The Importance of Correctly Installing Ice and Water Shield in Cold Weather

Most people who live in Wisconsin can appreciate why their home’s roof needs an ice and water leak barrier. Without an ice and water shield installed, ice dams, wind-driven rain, and snow buildup can lead to costly home repairs.

Unfortunately, it takes more than just having leak barrier installed on your home’s roof to prevent weather damage to your home. You need to make sure the ice and water barrier is installed correctly.

Cross section of roof layersWhat is an ice and water shield?
It’s a rubberized, waterproof underlay. These shields provide a protective barrier to vulnerable areas of your roof, and they prevent leaks due to damaging ice dams and other extreme weather conditions.

Where on the roof does this shield go?
This shield is placed on top of the wood sheathing and under the shingles on your roof. It should be installed behind the gutter and over the top of the fascia board, eliminating the gap between the fascia board and first roof board. When installed correctly, the ice and water shield will extend up the roof from the fascia board to a minimum of 2” past the exterior wall. This kind of placement ensures that the shield protects your roof against leaks and prevent ice dams from forming along the edge of your roof or gutters which are most vulnerable during the winter.

Who needs to have ice and water shields?
In the northern part of the United States where the average temperature in January is 25 degrees or lower, most building codes require protection against ice dams.
