Ice & Water: Why You Need It and Why It’s Important

Can you identify the ice and water in this photo? Ice and water protection products, often referred to as ice and water shield or underlayment, are designed to create a watertight barrier on the roof. They are important elements of a roofing system because they play a crucial role in protecting your roof from water damage and leaks. Here are a few reasons why ice and water protection is essential to you and your roof repair or roof replacement.

For weather proofing, ice and water is particularly important in regions that experience cold winters, where ice and snow can accumulate on the roof and create the potential for ice dams and leaks.

Ice dams occur when snow on the roof melts due to heat from the interior of the building or sunlight and then refreezes near the eaves of the roof, creating a barrier for water to escape. Ice and water protective shields help prevent the melting water from infiltrating the roof structure, reducing the risk of ice dam formation.

Ice and water act as leak prevention. Ice and water is an additional layer of defense against roof leaks. It provides a waterproof seal around critical areas such as valleys, eaves, roof penetrations (chimneys, vents), and roof-to-wall transitions, reducing the risk of leaks during heavy rain or snowmelt.

Proper ice and water protection can extend the lifespan of a roof by safeguarding it against moisture damage. It helps to maintain the integrity of the roofing materials and to reduce the need for costly repairs.

Many building codes and regulations require the installation of ice and water protection on roofs, especially if the roof has a lower pitch and if the home is in an area prone to winter weather conditions. Compliance with these codes is essential for the safety and durability of the roof.

Some insurance companies may offer discounts or require the installation of ice and water protection as a condition for coverage. Having such protection in place can also make it easier to file a claim in the event of roof damage.

In summary, ice and water protection is crucial for maintaining the integrity and longevity of a roof. It helps prevent water intrusion, ice dam formation, and subsequent damage to the building’s structure and interior. Proper installation of ice and water protection is an important component of a well-built and weather-resistant roof system.
