I have roofed numerous condo's and duplexes where the adjoining neighbor has no plans for a re roof.I live in a semi...my neighbor does not want to roof. How do I do my side?
VERY sound advice!I recommend if possible,safety wise both you and your neighbor to walk (his or hers) side of the roof.
I would document (written,pictures)any and all damage to any part of the roof on the neighbors side.Have the neighbor sign a letter of acknowledgment showing that they are aware of existing damage.
Doing that will ensure that you or your roofing contractor won't be blamed or accused for damage that was preexisting. Believe it or not it has been done.
Sorry I mean not to be strange or difficult but,,,,What???????,,,,,,,,I don't get it.make sure they did not make their roof. put some option to convince then also they will not agreed.
Then It is not so difficult to make only your roof.
