The big one is our leach field. That needs to be done this year, and will require a professional as well as a large investment.
The shower drain pipe in the upstairs bathroom started leaking into our downstairs bathroom ceiling recently. There is currently no access to that pipe. I'm going to cut away a bit of the ceiling to see if I can get a look (and, if I'm lucky, even fix the issue), but that might end up requiring a professional as well.
We recently discovered some water damage in the upstairs corner closet. This will require me to pull away some sheetrock and see if I can determine the source. Hopefully, it will be something I can handle. I really hope it's not from one of the heating pipes .
Our metal roof needs a few repairs after this past winter. One of the snow diverters (I don't know if that's what it's called) was ripped right off when the snow started melting. There is NO way I am working on that.
And, of course, we have the beetle-kill tree problem. The number of trees affected in our yard just staggers me. I am definitely not equipped for that job.
I'm sure there's more, but this is already raising my blood pressure. I'm going to start looking at options next week.
