How to Ember-Resistant Vent Check

Burning embers can travel miles ahead of a wildfire front, and a single ember entering your attic or crawl space through a vent can ignite your home from the inside even if flames never reach your property. This inspection involves checking all exterior vents—attic gable vents, soffit vents, foundation vents, dryer vents, and exhaust vents—to ensure they have 1/8-inch or smaller mesh screening that blocks embers while still allowing necessary airflow. Upgrading vent screens is one of the most cost-effective wildfire protection improvements you can make.
