Autonomous Wildfire Sprinklers
Heat and ember sensors start a roof and perimeter spray of water mixed with biodegradable Class A retardant. The system runs off the grid from your pool or a dedicated tank, whether or not anyone is home.
[ 01 ]The problem
Why this layer matters.
Firefighters can't be at every house during a wind-driven fire, and most homes are lost hours after the front passes, to embers no one is there to put out. An exterior sprinkler system keeps the roof, eaves and the ground around the house wet through the worst of the ember storm, then keeps working while you are evacuated.
[ 02 ]How we install it
Specified by firefighters. Built by craftsmen.
Every install follows the same four steps and ends with documentation for your insurer.
Site design
A retired fire officer maps roof planes, prevailing wind and water supply, then sizes heads and pump for your home.
Install
Copper supply lines and brass heads go in out of sight. No plastic anywhere radiant heat can reach.
Water and power
We connect to your pool or a dedicated 5,000 to 30,000 gallon tank with an independent pump and power.
Commission
We test sensors, app control and coverage, then log the system for your insurer.

[ 04 ]Planning your project
What shapes your autonomous sprinklers plan.
Every home is different. These are the factors a Wetline specialist looks at during your free assessment.
Roof size and shape
More roof planes, ridgelines and valleys mean more heads and longer supply runs.
Water source
A pool can often supply the system. Homes without one need a dedicated tank, sized for how long the system must run.
Power and pump
An independent pump and power source keep the system working when utilities are cut.
Terrain and exposure
Homes on ridgelines or above canyons often need perimeter heads that wet the slope below the house.

Exterior Wildfire Sprinklers: What to Know Before You Install
Rooftop wildfire sprinklers can protect a home through an ember storm, but only if they're designed right. Water supply, power and hardware are what separate real systems from garden hoses.

[ ? ]FAQ
Autonomous sprinklers questions.
Still deciding? Call or text 310-569-4523.
Will the sprinklers work in a power outage?
Yes. Systems run on their own pump and power and draw from a pool or tank, so they keep working when utilities are cut.
Do the sprinklers waste water?
The retardant mix cools surfaces far faster than plain water and extends usable water by roughly half, so a tank lasts longer during an event.
Can the heads be hidden?
Yes. We design every layout around the architecture, and most heads sit below rooflines or behind parapets.
