Conditions That Cause Blocked Gutters
Blockages occur when outdoor matter settles in the troughs and prevents water from moving freely toward the downspouts. Common factors that lead to clogs include:
- Fallen leaves, needles, twigs, and seed pods accumulating along long gutter runs.
- Granules shed from aging roof shingles gathering in low spots and corners.
- Windblown dust and organic matter decaying into heavy, water-retaining sludge.
- Nests, pests, or small animals creating localized barriers near outlets.
