Abstract:
A roofing system having preferred metallic roofing panels overlying a roof structure or a substrate (such as a waterproof membrane) includes a mat of loosely-woven ventilation mesh material between the panels and the roof structure or substrate in order to provide proper ventilation, thus minimizing corrosion resulting from condensed moisture. The mesh is preferably composed of an extruded thermosetting plastic material.
