When University of California-Davis gutters fill up
Trees around University of California-Davis drop heavy amounts of leaves, needles and seeds directly onto roof surfaces. These debris items wash into drainage channels during light rain, creating dense clogs inside every downspout. Freezing nights are rare here, ice dams in gutters are not an issue, and snow is rare in California. However, fall storms quickly push dry clutter straight into trapped drainage runs. We recommend cleaning at least twice a year, spring and fall, to keep drainage clear before winter rains arrive. Scheduled spring work clears winter accumulation, while fall visits prepare roofs for heavy rain so water never pools around upper building walls.
