A quest for clarity
A new NRCA task force is reviewing manufacturers' installation instructions


As roofing products and roof systems become increasingly proprietary and complex, proper installation instructions are an important consideration. Roofing product and roof system manufacturers generally are responsible for providing users with instructions explaining how to properly install their products.

Instructional variance

Although some manufacturers make their product-specific installation instructions readily accessible to users, instructions for some products are difficult to locate and not written at a level appropriate for the intended users—field applicators.

Most asphalt shingle manufacturers, for example, imprint product-specific installation instructions on shingle bundle wrappers. Some manufacturers print instructions in multiple languages in recognition some installers may not speak or read English.
