Clogged gutters negate their benefits. Depending on the geographic region, they can fill with leaves, pine needles, oak tassels, asphalt and other shingle debris, and nests that harbor infestation. They can trap stagnant water in the debris and become a breeding area for mosquitoes. Dried debris, particularly pine needles, create a potential fire hazard during drought conditions in areas prone to forest fires.
In areas subject to winter conditions, clogged gutters cause dangerous icicles and water damming, forcing melting water to back under shingles and leak into the interior. Water in foundations can freeze, crack and buckle.
