Common Causes of Blocked Gutters and Downspouts
Water flow issues typically arise when organic material and outdoor debris settle inside the gutter channels. Recognizing the primary sources of blockage helps determine the level of clearance needed:
- Decaying leaf litter, twigs, and broken organic matter shedding from adjacent overhead branches.
- Settled roof grit, moss, and airborne dirt accumulating along the channel bottom and choking outlet collars.
- Nesting activity, plant growth, or trapped items creating barriers near the upper elbows of downspouts.
