The Case to Use Grace Ice & Water Shield® - it is Watertight

By Cass Jacoby, RCS Reporter.  

This durable and easy-to-install product ensures the job is done right the first time. 

We all know the importance of keeping moisture out of your home, be it rain or snow, and leaks around roof fasteners which can cause quite a headache for homeowners. Luckily, GCP Applied Technologies has a solution that maintains a tight seal for better adhesion on roofing jobs: Grace Ice & Water Shield®. 

"Grace Ice & Water Shield® has the best adhesion to the roof deck," one Wisconsin contractor who uses the roofing underlayment told Amerhart. "You will not have problems with ice damming, leaks, wind-driven rain… anything like that." 

Grace Ice & Water Shield® is made out of rubberized asphalt, a tested and proven proprietary material that provides the highest level of waterproofing performance. Its watertight seal offers superior protection from the elements and keeps the roof clean and dry.  

Because it doesn't have a granular finish, the adhesive seals to itself around roofing fasteners through the membrane forming strong, watertight laps. "That's the best advantage of [Grace Ice & Water Shield®] right there," Wisconsin jobsite construction lead Justin Borgwardt told Amerhart. 

These are just a few reasons why Grace Ice & Water Shield® is the trusty waterproofing product contractors have sworn by for over 40 years. The product can be used on both new projects and repairs to make for a roof that stands strong against the elements.
