As a construction expert with years of experience in the field, I am well-versed in a variety of tasks, including the installation of roof drip edges. Drip edges are a crucial component of roofing systems, designed to prevent water from seeping under the shingles and causing damage to the roof deck and interior of the building. Here's a step-by-step guide on how to properly install a drip edge.

Step 1: Preparation

Before you begin the installation process, ensure that you have all the necessary tools and materials. You will need a drip edge, underlayment (or ice-and-water shield if you live in an area with heavy snowfall), a utility knife, a hammer, roofing nails, a pry bar, and a ladder. It's also a good idea to have a friend to help with the installation.

Step 2: Measure and Cut the Drip Edge

Start by measuring the length of the eaves. Cut the drip edge to fit the length of the eaves using a utility knife. Make sure to cut straight and clean edges to ensure a proper fit.

Step 3: Position the Drip Edge

Lay the drip edge along the eaves, with the flange facing down and the drip edge lip hanging over the edge of the roof. The flange should sit on the roof sheathing.

Step 4: Secure the Drip Edge

Use roofing nails to secure the drip edge to the roof. Space the nails approximately 12 inches apart along the flange. Make sure the nails are long enough to penetrate through the drip edge and into the roof sheathing.

Step 5: Install the Underlayment

Once the drip edge is secured, it's time to install the underlayment. Start at the bottom and work your way up, overlapping each course by at least 2 inches. Secure the underlayment with roofing nails, ensuring it is tightly fitted against the drip edge.

Step 6: Install at the Gable End

At the gable end, cut the drip edge to fit the corner. Install the drip edge in the same manner as along the eaves, making sure it is properly secured and the underlayment is installed correctly.

Step 7: Inspect and Adjust

After the installation is complete, inspect the drip edge and underlayment to ensure they are properly aligned and secured. Make any necessary adjustments to ensure a watertight seal.

Installing a drip edge is a critical step in protecting your roof from water damage. By following these steps, you can ensure a professional and long-lasting installation.

The best way is to install the roof drip edge only along the eaves first, then place ice-and-water barrier (in the snowbelt) or felt paper (underlayment) over the drip edge.read more >>
