Established in 1886, the National Roofing Contractors Association (NRCA) is one of the construction industry’s oldest and most respected trade associations and the voice of professional roofing contractors worldwide. NRCA provides a variety of resources to help home and building owners make informed decisions about replacing and maintaining their roofs. These include an online membership directory that allows consumers to search for member roofing contractors by zip code, as well as a searchable technical database and glossary of roofing terms.
