When Toronto gutters fill up
Trees common in the region, including sugar maple, red maple, bur oak, hickory, American elm, white pine, and spruce, drop heavy materials throughout the year. Spring drops seed wings and small twigs, while leaf drop usually peaks in mid October. Fall leaves and pine needles quickly fill roof troughs. In Toronto, freezing nights bring snow and ice, turning trapped water into ice dams during winter. Ice dams push heavy weight against the roof edge, loosening structural fasteners. We recommend cleaning at least twice a year, spring and fall, to keep channels empty before winter freezes start and after fall leaves finish dropping.
