3 rental properties need new roofs. How do I deal with roofers?

[Kieran Donahue]

Due to recent hail storms I need 3 roofs replaced.  I've called a variety of roofers and they all seem to want to scam me one way or another.  I've called a couple of them on their pricing.  Most of them act like the insurance money is theirs in the bag.  They all want your insurance estimate so they can squeeze more money out of the insurer while giving you the lowest quality/cost replacement materials.  I had one just tell me I couldn't opt for the upgraded shingles because my insurance wouldn't pay for it and he didn't get a bulk discount to buy the shingles that I want.  I have 3 checks for $7,000, $7,000 and $8,000 to replace these roofs completely.  How do I get some good quality impact resistant shingles and not have to put up with the BS?  Someone must want the work in Dallas, TX?
