Many customers ask us if we can paint galvanized metal roofing. The answer is yes! However, we can only paint galvanized metal roofs that do not have a zinc pre-treatment. Fortunately, any other galvanized coating on a metal roof is very simple to prep and paint.
In this post, our team at PRS Roofing in Debary, FL, provides a brief overview of how to treat and paint galvanized metal roofing. Since painting your roof is a hazardous task, we recommend hiring the pros to do the job rather than doing it yourself.
What Is Galvanized Metal Roofing?
A galvanized metal roof consists of corrugated steel with a zinc coating. The galvanized coating on the steel makes the metal more durable and resistant to corrosion and rust, extending the lifespan of the roof. It’s also fire-resistant and lightweight, making it a popular choice for commercial and residential buildings.
How Can You Paint Galvanized Metal Roofing?
Here is a quick guide to how we paint a galvanized roof.
Step One: Purchase Supplies
First, you’ll need to choose a paint color. As for type of paint, many people use exterior house paint, which is perfectly acceptable for galvanized roofs. Then, gather the supplies:
- Primer
- Paint
- Paint roller
- Tray
- Roller handle
- Metal putty knife (for repairs)
Step Two: Repair Any Damage
If your roof has any damage, you’ll need to repair it before you can start painting. Using new paint material and a metal putty knife, you can fill in any holes or rusty areas to ensure a smooth surface for the new coat of paint.
Step Three: Prep the Roof
Before you apply any primer or paint, be sure to prep the roof properly. You can use a diluted solution of 50% vinegar and 50% water to remove any oils or galvanizing from the surface of the roof. Next, use a power washer to blast away traces of dirt, grime, mold, and debris.
Step Four: Apply Primer
After you finish making the repairs, it’s time to apply the metal primer. Be sure that the primer you purchase is suitable for painting on your metal roof. Cover all exposed surfaces with an even coating.
Step Five: Apply the Paint
Once you let the primer dry completely, it’s time to apply the actual paint. Assemble your paint roller and handle, then paint a smooth, even coating across the roof’s surface. We recommend applying at least two coatings to ensure complete coverage and extra durability. For any small or hard-to-reach areas, try using a standard paintbrush or even a sprayer.
