an elongate gutter cover adapted to be positioned over the open trough of a conventional rain gutter . the gutter cover is configured to deflect leaves and other debris away from the gutter . the rain water , however , follows the contour of the gutter cover into the gutter itself . the gutter cover is made from materials that are substantially entirely deformation reversible between two extreme configurations . starting with the configuration desired in service , the gutter cover is flattened to permit coiling in a longitudinal dimension . upon being uncoiled , the gutter cover resumes the operative configuration in which it is used . in some embodiments , the gutter cover may comprise several plastic materials that have been coformed to provide the desired characteristics . the invention provides a novel method of installing a gutter cover system with less labor and skill than has typically been required in the prior art .
