    Abstract: Gutter protector (10) comprises a profiled sheet (28) that extends over a gutter invert (24A) above a gutter floor (24) for collecting water and debris that would otherwise directly collect in the gutter invert (24A). The gutter protector (10) includes a spacer (30) for spacing adjacent profiled sheets (28) by a first gap (32) that allows water to the substantial exclusion of leaves and debris to fall through the gap (32) into the underlying gutter invert (24A).
