Roofing and Gutters
The most vulnerable part of a home is the roof since it is a surface on which flaming embers or other debris can land. Wood shingle roofs are extremely flammable. Gutters are another vulnerable area where improvements can be made. Installing gutters with screens will keep flammable debris from building up and becoming a nest for embers.
Attic and Crawlspace Vents
Vents on homes create openings for flying embers. Common 1/4” screens are ineffective and should be replaced or retrofitted with 1/16” wire mesh as fiberglass or plastic materials can melt and burn.
Creating Defensible Space
Defensible space is essential in slowing down or stopping the spread of wildfire to your home. It’s the buffer you create between a building on your property and the grass, trees, shrubs, or wildland around it. For detailed information visit
Effective windows are essential to protecting the interior of your home. Dual pane windows with Low-E coatings or tempered glass will increase the performance and may withstand higher temperatures before failing.
Combustible siding or other combustible, overlapping materials provide surfaces or crevices for embers to nestle and ignite. Stucco, brick, cement board and steel are better non-combustible choices. Maintain 6-inch ground-to-siding clearance.
Air Sealing and Insulation
Reducing the amount of air that leaks in and out of your home is a cost-effective way to protect your indoor air quality but also a cost-effective way to cut heating and cooling costs, improve durability, and increase comfort.
Powering Critical Loads with Clean Energy
Be prepared with back-up power during an extended electric outage. Understanding your critical load needs is necessary for determining the type and size of the system. Considering alternative energy sources to partner with a back-up system can help reduce the amount of greenhouse gas emissions we put into the air and provide the reassurance that power for the most important loads are available during an outage.
