A debris guard is described for retro-fitting to an existing rain gutter or integral with a newly-fabricated gutter which allows ingress of rain water to the gutter but significantly restricts the accumulation of leaves, twigs and otherwindblown debris within the gutter. The guard comprises an open channel portion (21) formed from a front face (23), an opposing rear face (24) and a lower face (25). A panel (26) covers the required length of the gutter (20). A front panel (27) depends from the leading edge of the cover panel (26) to overlap with the front face (23) of the gutter (20). The front panel (27) includes two linear rows (32,33) of evenly-spaced openings (34). Each opening (34) includes a tab (35) extending downwards and inwardly towards the rear face (24) of the gutter (20). In use, rain water runs off the roofing material onto the cover panel (26), down the front panel (27) and onto the front face of the tab (35) and then into the channel portion (21). Each opening (34) allows rain water to pass through but substantially prevents the passage of any leaves or other debris from the roof. |
