Ice and Water Protector: What Is It and Where Does It Go?

Removing snow from the roof

When it comes to protecting your home from leaks and water damage, an ice and water protector is a critical component in your roofing system. This underlayment layer provides essential defense against moisture infiltration, particularly in vulnerable areas of your roof. In this article, we’ll explain what ice and water protectors are, their benefits, and where they should be installed for maximum effectiveness.

What Is an Ice and Water Protector?

An ice and water shield, also referred to as an ice and water protector, is a specialized, self-adhesive waterproof underlayment used beneath roof shingles to prevent water from seeping into the roof deck. The material is typically made up of rubberized asphalt, which adheres directly to the roof’s surface, forming a watertight seal. This helps safeguard the home from potential leaks that may occur when the roof’s shingles are not enough to stop water from penetrating.

The purpose of an ice and water shield on a roof is to act as a barrier against water infiltration, particularly in areas susceptible to water damage. This includes places where ice dams form and wind-driven rain can drive water under the shingles. Ice dams strike when melting snow refreezes at the edge of the roof, trapping water that can back up under the shingles and into the roof deck. Ice and water protectors are specifically designed to prevent this type of damage, offering extra protection in harsh weather conditions.

Benefits of Using Ice and Water Protectors

The primary benefit of ice and water protectors is their enhanced waterproofing capability. They help prevent leaks in critical areas, thus protecting the home’s structure from water damage. A key feature of ice and water roofing is that the material can seal around fasteners, such as nails or screws, significantly reducing the chances of water infiltration through these penetration points.

In addition to waterproofing, ice and water shields add a critical extra layer of protection against varying weather conditions. Whether your roof is facing heavy snow, ice, or wind-driven rain, the ice and water shield for roofing offers an extra defense. This added layer helps prolong the life of your roof by preventing damage that could lead to rot, structural issues, or the need for costly repairs over time.

Where Should Ice and Water Protectors Be Installed?

Certain areas of the roof are more vulnerable to leaks and water damage, making them prime candidates for an ice and water shield roof installation. The most critical areas include the eaves and valleys.

  • Eaves (roof edges) are where ice dams typically form, creating a risk of water backing up under shingles. By installing an ice and water protector here, you prevent water from infiltrating the roof structure.
  • Valleys, where two roof planes meet, experience heavy water flow and are another high-risk area for leaks. The use of an ice and water shield in these areas helps secure the roof from water damage.

Another important place to install an ice and water shield is around roof penetrations like chimneys, skylights, and vents. These features can allow water to seep in through gaps, but a water and ice shield provides a critical barrier, sealing off these potential weak points. Similarly, it should be used around flashings and dormers, where the roof meets walls or other vertical structures.

In areas with low-slope roofs, water drainage can be slower, increasing the risk of leaks. The application of an ice water shield in these spots is essential to protect against water infiltration. Installing the protector along ridge lines can also guard against leaks caused by wind-driven rain.
