What is Drip Edge?
Roofing Glossary · Roof Anatomy
Definition
A metal strip installed along the eaves and rakes at the edges of the roof to direct water away from the fascia and underlying construction. Drip edge prevents moisture from wicking back under the shingles through capillary action. Most building codes require drip edge installation, and it is typically installed before underlayment at the eaves and over underlayment at the rakes.
