White rust forms on the coating and it is very difficult to remove. If your roof sheets do get wet, separate each individual sheet. Use bearers to permit airflow around the metal. This will prevent the corrosion.

Gently does it
In terms of handling, care must be studied in order never to damage the paintwork. Sliding sheets across each other will damage them. When separating the roofing sheets, you must lift them cleanly upwards without scratching the one underneath.
