I have a 16" standing seam metal roof with vented ridge cap. Construction and maintenance safety ties were installed by attaching 2inch by 2/8 inch stainless steel fixtures to the roof trusses at various point along the ridge. There are about 12 safety ties installed. The ridge cap was cut to slip over the safety ties and the void around the tie was sealed with a 50 year sealant. The sealant has separated, mostly from the stainless safety ties permitting rain water to enter.
What is recommened as the proper way to seal these ridge cap penitrations?

What you have done is a little outside the norm, though it does not sound like an all bad idea.
Generally, sealant would be used in these areas. You need to make sure that the sealant you use is compatible with the paint finish and materials it touches. That is possibly an issue. The roofing manufacturer may have some advice.
I am curious where this all could have been done with an extra flashing behind these sfatye ties which would have stopped water that might try to blow up and in.

The stainless steel safety ties penitrate vertically through the ridge cap metal. Any rain water would run down the safety tie and through the broken seal. The cross section of the tie is 2 inches by 2/3 inch. I am wondering if removing the sealant followed by solvent cleaning of both the safety tie and the metal ridge cap would be effective. If so what solvent might be used that would not damage the finish of the ridge cap. Alternatly, is there a product like a flexible skirt that would slide over the safety tie and down snug against the ridge cap?

I am having a tough time visualizing what you have going on. Feel free to email pics to me at [email protected]
Also, what sort of paint finish is on your roofing system? You need to know that in order to determine the best sealant. What sort of sealant was it that failed? Silicone? Urethane? Acrylic? Butyl rubber?
