I have a friend living in a building that her landlords are not going to continue to maintain. She needs to stay for now, though, and I offered to remove an old chimney in her roof that leaks in the winter. (When I took it apart, I discovered the roofing screws holding down the improperly installed chimney boot were taped over with packaging tape...)

On the property, we found a scrap of the same profile of metal roofing, and I am wondering if the best repair solution in this circumstance (where the landlords will not properly fix the roof) is to slip this roofing patch underneath the existing roofing, or if I should instal it on top?

I was originally thinking to put the patch on top, with two lines of high strength marine grade caulking (5200) around the entire perimeter, screw it on with roofing screws, and also apply a diagonal line of caulk above the patch on the original roofing to divert as much water as possible away from the new seam.

However, I'm now wondering if I should not put the patch underneath, and caulk all around the recessed edge.

I still lean toward putting it on top, but curious what others think.

Thought the wax ring needed to be replaced, but when I removed the toilet I noticed it wasn’t actually bolted to anything. In addition to the toilet leaking, there was also a leak coming from the shower handles (now fixed) that caused damage to the subfloor and walls in the living room below. Is there a way to repair this from below and anchor the toilet to something so I don’t have to rip up all those small tiles underneath the big ones and completely redo the entire bathroom floor? There’s a lot going on under there with some crazy looking patch work, wire, and concrete… I have no idea where to start.
