GAF Roof Mate™ Base Coat is a water-based acrylic elastomer base roof coating utilizing the latest advances in acrylic technology. It is a “breathable” base coat, allowing moisture vapor to pass through the film while remaining resistant to mass water penetration. Roof Mate™ Base Coat helps improves adhesion of the top coat on most substrates and provides bleed blocking on asphalt roofs. It builds a film thickness necessary to protect the roof, and therefore it counts as the first coating layer.

Why United Coatings™ Roof Mate™ Base Coat?

United Coatings™ Roof Mate™ Base Coat utilizes the latest advances in acrylic technology to improve adhesion of United Coatings™ Roof Mate™ Top Coat and to provide bleed blocking on asphalt roofs.

  • How to Install the GAF Roof Mate Coatings System | GAF Roofing
    Roof coatings are a great way to extend the life of your low-slope or flat roof. They protect the roof from wind, rain and sun that can cause a roof to dry out and crack and can provide energy savings by lowering the temperature of the roof. Before you coat the roof, replace any wet insulation and address any ponding water areas. Once the roof is sound, you are ready for the Roof Mate System. The Roof Mate System includes all the components needed to restore the roof. The system includes Roof Mate Base Coat, Top Coat, Butter Grade Flashing, Fabric and Seam Tape. The Roof Mate Coating System can be used directly on most metal, asphaltic, and single ply roofs.
