The answer to 'why is my architectural shingles clogged gutters' is that architectural shingles can sometimes contribute to clogged gutters. These thicker, textured shingles can shed more granules over time, which can then accumulate in the gutters and downspouts. This can restrict water flow and lead to overflowing gutters.
Other common causes of clogged gutters include leaves, twigs, and other debris that gets blown into the gutters. Over time, this buildup can prevent proper drainage and cause water to back up, potentially leading to roof leaks, foundation damage, and other issues.
