The National Roofing Contractors Association has released NRCA Guidelines for the Application of Roof Coatings. The new guide updates the 2015 guide and serves as a reference for roof coating designers and installers.
The guide provides technical information about the application of various types of roof coating systems, preparations necessary for their successful performance and quality control guidelines for on-site evaluation. Also included are best practice guidelines for the application of common roof coatings to various types of roof surfaces, such as membrane roof systems or existing coating systems.
The guide has been reorganized to more closely follow the chronological order of events surrounding the roof coating process, and terms and definitions have been modified, added or removed to better capture the wide range of applications currently available for roof coatings. Step-by-step guidance on some quality control and quality assurance procedures also have been added.
Hard copies of NRCA Guidelines for the Application of Roof Coatings are available at nrca.net/shop. NRCA members can download the guide for free in electronic format.
