Factors That Influence Gutter Blockages
Blockages form differently based on the surroundings of each residential parcel. Accumulations can build up gradually or spike after periods of heavy wind and rain. Common contributing elements include:
- Foliage, pine needles, twigs, and seed pods dropping directly onto roof planes.
- Settled roof grit and decaying organic silt collecting inside channel corners.
- Nesting material or pest debris accumulating near downspout openings.
- Shallow channel slopes that allow standing water to hold fine debris in place.
