Debris and Drainage Conditions That Affect Flow
Blockages typically develop when outdoor debris accumulates along troughs or gathers near outlets. Factors that can influence drainage include:
- Fallen leaves, needles, seed pods, or small twigs settling into the channels.
- Organic silt accumulation that prevents water from flowing smoothly toward downspouts.
- Debris trapping standing water, which increases weight along the roofline.
- Windblown matter settling behind brackets and structural corners.
