What Is Drip Edge? Why Do I Need It?

When it comes to roofing, one of the most important components is the drip edge metal. Drip edge metal is a type of flashing that is installed at the edges of a roof to protect it from water damage. In this blog, we will take a closer look at what drip edge metal is, why it is important, and how it is installed.

What is Drip Edge Metal?

Drip edge metal, also known as edge metal, is a piece of metal that is installed along the edges of a roof. It is typically made from galvanized steel or aluminum, and it is available in a variety of sizes and shapes. The most common shapes are L-shaped and T-shaped.

Why is Drip Edge Metal Important?

Drip edge metal serves several important functions for a roof. First and foremost, it helps to protect the roof from water damage. When rainwater flows down the roof, it can seep under the shingles and damage the underlying structure of the roof. Drip edge metal prevents this from happening by directing the water away from the edges of the roof and into the gutters.

Drip edge metal also helps to prevent insects and rodents from getting into the roof. By creating a barrier at the edge of the roof, it makes it much more difficult for pests to find their way into the attic.

Finally, drip edge metal can improve the appearance of a roof. It gives the roof a finished look and can add to the overall curb appeal of the home.

How is Drip Edge Metal Installed?

Installing drip edge metal is a relatively simple process. Here are the basic steps:

  1. Measure the roof: Before installing drip edge metal, you will need to measure the length of each edge of the roof to determine how much material you will need.
  2. Cut the drip edge metal: Once you have the measurements, you can cut the drip edge metal to the appropriate lengths. You will need to use tin snips or a saw to cut the metal.
  3. Install the underlayment: Before installing the drip edge metal, you will need to install a layer of underlayment along the edges of the roof.
  4. Install the drip edge metal: Starting at one end of the roof, position the drip edge metal so that it extends about an inch over the edge of the roof. Nail it in place using roofing nails. Repeat this process for the rest of the roof.
  5. Install the shingles: Once the drip edge metal is in place, you can install the shingles over it. Be sure to position the shingles so that they overlap the drip edge metal.

In conclusion, drip edge metal is a crucial component of any roof. It protects the roof from water damage, pests, and adds to the overall appearance of the home. If you are installing a new roof or repairing an existing one, be sure to include drip edge metal in your plans.
