What is a drip edge?

A drip edge is a metal flashing that is installed at the edge of a roof to help direct water away from the fascia and prevent it from seeping into the underlying materials. Drip edges come in a variety of materials, including galvanized steel, aluminum, and PVC, and can be customized to fit the specific dimensions of a roof.

In addition to preventing water damage, drip edges also help to protect the underlying structure from pests, debris, and other potential hazards. They are typically installed underneath the shingles and over the underlayment, providing an extra layer of protection for the roof.

Proper installation of a drip edge is essential for maintaining the integrity of a roofing system. It should be installed with a slight outward cant to ensure that water is directed away from the fascia and into the gutters. Regular inspection and maintenance of the drip edge can help to prevent leaks and other issues that could compromise the roof's performance.

Overall, a drip edge is an important component of a roofing system that helps to protect the structure from water damage and other potential hazards.
