Common Clog Conditions and Drainage Factors
Blockages occur when organic matter and settled sediment accumulate along horizontal channels or inside vertical outlets. Specific conditions that often affect drainage include:
- Fallen leaves, needles, and twigs collecting along gutter channels.
- Settled grit washed down from aging roof materials.
- Wind-blown dirt and organic silt that restrict water movement.
- Debris lodging at the upper mouth of downspouts.
