i live in Connecticut and i charge more then you but i am with Doug too. hold strong to what you want to charge for the roof. i get that a lot when i do estimates up here, people will say "oh the last guy did it for x amount, can you do it for that?" and i will tell them very politely, no, i have a business to run and that they shroud call the last guy to do it for that price and every time they say "oh, well he is out of business" or "i can't get a hold of him anymore" i wonder why?
