The ancient Romans understood the importance of directing waste water away from living areas. They even had a goddess of sewers, named Cloacina. While there is no concrete evidence that the Romans installed gutters on their homes, they did awaken the need for directing excess water away from living areas.
As roofs developed from grassy thatch to more solid materials such as wood, stone and earthen tiles, simple styles of a wooden gutter arose sometime in the 18th century. Wooden gutters, fastened by wrought-iron brackets, had to be replaced regularly. Less common gutter materials were lead, copper, tin and terneplate.
By the 20th century, most gutters systems comprised of galvanized iron or steel and aluminum. Today, vinyl is a very common gutter material. Elaborate gutter systems with mesh keep out roof debris and another accordion-shaped system splatters rainwater away from the building.
