Leaking metal roof

I have a standing seam galvanized metal roof. At one time, there was an outdoor unit to a heat pump located on this roof. In order for this equipment to be level a metal block (box) was soldered to the metal roof panel on the low end of the slope to off set the slope. One end of the equipment set up on the box.

We have developed a leak inside that is in the general area of this box. The box has at least one and maybe two rusted through perforations. I suspect that water is getting through at those spots and leaking into the house, which means there has to be some type of perforation in the main roof panel also.

I am trying to figure out how to stop the leak. Since the heat pump is no longer located on the roof and that box is no longer needed, is there a reasonable way to remove it without causing damage to the roof area around it? Also, once I do get it off what is a long term way to repair what I suspect is a rusted through portion of the main roof panel.

Any and all help is greatly appreciated.

Thank you.

It sounds like that piece of roof metal needs to be replaced.

Thanks for responding. Can one panel of a standing seam roof be replaced?

I think so, while I've painted a few standing seam roofs, I've never installed one.

I don't get on roofs anymore, but what I have seen is a complete section or sections of roofing overlayed the offending ones, and the seam crimped over both, from edge to the ridge. This would be better than removing the old ones, IMO, since the damage is isolated. Of course pictures may help us give better advice.

As far up as your brackets are, someone could remove them, and overlay a shorter (6' or so) piece over, sealing the lower edge and crimping to the standing seam part on the sides. The brackets definitely have to go.

How would the brackets or boxes be removed? It is a little hard to see in the pics but the seams are rolled over as they get to the top so that the metal bends up the wall to create flashing. How would a new panel be laid over the standing seams when they roll flat at the top.
