zincalume is the cheapest way to go at roughly $12 per meter plus the flashing at about $10 pm. and a 5kg of roofing nails is less than $20. Its thinner but has a long life span. doesnt taint the water supply if you are planning to collect it. And there isnt any need to paint either.
But if you live near the sea I would go colour steel at $18 per meter plus flashing.
A tradesman can charge between 40-60$ per hour. And with having a flat roof its pretty straight forward and can be blown out in a day.

Less than 3 degrees! Is there anyone that will do that with steel! I don't think the manufacturers will give it any warranty under 3.

That was suggested on the other post. 3 deg is minimum pitch for iron. Best bet is to get a couple of companies to have a look and recommend the best way to do it.

Does colour steel taint the water

No.3 degrees is the minimum for SOME iron - namely trapezzoidal with ribs higher than 20mm. Standard corrugated iron - 8 degrees minimum

Have a look at the manufactures specs, the metal roofing manufactures guidlines and the nz building code. They all say no metal roofing under 3deg. In the old days it was widely done, but we have been reroofing alot of them which have been patched over patches, or trying to patch them over patches when the owners dont have the money to replace.

Yeah this is right under 3 degrees your looking at Butyl or Rubber type roofing or maybe a torch on type roof for a warranty, there are other alternatives too like heat welded pvc or Sarnafill (not sure on the spelling) Even the high rib Traydek roofing isnt warrantied under 3 degrees anymore
