Most roofs in the United States use asphalt shingles as the roofing material of choice. Shingles can be purchased in a variety of colors and coatings. The benefits of shingle roofs include cost, low maintenance, weather resilience and easy installation. However, the life of asphalt shingles is the lowest of all materials. The NRCA recommends use of shingles that comply with American Society for testing and Materials (ASTM) standards: ASTM D 225 for organic shingles and ASTM D 3462 for fiberglass shingles. Not all asphalt shingles on the market comply with these standards - it is typically noted on the manufacturer's product literature and on the package wrapper.
