Advice on how to get onto corner of unsupported roof

[lozcozard]

Not sure if this is the right forum for this...

I have this lean to roof that is polycarbonate sheets. But its leaking in the top right corner, the corner away from the front that I could reach on a ladder. The corner that has no sides for me to reach via a ladder. Its enclosed by walls. See attached picture.

I have contacted various trades people (builders, roofers) and either they dont turn up, dont reply, or turn up and propose silly & expensive solutions. So I am going to have to fix it myself.

Problem is the roof does not look very supported. I cant quite see what is holding the roof up on the right wall as its boxed in to hide the guttering which is on the side. I am going to assume its not supported enough to hold my weight at all.

I cant see how best to remove the roof sheets so I had this idea to support my weight...

I thought I could buy a few of them Acrow Props for the inside, to support some timber under the roof, then I could lay timber along the top of it then and that would support my weight then and I can get to the corner. As long as the props are secured suitably.

I wondered if anyone thinks that would work OK.

Thanks

I would prop the glazing bars near the box gutter using a scaffolding plank or similar then you could lay another scaffolding plank on top.

Yes thats what I initially thought, but then I actually wondered if underneath it needs to be a full plank, could just be several short planks. Does not need to span the whole underneath I mean.
