I am having a situation on a house that we purchased recently. I thought that the leak that was coming into the downstairs kitchen was from the plumbing upstairs. The upstairs hot water pipe was wet and it was about the right spot to be the culprit. However, we have not been using the bathroom and (it only seemed to leak when used) and it rained last night. Now this morning it is leaking again. I was thinking that it might be the roof. The roof is old and needs to be redone but was hoping it would last til next summer. I live in Michigan and a friend suggested just putting some tar on the roof to fix the leak and then next year deal with it. Does this sound like a good idea? Any ideas or suggestions would be appreciated.
