I have all the materials from a kit, but I cant seem to get a roof plumber to quote the labor. Doesn't help I'm in Eildon Vitoria. I already know about the requirements and legalities so not really practicable to do it myself that's why I'm looking for a quote or even someone who would sign off if done myself. (not the first colorbond roof I have done). 12by 11.8 holiday house.
