The secret behind the durability and aesthetic of a roofing system lies behind its surface finish. In the market, the most common types of finishes used in metal roof installation are zinc, aluminum, and paint coating.
During metal roof handling and installation, surface scratches and nicks are unavoidable. Installation tools and fasteners can damage the finish of your metal roofing. To avoid the scratch from reaching through the protective layers, it is recommended to use touch-up paint as a quick fix.
Can You Paint a Metal Roof?
Yes, absolutely! Just prepare the roof surface correctly, choose and apply the right products, and your metal roof will look good as new. Before the painting procedure, be sure to power wash the roof panels or scrub them to remove dust, mildew, and other residues. If you have a newly installed metal roof, they need to weather for at least 6 months before applying paint.
What Is a Metal Roofing Touch-Up Paint?
This type of paint is usually used to cover unwanted surface scratches and prevent corrosion damage. Metal roofing touch-up paint is manually applied after the baked-on factory paint finish. It is usually available in various color options that can match your roofing panels. If your metal roof requires touch-up paint, here are some of the helpful tips that you can follow:
Check the Damage
Before you start applying the metal roofing touch-up paint, you must first assess how big the scratch is. If the galvanized coating is still intact, then there is no need for touch-up paint. However, you’ve noticed a large area with damage, it’s better to replace the entire roof panel.
Choose the Right Touch-Up Paint
When you buy the wrong product, your metal roofing might encounter more issues. This is because you need to buy touch-up paint with the same quality as your existing finishing. It’s important to consult your trusted supplier or metal roofing contractor when you buy touch-up paint.
Touch-up paint is available in paint pens, small bottles, and spray cans. For small scratches, buy a paint pen with precise tips for easier application. A touch-up paint pen allows you to apply paint only on scratches needed. If you have bigger scratches or scuffs, you need a small brush to fill in the damaged area. On the other hand, spray cans are perfect for pipes and downspouts to apply the coating like a professional.
Do Not Overuse
Always remember that anything too much is bad. Using too much or wrong touch-up paint can cause issues with the already damaged appearance of your metal roofing. If you are unsure how to apply the product, reach out to a roofing expert for assistance.
Apply Touch-Up Paint Properly
First, depress the nib on a hard surface and wait until the paint starts flowing. Press the tip against the damaged panel to apply a thin coat. Always remember that you shouldn’t use a paint pen for large areas. Wipe any excess paint off and allow each coat to dry completely.
Small Bottle With Brush
Clean the surface properly and remove any dirt before you apply the touch-up paint. After this, brush the paint with smooth strokes. Apply the least amount of paint and use light pressure only. This helps you avoid using too much paint on the metal roof panel. Let the paint dry and do not retouch it after it has been set.
Before the procedure, wear safety goggles, a respirator, and gloves to protect your eyes and skin. Hold the spray aerosol can upright 10 to 12 inches from the surface to achieve a smooth film. Allow the paint to dry and continue spraying onto the surface.
