When Washington gutters fill up
Trees common in the region, including bur oak, silver maple, green ash, hackberry, and cottonwood, drop heavy seasonal debris. Cottonwood fluff coats roof channels during spring, ash seeds drop early, and leaf drop usually peaks in mid October. Windstorms also blow grit and dust onto the roofline, filling channels with heavy silt. In Washington, winter brings freezing nights and snow, making ice dams in gutters a serious concern when trapped water freezes solid. We recommend cleaning at least twice a year, spring and fall, to keep every channel and downspout clear before freezing temperatures arrive or major heavy rains begin.
