The answer to 'why is my gutter dirty' is that gutters can become clogged with leaves, twigs, dirt, and other debris over time. This buildup of debris prevents proper drainage and can lead to a variety of issues, including water damage, pest infestations, and even foundation problems.
Some common causes of dirty gutters include overhanging trees, high winds, and heavy rainfall. Symptoms of a dirty gutter include water spilling over the sides, sagging or pulling away from the roof, and the presence of pests like birds or rodents. To solve the problem, you'll need to regularly clean out your gutters to remove any accumulated debris.
