A rainwater gutter is a channel or trough that runs along the edge of a roof or building to collect and divert rainwater away from the structure. Rainwater gutters help prevent water damage to the building's foundation and walls.
Rainwater gutters are typically made of materials like aluminum, vinyl, or galvanized steel. They are installed to slope slightly downward so the water can flow to a downspout or drain. Proper maintenance of gutters, such as regularly cleaning out debris, is important to ensure they function effectively.
