My neighbour has turned into an angry man over £50. Some background- I sought out 2 quotes, 3rd roofer never showed. Spoke to the neighbours, 2 were fine about it, 3rd was not happy at needing a repair. I mean we’ve only had around 8 or so storms since the last repair was done. There was daylight/possibly water entering my loft space. So anyway I had the roof repaired, going with the cheapest quote and sent each of the other owners a copy of the bill. Angry neighbour starts banging my door and shouting at me that this’ll be the last he contributes for “my roof repair” so I corrected him that it’s “our roof” according to the deeds. All split equally. He kept shouting and intimidating me so I told him to keep his money and asked him to leave. His response to this was to start ranting that he was going to have all his guttering/down pipes replaced and I’d be paying 1/4. I told him I would not be paying until I had checked the deeds and sought advice. As you can imagine angry man didn’t take this very well. I did try to explain that as we’re on opposite sides of the building his guttering only serves that side, not the side I live on and I wasn’t sure I was liable to split costs. So I guess my question is, am I going to have to give this horrible man a share of that bill? I’m in Scotland.
