I might have to get a new roof. What is a good paying price, I live in the DuPage County area of IL.?

We have a leak in our dining room and can't figure out where it's coming from. So we called a roofing company and they came and gave us a quote of $6900, that includes the works, all new roof w/leak guard, new kitchen fan, new flashing around chimney, more vents and so forth. Is that a good deal. Does anyone know of a good company in the Bensenville, IL area? Thanks!
