Property Conditions That Lead to Clogs
Gutter troughs collect whatever wash enters from the roofline during storms and dry spells alike. While wind and surrounding vegetation deposit twigs, fallen foliage, and organic matter into the channels, roof runoff can also wash fine asphalt shingle granules into the system. Over time, standing organic material forms dense blockages at downspout outlets, preventing water from escaping and forcing runoff to back up behind the debris.
