Abstract: A rotatable gutter system that includes a gutter and a pair of support members each located at an opposite end of the gutter to mount it onto a building. The gutter is rotatable relative to the support members about an axis that extends between them. The gutter includes a drive member accessible through an opening in one of the support members. Rotation of the drive member causes concomitant rotation of the gutter. In this way, the gutter can be inverted for easy cleaning and for storage during winter months to prevent ice buildup in the gutter. An elongated drip edge can be provided above the gutter such that it contacts an outer surface of the gutter when it is rotated to a closed (inverted) position. The gutter can have an end piece at each end with the drive post being a unitary extension of that end piece.
