Roofing Materials and Systems, AARM


Roofing materials and systems are investigated for protection from external fire exposure. Roof deck assemblies are investigated for performance under internal fire exposures and for uplift resistance.

These materials are intended for use only in specific construction designs as described in the general Guide Information for each product category and individual certifications. The use of the materials in conditions other than described in the instructions, markings and the general Guide Information for the applicable product category has not been investigated by UL.


The scope of product sizes and ratings appearing in the general Guide Information for some product categories is intended to indicate the current range of certified products, however, it is not necessarily indicative of limitations for those certified products.

The standards used to investigate products are identified in the general Guide Information for each product category. There may not always be a published standard for investigating a product to determine its acceptability for certification. If no applicable standard is available, UL will exercise its judgment in the selection of applicable requirements from related standards and other sources to develop the requirements to cover uses and conditions for which specific requirements did not previously exist.

Products, equipment and construction materials certified by UL in accordance with international or regional standards only (e.g., products certified to an IEC or ISO standard) are intended for distribution, installation and use in areas of the world where the specified standards have been adopted and are in effect as national or regional standards.


The limitations for the equipment as specified in the general Guide Information for each product category such as voltage and temperature limits, markings, special descriptions and installation provisions need to be noted prior to installation and use.

Equipment has been investigated with reference to risks to life and property and for conformity to the installation and use provisions of the applicable installation codes and standards of the National Fire Protection Association (NFPA), and applicable model codes identified in the general Guide Information for each product category.

Some products are certified for uses not within the scope of nationally recognized installation codes and standards. Such products are investigated for the specifications or use conditions indicated in the general Guide Information for each product category.

These products are intended for installation subject to approval by the Authority Having Jurisdiction. Authorities Having Jurisdiction should be consulted before installation.


These products are intended to be installed in accordance with the installation instructions provided with the product. It is critical that the cautionary statements and installation and operating instructions on the product and in accompanying literature be followed.
