Debris and Drainage Conditions
Outdoor debris gradually accumulates in open channels and creates obstructions throughout the system. Typical property factors that influence accumulation include:
- Fallen leaves, small twigs, and airborne organic matter collecting along roof valleys.
- Windblown dust, seed pods, and degraded roofing granules that form heavy sediment in channel corners.
- Standing water that remains trapped behind localized buildup instead of moving toward outlets.
