These guys are horrible in terms of their work site. My neighbor used them for a roof replacement (they were not doing work at my house) and their workers were constantly disposing of nails, shingles and cigarette butts in my back yard. After the first day they left the site and packed up without cleaning my yard. They just left with dozens of nails all over the yard where my dogs would be walking. I had to chase people down by phone after first collecting an entire box full of their garbage. They had someone come back that night to go over my yard and stated they would check back several times day 2. They never did an their workers continued to throw construction material and cigarette butts in my yard. None of them seemed to speak English so I couldn't even communicate with them. To this point I still have not heard back from the person that came by the first night that guaranteed he'd personally be around to clean up. This sort of thing is unacceptable. I can't only assume this is a regular occurrence since I can't see any reason why this instance would be so unique.
