You will be fighting the spring in the roll which will try and return it to the shell. The rear arm is under spring tension so be careful.
Why not try and leave the awning out one or two holes on the main arms then retract it to the shell. That might give you enough clearance to get to the vent. It may not retract all the way, but it would be worth a try if it was me.

Ganglin, have you been on the roof lately? I had some odd leakers that turned out to be loose rivets and my biggest leak was the old TV antenae. Otherwise I would check the little awning rail and it's rivets, as well as the cooktop vent cover. Good Luck. george
Yes - just started taking on the roof after the stove vent problem.
The awning trick worked - it didn't seem to like it but it worked. Sealed the stove vent. When I pulled it loose it had sealer under the top edge but not thick enough to do any good. The edges were down with double sided tape. resealed the upper inside with Trempro and the edge with Parbond. I think the water was leaking in around the inner vent tube as the sealer was gone around that.
The curbside awning track is the original and had no sealer under it - sealed the top edge with two applications of Acryl-R. That leak has stopped. The other two awnings were added and have butyl tape behind the track - still going to hit them with Acryl-R on the top edge.
That started "well I might as well do the rest". Didn't take pics of the vents but let's just say someone had the attitude that more sealer was better. One had a 2 inch wide strip of sealer around and up on its base. Cleaned those up and just put a nice bead of sealer around the edge - topped the cap rivets with a dab of Alcoa gutter seal.
The vents are all done now. That leaves the antenna and the 12 holes that were sealed on each side of the A/C from the prior unit. Won't spoil that for you - I'll post some pics before doing them.
In the meantime - for your viewing pleasure - here's what I found under one of stack vents....
