And I do think there's more to the story here.
If I were in your situation, based on what is said here, and if I couldn't afford an attorney, I would negotiate with the board and see what can be worked out. Perhaps a long-term payment plan for the roof.
But you can probably find an attorney who would take this on for a few thousand dollars or so.

Why didn't you contact your attorney as soon as you received the assessment notification which would come before the roofing work started?
Sorry, but I have been on a condo board. We had to beg people to come to a meeting. Apathy runs rampant in most condos because owners don't understand that they have a responsibility to stay informed and participate.
