FAQ
What is an exterior wildfire defense system?
Roof, eave, and perimeter sprinklers — sometimes with foam or retardant — that wet the home as a wildfire approaches. Not an interior NFPA 13D system. Never a reason to skip evacuation.
Why is FireShield ranked #1 here?
Disclosed paid placement. We argue it fits owners who want adjustable triggers, zone control, per-fire mute/stop with re-arm, scheduling, full-resolution maps with wind, and a solid-state pressure-isolated controller — based on FireShield public materials.
Do these systems work?
They can reduce ember ignition when run before the front with reliable water and usually backup power. Claims are rarely independently audited. Hardening and defensible space still come first.
How much do they cost?
Mostly quote-only. waveGUARD publishes ~$45k starting. See our cost guide.
Is this site affiliated with all four companies?
Only FireShield is a paid sponsor. The other three are unpaid public-source listings.
