What is ice and water shield?

Ice and water shield is a self-adhered waterproof membrane. It was developed to fight ice damming and wind-driven rain.   Therefore, it is commonly used up north on the eaves of the roof to protect damages from ice build-up.  Baker Roofing & Construction uses ice & water shield on every roof replacement with valleys, chimneys or skylights.  The use of ice & water shield in leak-prone areas of the roof increase protection from water damages in the most severe weather.
