A rain gutter installed along the edge of a roof can help to prevent water damage to a house and its environs in several important ways.

Primary Function

1. The primary function of a rain gutter is to direct water from the roof of a home to the ground in such a way that it does not damage the building or lawn. This has several specific purposes.

   Protection From Runoff

2. Unchecked, rain washing off of a roof will run down the outer walls of a building, which may rot wooden houses. Rain gutters help to prevent rot.

   Preventing Flooding

3. By diverting water away from the foundations of homes, rain gutters can help to prevent basements from flooding.

   Preventing Erosion

4. Uncontrolled runoff from roofs can contribute to unsightly soil erosion on lawns and around the home. Gutters help homeowners to control the flow of water from the roof of their home.

   Saving Money

5. Rain gutters help homeowners save money by preventing flooding, soil erosion and rot and by protecting the paint or stain on their homes.
