Care of Metal Roof

We're preparing to re-roof our home and are considering metal panels. While searching online I came to a site informing that it is advisable to wash painted metal panels annually to control chalk, discoloration, etc. and lists what products should and should not be used. Is this a common problem with this product? Is this true that one needs to have the metal panels washed annually? I thought that metal roofs were virtually care-free and the benefits outnumber the problems.		Guest User 9/2/2011	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/16541/find/
In normal atmospheric conditions, I would say that most people do not do this. Occasional rain is fine to provide some cleaning. Look for a quality coating on your metal roof.

I would check with the manufacturer but pressure cleaning is usually acceptable.		Todd Miller Isaiah Industries, Inc. 11/3/2011	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/16544/find/
See response in other thread. Check with manufacturer and make sure you don't cause more harm than good.		Eric Novotny An informed customer is the Best Customer! 11/3/2011	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/16545/find/
