Got a leak that we haven't been able to locate. Thought it might be the mast where the electrical comes into the house and had that redone and still leaking. It's on the part of the roof where our solar is for the pool so I'm guessing a fastener has rusted or broken off and that's the source but I can't get back to that part of the attic to check exactly where it's coming in.

Any recommendations on who can do something like this?

Thanks
