Factors That Lead to Gutter Blockages
Blockages occur when organic matter and fine grit settle into the channels and obstruct normal water movement. If trees overhang the roof, fallen leaves, twigs, and seed pods can quickly fill the troughs. Even without heavy tree canopy nearby, wind-blown grit from roofing shingles and nesting material from birds or pests can collect over time and restrict water flow toward the outlets.
