Gutters, downspouts, grading, and drainage are different parts of the same water-management picture. This page does not claim that a gutter guard prevents every water problem. It gathers public figures that explain why a working drainage path matters around a home.
For a homeowner, the practical takeaway is simple: notice how water leaves the roof after a storm, and deal with recurring overflow or drainage concerns before they become harder to understand.
