If you’re a homeowner in need of a roof replacement, you may have heard about the importance of using Ice and Water Shield during the roofing process. But what exactly is Ice and Water Shield, and why is it considered a must-have for your new roof? 

What is Ice and Water Shield?

At the heart of a well-protected roof lies the Ice and Water Shield, a self-adhering waterproofing barrier that significantly enhances the resilience of your roofing system against moisture. Crafted from a rubberized asphalt compound, this shield integrates a potent adhesive backing, designed to firmly secure itself to the roof deck. 

The innate properties of Ice and Water Shield, notably its self-sealing capability around nail penetrations, represent a significant advancement over older, traditional moisture barrier solutions, offering homeowners peace of mind and an enhanced level of protection. This modern roofing marvel is not just a layer of security; it’s a critical investment in the longevity and durability of your home’s roofing infrastructure.

What Does Ice and Water Shield Do?

Ice and Water Shield serves as a critical component in the roofing system, offering unparalleled protection against water damage and water infiltration. It also mitigates ice dams and wind driven rain, prevents leaks, and extends the roofs lifespan. 

Prevents Water Damage

Ice and Water Shield offers unparalleled protection against water damage, addressing vulnerabilities where water is most likely to penetrate, such as at the eaves, valleys, and around roof penetrations. By forming a watertight seal directly on the roof deck, Ice and Water Shield effectively prevents water from infiltrating under shingles and compromising the structural integrity of the roof.

Increases the Lifespan of Your Roof

Its application by reputable roofing contractors ensures that every potential entry point for water is securely protected, providing homeowners with added security against the elements and extending the life of the roof.

Mitigates Ice Dams

Ice and Water Shield is particularly vital in areas susceptible to ice dams and wind-driven rain, where water can be forced upward and underneath roofing materials. Its presence significantly reduces the risk of leaks that can lead to interior damage, mold growth, and insulation deterioration, acting as a proactive measure against unforeseen repair costs..

The Three Different Types of Ice & Water Shield

Ice and Water Shield comes in various types, each offering distinct advantages tailored to specific roofing needs. The three most common types of ice and water shield include asphalt-based, rubberized asphalt, and synthetic polymer.


Consists of an asphalt membrane that is backed by a strong adhesive. It adheres tightly to the roof deck and forms a waterproof barrier. Asphalt-based Ice and Water Shield is commonly used in roofing applications due to its effectiveness and relatively low cost.

Rubberized Membrane

Similar to the asphalt-based variety, this type of Ice and Water Shield is made of a rubberized asphalt compound. It offers excellent flexibility and can conform well to the contours of the roof, providing superior protection against water infiltration.

Synthetic Polymer

This type of Ice and Water Shield is made from synthetic materials such as polyethylene or polypropylene. Synthetic membranes are lightweight, durable, and resistant to tearing and punctures. They offer excellent waterproofing properties and are often used in areas with extreme weather conditions.

Factors like climate, budget, and project requirements are key in selecting the right one. Asphalt-based options are cost-effective and effective, rubberized asphalt provides flexibility, while synthetic polymer membranes offer durability, particularly in harsh weather. These considerations empower homeowners to make informed choices for their roof protection.

Long-Term Benefits of Installing Ice and Water Shield

Opting for Ice and Water Shield for your roofing system offers a range of benefits extending beyond mere water damage prevention. It lessens repair needs, enhances energy efficiency, and provides peace of mind for those who opt for its installation.

Reduced Repair Frequency

Ice and Water Shield protects the deeper layers of your roofing system like decking. By maintaining the roof’s integrity over time, Ice and Water Shield reduces the need for costly and inconvenient repairs, saving homeowners money and hassle.

Improved Energy Efficiency

The shield acts as an additional layer of insulation, helping to maintain consistent internal temperatures and potentially lowering heating and cooling costs, especially beneficial in climates with extreme temperature fluctuations.

Overall Peace of Mind

It provides a second line of defense against water and ice. Knowing that the home is protected against water damage and its consequences provides homeowners with peace of mind, making it a investment in the long-term health and safety of the property.

As homeowners embark on roof repair, replacement, or maintenance projects, being aware of regional variances in roofing costs is paramount. Consulting with local roofing companies familiar with the specific challenges of your area ensures accurate cost estimation and the implementation of solutions tailored to your region’s unique requirements. By factoring in these regional considerations, you can make well-informed decisions that align with both your budget and the specific needs of your home.
