I support replacing the fastners (use stainless steel), re-caulk where necessary and forget the coating. The Galvalume will hold up for many years to come.

I have an industrial building constructed in 1995 with a 1:12, 24 gauge standing seam galvalume roof. I have had no problems with it, but plan to install a large solar array using S5 clips and would like to have the roof ready for another 20 years or more. I inspected it myself and found some of the fasteners rusty or backed out, some cracked washers. Caulking at the ridge cap is cracked.
I have had a couple of roofing contractors look at it, and they suggest replacing some or all of the fasteners, re-caulking, and low pressure wash followed by elastomer coating. These are people who have done these coatings in a lot of places, and they get the roof inspected at multiple points in the process by the coating rep.
But I am getting the impression on this forum as well as some others that I would be better off without the coating.
What do you think?
