Elastomeric roof coatings play a vital role as the surfacing component in two-part spray polyurethane foam-based (SPF) roofs. For further information about the substrate for SPF roofing systems, you can refer to our polyurea foam page. Additionally, elastomeric roof coatings find common usage in protecting metal roofs.
The application of elastomeric roof coatings brings numerous benefits to the roofing systems they cover, notably by promoting energy efficiency and enhancing durability. Qualified roofing contractors can easily apply elastomeric coatings, often utilizing spray application. Nevertheless, the American Society for Testing and Materials (ASTM) acknowledges that hand and power rollers can also be utilized for application. Your roofing contractor will be knowledgeable enough to guide you towards the appropriate application method for your facility’s roofing system.

Qualified roofing contractors can conveniently apply elastomeric coatings, often employing spray application methods. Nevertheless, it’s worth noting that the American Society for Testing and Materials (ASTM) also recognizes the feasibility of utilizing hand and power rollers for application. Your roofing contractor will possess the necessary expertise to guide you toward the most suitable application method for your facility’s roofing system.
Standards for elastomeric roof coatings
The National Roofing Contractors Association strongly advises that all elastomeric roof coatings meet the standards established by ASTM. Among these standards, ASTM D6947 specifically governs coatings utilized in SPF roofing systems, including elastomeric polymer coatings. To meet the benchmark set by ASTM, elastomeric roofing coatings must successfully pass a series of rigorous tests, assessing tear resistance, water absorption, and temperature resistance. These tests are designed to ensure the high quality of elastomeric roofing coatings that comply with the ASTM D6947 standard. A reliable roofing contractor will be well-informed and capable of directing you to coating manufacturers that adhere to this and other relevant ASTM standards concerning elastomeric coatings.
