Leaves and needles that clog local gutters
Trees common across this region drop heavy debris into drainage systems throughout the year, though the specific species mix differs across Michigan. Broadleaf trees like sugar maple, red maple, bur oak, hickory, and American elm drop large leaves during fall. Sugar maples also shed winged seed pods in late spring. Conifers such as white pine and spruce drop slender needles that pass through standard gutter guards and settle into thick, dense mats at the bottom of the gutter system. Pine needles combine with wet soil and fallen leaves, clogging downspout openings. Without routine cleanings, these mixed tree drops prevent melting snow and spring rains from draining properly.
