Abstract

A venting system for allowing the escape of harmful water vapors trapped in the roof system. The system includes a roof deck forming the base of the roof system, a roofing membrane positioned over the roof deck, and a channel network positioned between said roof deck and said roofing membrane to form a plurality of venting passages below said membrane. The channel network comprises a plurality of integrally formed channel members arranged to form a grid covering the roof deck. The cross section of the channels is shaped as an inverted trough, thereby providing sufficient strength to the network's surface to support the outer roof treatment and/or to permit an installer to walk across the surface of said network without collapsing it. Roof vents pierce the roofing membrane and provide a relief passage communicating with the venting passages. Water vapor trapped beneath the roofing membrane is channeled through the venting passages to the roof vents where it evaporates into the atmosphere.
