Sweep the whole roof with a broom. Remove any debris and clear the dust.
Prepare cleaning solution. Mix three gallons of water with half a gallon of detergent in a small bucket.

Apply oil-based metal primer on the roof. Follow the manufacturer's guidelines of how to apply this primer.
Let the primer dry for a minimum of three days.
Apply an aluminum paint following the directions of the manufacturer. Apply a single coat with a soft brush. You can also use a paint roller or spray equipment, if the roof is very large.
Always follow the directions of the paint manufacturer. Always follow the directions of the primer manufacturer. Stir the paint thoroughly before and during the applications for better results. Do not dilute the paint unless advised in the directions.
