What is Ice and Water Shield?
Ice and Water Shield is a specialized underlayment used in roofing that provides a superior level of protection against water infiltration caused by ice damming and severe weather conditions. Made of a rubberized asphalt material, this product is typically installed on the lower edges of the roof, around chimneys, and in valleys to safeguard against leaks. At John M. Shinn Roofing, we incorporate this crucial element in our installations to enhance the durability and effectiveness of the roofing systems we offer.
Why is Ice and Water Shield Essential for Your Roof?
The primary function of Ice and Water Shield is to prevent water damage. It's important to understand the following reasons why this product is indispensable:
Protection Against Ice Dams: Ice dams occur when melting snow refreezes at the edge of the roof. The resulting ice block causes water to back up and seep under shingles. Ice and Water Shield acts as a barrier, ensuring that any water that penetrates is safely directed away from your home.
Enhanced Sealant: The product possesses a self-adhesive quality that allows it to form a strong bond with the roof deck. This adhesion helps seal the roof, minimizing the chances of leaks and enhancing structural integrity.
Added Durability: Ice and Water Shield is resilient to various elements, including UV rays and extreme temperatures, making it a long-lasting solution that protects against the wear and tear of local weather conditions.
Where Should Ice and Water Shield Be Installed?
To maximize its effectiveness, here are the critical areas where Ice and Water Shield should be installed:
Along roof eaves, particularly in regions prone to ice buildup.
Around roof penetrations such as chimneys and vents that are susceptible to water intrusion.
In roof valleys where water flows together and can create concentrated areas of infiltration.

The Role of Professional Installation
