Effect of foundry gasses on roof corrosion

Q. I am running a small business which include an aluminium foundry. We use green sand and melt the cast aluminium by use of an anthracite furnace. Our geographical site is inland, dry and shiny.

The zinc-coated steel roof is corroding quite fast. I expect it is caused by the fumes. Will you help me in knowing:

1. what is the possible chemical reaction that cause the problem?
2. how to solve the problem?
