Gutters are a component of a building’s roofing system that collects and channels rainwater away from the foundation of the building. Gutters are typically made of metal, plastic, or wood, and are installed along the edges of the roof. The water is directed through downspouts, which then channel the water away from the building into drainage systems. The main function of gutters is to protect buildings from water damage caused by rainwater by directing it away from walls and foundations.
