Waterproofing around a conduit

[Jupiter01]

I am building a shed with a OSB board and a rubber roof. There will be a conduit coming through this roof and into the shed. Can someone help me with the detail around this entry and how it can be waterproofed please?
Thanks in advance.

I would be grateful for any advice you can provide with this please.

This is one way, others may have better methods.

How would this work when the conduit is very close to the wall and you have the bulky rubber that needs space?

I was expecting something far slimmer than the pipe boot you have linked as it wont have much space near the wall. Hope that makes sense.

Re-route the conduit so that it steps away from the wall, then you can use a conventional boot as mentioned. It would need re-routing to back against the wall once through the roof. This is all stuff you should think about beforehand.

Re-route the conduit.

To still go through the roof? I don't follow.
There are no options for a side entry as the side of the shed is some distance away.

Reroute it, so it steps out from the wall, enough to allow for that sealing method, then steps back to the wall - basically a dog-leg out, then a dog-leg back.
