Things are Heating Up

Yes, the June gloom is officially gone as Southern California enters our true summer of extensive sunshine and hot temperatures.  Of course (especially here at the beach), it’s nothing like the recent heat wave which has gripped most of the south and central US.

But it’s not the temperatures I’m referring to in the title of this article.  I’m talking about fire season.  After the recent 1 million+ acres of wildfire in Arizona, including the biggest single wildfire in state history, communities everywhere need to be aware of proper home fire safety.  While most of the population in California doesn’t fall into a Very High Fire Area Severity Zone or a Wildland/Urban Interface Area and the the Code-required construction requirements that go with them, there are basic measures that we can all take on our property to protect it in the case of fire.

The basics of exterior home fire protection are simple:

1.  Defensible Space – ‘Defensible Space’ is defined by CAL FIRE as ‘the buffer you create between a building on your property and the grass, trees, shrubs or any wildland area that surround it’.  This means 30’ of clear area immediately surrounding the home, and in rural areas another 70’ of ‘reduced fuel’ area to give the house 100’ of defensible space.

2.  ‘Harden’ your home – Fires spread to and between structures primarily by burning embers carried by the wind.  ‘Hardening’ your home means using fire-resistant/non-combustible materials for the exterior finishes.  This will resist the ignition of your home in the event of a fire in the area.  The roof and its related elements are the most vulnerable surfaces and non-combustible materials such as clay tile, metal panels or fiberglass shingles are preferred over wood or conventional paper-backed asphalt shingles.

There are many other guidelines, tips and checklists available to help increase wildland fire safety.  Here is a nice, easy to navigate website with home wildfire safety measures from CAL FIRE.
