Can you install weatherboards over corrugated metal?

Hi,

Is it suitable to put weatherboard cladding over corrugated metal to turn a shed into a white, Hamptons style cabin?

Or do weatherboards need to be attached to a smooth surface?

Thanks!

Hi @jascapp,

A warm welcome to the Bunnings Workshop community and thank you for your question.

The first thing you should consider is the additional weight that would need to be supported by the framing. Weatherboard will likely weigh more than corrugated metal sheeting, so it is likely worth having the frame assessed by a suitably licenced person, such as a builder or engineer, before proceeding.

While it is may be possible to attach the weatherboard over the corrugated metal, I imagine the metal would be compressed and will deform as the screws go through the weatherboard in to the frame. It would not be particularly difficult to remove the corrugated metal, so I'd suggest it is best to just remove it. This would give you a much simpler install.

Allow me to tag @Nailbag, @Dave-1 and @Jewelleryrescue for their thoughts.

Let me know what you think, and if you have further questions, please don't hesitate to ask.

Hi @jascapp 

I don't think I can add anything further to the comments by @JacobZ and his suggestion to replace the existing sheets, which will be a far easier method and one that has no issues with adding additional weights.

I also think that with multiple screw ins of the weatherboard over the corrorgated iron will make it deform and that it may show up when you are standing back and looking at the wall. (think of the way the nuts on a car wheel are tightened). You can tighten them all up but as you go then some of the ones you thought were tight all of a suddern feel loose again. I think this could happen to the walls.

Far better would be to remove the iron and then put weatherborad up on a smother non comprssable surface.
