@Jessica Hinman As an investor, you work with many different contractors (plumbers, roofers, insurance agents, brokers, lawyers, etc.). 

You're likely going to end up with a sheet rock guy, a roofer, a flooring guy, you also need an insurance guy. 

Locally I hear stories about closed door meetings where the builders will promis X number of hours to each union (roofers, plumbers, carpenters....) and then after that, they can hire who they want, who may be cheaper.

I have a roofer painter few ac and general contractor.

Can anyone recommend a licensed roofer that can go less than that amount.  

The roofer will include a like-replacement of the rotten fascia board on the front facade as part of the scope.Gable resurfacing - the gable currently features tar paper, amateur trim work, and an ineffective plastic gable vent with no architectural significance.

Yes, write a letter, but you have nothing to apologize for when mending that fence.  

The main cause of the roof leak was from roofer hired by apartment management to replace their aged roof.

I am going to renovate it and flip it with the help of a carpenter/roofer (laid off for winter).

If you were planning on reroofing and the cost of the materials was cheaper than your quote, then just pay for the materials.however, if the roof was fine, and basically they just replaced something that did not need replacing, then yes, the issue would be between the other roofer and his GC (but i would eat the cost of them filling up the dumpster, as the cost probably wouldnt be worth the fight)Just my 2 cents
