and his crew."
Homes along Cienega Road and south of downtown, where properties border the Hollister Hills SVRA and open Diablo Range terrain, face the highest direct exposure. East Hollister foothill properties are also high-risk. Downtown and Ridgemark areas are within ember travel range of the surrounding hills during significant wind events. The Pacheco Pass wind corridor can accelerate ember travel across the valley during extreme events.
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 Hollister and South Bay customers have used this documentation to retain or restore coverage after receiving non-renewal notices.
Twice per year is ideal for Hollister 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 Hollister — near downtown, Blossom Hill, and Vasona Park — are within ember cast range of the surrounding hills during Diablo wind events. All of Hollister zip codes 95023 and 95032 carry elevated insurer scrutiny.
