Why you need Ice and Water Barrier

First off – Yes! You NEED Ice and Water Barrier if you live in Iowa.
Ice and Water Barriers are mandatory for all roof replacements in Iowa! There is a National Code that says that because we live in an area that gets below 25°F (3.8°C), there is a possibility of ice forming on the eaves of your home – that means that there is a risk of water and ice coming into your home until it is protected in vulnerable areas.
What does Ice and Water Barrier do?
I&W (Ice and Water Barrier) at the most vulnerable areas of your roof (at the eaves and rakes, in valleys, around chimneys, etc.) will help prevent leaks due to water backing up in your gutters, wind-driven rain, and limit damage from ice dams. It will also protect your home from expensive wall and ceiling staining from leaks.
We prefer to use an Ice and Water Barrier with fiberglass reinforcement – this helps resist wrinkling and buckling.  GAF Weather Watch is Miami Dade (Highest Rating level) approved. Using this product along with others in a GAF roofing system and Roof Iowa being one of the highest certified companies as a Master Elite, we can get your home THE BEST warranty for a roof.  Best Roofer + Best Products = Best Warranty!
