Shoe prints on galvalume | Ask The Experts Forum

Adam Chirdo 10/6/2017	I recently had an unpainted galvalume standing seam roof installed on my house. Upon completion of the job there was lots of discoloration from where the workers were walking around but I was assured that after a couple storms it would wash off. Well 3 months later they are still there. I've tried using a power washer and dawn dish soap to no avail. Any ideas how to clean this off? This is on a majority of the panels. Also several panels were found with pencil marks on them.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22483/find/
Todd Miller Isaiah Industries, Inc. 10/6/2017	Have you checked with the manufacturer / supplier of the metal and/or the metal panels for their advice?	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22484/find/
