Will metal roofing rust?

You’re likely choosing a metal roof restoration because of the color availability and the long lifespan they offer; some have lasted 50 years or longer. However, if you moved into a home with a metal roof, restoration may be needed to fit your choice of colors and designs. 

Before you start coating on the paint, you need to check the warranty status on the current metal roof. If there is a lifetime warranty, painting it could negate the warranty. After that, you need to prepare the surface, this being an important step if you want the paint to last. 

Start with a professional power wash. The recommended pressure is 2,500 pounds per square inch to remove any mildew, mold, and any old paint. Because metal roofing comes with a factory finish that is baked on, you’ll need to apply a primer first. The primer will ensure that rust doesn’t come through and the new paint sticks. 

Next, you’ll want to use acrylic latex paint or oil-based alkyd paint. You’ll need a roller that is designed for corrugated panels and an airless paint sprayer to get an even coating.
