What is ice/water shield underlayment?

A Peel and Stick” underlayment is a self-adhering underlayment sheet used to waterproof critical areas on the roof deck. For example, the Atlas WeatherMaster line of peel and stick underlayments are all self-adhering and seal around all the fasteners driven through during the completion of the roof covering installation – kind of like a “drive flat tire” – as the self sealing feature does it’s job.
