Conditions That Cause Gutter Blockages
Blockages occur when organic matter and environmental grit settle inside gutter troughs. Common factors affecting drainage include:
- Fallen leaves, needles, and twigs shedding from nearby branches.
- Windblown dust, seed pods, and accumulated roof grit collecting in corners.
- Standing water caused by silt deposits restricting flow toward outlets.
- Nesting materials or small pests obstructing the upper reaches of downspouts.
