how much does metal roofing cost per square foot?

hi, ok well thats wide Q. what profile? v-channel or orb? colourbond or galv? one side coloured or both? length of sheets?, hint longer is cheaper seconds or salvage yard or factory direct? weight ? yes, thickness and quality, goes by weight, (in aust the old orb is about double or more the weight of the new products) do you have a trailer/car? cos freight can be unreal. ask if a local passing carrier,truckie, can "backload" if you are not ordering a massive amount, and can allow delivery lee-way.( also sometimes a load is damaged in transport, the trucking co,s here, after insurance etc, usually keep the damaged goods, and if asked usually are happy to have a buyer! depends on your time frame! there is no "standard" length ,height,diameter or width.. on anything!Always remember that! a piece of string is better than saying..".that looks about right :-) " when buying any home repair item assume that and "measure thrice, cut once!!".
