Gutter guards prevent clogs by blocking leaves, twigs, and other debris from entering the gutter while allowing water to flow freely. Depending on the type of guard, they can filter out both large and small debris, reducing the frequency of gutter cleaning and preventing water damage.

Gutter guards, especially micromesh and metal varieties, are highly effective at keeping debris out of gutters. By preventing clogs, they reduce the need for frequent maintenance and protect the home from potential water damage caused by overflowing gutters.
