How to Install Roof Drip Edge

Eaves, Rakes, Overlap & Nailing Sequence

This guide explains the correct way to install roof drip edge metal along every eave and rake. The critical sequence: drip edge goes UNDER the underlayment at eaves (so water hits the metal and runs off), and OVER the underlayment at rakes (so wind-driven rain cannot blow under the felt). Pieces should overlap 2-3 inches with nails every 8-12 inches. The guide includes diagrams for hip roofs, valleys, and gable end transitions. Pair with our Drip Edge Calculator.
