Debris and Drainage Conditions That Affect Flow
Runoff issues typically develop when organic material settles inside the gutter troughs and restricts movement toward outlets. Common obstructions include:
- Fallen leaves and needles that form dense mats along low-slope runs.
- Small twigs and airborne organic matter settling near downspout openings.
- Granules washed from roof surfaces collecting in standing water.
- Windblown dust mixing with organic material to create heavy, slow-draining sludge.
