does contributing some or all of this bill make me liable for future issues.
This is what you have to be careful to guard against. Remember, "no good deed ever goes unpunished".
The construction details are too complex to go into in a forum like this. If you pay anything at all towards the repairs, you should insist on a full release , which negates any admission of liability(again, an attorney is recommended) ,signed by the HOA, current owner and upstairs owner. My guess is that the HOA will balk at signing anything. I have my doubts that CR.S. 13-80-104 applies. What you did were repairs, not substantial improvement, which would be something like a room addition. No one has a "rollover" liability case against you. It is small money, and difficult liability. Most attorneys would decline it, but you could end up in small claims court, which can be very time-consuming. At least those are the main factors that I can see from this distance. Good luck getting it all worked out favorably.
I hope that I have provided excellent service and, if so, would love a 5 star rating. If not, please let me know how I can further assist you. There is no additional charge to you for rating me. A bonus is not required, but is always appreciated.
