What is an Ice and Water Shield?
An Ice and Water Shield is a type of roofing underlayment that is designed to protect a roof from water damage caused by ice dams and wind-driven rain. It is typically made from rubberized asphalt and has a high adhesive strength, which helps it adhere to the roof decking.
What is the purpose of an Ice and Water Shield?
The purpose of an Ice and Water Shield is to create a watertight barrier between the roof decking and the shingles or other roofing material. It is designed to prevent water from entering the roof system and causing damage to the structural components of the roof, such as the roof decking, insulation, and rafters. Additionally, it helps to prevent ice dams from forming along the eaves of the roof, which can cause significant water damage to the interior of a home.

What makes Ice and Water Shield different from traditional felt underlayment?
Traditional felt underlayment is typically made from organic or fiberglass materials and is designed to provide a secondary layer of protection against water infiltration. While felt underlayment is effective at preventing water penetration, it does not have the same adhesive strength or flexibility as an Ice and Water Shield. This means that it may not be as effective at preventing leaks caused by wind-driven rain or ice dams.
When should Ice and Water Shield be used?
Ice and Water Shield should be used in any area of the roof where there is a potential for water infiltration, such as along the eaves, valleys, and around roof penetrations like skylights and chimneys. It is recommended for use in regions that experience heavy rainfall, snowfall, or freezing temperatures.
Can Ice and Water Shield be installed over an existing roof?
While it is possible to install Ice and Water Shield over an existing roof, it is not recommended. This is because the existing roof may have underlying issues that could compromise the effectiveness of the Ice and Water Shield. Additionally, installing Ice and Water Shield over an existing roof may not be allowed by local building codes.
How is Ice and Water Shield installed?
Ice and Water Shield is typically installed in narrow strips along the eaves, valleys, and around roof penetrations. The strips should be overlapped by several inches in order to create a continuous watertight barrier. The Ice and Water Shield should be installed directly onto the roof decking, with the shingles or other roofing material installed over the top.
Does Ice and Water Shield require any special maintenance?
Ice and Water Shield does not require any special maintenance. However, it is important to inspect the roof periodically to ensure that the Ice and Water Shield is still properly adhered to the roof decking and has not been damaged or torn due to wind or other weather-related events.
What is the lifespan of an Ice and Water Shield?
The lifespan of an Ice and Water Shield depends on the quality of the product, as well as the local climate and other environmental factors. While some manufacturers offer warranties of up to 30 years, most Ice and Water Shields will last between 10 and 15 years.

Is it necessary to use Ice and Water Shield?
While it is not always necessary to use Ice and Water Shield, it is highly recommended in areas that experience heavy rainfall, snowfall, or freezing temperatures. Additionally, many building codes require the use of Ice and Water Shield in certain areas of the roof, such as along the eaves and in valleys.
