How do metal valleys and Ice and water shield Stop Ice Dams

Updated: Mar 17, 2020

Ice dams on roofs are quite common, but when left unattended, they can lead to costly leaks and damage:

If an Ice dam is present, it’s essential to have the ice dams removed professionally and quickly. However, the best course of action is to invest in ice dam prevention. Two very important materials for Prevention are valley metal and ice & water shield.

What is an Ice Dam:

Ice dams are formed by the continuous melting and freezing of snow due to heat escaping from the house. The melted water flows under the snow and freezes as it reaches the unheated soffit area, thus creating an ice dam. When this occurs, water can be forced under the shingles and into the attic, resulting in damage to the home’s interior.

What is Ice & Water Shield:

Ice & Water shield is a waterproof underlayment membrane that was developed to protect a roof's most vulnerable areas from ice & water damage.

What Is a Metal Valley:

A roof valley is an area where two of the roof faces come together. It’s a common element of architectural design, creating different levels and heights to the home’s structure. However, because of its design, the valley can easily become the ideal place for water to pool. A metal valley is a pre-bent roofing material designed specifically to protect these areas of the roof. It’s placed on top of an ice and water shield present in the valley. As a barrier, it helps ensure the roof remains dry and protected even as temperatures change.

How Does a Metal Valley Provide Ice Dam Protection:

When you have an ice dam, roof materials tend to bend and flex to account for the ice. As water freezes, the ice expands, moving those materials out of alignment. This creates areas where water can leak leaks into the underlayment, putting your home at risk. Metal valleys can assist in preventing this from happening, they work to keep the roofing materials dry. Metal is the best choice for this as It lasts longer and is more durable. It’s also very versatile, which means it can be used in most areas where roof valleys exist.
