Factors Contributing to Clogs and Water Accumulation
Overhead vegetation, windblown materials, and accumulated rooftop sediment frequently restrict the path of rainwater through exterior drainage systems. When dead foliage, twigs, and granules settle along the trough, water movement slows and debris forms dense mats. During steady or heavy rain, these blockages impede flow toward the outlets, resulting in standing water that places unnecessary weight on gutter hangers and fascia boards.
