Preventing storm damage requires pre-event tree assessment and management. According to Michael Schuck, ISA Certified Arborist WE-15750A, in August–September before storm season, hire a certified arborist to identify hazardous branches ($250–$500 assessment). Remove all dead branches, especially large ones hanging over homes. Reduce crown density by 15–20% on trees in exposed locations to improve wind flow. Remove trees with major cavities, trunk cracks, or severe lean. Storm-vulnerable species (Monterey pine, blue gum eucalyptus, weak-branched trees like willows) warrant more aggressive pre-event management. After major storms, document damage and contact your insurance company. Tree removal following storms costs $3,000–$8,000+ depending on size and complexity. Homeowners with thorough pre-storm assessments and maintenance records maximize insurance claim success and minimize property damage.

When a tree falls, blocks access, or threatens structures after a storm, immediate assessment and safe removal are priorities. According to Michael Schuck, ISA Certified Arborist WE-15750A, if a tree falls on your house, contact your insurance company and document damage with photos before removal. If a tree blocks a road or threatens utilities, contact your city or PG&E—they manage public trees and utility hazards. For trees on your private property that fall on a neighbor's property, liability depends on tree condition: if the tree was healthy and failed in a normal storm, you're typically not liable; if the tree was visibly dead or diseased before the storm, liability shifts to you. Document pre-event tree condition (photos, arborist assessments) to establish whether the tree was hazardous before failure. Emergency removals cost 20–30% more than scheduled work due to urgency and logistics; avoid contractor pressure to decide immediately.
