The answer to 'why is my asphalt shingles clogged gutters' is that clogged gutters are a common issue caused by debris, leaves, and granules from worn-down asphalt shingles accumulating in the gutters. This can lead to water backup, roof damage, and even foundation problems if left unaddressed.
Clogged gutters prevent proper drainage and can cause water to overflow, leading to issues like rotting fascia boards, leaks, and even basement flooding. The shingle granules that end up in the gutters are a sign that your roof is nearing the end of its lifespan and may need replacement soon.
