I used beltrands contractors inc (just looked it up) and this was 2019. I’m still in shock over their price and they went to multiple people for quotes. I think I went with this company because they did a few of my neighbors.

I paid about this amount 30k is insane.

Absolutely you can sue. Your contract is legally binding. I would talk to a lawyer at least. I know about 5 years ago I paid significantly less than you did on a similar roof in Hampden. That company is crooked in my opinion with having them call you with the roof off trying to get a ton more money. I work for commercial contractors which is different than home contractors but contracts are legally binding in both.
