Galvanized roof rust question | Ask The Experts Forum

Jon Galiza 2/29/2012	I currently have a really old galvanized metal roof. I noticed that there are different materials that were used on various parts of my roof to stop leaks. One thing I noticed was that anywhere where a tar-based material was used started to show signs of rust where as this other material that was used does not. My questions is what should I apply on a metal roof that stops leaks and does not create new rust. I used Henry 208 roof cement but I realized it started to rust around the edges of the tar patch. I know this may not be the correct material to use. Please help	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/17139/find/

David Stermer 3/13/2012	My experience is that field-applied coatings intended to fix leaks offer at best a temporary benefit. The best resolution is to determine the source of the leak and address that, whether it is deteriorated or misinstalled material, flashings or sealants.

Eric Novotny An informed customer is the Best Customer! 3/13/2012	+1 Solid advice right there. Top coatings for leak repairs are band-aid only fixes and should certainly be thought of as temporary at best.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/17143/find/
