Problems Prompt a Quest for High Quality Standards


Roofing problems can be traced to a lack of standards, inadequacies in standards, non-conformance to or non-enforcement of standards. It follows that the occurrence of certain problems can be reduced or eliminated by producing appropriate, quality standards that are adhered to by the specified products. Five case studies are examined that focus on roof performance problems dealing with specific roofing materials described by ASTM standard specifications.

Suggestions are offered for revising specific standards by adding requirements based on available research results. Packaging and labeling requirements as well as precision and bias statements are also discussed.
