A Perth building contractor has been fined by the State Administrative Tribunal after a roof blew off one of its houses.
Osborne Park builder Danmar Homes was made to cough up $45,000, plus costs of negligent conduct for the dodgy roof work on two homes built between 2008 and 2011.
Both of the Mandurah homes received significant damage during a 2012 storm, with the front of one of the roofs completely blown off.
Parts of it were later found in a neighbouring yard.
Building Commissioner Peter Gow said Danmar Homes had been negligent by failing to comply with engineering details that would have ensured both roofs were fixed down.
"Flying roof debris may have struck and seriously injured or killed residents and damaged property, especially with the storm having occurred during daylight hours," he said.
"The two properties subject to this particular investigation are located close to the coast in elevated positions, so it is critical that the roof structures were constructed in accordance with the engineer's approved plans, which did not occur in this case."
Danmar Homes' unsatisfactory roof construction work was also brought to the attention of the Building Commissions four times between 2006 and 2010.
Danmar Homes and its supervisor Mr Robert George Williams have previously been fined for negligence and incompetence in 2002, and again in 2003.
The Building Commission will continue to monitor Danmar Homes and carry out regular audits and inspections on the company.
