scope:

This standard applies to liquid applied products with or without reinforcements that are applied over existing, functioning certified roof systems. Certified roof maintenance coatings must be used in conjunction with previously installed certified roofs. Maintenance coatings do not increase the fire, wind, leakage or hail resistance performance of the existing roof.

This standard is intended to evaluate only those hazards investigated and is not intended to determine suitability for the end use of a product.

This standard shall not be used to qualify roof cover products.

Purpose

This standard states testing and certification requirements for roof maintenance coatings.

Testing and certification criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a surveillance program.
