What is Drip Edge?

Drip edge is a small, L-shaped piece of metal that is installed along the edges of a roof. It is also sometimes called a roof drip cap or a drip flashing.

The primary purpose of drip edge is to prevent water from seeping under the shingles and causing damage to the roof and the underlying structure. When it rains, water flows down the roof and off the edges. If there is no drip edge, the water can run under the shingles and cause leaks and water damage.

Drip edge is installed along the eaves (the lower edge of the roof that extends beyond the side of the house) and the rakes (the edge of the roof along the gable ends). It is usually made of aluminum or galvanized steel and is bent at a 90-degree angle, with the shorter leg pointing up towards the roof and the longer leg pointing down towards the ground.

There are several benefits to using drip edge. In addition to preventing water damage, it helps to protect the roof from wind and ice damage. It also helps to keep debris, such as leaves and branches, from getting caught under the shingles and causing damage. Drip edge also adds a finished look to the roof, as it covers the rough edges of the roof deck and helps to define the lines of the roof.

In general, drip edge is an important component of a roofing system and is essential for protecting the roof and the underlying structure from water damage. It is a simple and effective way to extend the life of a roof and keep it in good condition.
