Debris and Drainage Conditions That Affect Runoff
Gutter channels and downspouts collect different types of organic matter and roof grit depending on the nearby surroundings. Understanding what reaches your roofline helps determine the appropriate cleaning approach:
- Leaves, twigs, and seed pods that settle in open channels and restrict water flow
- Granules from aging shingles that accumulate in low spots and create dense silt
- Compacted debris that blocks the upper openings of downspout assemblies
