Gutters are channels installed along the edges of roofs to collect and direct rainwater away from the building. They help prevent water damage to the roof, walls, and foundation by guiding runoff into downspouts, which then lead the water safely to the ground or drainage systems. Typically made from materials like aluminum, vinyl, or copper, gutters come in various shapes and sizes to fit different architectural styles. Regular maintenance, such as cleaning out debris, is essential to ensure they function properly and protect the structure from potential water-related issues.
