Six-Year Conventional Roof Monitoring Report

A conventional roof research and field monitoring study was initiated by RDH Building Science Inc. (then RDH Building Engineering Ltd.) in partnership with Soprema and ROCKWOOL (then Roxul) in 2012. The purpose of this study was to better understand the performance of conventional roof assemblies and to evaluate the impact of roof membrane colour and insulation strategies. This final report presents a complete analysis of data collected over the course of six years, periodic field investigation findings and laboratory material testing results.
