Storm Damage Repair in Seattle, WA

Seattle's most destructive storm events are not rain events — they are the powerful windstorms generated by deep Aleutian Low pressure systems that track across the Pacific and funnel east winds through the Olympic Mountain rain shadow. The 2006 Hanukkah Eve Windstorm remains the benchmark event: gusts exceeding 69 mph knocked out power to over 1.5 million customers and toppled thousands of Douglas firs, western red cedars, and big-leaf maples onto homes, vehicles, and power lines across King and Snohomish counties. Seattle's unique tree canopy — the city is nearly 30% tree-covered — means that windstorm damage is dominated by tree falls rather than wind pressure on structures directly. Douglas fir root systems are particularly susceptible to toppling in saturated soils: after months of autumn rain, a single windstorm can tip trees that have stood for decades. Neighborhoods like Laurelhurst, Magnolia, and Seward Park, with mature old-growth canopy remnants, face disproportionate storm damage risk from both falling trees and large limbs that punch through rooflines and skylights.
