The answer to 'what causes gutters' is that gutters are designed to collect and channel rainwater away from the home's foundation. Gutters are essential for protecting the home from water damage, as they prevent water from pooling around the foundation, which can lead to cracks, leaks, and other structural issues.
Gutters can become clogged with leaves, twigs, and other debris, which can prevent them from functioning properly. This can cause water to overflow and spill onto the ground around the home, potentially leading to erosion, basement flooding, and other problems. Regular gutter cleaning and maintenance is important to ensure that they continue to work effectively.
