A gutter guard formed of a flexible strip of lattice-like plastic or expanded metal material has an upper edge insertable beneath the lower ends of the lowermost course of shingles overlying the gutter of a sloped roof, and has a lower edge which extends over and around the upper outer gutter edge. Tabs cut into material above the lower edge of the strip can be easily depressed downwardly by hand during installation to engage from below the underside of the inwardly facing lip at the outer gutter edge. Alternating flaps formed between the tabs, or a continuous outer edge extending along the tabs, project beyond the tabs and fold in line with the lower tab ends to hook over and around the gutter lip. The hooked outer edge is either flat initially and plastically deformable at installation over the gutter edge, or it is preformed into a hook extending below the tab ends. The material is sufficiently flexible so as to package in a roll.
