Critical Barrier for Vulnerable Areas
Unlike standard underlayments, ice and water shield (often called “leak barriers”) features adhesive backing protected by peel-off membranes for self-adherence to the roof deck. These materials offer rubber-like properties that self-seal around fasteners including nails and staples, creating watertight barriers at critical roof areas.
Building codes and manufacturer guidelines recommend installing these waterproof underlayments at eave edges, in all valleys, and at vulnerable roof areas including low-slope sections and flashing junctions.
