Gutter accessories are an important part of any gutter system. The accessories are what help your gutters stay free from debris and rain overflow. A few of the most common accessories installed include downspouts, elbows, offsets, miters and end caps. These various components work to move the water down the gutter and funnel it away from your home to protect the exterior of your home from water damage. Each component works to funnel the water away in various ways, for example offsets are used to get over a brick or porch ledge and miters are used to turn corners.
