About ten years back, I was renting a house that needed a new roof. I was there when the roof was put on, but the bill went to the homeowner.
A couple of years later I bought the home. Now, I'm in the process of selling it and went looking for paperwork on the roof. The previous homeowner couldn't find any so I got a hold of the roofer. He couldn't find it in the computer files so went to his storage unit to look through old paper records. Nothing.
Looks like someone got a $10,000+ roof without paying for it.
