What is a drip edge on a roof?

A drip edge is a thin strip of metal that is installed along the edges of a roof to help direct water away from the fascia and into the gutters. It serves as a barrier that prevents water from seeping under the roofing material and causing damage to the underlying structure.

Drip edges are typically made of aluminum, galvanized steel, or PVC, and come in a variety of shapes and sizes to accommodate different roof designs. They are usually installed under the roofing material and over the top of the fascia board, providing a clean, finished look to the roof.

In addition to directing water away from the fascia, a drip edge also helps prevent wind-blown debris from getting under the roofing material and causing damage. It can also help prevent insects, rodents, and other pests from entering the roof structure.

Overall, a drip edge is an essential component of a well-constructed roof system, helping to protect the home from water damage and other potential issues.
