Why gutter cleaning matters

A clogged gutter causes damage in several places at once:
- Foundation and basement. Overflow soaks the soil against the wall, which can lead to cracks and a wet basement.
- Fascia and roof edge. Water that backs up behind the gutter rots the fascia board and can reach the roof deck.
- Siding and paint. Overflow leaves stains, peels paint and can get behind siding panels.
- The gutters themselves. Wet debris is heavy. It pulls on the hangers until the gutter sags, and it holds moisture against the metal.
- Ice and pests. In winter a clogged gutter fills with ice. In summer, standing water draws mosquitoes, and wet debris draws nesting birds and insects.
