Elite Exteriors No Longer In Business

Not a bad price for the job however I expect to have everything done and done right. Shingles look good & vents installed as discussed but only one side of dormer has flashing (?!) and only one downspout was installed for the entire roof. A 2nd one down the back was discussed during estimate but they decided against during installation.
Promised to cover old clay downspout pipe in driveway, never did.
Highest piece of flashing fell off gable over the winter while I was away. (glad it didn't take anyone's head off) 2 months ago requested they put it back up. It is still not done and Steve no longer returns my calls. Guarantee their work? Lip service.
