Never consider using this business to work on your roof. As confirmed by NSW Fair Trading, he is not licensed to do this work. He caused nearly $10,000.00 worth of damage to my home and doesn't know how to restore a roof properly. He also collects GST (even though he's not registered with the ATO to collect it) and is likely just keeping the GST as an added bonus. When working at heights, he doesn't use any fall protection mechanisms and puts the health and safety of his employees at risk by not doing so. A very unprofessional business and one to avoid at all costs. Consider yourself suitably warned.
