How to Install Ice and Water Barrier on Your Roof 1

What is Ice and Water Barrier?

Before we dive into the process of installing ice and water barrier on your roof, it is important to understand what it is. Ice and water barrier is a type of underlayment that is designed to protect your roof from water intrusion. It is typically made of a rubberized asphalt material, which allows it to adhere to the surface of your roof. This barrier should be installed over the top of your existing roof deck and will provide an added layer of protection against water damage.

Materials Needed

Now that you understand what ice and water barrier is, here is a list of materials that you will need for the installation process:

  • Ice and water barrier
  • Roofing nails
  • Hammer or roofing nail gun
  • Utility knife or roofing snips
  • Roofing cement
  • Roofing tape
  • Roofer’s safety harness
  • Step-by-Step Installation Process

    Now that you have all of your materials ready, let’s walk through the installation process step-by-step:

    Step 1: Prep Your Roof

    The first step in installing ice and water barrier is to prep your roof. This means removing any debris or loose materials from the surface of your roof. You will also need to check your roof for any damage or leaks.

    Step 2: Measure and Cut the Barrier

    Next, you will need to measure and cut the ice and water barrier to fit your roof. Always cut the barrier in small sections to prevent it from sticking to itself. Be sure to overlap the sections by at least 3 inches to create a watertight seal.

    Step 3: Apply the Barrier

    Once your ice and water barrier is cut to size, it’s time to apply it to your roof. Starting at the bottom of your roof, peel back the backing of the barrier and carefully place it onto the roof deck. As you work your way up the roof, be sure to smooth out any wrinkles or air pockets. Use roofing nails to secure the barrier to the roof.

    Step 4: Seal the Edges

    After the barrier is in place, it’s important to seal the edges with roofing cement. Apply cement to all edges and use roofing tape to reinforce the seal.

    Step 5: Repeat the Process

    Continue this process until your entire roof is covered with the ice and water barrier. Be sure to overlap each section by at least 3 inches for a watertight seal.

    Step 6: Clean Up

    Once the barrier is in place, you’re almost done! The last step is to clean up any debris or materials that may be left over from the installation process. Be sure to dispose of all materials properly.


    Installing ice and water barrier on your roof is an important step in protecting your home from water damage. By following these simple steps, you can ensure that your roof is properly sealed and protected.
