When it comes to the actual paint application, choose a day when the temperature is hot enough to dry the paint.

Preparations before repainting the metal roof
If you have finally embarked on your mission of repainting your metal roof, make sure to clean it by removing all the dirt, mildew, or scraping paint. You can use a scraper or putty knife to remove the flaking paint. During the exercise, ensure the metal of the roof remains safe; therefore, keep the blade steady.
An alternative method is by using a jet power wash that can remove the flakes and dirt with its pressured water. If you do not have a get washer, use your standard garden hose at high pressure. You can also dissolve existing paint oils and residue with a mild acid such as diluted vinegar.
If you still see an uneven surface, you can combine the above method with final scuffing with sanding paper. This method will even out the surface and also enhance the adhering ability of the paints and primers.

Working on Your Roof Safely
When you are painting your metal, ensure to tick boxes all the safety. Your careless attitude at this point can be hazardous. These are some of the safety tips when applying paint to the metal roof.
Use extension ladder
- It is wise to use an extension ladder instead of climbing on the roof. The slanting top can cause you to slip and come falling on the ground.
- Place your feet firmly on the steps and always make sure the ladder is steady against the support wall. Climbing on a wobbly ladder is an unnecessary risk that you should never take.
- When you are on a ladder, do not try to reach areas that are too away from your hand. Doing so, you can lose balance and fall. Instead, you can use a paint roller with a long handle to reach those difficult-to-reach patches.

Ask for the help of a friend
Instead of working alone to paint the roof, it is better to ask for the help of a friend. Your friend can hold the ladder when you are painting the ceiling. Thus, this is another way of ensuring your safety.
