Install a rain chain on the roof overhang of your house to add a functional and decorative element to your home's exterior. As rainwater flows down the chain, it prevents water from splashing onto the ground, protecting your landscaping and preventing soil erosion. The rain chain can be attached to the gutter system or hung from a bracket, and it can be made from materials such as aluminum, iron, or ceramic. Choose a rain chain design that matches the architectural style of your home and enhances its curb appeal.
