For the most part, water is kept from penetrating a roof thanks to the overlapping nature of roofing shingles. So long as all of the shingles remain in place, all parts of the roof remain protected–all parts, that is, except for the terminal edge. The problem here is that, during heavy rain storms, wind can easily push water back up beneath the last row of shingles. Once it has penetrated in this way, that water will cause no end of trouble, leading to leaks, rot, and other problems.
The Roof Drip Edge
The roof drip edge performs a fairly simple task: it acts as a physical barrier, preventing water from creeping back up the roof below the edge of the bottom row of shingles. Like flashing, drip edges consists of a piece of molded metal–usually aluminum. This aluminum comes in the shape of the letter T. One of its top edges is affixed with roofing nails beneath the last row of shingles. The long stem then hangs downward, acting to block water from moving under the shingles.
