ICC Evaluation Service (ICC-ES) LLC has developed guidelines for evaluating alternative asphalt shingles. These criteria provide an alternative to using ASTM D3462, "Standard Specification for Asphalt Shingles Made from Glass Felt and Surfaced with Mineral Granules," which is a requirement for fiberglass-reinforced asphalt shingles in the International Building Code® (IBC) and International Residential Code® (IRC).
If you are involved with the installation or design of asphalt shingle roof systems, I encourage you to be aware of these alternative provisions.
ICC-ES is a nonprofit subsidiary of the International Code Council (ICC), which develops the IBC. ICC-ES provides technical evaluations of building products, components, methods and materials for use by manufacturers as evidence their products meet code requirements and warrant regulatory approval. ICC-ES' evaluations are particularly useful for evaluating products that may not comply with established standards, including evaluating new or innovative products, with the intent of complying with building codes.
