Asphalt shingle material performance depends of the quality, quantity and compatibility of asphalt fillers, reinforcements and surface granules. There are two kinds of asphalt shingles (based on the type of reinforcement mat used); fiberglass and organic. Fiberglass shingles are more fire- and moisture-resistant than organic shingles. Organic shingles have good wind resistance, high tear strength and can be installed in colder temperatures.
Asphalt shingles should be in compliance with American Society for Testing and Materials (ASTM) standards and applicable building codes. Fiberglass shingles should meet ASTM D 3462, “Standard Specification for Asphalt Shingles Made from Glass Felt and Surfaced with Mineral Granules,” and organic shingles should meet ASTM D 225, “Standard Specification for Asphalt Shingles (Organic Felt) and Surfaced with Mineral Granules.”
Consumers also should keep in mind a roofing warranty’s length should not be the primary criterion in the selection of a roofing product or roof system because the warranty does not necessarily provide assurance of satisfactory roof system performance. See NRCA’s consumer advisory bulletin addressing roofing warranties for more information.
