Roof Coatings

GAF is North America’s largest roofing manufacturer.
More homes and businesses in the U.S. are protected by a GAF roof
than by any other product.

Benefits of Coating a Roof

Our high-quality coatings provide a reliable way to protect, preserve, restore, repair and beautify low-slope structures.

They can help extend the life of structurally sounds roofs and can help add solar reflectivity properties to dark colored roofs, greatly reducing energy costs.

Types of Liquid-Applied Roofing

GAF offers multiple liquid-applied roofing system solutions, each designed for specific applications and conditions. These solutions each feature a liquid-applied component that creates a seamless, chemically resistant barrier to external elements. They can be installed over most existing roof types, eliminating the need for tear-offs.


Primers assist your roof coating project by providing better adhesion, better stain blocking, and an overall better performing coating system. With the ability to install via roller, brush, or sprayer, GAF primers offer ease of installation.


Elastomeric acrylic roof coatings provide excellent durability and can be installed over existing modified bitumen, built-up, concrete, metal, or single-ply installations. These coatings are reflective and very easy to install and maintain.


Silicones provide superior weatherproofing, ultraviolet resistance, and resistance to biological growth that helps protect against damages from ponding water. Silicone roof coatings also “chalk” less than standard acrylics decreasing the time required between recoatings. These products are often used in high-moisture climates for their fast-drying characteristics.


GAF has a full line of accessory products to meet the needs of many different roof types. Effectively repair and reinforce seam, details any other vulnerable areas on the roof with one of GAF's roof coating accessories.
