How to Paint a Metal Roof



First, the chalk and oxidation need to be scrubbed off.  Abrasive pads that will remove the chalk but will not scratch the paint are included with the kits below.  Once the chalk is removed and the metal roof looks good when it is clean and wet, then 2 coats of primer  are applied to restore the cover any rust spots and provide a good base for the metal paint.  A rust-buster paint can be sprayed on with a paint sprayer or it can be rolled on with a microfiber roller.

Apply Primer

Once you have the primer, apply it according to the manufacturer’s instructions. Allow it to dry completely before applying any paint.

Apply Paint

Apply a premium paint and primer to a galvanized roof with a paintbrush or a roller specifically designed for corrugated metal. If crawling around on a metal roof in the hot sun does not sound like an ideal way to spend an afternoon, rent an airless sprayer to complete the project. Not only does a sprayer do a more thorough job than painting with a brush, it allows you to minimize the amount of time spent on the roof. If you spray, choose a windless day to paint.

Painting a galvanized metal roof can be time consuming, labor intensive, and potentially dangerous if you don’t know what you’re doing.  It’s highly recommended that you at least consult with a professional roofing contractor who is experienced with galvanized metal roofing.



Roofing is one of the home improvement disciplines that is most prone to scams. Scams are found in almost every business but scams in the home improvement sector are among the most hated. These scams can leave with problems that would cost you a lot to fix besides being scammed thousands of dollars. It is important for you as a homeowner and roofer to know the signs of roofing scams. Here are some of the roofing scams.

  • Scam #1: Inadequate repair

It is difficult to spot inadequate repair roofing scams until the scammer is already gone. When you pick on the cheap roofer to fix your problem, you may be excited shortly until you realize later the shoddy work that was done. This roofing scam is challenging to identify since most roof problems occur below the surface and therefore someone can just put on new shingles without solving the real cause of the problem. This may make your roof look good but after a short while you realize your roof performing worse than it was before.

  • Scam #2: Service overcharge.

This is one scam that is easily avoidable. A good roofing company will always charge a reasonable price for their services. You can tell a reasonable quote by getting the average cost from quotes of four or five contractors.

  • Scam #3: Unnecessary repairs.

Unluckily, since most roofing issues are the likely causes of subsurface damages, it is also difficult to spot this. It is difficult for an average homeowner to differentiate between unnecessary work and thorough service. You may not even notice that you are a victim of this.

How can you avoid roofing scams?

One way of avoiding roofing scams is by contacting multiple contractors before you choose on one to hire. This will help you know the cost and time estimates and help you identify any dishonest roofing company from the rest.

Another way is by keeping a close eye on your roof condition. This will help you identify any problem on time and take your time to get the best roofing company.
