Conditions That Cause Trough and Downspout Clogs
Troughs and downspouts restrict flow when natural debris accumulates or drainage paths become obstructed. Several conditional factors can lead to blockages on any given property:
- Fallen leaves, needles, twigs, and organic matter collecting in troughs
- Roof grit washing down from shingles and settling at low points
- Nests, pests, or animal droppings resting near downspout openings
- Standing water caused by inadequate slope rather than simple debris
