minimum pitch for corrugated iron roof?
Evening all,
I have been looking at replacing the roof on the lounge (it's already stuffed which makes me confident i can't do any worse).... and extending it out as a deck at the same time.
my problem is.... all the web searching on minimum falls and pitches for corrugated iron roofing has left me more confused than when i started. ive seen "standards" from 180mm over 9metres up to a whopping 1metre fall over 9metres.
now it would be great if everyone could go out in the dark and measure their roof pitches for mebut i dont think that's going to happen.
can anyone give me a rule of thumb for calculating the minimum fall of a corrugated iron roof?

Alll depends on the profile .... as little as 1°
Try checking bluescope steel website for the profile you want to use and it will give you the minimum pitch.Now proudly sponsored by Binford Tools. Be sure to check out the Binford 6100 - available now at any good tool retailer.

thanks everyone - my web searching skills suck, mystery solved though - general consensus is 1:12 for traditional corrugated iron

From an aesthetics point of view, I prefer a high pitch roof. If you are trying to sell a house in Brunswick with skillion roof on the back, you will get less money than one with a high pitch roof.

Minimum pitch for corrugated is 5 degrees. Trimdek profile goes down to 2 degrees and kliplock will go down to 1 degree.

pitch of roof
For corrugated steel roofing where the rafter length can be covered with a single sheet the minimum slope is 1:11 for lapped sheets its 1:8
When reality hits, it hits hard!

No one uses multiple sheets lengthways on roofs today unless it is over 21 metres which is the maximum length Lysaghts can carry on an extended semi-trailer.
When I worked for Lysaghts for 11 years it was, and still is 1 in 12 for corrugated.
