Abstract: An improved system for removing moisture from a roof envelope made from low permeability membrane sheets that includes: a plurality of elongate membrane sheets positioned and attached, in adjacent rows, over a central region of the roof, to form central channels, with each channel having at least one one-way roof vent positioned near one end of that channel, and a perimeter attachment means.

Abstract: An anchoring system for securing an elastomeric membrane to the upper surface of a roof has a rigid anchoring plate which has a planar bottom surface, apertures to facilitate securing the anchoring plate to the roof, and a pair of raised reinforced sidewalls to aid in interlocking the device. A spacing insert is provided which employs a pair of flanges, a pair of horizontal lips, and a central hinge to snap into the anchoring plate after the membrane has been laid out over the anchoring plates. A planar wedge is also provided which includes a lip to facilitate inserting the wedge into, and withdrawing the wedge from, the spacing insert. A special fastening device is provided to secure the anchoring system to the roof surface. When the components of the present anchoring system are fitted together, an elastomeric membrane may be substantially immobilized. The structure of the device is also easily disassembleable, as may become necessary in order to inspect or service the elastomeric membrane.
