Conditions That Cause Gutter Blockages
Drainage paths typically back up when foreign material collects along the trough or settles into downspout outlets. Conditions that regularly contribute to gutter clogs include:
- Fallen leaves, small twigs, and airborne organic debris settling into open channels.
- Windblown seeds, seed pods, and pine needles lodging tightly in downspout elbows.
- Granules shed from asphalt shingles gathering in low spots and slowing water flow.
- Nesting material or pest activity obstructing bends where gutters meet vertical leaders.
