Debris and Drainage Conditions That Affect Runoff
Gutters and downspouts become restricted when organic matter and fine grit collect along the channel beds. Conditions that frequently impede smooth water runoff include:
- Decaying leaves, twigs, and seed pods settling along the bottom of the gutter troughs.
- Accumulated roof shingle granules creating dense, heavy dams near drainage openings.
- Debris catching on internal hanger brackets and causing gradual blockages across straight runs.
- Matted organic buildup wedging tightly inside downspout drop outlets.
