Debris and Drainage Conditions Affecting Gutters
Accumulation inside gutters varies depending on nearby overhead tree cover, roof pitch, and prevailing winds. Roof run-off can carry loose matter that settles into troughs and creates blockages, particularly when:
- Overhanging branches drop leaves, seed pods, or small twigs directly onto roof valleys.
- Organic silt and roofing grit settle along the bottom of channels during light rain.
- Downspout strainers become capped by compacted foliage, preventing proper drainage.
