Neither myself nor the owner had any idea that the decramastic tiles contained asbestos. I want to pay them and sort it out.”Supplied Hazmat says some versions of mastic or bitumen-based pressed metal roof tiles produced prior to the early 1980s contain asbestos. “Mastic or bitumen was the most common material used to adhere the stone chip to the pressed metal at that time,” the company says on its website. “All mastic or bitumen-based pressed metal roof tiles should be suspected of containing asbestos until proven otherwise. “Pressed metal roof tiles manufactured by other parties are believed to have been introduced and manufactured after the ban on asbestos was implemented, but the same care should be taken regardless for any pressed metal roof tiles which may contain a mastic or bitumen-based product.”Hazmat also says there are no risks associated with pressed metal roof tiles containing asbestos if they remain in good condition and are left undisturbed.
