Debris and Drainage Conditions Affecting Runoff
Clogs typically develop when falling organic matter settles directly into the open channels or collects around downspout openings. Several factors influence how quickly material accumulates along your roof edges:
- Deciduous leaves, twigs, and seasonal blossoms settling into flat runs.
- Needles, seed pods, and fine organic grit shedding from nearby trees or roof surfaces.
- Standing water that remains trapped behind localized obstructions.
- Wind-driven debris settling unevenly across multi-tiered roof valleys.
