Your roof is designed so that rain, as well as melted snow and ice, runs down and collects into the gutters. The water then runs into the downspouts and down and away from the foundation of your house. Because of this, it's important to keep your gutters and downspouts in good repair. If they are blocked or they leak, for example, the water will end up right down next your house. Not only can this cause flooding in your basement, but the excess water can also cause damage to the foundation of your home.

Unless you have installed gutter guards, the most common problem associated with this water collection system is leaves, tree branches, nuts, and gunk clogging up your gutters. Clogs occur most often where the downspout connects into the gutter. However, they can happen anywhere in a gutter. Once your gutter is clogged, the water runs over its sides instead of being channeled into the downspouts.
