Epic Quality Exteriors

This company re-roofed our home so we thought we'd use them again...big mistake. Our roof looks fine, but i'm no expert so i just have to hope they did it right. After the work they did on our shed I am very worried about the quality of work that is on my roof.  They tore out our shed floor and pushed all the moldy pieces of presswood under the new floor to cover it up, they didn't even bother to try to level the old floor, just left the old rotten braces there, and didn't even remove the old nails, they bent them over and nailed their boards over the top!!  In the doorway the floor was more than an inch out of level in an 18 inch span!  They did not use osb made for a floor, they used 1/2 inch roof sheeting!  the quality was so terrible we had to rip up their floor and re-do the entire floor.  we couldn't even reuse their materials since they weren't the right materials so we had to pay even more out of pocket to be able to fix the floor.   They also left all the torn out materials in the middle of our yard so now we have dead spots of grass that looks terrible. He told me i should just burn the pile, but the boards were full of nails so we coudln't burn them unless we wanted to have nails left in the middle of our yard!    He also said there needed to be a vent near the top of the shed, well he found an existing hole so he decided to take a shortcut and just put the vent in that hold. He didn't even cut it out to fit the vent, just left the 4in diameter hole instead of cutting it out to the 12-14 inch square that it should have been.    He showed up 3 hours late, at least he called, but since he came late, he was rushed the whole time he was there because it made him behind on other jobs so he cut corners and did a very lousy job. My brother in law almost fell through the floor the first day! There were also nails that were already backign themselves out in the doorway where they tried to nail it down so many times to get the board to stay down. (but when the joist is an inch higher than the next one to it that will never work!)      They agreed to come back and fix the job and make me happy the following monday, but we waited for hours and hours, never got an email, not a call, nothing.....he just never showed. I emailed several times just asking for my money back but he never responded.   Finally i called when i was in the courthouse and gave him one more chance to make things right, he said the work they did was fine and that i was a liar and then he hung up on me!   so I finished the paperwork and filed for a court date.     the pictures don't lie, and the fact that he has removed his website and all of his ads and is now trying to sell his company tells me he doesn't even believe in fighting for his cause, he obviously knows he does poor quality work and doesn't even want to stand behind his own guarantees.  He guarantees satisfaction or he will come back and fix it himself...this is not true!
