Factors That Create Debris and Drainage Blockages
Blockages occur when organic matter and windblown material collect in the channels over time. Understanding what gathers along your roofline helps you evaluate when clearing is necessary.
- Fallen leaves, small twigs, and seed pods that settle into open channels.
- Wind-blown organic silt and roof grit that accumulate along low-pitch runs.
- Nesting materials or pests resting in quiet, unmaintained corners.
- Downspout strainers or elbows choked by compressed organic debris.
