How to Fix Roof Paint
- 1). Clean your roof. Sweep any debris from the roof with your broom. Mix four gallons of water and 1/4 cup of dish soap in your bucket. Mop the roof to get rid of any dirt or debris not removed by the broom. Rinse away the soap with clean water.
- 2). Scrub rust spots on the roof with your wire brush. Remove as much rust as possible. Sweep, mop and rinse these areas thoroughly. Rinse out your mop and allow it and the roof to dry completely.
- 3). Apply a thick coat of roof paint with your mop to any spots that were rusted or any spots with particularly bad stains. Allow the paint to dry for one hour. Leave your mop in the paint while you wait to prevent hardening of the mop head.
- 4). Apply a thick coat of paint to the entire metal roof with your mop. Take your time and work from the peak of the roof down. Completely cover one side with roof paint. Move to the opposite side of the roof and coat it with a thick coat of paint. Allow the paint to dry overnight.
- 5). Apply a second coat of roof paint to the roof. Allow it to dry completely and caulk around any vents or protrusions in the roof.
