For Metal
This collection groups GAF products approved for metal substrates. Metal roofs vary by alloy and finish, so the primer choice matters: GAF Metal Roof Primer for rusty steel, GAF Bonding Primer or Multi-Purpose Primer for non-ferrous metals (aluminum, copper, galvanized), and direct-bond options for Kynar-coated panels.
For the full restore system breakdown (HydroStop Premium Acrylic with Spray-Grade Acrylic Flashing for seams, or High Solids Silicone for metal roofs that pond), see the Over Metal collection. Each system carries 10-, 15-, or 20-year warranty terms depending on coverage rate. Factory-direct from a GAF-authorized distributor.
