Garden shed leaning forwards

[stealthwolf]

We have a 6x4 apex shed that the previous owners built. I'm guessing it's from tigersheds as there's a bottle of tigershed wood preservative that they had left behind.

For a while I've noticed the front of the shed feels lower than the back when I walk inside. I can't see any obvious rotting or warping.

I've measured using a spirit level and calculated that it's leaning forwards by 9 degrees. I suspect it's down to an uneven base.

How can I correct this?

What kind of base is it sitting on?

calculated that it's leaning forwards by 9 degrees.

If it's 6 foot deep (183cm), that works out that the back is 29cm (pretty much a foot) higher than the front!!

edit: if you mean it's 4 foot deep, that's still 19cm difference!

I think it's sitting up on concrete slabs. Will post up pics later. The shed is 6ft long, 4ft wide. The tilt is along the length.

9 degrees was a bit much so I went out and double checked, realised where I went wrong.

New figure is 2.7 degrees.

depending what its sitting on, you could empty shed out and either car jack it up enough one end to put more supports in or get some mates round to lift it enough to put some supports in. either way because the wood has prob warped to this shape any new movements may mean the shed may have gaps in it etc...

Got some pics today:

You can see the angle when you compare it to the fence posts

These are the slabs the shed is sitting on.

it could be the washing line causing the problem
it can cause the shed to rack forward and going diamond shape
measure the diagonal along the sides

The belt and braces approach would be to take it apart into sections, redo with a good strong level base, then rebuild. Might need to add some bracing if it's a bit warped. Not a big job, they come apart easily, but you will need new felt for the roof.
