Exterior Sprinkler Systems
Built for Wildfire
Automated exterior sprinkler systems that activate before fire reaches your property. Dual wildfire detection triggers roof, eave, and perimeter zones to lay down a continuous water barrier across every vulnerable surface. Fully automated. No buttons. No one needs to be home.

Exterior Sprinklers Protect Your Home.
Most residential sprinkler systems are designed for interior fires. They activate after flames are already inside. That approach does nothing when wildfire rolls through a neighborhood at 2 AM and your family has already evacuated.
Exterior sprinkler systems work differently. They drench the roof, eaves, siding, decks, and vegetation before fire arrives. The goal is not suppression. The goal is keeping every exterior surface wet enough that embers can't catch.
FireRoofs builds automated exterior sprinkler systems specifically for homes in California's wildland-urban interface. Every system is custom-designed around the property's unique fire exposure: slope, prevailing winds, vegetation density, and structure layout.
In a wildfire and after a wildfire, the homes that make it through are the ones with wet exterior surfaces when embers arrive. That's what an exterior sprinkler system delivers.
How Automated Exterior Sprinklers Defend Your Property
Detect
Dual wildfire detection monitors threats at two levels. Regional satellite wildfire monitoring tracks fire activity across a 5-mile radius. On-property cameras with intelligent fire detection watch the immediate surroundings. Both feed into the automated threat protocol.
Alert
When a threat is confirmed, the system escalates through three response levels. You get real-time notifications through the FireRoofs app. The system does not wait for you to press a button. It moves.
Defend
Exterior sprinkler zones activate in sequence based on threat direction. Roof sprinklers throw water 20 feet past the roofline. Eave sprinklers protect the most vulnerable ignition points. Perimeter zones flood defensible space with continuous coverage. Optional Class A foam multiplies suppression coverage. Foam is 100% biodegradable, non-toxic to plants, pets, and wildlife, and rinses off through the sprinklers.

Designed for Homes in California's Wildfire Zones
FireRoofs exterior sprinkler systems are built for homeowners in the wildland-urban interface who face real fire exposure and can't get adequate insurance coverage.
If your home is in a Very High Fire Hazard Severity Zone, or you've been dropped by your carrier and pushed to the FAIR Plan, an automated exterior sprinkler system is one of the strongest risk-reduction measures available. Some insurance carriers recognize active fire defense systems when evaluating coverage.
We chose 21 communities, not 21 states. While other companies expand coast to coast, we went deeper into the Bay Area's fire corridors. 50+ years of local construction and irrigation expertise. Every system designed for the specific terrain, installed by a licensed California General Contractor.
What Installation Looks Like
Every system starts with a free on-site evaluation: water pressure testing, roof and eave inspection, Zone Zero walkthrough, and a full perimeter assessment. The evaluation takes 45 to 60 minutes. You'll have a proposal within one to three business days.
Installation runs 3 to 10 days of construction depending on property size and complexity, followed by 1 to 2 days of system commissioning and homeowner orientation. The entire system is exterior-mounted with copper piping throughout. No roof penetrations. No interior wall work.
Sprinkler Systems & App Control
Roof sprinklers, perimeter nozzles, eave coverage, and the FireRoofs mobile app that puts system control in your pocket.
Common Questions About Exterior Sprinkler Systems
How are exterior sprinkler systems different from interior fire sprinklers?
Interior sprinklers activate after fire is inside the structure. Exterior sprinkler systems drench the roof, eaves, and perimeter before fire arrives, keeping surfaces wet so embers and radiant heat can't start a fire.
Do I need to be home for the system to work?
No. The system activates automatically through dual wildfire detection. Satellite monitoring and on-property cameras detect threats and trigger the appropriate response level without anyone pressing a button.
What happens if I lose power during a wildfire?
The system relies on the homeowner's backup power source, typically a generator or Tesla Powerwall. We design every system with power continuity in mind during the evaluation.
How much water does an exterior sprinkler system use?
Flow rates range from 50 to 200+ GPM depending on the number of zones activated. Systems include automatic water source switchover between municipal supply, wells, tanks, or pools to maintain pressure and supply.
Can an exterior sprinkler system help with homeowners insurance?
Some insurance carriers recognize active fire defense systems when evaluating wildfire coverage eligibility. A professionally installed and documented exterior sprinkler system can strengthen a homeowner's position when applying for private coverage or supplementing FAIR Plan limits. Results vary by carrier and property.
