Dirty gutters can be a headache. For various reasons, gutters get dirty. Leaves, twigs, and rubbish from nearby trees might get into gutters, blocking drainage. Plus, a variety of elements, including trash, dust, and other particles, build up and create blockage by being carried into the gutters during rains. The lack of maintenance cannot be ruled out either. Irregular cleaning causes grime and dirt to build up in the gutters.
