What is a wildfire home retrofit?
A wildfire home retrofit improves an existing structure so vulnerable exterior details are better prepared for wildfire exposure. The work may be as focused as replacing exterior vents or as broad as coordinating several upgrades around the roofline, eaves, siding, attachments and the area immediately next to the home.
A retrofit is different from assuming the entire home must be rebuilt. The useful starting point is the condition of the actual property, followed by a scope that distinguishes maintenance, repair and replacement.
Common retrofit categories
- Ember-resistant vent replacement or screening
- Eave and soffit improvements
- Roof-edge, flashing and gutter work
- Exterior gaps, siding and attachment review
- Deck, fence and combustible-material interfaces
- Defensible-space and near-home combustible reduction
Existing homes do not all have the same scope
Construction era, remodel history, vent layout, roof condition and surrounding site conditions can change the project. A home-hardening assessment can help define the work before you ask several providers to price it.
Ventilation and code still matter
California wildfire guidance recommends reducing ember entry through vents, but vent modifications also need to preserve required airflow. Ready for Wildfire advises homeowners to check local ventilation requirements and use appropriate professional help when modifying vents.
Planning the estimate
Ask for a written scope that identifies openings or components included, proposed products or materials, repair assumptions, permit assumptions and cleanup. A comparable scope makes contractor or provider estimates easier to evaluate.
