To fix an overhang that’s too short, buy some aluminum drip edge (aka drip-cap flashing). It’s typically sold in 8-ft. lengths, and can be cut with tin snips or even poultry shears. Slide the wide, flat flange of the flashing under the first course of shingles and adjust it to extend over the gutter.
How far should shingles overhang drip edge?

How far should shingles overhang the rake?
The edge of the shingles should hang over a roof between an inch and an inch and a half — or between a half inch and three-quarters of an inch if drip edge flashing is installed. Too much overhang and the shingles could blow off in high winds; too little can allow water to seep into rake or fascia boards.
Does drip edge go on before fascia?
The correct placement of a roof drip edge is on top of the roof’s exterior cover directly between the sheathing and the fascia board, which forms a drainage gap between the drip edge and the fascia board.

How far down should gutters be from shingles?
If a drip edge isn’t there, the edge of the shingles should extend over the backside of the gutter—with about 3 inches to 4 inches of the gutter width—so the water won’t drip behind it and rot the fascia board. U-type brackets usually hold the gutter about a half-inch to 1 inch away from the fascia board.
