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. The perimeter attachment means is selected from: (a) a plurality of elongate membrane sheets that are position and attached to form at least one perimeter channel at each perimeter side of the roof; (b) at least on perimeter channel positioned and fastened along the perimeter sides of the roof parallel to the central region channels and fasteners bisecting the central field channels along all other perimeter sides of the roof; (c) fasteners or other attachment means bisecting the central region channels parallel to perimeter sides parallel to said central region channels and fasteners or other attachment means bisecting the central region channels perpendicular to the remaining perimeter sides of the roof; and (d) a fully adhered perimeter.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 069,434, filed on Mar. 14, 2008.FIELD OF THE INVENTION

[0002] This invention relates to an improved system and method for removing moisture from beneath a structural roof made with low permeability membranes or panels. This invention further relates to a system and method for improving the moisture, and hence mold, resistance of roof assemblies made from elongate sheets of membrane, including but not limited to polyvinyl chloride (PVC), ethylene propylene diene monomer (EPDM), modified bitumen, thermoplastic olefin (TPO), and / or other thermoplastic or thermoset materials.BACKGROUND OF THE INVENTION

[0003] In recent years, roofing systems using elastomeric membranes have become popular for many commercial structures, i.e., those having a predominantly flat rooftop. For many such applications, a suitable roof membrane is laid over the top surface of a roof substrat...
