Predictive Service Life Tests for Roofing Membranes: Phase 1
Abstract
The Army and roofing industry have extensive field experience with roofing membranes. Roofing manufacturers, however, have been changing the composition of the membranes and introducing new materials at an increasing pace. Despite the initial satisfactory rating of some of the new products, their long-term durability is unknown. Army roofing managers need reliable tests to predict the durability of roofing membranes. The objective of this study was to characterize roofing membrane material based on in-service performance requirements and criteria, and to identify degradation factors and mechanisms that can be used to propose accelerated aging tests for service life prediction of roofing membranes. This study determined that existing criteria and measurements for performance testing are inadequate. Predictive service life tests should be developed based on physical and chemical degradation measured after accelerated aging tests in a variety of climates. Degradation modeling and standard test methods should be incorporated into the test process. Built-up roof, Roofing membranes, Predictive maintenance.
