The bent aluminum or galvanized metal strip that fits the edges of the entire roof to divert water runoff is called a drip edge.

It's not to be confused with eave strips, which are generally a type of felt material designed to prevent wind-driven rain from getting under the roofing material at the edge of the roof.
A bent aluminum or galvanized metal strip that fits the edges of the entire roof to divert water runoff is called a drip edge.
