I am replacing a rubber roof on my family room addition removing existing wood decking replacing rubber room and would like to use these tiles as flooring.Can these tiles be used?They wont damage roofing ?
The underside of the tiles are pointy plastic and would not be recommended to install directly overtop of roofing underlayment. You could put one of our additional rubber underlayment options (thicker) between the roof membrane and the tiles so that they wouldn't directly touch the roof membrane.
