How to Properly Install an Ice and Water Barrier 3

Understanding the Purpose of an Ice and Water Barrier

An ice and water barrier is an essential component of any roofing system. This barrier helps to prevent water from seeping through the roof and causing damage to the interior of the building. During winter months, ice dams – large icicles that form on the edge of a roof – can back up water that can eventually find its way into your home. When properly installed, an ice and water barrier can prevent this from happening.

Selecting the Right Ice and Water Barrier for Your Roof

There are several types of ice and water barriers available on the market. The most common types are self-adhering and mechanically attached. Self-adhering barriers are usually made from rubberized asphalt and are applied directly to the roof sheathing. Mechanically attached barriers are fastened to the roof using special screws or nails. The type of barrier you choose will depend on the climate in your area as well as the type of roof you have.

Knowing How Much Ice and Water Barrier You Need

The amount of ice and water barrier you need will depend on the slope of your roof. For a low-slope roof, you will need a full-width layer of barrier at the eaves and in the valleys. You will also need to cover any protrusions such as vents, chimneys, and skylights. For a steep-slope roof, you will need to cover the eaves, valleys, and other areas where water may penetrate the roof system. Consult a professional to get an accurate estimate of how much barrier material you will need for your roof.

Proper Installation Techniques for Ice and Water Barrier

The proper installation of an ice and water barrier is critical to its effectiveness. Here are some general guidelines for installing an ice and water barrier:

  • Clean the roof surface thoroughly before installing the barrier.
  • Start at the eaves and work your way up the roof.
  • Overlap each layer of barrier by at least three inches.
  • Ensure that there are no wrinkles or bubbles in the barrier.
  • Seal any seams or tears in the barrier using roofing cement.
  • Install metal flashings around any protrusions such as vents, chimneys, and skylights.
  • Use proper safety equipment when working on a roof, including safety harnesses and non-slip shoes.
  • Common Mistakes to Avoid When Installing an Ice and Water Barrier

    When installing an ice and water barrier, there are several common mistakes that homeowners should try to avoid:

  • Failure to properly clean the roof surface before installing the barrier.

  • Failure to install proper metal flashings around protrusions.
