i can not tell you about their work but I can tell you, might want to think of your neighbors befor you hire these people. They show up at 7 a.m. every morning, so if you are a third shift person, or up with a sick baby, you can kiss all your sleep good bye for the next few weeks. they park their cars on your neighbors lawn, the park their port-a-potty in your neighbors yard as well. It is nice they do not smoke on the job site but go into your neighbors yard to enjoy their ciggs. It takes over 2 weeks to get a roof on so if you like a dry house your screwed. Also they leave their raido blareing all day long, until your ears are bleeding. Do not hire these jerks. read more
