A leaf excluder for a rain water guttering of channel form having one outer upper free edge terminating in a curled bead. The leaf excluder comprises a strip of flexible resilient sheet-like material with a plurality of bead engaging fingers along and projecting from one edge and a plurality of water passing slots in the strip at an angle to the length dimension of the strip. The width of the strip between opposite edges is such that with the fingers engaged with a guttering bead and the opposite edge of the excluder engaged in the diagonally opposite corner of the guttering the body of the excluder will be upwardly arched to cause the slotted part of the excluder to bear against the terminal end of roof cladding which overlaps the inner upper free edge of the guttering.
