What is an Ice and Water Shield?

An ice and water shield is a thin underlayment layer employed to better protect the most vulnerable parts of your roof from the harshness of the outdoor elements. The layer is composed of rubberized asphalt and features a strong adhesive back surface that bonds to the roof deck. Water cannot pass through the tight seal it creates. 

Why Is It Important?

An ice and water shield is especially important if you live in an area with heavy moisture and cold weather. Below are some of the primary reasons why: 

An Effective Barrier to Moisture 

An Ice and Water Shield protects the roof deck from moisture and frost, by sealing exposed areas. This includes both the roof edges as well as any nail penetration when shingles are applied. Other applications include wrapping the base of chimneys, walls, valleys and other vulnerable penetrations. In addition, they serve as the second layer of surface protection should the shingles over it become compromised. 

Reduced Maintenance Cost 

Since an ice and water shield prevents water from seeping into your attic, it helps lower the risk of interior damage. Exposure to moisture can cause your roof deck or the interior of your home to rot. This can add up to frequent costly repairs and maintenance down the road. It’s not fun spending money that could have been avoided if an ice and water shield had been installed in the first place!

Where is an Ice and Water Shield Most Needed?

Ice and water shields are most needed in areas of the roof where the water is most likely to accumulate. These areas include the first 3 feet up the roof, under valleys, walls and other areas requiring extra care. In addition, it is also recommended to have them installed around the vent stacks, chimneys. Basically any feature that projects from the just receive an ice and watershield application. Shingles and flashings don’t cover them up completely, so it is important to make sure you are taking good care of the most vulnerable areas.
