Metal is a reliable, long-lasting roofing material, providing protection from the elements and promoting energy efficiency. Although metal is a durable option, it can rust, potentially resulting in leaks and pest infestations. Here are a few ways to prevent this problem and how a metal roofing contractor can help.

How to Stop a Metal Roof From Rusting

1. Galvanize It

Galvanized metal roofing has a liquefied zinc layer that adds extra protection and durability against the elements to prevent rusting. A metal roofing contractor will ensure that the entire surface is covered. A thorough application will keep any rust from forming and spreading across the roof.

2. Add Paint

Whether rust is already present or you want to take steps to prevent it, paint can help. The substance creates a barrier against the elements, especially if a primer containing zinc is applied first. For roofs with rust, use a wire brush and power hose to remove corrosion before painting.

3. Remove Debris

Ensure that debris is removed promptly to prevent dings and scrapes that can expose the metal. Once moisture gets inside, oxidation will lead to rust spots. When removing debris, use a soft brush to wipe away dirt or a leaf blower to avoid touching the surface.

4. Try an Elastomeric Coating

Elastomeric coatings are acrylic seals that can be added to metal roofing as protection against rust. Before applying, clean the roof completely. 

A single coat of seal can work for at least five years. These coatings are also available in a wide range of colors to match your home’s style.

5. Apply Sealant

A simple metal seal applied with a roller or brush can also protect the material. Use sealant designed specifically for metal, and coat the area where rust is present to stop it from spreading. For larger areas or the whole roof, a metal roofing contractor can help.
