Factors That Influence Clogs and Drainage Problems
Accumulations in gutters are rarely identical from one home to the next. The need for clearing typically depends on practical conditions around the immediate structure:
- Overhanging branches dropping leaves, twigs, seeds, or needles directly onto roof valleys.
- Windblown grit and organic matter settling inside channels over extended dry or wet spells.
- Shallow gutter pitch that prevents standing water from carrying fine residue to the outlets.
- Nesting birds, rodents, or pests depositing materials in corners and downspout openings.
