Storm Damage Repair in Sacramento, CA

Sacramento's storm damage profile is dominated by the atmospheric river events of the wet season and the Valley's periodic windstorm events, with a hail season that is less frequent than Great Plains cities but more severe when it occurs due to the altitude and instability of storms that develop along the Sierra Nevada foothills. Atmospheric river events — classified as Category 3 through 5 on the Ralph scale — bring sustained winds of 35 to 55 mph to the Sacramento Valley for 24 to 48 hours, generating widespread roof damage to the city's stock of aging composition shingle homes from the 1950s through 1990s. The January 2023 atmospheric river series brought multiple rounds of 50 mph wind gusts to Sacramento, toppling trees throughout the older neighborhoods of Land Park, East Sacramento, and the Fab 40s district and causing an estimated $50 million in tree-related property damage across the metro. Sacramento Valley north wind events — called Diablo winds locally — can deliver 60 to 80 mph gusts from the north on rare occasions, reversing the usual Delta Breeze airflow pattern and generating fire and structural damage risk for the northern portion of the metro. Hail events occur 3 to 6 times per year in Sacramento, with the most damaging events associated with cold-season convective systems in November through March when Sierra Nevada instability is highest.
