Guest User 12/13/2009	Our galvanized metal roof sustained damage from a neighbors fireworks display, the chemical residue reacted with moisture and we now have blotches everywhere that will rust prematuraly, in relation to the aging of the undamaged sections. My question is, this is a very new roof and I dont want to tear it up and replace it, can I just remove the screws and lay down another layer of the same material and re screw it? I would end up with a "double layer metal roof, are there any issues that I should be aware of?	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/14181/find/
Todd Miller Isaiah Industries, Inc. 12/19/2009	I would not do that due to the likelihood of damaging corrosion occurring betwene the two layers.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/14182/find/
