Painting a Metal Roof | DJ’s Painting

Coating a metal roof is not much different that painting a metal pole building. 90% of the time this metal is either a powder-coated, baked, paint finish or has a galvanized coating finish. These are great for long term outdoor exposure. Both systems hold up well to the UV and moisture over time. They also do a great job of protecting the metal from oxidation. These are the reasons why most people choose a metal roof. Metal manufactures claim that the metal never needs to be painted, but this is simply not the case. It is best to re-coat every 5 years for single component top coats and every 10 years for two component top coats. Our reasoning for this is that on a roof or horizontal surface, the single component paints will “weather away” at a rate of about ½ a millimeter per year after the first year. But for a 2 part urethane, this process is a little slower.
