How It Works

Fire Detected. Sprinklers On. You Are Already Gone.

The whole point is that you do not have to be home. The system watches, decides, and acts on its own.

STEP 01

Satellite Detects Fire

Satellite monitoring spots wildfire activity within miles of your property. You get an alert on your phone.

STEP 02

Cameras Confirm Threat

On-property cameras verify the fire is approaching your location. The system does not rely on a single data source.

STEP 03

Sprinklers Activate

Roof, eave, and perimeter sprinklers turn on automatically. Water wets every surface. Embers wash off before they ignite.

After you evacuate: The system keeps running for hours on your home's backup power (generator or Powerwall) and Starlink satellite connectivity. Monitor everything from your phone.

The Technology Behind FireRoofs

FireRoofs is an automated exterior wildfire sprinkler system that combines satellite wildfire detection (via NIFC and WFIGS data feeds), an on-property sensor array measuring air quality index, gas concentration, temperature, humidity, barometric pressure, and altitude, on-site camera verification, and a mobile app with zone-level valve controls. The system assigns threat levels based on aggregated sensor data and satellite proximity. At configurable threat thresholds, the system autonomously activates roof, eave, and perimeter sprinkler zones without human intervention. Homeowners retain full manual override through the FireRoofs app, which displays sensor dashboards, active wildfire maps, live camera feeds, and individual valve toggles for Water Master, Foam Master, Roof-Front, Roof-Rear, Eaves, Perimeter, and Pool Pump zones. Every installation includes backup power (generator or Tesla Powerwall) and Starlink satellite internet to maintain full system operation when grid power and terrestrial internet fail during a wildfire event.

The Evidence Is Not Theoretical

Real fires. Real homes. Real survival data.

Ham Lake Fire, 2007

100% of homes with exterior sprinkler systems, combined with defensible space and home hardening, survived. Multiple unprotected neighboring homes were destroyed. The most cited case study in the wildfire sprinkler industry.

IBHS Research

The Insurance Institute for Business and Home Safety has documented that pre-wetting roof surfaces significantly raises the ignition threshold. Wet materials need far more heat to catch fire.

Ember Wash Effect

Continuous water flow physically washes airborne embers off the roof before they accumulate in valleys, gutters, and other collection points where spot fires typically start.

Insurance Impact

California CDI Regulation 2644.9 (the "Safer from Wildfires" framework) requires insurance carriers to recognize wildfire mitigation when setting premiums and making renewal decisions. A professionally installed roof sprinkler system addresses one of the strongest mitigation categories in the regulation.

FireRoofs provides carrier-ready documentation including installation photos, system specifications, and ongoing maintenance records that your insurance broker can submit directly to your carrier.

Roof Sprinkler System FAQ

A roof sprinkler system is a set of sprinkler heads mounted along the roof ridge, eaves, and perimeter of a home. When activated, the sprinklers wet the roof, walls, and surrounding vegetation to reduce the chance of ignition from radiant heat and airborne embers during a wildfire. Professional systems activate automatically using satellite monitoring and on-property cameras. DIY versions require manual activation before you evacuate.

A basic professional roof sprinkler system costs $10,000 to $25,000 installed for a typical single-family home. Full perimeter systems with dual detection run $25,000 to $50,000. Premium systems with Class A foam injection start around $50,000 and go up for large estates. DIY sprinkler kits cost $200 to $1,000 but require manual activation and offer limited coverage. FireRoofs provides free on-site evaluations with detailed pricing for your specific property.

Yes. In the 2007 Ham Lake Fire, 100% of homes with exterior sprinklers combined with defensible space and home hardening survived while neighboring unprotected homes were destroyed. The science is clear. Pre-wetting the roof surface raises the ignition threshold. Wet vegetation in the defensible space zone absorbs radiant heat instead of igniting. Continuous water flow washes away landing embers before they can establish combustion. IBHS research supports all three of these mechanisms.

Interior fire sprinklers (the kind required in new construction) activate after fire is already burning inside your home. They protect occupants and slow interior fire spread. Roof sprinkler systems are exterior. They activate before fire reaches your home and prevent ignition from the outside. The two systems serve completely different purposes. During a wildfire, interior sprinklers do nothing because the threat comes from outside.

DIY sprinkler kits exist, but they have serious limitations. You have to be home to turn them on. Water pressure from a single garden hose drops significantly with multiple sprinkler heads. Coverage is uneven. There is no detection system to alert you, and no way to activate remotely after evacuating. Professional automated systems solve all of these problems with dedicated water lines, engineered head placement, satellite detection, and autonomous activation.

A typical system uses 15 to 40 gallons per minute depending on the number of zones active. A full 2-hour activation cycle uses roughly 1,800 to 4,800 gallons. Many professional installations include dedicated water storage tanks (2,500 to 10,000 gallons) to ensure supply even if municipal water pressure drops during a large-scale wildfire event. FireRoofs designs water storage into every system where municipal supply may be unreliable.

California CDI Regulation 2644.9 (the "Safer from Wildfires" framework) requires insurance carriers to recognize wildfire mitigation measures when setting premiums. A professionally installed and documented roof sprinkler system addresses multiple categories in the regulation. FireRoofs provides carrier-ready documentation including installation photos, system specifications, and maintenance records for every installation.

FireRoofs App and Technology FAQ

How the sensor network, automated controls, and mobile app work together to defend your home.

The FireRoofs app is the command center for your exterior wildfire defense system. It connects to on-property sensors measuring air quality, gas levels, temperature, humidity, and pressure. It displays active wildfire locations from the National Interagency Fire Center (NIFC) WFIGS data feed. It lets you arm or disarm sprinkler zones, toggle individual valves (roof-front, roof-rear, eaves, perimeter, foam master, pool pump), view live camera feeds, and review historical sensor data logs. The app works from anywhere with an internet connection.

The system uses a multi-layer detection approach. Satellite monitoring from NIFC and WFIGS tracks active fire incidents near your property. On-property hardware sensors detect changes in air quality, gas concentration, and temperature that indicate fire proximity. On-site cameras provide visual confirmation. The app aggregates all three data sources and assigns a threat level. At higher threat levels, the system initiates an automatic activation countdown that the homeowner can override from the app.

Yes. The FireRoofs app provides full manual override from anywhere. You can toggle the Water Master Valve, Foam Master Valve, and individual zone valves (Roof-Front, Roof-Rear, Eaves, Perimeter, Pool Pump) independently. You can also trigger a full-system activation or shut down specific zones. The system is designed to operate autonomously when threat levels are high, but manual control is always available.

The FireRoofs sensor array includes an air quality index (AQI) sensor, gas sensor for combustion byproducts, temperature sensor, barometric pressure sensor, humidity sensor, and altitude sensor. The sensor dashboard in the app displays all readings in real time with gauges and historical trend data. These sensors feed into the automated threat detection engine that determines when to activate the sprinkler system.

Yes. Every FireRoofs installation includes backup power (generator or Tesla Powerwall) and Starlink satellite internet connectivity. When grid power and terrestrial internet go down during a wildfire, the system continues operating on backup power and maintains connectivity through Starlink. You can still monitor and control the system through the app using the satellite uplink.

The app displays a live wildfire map sourced from the Wildland Fire Interagency Geospatial Services (WFIGS) and the National Interagency Fire Center (NIFC). It shows the location, size, and status of active fire incidents near your property. The map updates regularly with data from federal, state, and local fire agencies. This gives you situational awareness about fire activity in your area without relying on news broadcasts or social media.
