Home Hardening

What is Home Hardening?

Home hardening refers to the process of minimizing a home's vulnerability to wildfires by using noncombustible building materials and implementing measures to prevent embers from entering the home. It can be applied to new construction or for retrofitting an older home.

Why is Home Hardening Important?

Embers from wildfire can pose the greatest threat to a home. About 60-90% of home loss in wildfire events is a result due to embers. By replacing your homes exterior construction with more fire-resistant materials, your home has a better chance of surviving a wildfire.

How to Harden Your Home:

Roofs

  • Replace wood shake or shingle roof with Class A roof (asphalt shingles, tile or cement shingles, or metal panels).
