Corrugated Iron- Will this work?

 I thought that the roof for the lastest building would be corrugated iron.
Remembering this from long ago-roofing the garage with it- I have forgotten the size of the stuff.
So, off to Mr Google and hey presto! Apparently, well today anyway, the sheets are 964mm wide giving a cover width of 914mm. The sheets are available in 6,8,9,10 and 12 ft lengths- this mix of imperial and metric doesn't make it easy does it?
So, working this out to my advantage, we need sheets 9mm x 18mm. I know it's not exact but who cares about a 3mm inch hear or there?

Turning to plastic sheet, I discovered a sheet that I had used to make lamp huts- not dead right but it gives the impression.
A few minutes with the snap off knife gives me many 6x3 sheets of corrugated iron.
The result on the left- not bad?
So the next thing is to cut a blank for the roof and start sticking on. One thing I will do is chamfer the long edge slightly to give an impression of the sheets overlapping.
Then out with the paint and try and create a rusty tin roof- more fun!
