What is drip edge on a roof?

A drip edge is a metal flashing installed along the edges of a roof to help direct water away from the roof decking, fascia, and soffit. It provides a clean, finished look to the roof edge and helps prevent water damage by directing rainwater into the gutters or off the roof entirely. Drip edges also protect against wind-driven rain and prevent water from seeping under the roofing materials.

Drip edges are typically made of aluminum, galvanized steel, or PVC and come in a variety of colors to match the roof. They are installed under the first row of shingles or roofing material along the eaves and rakes of the roof. Proper installation of drip edges is important to ensure they function effectively and provide proper water drainage.

In addition to protecting the roof and preventing water damage, drip edges also help to prevent pest infiltration and make roof maintenance easier by reducing the risk of rot and decay. Overall, installing a drip edge is a simple and cost-effective way to improve the longevity and performance of a roofing system.
