We hired them to replace a leaking flat roof. The workers wouldn't speak English (except when they wanted something) and were unconcerned that they caused over $1000 damage to the concrete tile roof (caused by negligence). We were told that 1 row of the concrete tile needed to be removed, and that it would be replaced! They removed 2 or 3 rows and refused to replace it, they were so careless that they cracked two ceilings (one so bad the entire light fixture fell out!). There are now two very large leaks that weren't even there before they did the work. The owner won't return calls and when I finally got ahold of him, said that we were warned that this could happen and he's not liable!
