Homes are lost in wildland fires when they are ignited in one of three ways:
- The most common is burning embers falling upon flammable roofs (e.g. wood shake or shingle).
- Falling or wind blown embers easily kindle leaves or needles on roofs, in rain gutters, or under decks and porches.
- Homes are also lost through either direct flame contact, concentration of heat under structures, decks, alcoves and eaves. Finally, fires are ignited through radiation from burning vegetation.
