Make sure the roof is clean before you begin painting.
Spray painting a metal roof can reduce glare, provide a layer of protection and change the appearance of a building. Factories, barns and warehouses commonly have metal roofs. Most metal paints require two or three coats for maximum effectiveness, and you should only begin spray painting a roof if there is a very low chance of precipitation within the following 24 hours. Remove all rust spots with a wire brush or metal scouring pad before painting a metal roof. You can spray paint metal roofs with individual spray cans or a paint spraying machine.
Instructions
Primer
1. Place a sturdy ladder against the building and climb to the roof. Place all your painting equipment on the roof beside your ladder. This will be the last area you cover with paint.
2. Sweep the roof. Make sure dirt, debris and bird feces are gone before you begin painting. Spray stubborn dirt or bird feces off the roof with a hose.
3. Spray primer over the entire surface of the roof. Starting in one corner, use long, sweeping strokes to cover a broad area. Create a straight-lined pattern and work your way from one corner of the roof to another, keeping your back to the ladder. When you have covered the roof with your back to the ladder, you will have one section remaining that goes from your ladder to the side of the roof. Do not spray this area. Walk to the end of the roof and begin spraying as you walk back toward your ladder. This will ensure you do not step in primer.
4. Step down a few rungs on your ladder before completing the last section of the roof.
5. Allow the primer to dry for the amount of time prescribed by the manufacturer's directions.
Paint and Top Coat
6. Climb to the roof with your painting equipment once the primer has dried. Place your painting equipment near the ladder and ensure the roof is still clean. Remove any dirt or debris that accumulated since you applied the primer.
7. Spray paint in one corner of the roof. Use long, sweeping strokes. Create a straight-lined pattern and work your way from one corner of the roof to another, keeping your back to the ladder and using the same method you used to apply primer.
8. Step down a few rungs on your ladder before completing the last section of the roof. Allow the paint to dry for the amount of time prescribed by the manufacturer's directions. When the paint has dried, apply second and third coats as necessary.
9. Apply top coat once the paint has dried. Use the same method to apply top coat as you used to apply primer and paint. Allow the top coat to dry for the amount of time prescribed by the manufacturer.
