Drainage and Debris Factors for Local Homes
Accumulation varies widely from one property to another based on surrounding foliage and roof design. When pine needles, broad leaves, twigs, or roof grit settle in channels, water flow slows down and debris can form dense dams along the eaves.
- Overhanging branches dropping seasonal foliage directly onto roof planes.
- Windblown grit and organic matter settling in low-slope valleys.
- Trapped twigs obstructing the outlets where gutters feed into downspout openings.
