We had our roof painted four years ago (September 2010). The contractor provided a ten-year guarantee. The paint is now coming off in patches. The contractor has inspected and says he will get the paint free from the manufacturer but says that we need to pay labour for the rework. The guarantee does not specifically mention that labour is not included and states that the guarantee covers 'that the colour top coat will not peel or flake over the guarantee period, that the product will not peel off the roof surface during the guarantee period, that the guarantee shall be deemed in effect over the ten year period if the aftercare instructions are carried out' The aftercare is basically hosing down every 12 to 18 months. Under the Australian Consumer Law, does he have the right to charge for labour?
