Episode 3 of The Building Science FAQ series: What is a roof coating?

By GAF.

The Building Science FAQ video series explores some of the technical questions that crop up when specifying a low-slope roof.

In this episode, Jennifer Keegan, Director of Building and Roof Science, GAF, and Jim Kirby, Building and Roofing Science Architect, GAF, address a deceptively straightforward question: “What is a roof coating?” Answering that question requires an understanding of the many differences in use, benefits and application scenarios between roof coatings and liquid-applied roof membranes.

Did you know that a liquid-applied roof membrane is not the same as a roof coating? Each uses similar base materials but its important to pick the right solution for the roof scenario.

A roof coating is a fluid-applied adhered coating used for roof maintenance or repair or as part of an assembly and they are typically installed on an existing roof. Liquid-applied roof membrane is a roof membrane constructed in place using a liquid resin and fabric reinforcement. It’s applied directly over insulation, coverboard or existing roof membrane in a re-cover scenario.

Tune in to this latest episode of the GAF Building Science FAQ Series for an easy-to-understand session that explains the difference and the best use cases for each product.
