Experimental Polyvinyl Chloride (PVC) Roofing: Field Test Results.
Abstract
Results are reported for the first 2 years of a 10-year field test on three polyvinyl chloride (PVC) roofing systems. At the time of installation, the roofs were tested for initial properties to provide a basis for comparison with later samples. Test samples of each roof are taken at 6-month intervals and the samples section is patched. Properties evaluated are those considered essential to good roofing performance; they are tested using American Society for Testing and Materials (ASTM) standard methods in most cases. In addition, the roofs are inspected visually once each year. Preliminary findings indicate that the PVC systems tested have remained relatively unchanged in terms of physical and mechanical properties. At this point, all roofs appear to be performing at a satisfactory level. Some characteristics, such as fungal growth shrinkage, and streaking, will need careful scrutiny over the next few years to learn if they affect overall roof performance. A Corps of Engineers Guide Specification (CEGS) has been developed based on these results. The CEGS allows the Army to specify, within limits, certain PVC roofing systems for military construction.
