I was wondering if you could help. I got a quote from my brother-in-law to do my roof. I have two layers, & almost all the eves need to be replaced, and there is some damage to the wood under the shingles. I have about twenty to twenty-five squares, plus it is a little steep (a colonial style house). I just want three tab shingles, with a waranty of 20-25 years. If I contacted a roofing company, what kind of price would I expect? I live in Chicago Heights, IL.
