Abstract
The classification of roofing products by Underwriters Labs is a complex and often perplexing topic. It can leave contractors asking such questions as: How important is UL labeling and classification of roofing membranes?; What criteria is used to determine which UL classification will be awarded to a membrane product?; Why do some roofing manufacturers display the UL on their product packaging while others don't?; How can I achieve maximum protection for myself and my customers? For the contractor or specifier who wants to comply with codes and standards, these are important questions. They must be answered before any roofing materials are purchased to ensure that materials meeting these standards will be used.
