FAQ
What is the single biggest mistake homeowners make on this decision?
Buying hardware before Zone 0, vents, and a water budget are honest.
Does this article replace a site inspection?
No. Wildfire Compare Pilot guides frame questions; a licensed installer or your broker still has to apply them to your roof, slope, and policy form.
Should I automate before I harden?
Usually harden and clear Zone 0 first. Automation amplifies a ready shell; it rarely rescues an ember-friendly one.
