In the driest year in recorded state history, California is bracing for a devastating wildfire season - one that is starting about five months early, according to Blomberg News ("Early California Wildfires Jeopardize Homes and Vineyards").

The testing is summarized in this youtube video that's well worth watching, and the results have helped IBHS refine its guidance on wildfire-resistant homes (see the page of Wildfire at disastersafety.org)

Beyond the obvious material choices for siding, roofs and decking, there are a number of other key details to consider:
