We had a leak in the roof of a rental property (WA) almost a year ago. Found a contractor on hipages.com.au who gave a competitive quote with a ten year warranty and had the repairs done. He sent a series of pictures (we couldn't attend at the time) showing stages of completion.
The first red flag was that the day the job was completed he was desperate for payment in cash - asked to meet at an ATM and kept pestering when told this was not going to happen.
After he reluctantly emailed an invoice we paid via bank transfer. Not ideal but it seemed he had done the job quite well despite his off-putting attitude. In that series of phone calls to arrange invoice and payment he kept repeating that he definitely works for company X even though I never questioned it. That was a bigger red flag. We later called the company (I don't entirely remember why) and the owner told us that he in fact does not work for them. Because the job had been completed, seemingly well, and the likelihood of improving matters seemed slim for little reward we left well enough alone.
Fast forward to today and the REA has informed us that there is now a significant leak in the roof. Investigation revealed that at least two of the tiles had been replaced by tarpaulin which has now disintegrated. I assume the damage will be covered by insurance but I wanted to know what is the best way to hold this roofer responsible.
