How much is the going to cost me??!!
That's a tough question to ask---No one here has seen the broken truss---or the surrounding damages.
If you post a picture of the damaged area someone here could estimate the time it might take, but you will not get any useful pricing help.
So many things go into pricing that even guessing would not be doing you a good service.
