Painting a Metal Roof

Q. I recently bought a Lake cottage in Florida, and the roof has been painted a pale yellow. I would like to change it to a Hunter Green. What are the steps I will need to take in order to do this? The house is approximately 30 years old, but I do not know how old the roof is.

First and foremost you must clean and prepare the surface of the metal by removing all loose paint, rust, dirt, oil, and grease. After cleaning the surface, Sand or abrade any remaining paint with sand paper or a wire brush. Clean the surface again, and remove all sanding dust.

Consult with your local specialty paint supplier, ask for specific recommendations for a primer and compatible top coat system to use for this application. They will also inform you of the ability to match a desired or custom color.

Please be aware that paints, coatings and solvents are chemicals and therefore you should always pay attention to proper handling procedures and be prepared to wear protective clothing, such as respirators, gloves, coveralls, etc. For further information on the health and safety requirements for the coatings and solvents you wish to use we strongly advised you to contact your local coating supplier. If possible, go the extra step and look for this information on the website of the product vendor.
