My metal roof has excessive chalking. The pitch of the roof is 9/12. What is the best way to remove the chalking.

You may be able to cleanse it with a mixture of water, detergent, and TSP. At one time there was a coating out which purported to fix oxidized surfaces but they seem to be out of business. Perhaps it did not work so well. Todd Miller
