NRCA's most frequently asked technical questions are answered

Every day, NRCA's Technical Services Section responds to requests for technical assistance. About 20 percent of the requests come from homeowners, and a substantial number of requests come from roofing contractors with concerns about issues homeowners are facing. In many cases, roofing contractors contact NRCA to inquire about NRCA's position on a specific topic, or they are looking for documentation to substantiate their positions. Following is an assortment of NRCA's most frequently asked questions.

What is the best asphalt shingle?

NRCA cannot recommend specific products and/or manufacturers. Asphalt shingle material performance depends on the quality, quantity and compatibility of asphalt, fillers, reinforcements and surface granules. Asphalt shingles should comply with ASTM International standards and applicable building codes. Fiberglass asphalt shingles should meet ASTM D3462, "Standard Specification for Asphalt Shingles Made from Glass Felt and Surfaced with Mineral Granules."

NRCA often is asked whether there are other third-party organizations that evaluate asphalt shingles. In June 2009, Consumer Reports magazine provided ratings for 26 popular asphalt shingle products. Although Consumer Reports is recognized for providing useful information to help consumers select products, NRCA is concerned its article addressing asphalt shingles will mislead homeowners.
