Common Debris and Drainage Conditions
Drainage issues typically develop when seasonal materials accumulate across roof valleys and along horizontal gutters. Several property conditions commonly influence how debris collects:
- Overhanging tree branches shedding needles, leaves, or seed pods directly onto roof surfaces.
- Accumulated grit and granules washing down from aging roof shingles.
- Trapped organic matter decaying into thick sediment along low-slope sections.
- Windblown twigs and plant matter catching at downspout openings.
