Drip edge routes water down and away from the vulnerable joint where the roof underlay and the rake or facia boards meet. Keeps water from wicking back into this area and into the edge of the plywood underlayment.

Water and ice shield does the same thing for the lower portion of the roof and in valleys where snow can collect, melt, re-freeze, melt and wick back under the shingles.

IIRC the shield should extend 2-3 ft up the roof past the point where the verticle exterior walls meet the rafters/trusses, and 3 ft up each side of a valley. So depending on your overhang, could be a total of 4-5 ft. Don't hold me to that, just what I remember, may not be fact.
