How to repair the decking and supporting posts?

[Laubi]

Hi all,

Looking to replace rotten decking and posts which support a porch roof of my shed.

I was wondering what the best approach in doing so and if it's possible to decking whilst temporarily supporting the roof.

Please note the posts in the middle are not that supportive and one provides no support.

I was thinking of temporarily propping the roof up in the middle with a couple of timber beams. whilst I repair/beef up the base frame; do the decking; and then replace the poles

A couple of Inverted L shaped supports would allow you to place temporary posts outside the footprint of the shed allow easier access to replace everything.

Thanks, do you mean something like this?

Unless it's the picture the roof appears to be sagging in the centre so probably needs jacking up a bit after you've reinstated the base.

Just to be clear, is that two timbers (c16 ok?) joined by a bracket. And the screwed to the underside of the roof? Should I screw the bottom to the base frame to be safe?

Yes, it's sagging as the centre-right post is completely rotted and doesn't actually bear weight!!
