A gutter is a channel or trough designed to collect and direct rainwater away from a building's roof. It is typically installed along the edges of roofs and helps prevent water damage to walls and foundations. Gutters are usually made of materials like metal, plastic, or wood and can vary in size and shape. In addition to protecting buildings, gutters are also important for managing stormwater runoff. They can be connected to downspouts, which carry the water down to the ground or into a drainage system. Proper maintenance of gutters is essential to ensure they function effectively and prevent clogs.
