Conditions That Cause Clogged Gutters
Drainage blockages typically develop when outdoor debris collects inside horizontal gutter troughs and washes toward downspout openings. Several factors influence how quickly material accumulates on a roofline:
- Deciduous leaves, twigs, and plant matter dropped directly onto the roof deck.
- Pine needles, seeds, and airborne organic material that settle in quiet water pockets.
- Granule loss from aging shingles that settles along the bottom of the channel.
- Nesting activity, bird droppings, or standing water that accelerates muck buildup.
