Why do you care if he hired subs ? Was the price he gave and what you paid him acceptable to you. Was the job done to your satisfaction. Did you check to see if his men were covered under his NYSIF and if he was carrying liability ins.?I wonder what he's going to buy his Sub Contractor for the holidays? the man doing all his roofs as he pretends to play them off as his crew? I hope if I have a problem they will come back.
As far as coming back to warranty his work that's your problem. You chose him because you thought he was reliable. Did I miss anything ?
Now what's your f--ing problem
