Eavestroughs, also known as gutters, are channels installed along the edges of roofs to collect and direct rainwater away from a building. They help prevent water damage to the foundation, walls, and landscaping by guiding runoff to downspouts, which then carry the water safely to the ground or drainage systems. Typically made from materials like aluminum, vinyl, or copper, eavestroughs 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 avoid blockages that can lead to overflow and potential damage to the structure of the building.
