Abstract
While IBHS evaluates fourteen products across seven manufacturers weathered at its regional aging farms, the report’s sweeping conclusions are fundamentally compromised by non-standard testing protocols, unrepresentative grab-sampling, and incomplete probabilistic modeling. By shifting testing procedures mid-project and omitting positive performance outcomes along with enhanced manufacturer installation guidelines, the study fails to reflect real-world roof system durability.
