Your metal roofing system is designed to last decades, but it’s not impervious to damage. It can sustain scratches and dents from storms or heavy, overhanging tree branches. If you're wondering whether to replace a panel or simply touch up the paint, the following guide can help.

Is It Time to Touch Up or Replace a Metal Roofing Panel?

Assessing the Damage

The decision to replace a panel or touch up the paint will depend on the extent of the damage your roof has sustained. Look for scratches on the paint coating—are they light or deep? Do they gouge down to the metal? See if you notice other damage as well, such as dents from hail or sizable tree branches. 

When to Replace a Panel

If the panel is scratched, dented, or gouged excessively, have it replaced. Touch-up paint generally fades faster than the paint baked-on during manufacturing, especially if the panel features a dark hue. Large sections of faded dark paint can look obvious from the ground, depending on your home’s size and architectural style.

When & How to Use Touch Up Paint

Use touch-up paint from your metal roof manufacturer if scratches are few. Manufacturer-provided paint ensures color matching, a benefit you will not enjoy from a big box store. Clean the affected area first with mineral spirits to remove any contaminants that interfere with paint adhesion and create unsightly results. Mineral spirits clean the metal without affecting surrounding paint or promoting rust. Once the area is completely dry, use a quarter-inch artist's brush or paint pen to avoid applying too much product and creating an uneven surface.

If you’re touching up a hairline scratch, or one that exposes the underlying metal, apply acrylic primer and let it cure before painting. Curing time for primer is usually 30–60 minutes, while touch-up paint loses its tack after about 30 minutes and dries completely within 24–48 hours. You might also want to apply several coats of paint depending on the thickness level you’re going for, in which case you must wait for each layer to dry.
