What Paint Will Stop Rust on Metal Roofs?

What Paint Will Stop Rust on Metal Roofs?

Metal roofs are known for their durability, but over time, exposure to moisture and oxygen can lead to rust, compromising both aesthetics and structural integrity. If you're looking to protect your metal roof and stop rust in its tracks, choosing the right paint or coating is essential. Fortunately, Nationwide Protective Coatings offers a range of high-performance solutions specifically designed for this purpose.

One of the most effective products for protecting metal roofs and rust prevention is PERMAGARD® Elastomeric Roof Coating. This advanced coating forms a seamless, waterproof barrier that not only helps protect against leaks but also resists UV damage and temperature fluctuations. Its elastomeric properties allow it to expand and contract with the roof, preventing cracks and maintaining a strong seamless membrane over time. PERMAGARD® is suitable for various metal surfaces including steel, tin, aluminum, and iron, making it a versatile choice for residential and commercial applications.

For roofs that already show signs of rust, METAL-PRIME RED-OX™ is a game-changer. This rusted metal primer and sealer encapsulates existing rust, preventing oxygen from reaching the surface and halting further corrosion. Formulated with zinc and corrosion-resistant pigments, it bonds well to most clean and dry metal surfaces without the need for extensive grinding or sanding. Once applied, it can be top coated with elastomeric paints like PERMAGARD® or PERMAKOTE® for long-lasting protection.

Another standout option is PERMAKOTE®, a bright white, acrylic, ceramic-infused elastomeric coating. It also contributes to energy efficiency by reducing heat absorption, which can lower cooling costs in warmer climates.

Stopping rust on metal roofs requires a two-step approach: first, treat existing rust with a primer like METAL-PRIME RED-OX™, and then apply a durable elastomeric coating such as PERMAGARD® or PERMAKOTE®. These products not only seal and protect your roof but also extend its lifespan, reduce maintenance, and improve energy efficiency. For best results, ensure proper surface preparation and follow application guidelines provided by Nationwide Coatings.
